Real Estate Show - Interview Jim Ritter with 3D Printed Farms
Well, Hey there everybody. Welcome back to the real estate show. I'm Alice Lema.. I'm a broker here in beautiful Southern Oregon with John L. Scott real estate, your host for the show. So glad you could join us again today. We're gonna rebroadcast our 3d technology interview with Jim Ritter, the founder Printed Farms, 3d Construction. And he came and spoke with us briefly last spring. And, you know, we may start seeing some 3d technology in Southern Oregon in the next year or so. So we wanted to bring this back and just remind you of interesting things that are being done.
Now, if you're not aware of 3d technology, it's computer driven, they use a slurry type material and they can build, they can do construction of commercial buildings. They can do warehouses, they can do shops, apartments. It's really, really cool. So I hope you'll stay tuned and listen to Jim Ritter the founder of Printed Farms, 3d Construction Company.
And and in the meantime let's check briefly on our local stats, cuz we did have another volatile week. And right now just a reminder we're checking week to week and we are doing residential only. So this week in Jackson county, our active listings are up 56% from this time last year, but of that our new listings are actually down. So this 56% increase you're seeing in active listings in Jackson county from this time last year. Those are listings that have not sold. And they've been on the market for a while.
Josephine county, similar situation. We have an increase of 37% from this time last year on our active listings in Josephine county, but they're not new ones. The new numbers for Josephine county, the new listings are down.
And the same for Klamath County is only up 3% from this time, last year of total active listings, but they also had a decline in new listings. Now some of that might be summer. Some of that might be just, people are nervous about all the weird stuff happening in the world, but we're showing some volatility and, you know we could use some more new listings.
So if you're thinking about selling. Please contact your agent and get that place on the market. Because right now we're kind of stagnant. We just don't have enough new ones. Let's talk briefly about our sales. Our solds here for Jackson county are down 37%. From this time last year, our solds are down in Josephine county 30% from this time last year and our solds are down 28% in Klamath county. So yeah, lots of volatility. Still a lot of opportunity. Interest rates are fluctuating, sometimes are up, sometimes are down. So just keep in mind, there's always an opportunity somewhere in real estate land.
So with that in mind, stay tuned for the interview with Jim Ritter from Printed Farm 3d technology, we'll be right back from a quick word of our sponsors. Don't go.
Well, good morning again, Southern Oregon. And welcome back to the real estate show. I'm Alice Lema. I'm a broker here at John L. Scott Real Estate beautiful Southern Oregon. And I am so excited to bring to you, Jim Ritter. He's the founder of Printed Farms in Wellington, Florida Palm Beach county.
And he's gonna bring us up to speed on the new technology. 3d printing, creating more housing. Jim, thank you so much for being on the show today. It's a pleasure. So just to kind of get started cuz in Southern Oregon, we don't have this technology yet. Can you maybe give our listeners just a little thumbnail about what it is that we're doing with this alternative?
Well, good morning again, Southern Oregon. And welcome back [00:03:00] to the real estate show. I'm Alice Lema. I'm a broker here at John L. Scott real estate, beautiful Southern Oregon. And I am so excited to bring to you Jim Ritter. He's the founder of Printed Farms in Wellington, Florida, Palm Beach county. And he's gonna bring us up to speed on the new technology, 3d printing, creating more housing. Jim, thank you so much for being on the show today.
Jim Ritter: It's a pleasure.
Alice Lema: So just to kind of get started cuz in Southern Oregon, we don't have this technology yet. Can you maybe give our listeners just a little thumbnail about what it is that we're doing with this alternative building.
Jim Ritter: What we're doing with it is we're taking the trades that we're losing through an aging out process. And the machine does what the trade used to do it squares and sets up the building. And the machine also puts down the layers by layers, better material. So [00:04:00] we're actually a, a stronger, better material building than a stick building, which is wood and or block. So you have to equate us to a solid concrete structure.
Alice Lema: Wow. So how, so there's so many questions, like what is this material that you're talking about?
Jim Ritter: It's a specialized concrete mix because it has to set up within a certain time to support the layers that come on top of it. And so because we don't use forms or, and, or we are the forms on the project. The material is a complex cement mixture, but usually has a higher cement ratio than an, the normal ready mix. So we'll have up to 10,000 PSI, whereas a ready mix will be 2,500 PSI.
Alice Lema: Wow. That's huge. And so now in Florida how did you get started doing this? Was it because of the hurricanes.
Jim Ritter: Primarily because of the loss of trades and the quality of [00:05:00] the trades to put up block buildings. I was doing some developing small developing of horse farms. This area's famous for horse farms and to get the quality builders was impossible and it's a shortage that everybody has experienced.
And so I looked around for alternative ways to build. And this is what was on the horizon. So I decided to jump in.
Alice Lema: And so just as our listening audience understands, we're talking about creating buildings out of a concrete type mixture. That's. In a soft form, like ready mix and that's poured on the ground and stacked on the layers are stacked on top of each other vertically. Is that how you'd say it?
Jim Ritter: No. What we do is we take a dry mix. In a silo and then we put it through a mixer pump system. Then we pump that material into the head of the printer, just like the printer in your house, you know, the copy machine and [00:06:00] like your copy machine, the ink is very expensive. So the printer is one cost. But the ink right now is not scaled up. So there's different inks as we call it or print material that we're testing for large concrete companies, plus some materials that we're using. And that material comes to the head of the printer. Just like you do in your house. And layer by layer it makes sure like any 3d printer, it, it builds the shell of the house.
We only do the shell of the house or, or print the forms for the beams or the slab, or you know, the form for the, you know, the beams of the roof or something like that. So we don't, you know, this idea that we print the whole house is not valid. We print about 35% of the house, but while we're printing, we incorporate a lot of things where we add in the insulation, the boxes for the electrical, the conduit for the [00:07:00] electrical, the rough plumbing.
This way there, you're not waiting on trades, which is also a big cost if you have a lot of downtime. So as we're printing, when we're done, if everything is organized and you put your windows and doors in, you have a closed system that can be finished by the general contractor inside and outside, because everything is incorporated. What we call closed shell system.
Alice Lema: Well, that is just amazing. It's just amazing that you can do that. And so 3d printing of a house what kind of size dwellings are we talking about, being able to create?
Jim Ritter: Right now our machine can do about 1600 square feet, two stories, so total we would say.
Alice Lema: Wow, you can do two stories.
Jim Ritter: Yeah, we can do a two and a half, but we, we stick to two. We do have, of course in south Florida, high wind velocities from hurricanes. And Miami Dade is one of the toughest code systems in America. So there's some technical issues as we go up on walls that are 15, [00:08:00] 20 feet high. You know, single stories, but we can print up to about 30 feet.
We, we push people, putting flat roofs on that. We pour the concrete with the machine and by doing this, we take a lot of people off the second story and those floors. So there, the accident ratio is much lower because there's no one there.
Alice Lema: Yeah. Yeah. Wow. So it's safer. That is so interesting. So with the labor shortage, I, you know, you were talking about that's how you kind of got, got into that too. And we just had huge fires here in Southern Oregon and we lost 2,500 homes in just a week. And we're still trying to recover from that. And the trades are stretched thin and then this was after the pandemic.
So when you brought this into your county and started doing it you were doing it to replace labor, but the labor that was already there, did you get any pushback or did you get any attitude from people. [00:09:00]
Jim Ritter: No, because we're not big enough to impact. There's so much. Florida's one of the fastest growing states in America. In fact in January 50% of the jobs came through Florida for the United States because we have a boom. We're in a huge real estate boom in south Florida, us. So everybody is so busy. No one really cares. We're trying to build better buildings. We also just lost 1100 houses in the north of Florida, the panhandle area due to forest fires. So that is what we're trying to do is build greener, better buildings that will survive these catastrophic events, which we know are happening due to climate change. In Florida of course, flooding is huge. They're building sea walls, cuz if we don't, we're not gonna be here.
Hurricanes are more intense as they see. And then of course we have the forest fires like you have. And concrete homes right now are the.best way we have to [00:10:00] build habitats that will survive these catastrophic events. And 3d printing makes that cost effective. And so we're not cheaper. We're not, you know, we're not always faster. It depends on the, on the project, but we are much superior in materials and quality of building.
And I think that's very important for people who've lost a home and they can't just keep going to their insurance company cause they get dropped. Right. They dropped 50,000 people in Florida alone on insurance because of the, the worry about costs. So all these factors come into play and why 3d printing will be better in the future.
Alice Lema: Wow. Wow. So when you're putting the, a closed system together, you were talking about electrical plumbing. What about heating and cooling? How is that incorporated?
Jim Ritter: That's incorporated a conventional way. We don't do the ceiling. So your [00:11:00] map system if your readers, if the listeners don't know map is mechanical electrical plumbing. So we leave the ceilings open. And of course your air conditioning down here where we are, we go through there or your heating ducts. Your plumbing is conventional.
It's just because the machine is doing most of the work. We have a crew of about four people and they set the ladders in the walls. They set the boxes in the walls. And so the next day, you know, and when we get to a certain point, we run the conduit it's just easier and faster and cheaper. That's how we save the builder money.
Alice Lema: Wow. Wow. That's just incredible. And then it's more earth friendly and more disaster proof.
Jim Ritter: Well, if you're concrete companies and some of the ones we're dealing with produce carbon free concrete by burning waste or whatever they do, then concrete buildings are carbon sinks and they, they obsorve carbon for the rest of their life.
So they are very green. [00:12:00] Obviously because we have a denser material and an airspace where we're a better building for insulation. We're tighter than block. As far as water seepage or permeability to water, this is very big when it comes to rebar rusting in buildings, because that's a huge problem in Florida if you saw the disaster in sunrise. And we feel by printing this envelope in the building and putting the rebar in the middle, we mitigate that problem because the rusting comes from the salt air coming in through the building.
Alice Lema: Mm-hmm very well thought out. And so when the consumer goes inside of a house, is there drywall, do you have the rough leftover of the concrete? What, what does that look like?
Jim Ritter: We try, try to take drywall out of the condition. I'm an anti drywall freak. I hate it. And so what we do is we print the interior and the exterior walls. So we don't have studs to carry sound. The walls are stronger. I [00:13:00] believe in the old plaster methods, plaster your interior walls.
You can leave your walls rough, but as my wife says, who wants to clean it?
Alice Lema: It has like little grooves in it.
Jim Ritter: Yeah. So I like a smooth finish, but that's up to the individual. But we print the interior walls and the way we do the doorways and everything, it gives a very inviting way, to put in good walls, have a very soundproof house or sound resistant house throughout. It's a much stronger, nicer feeling.
Alice Lema: Yeah, I was thinking. And when you said denser than the old school plaster, those houses were somewhat soundproof sound, tapped down the sound and their insulation value was quite high. So what are we talking about in that department for these 3d printed homes?
Jim Ritter: We don't have all the data, but the, the buildings we've done without insulation, we, we feel we have a 12 ,R 12 with just a dead air space again, because you don't have that movement of air through there.
But with insulation, we could easily [00:14:00] get 20, 25% for the walls. And of course the roofs you would do standard for your area so depending on your climate.
Alice Lema: Mm-hmm so are you putting insulation in the ceiling then? Is that what you're talking about?
Jim Ritter: And I mean, we used an ICF system on one of our sheds.
So that has a standard that's insulated concrete forms. And that has a standard R value, I want to guess around 25. That's the roof for the shed we did on a one agricultural shed.
Alice Lema: Wow. Well, super cool folks. You wanna stay tuned? We do have to take a quick break. We get a word from our sponsors. We're having the most amazing conversation. 3d printing of houses, sheds and buildings. Jim Riter the founder and CEO of Printed Farms of Wellington, Florida. I'm Alice Lema, your host for today. We're brought to you by Mutual of Omaha, Guy Giles the lender in house. We have John L. Scott, Medford, and Ashland, and also our local Rogue Valley Association of Realtors do not touch that dial. Jim Ritter, [00:15:00] the founder Printed Farms, 3d house building will be right back.
Well, welcome back everybody to the real estate show. I'm Alice Lema, broker John L. Scott here in Southern Oregon. And today we're talking to Jim, Ritter the founder of Printed Farms, 3d construction. He's out of Wellington, Florida, and boy, what an eye opening conversation. This is Jim. I cannot thank you enough for being on the show today. So not only did I learn already about how green friendly this construction is, but it's really cost appropriate compared to what you would pay to have a is that what you call it conventional construction done?
Jim Ritter: Well, it's a superior building. You can only compare it to another concrete building. And for very large buildings, we are working on some tilt wall systems with the 3d printer that we could incorporate the two. Because making the forms for tilt wall is very expensive, but for, because of our freedom [00:16:00] of design, it's very inexpensive for a 3d printer.
So we're exploring that route for very large buildings, but for your standard home, which is about 2000 square feet, mm-hmm we 3d print it. The only per problem is, is we don't have that many printers out there. We don't have a lot of builders doing it and we're, we're still learning the process to print quickly and effectively and cost effectively.
I mean, to make it more commercially viable. So right now, because the machines are custom made, the print material is made in small batches is we're not scaled up. So we haven't met, met our price thresholds that a lot of people are alluding to in their videos and everything else. We're not there yet, but it's coming.
And like any other industry, whether it's the auto industry or any industry, these are just large robots who do the job and they're a tool. That's all they are. They, you know, really we're building conventional [00:17:00] using this tool and using a new material. Other than that, it's all the same. But it produces in our mind a much better house for the future.
Alice Lema: Well, and the idea that some of the ingredients in concrete absorbs carbon that is an amazing thing in this day of climate change.
Jim Ritter: Well, we currently in our building, we, we use no wood. Even the box for the windows. If you're permitting, allows you to tap on right into the cement. For the windows, that's the best Uhhuh, but if they require a box, we use a Hardy board, which is a cement product. So when we're done with a house, there is no wood in the house and wood doesn't go well with south Florida. I don't know Oregons climate or building, but for Florida, it's, it's a very salt, humid environment and wood just rots. It doesn't matter what you have. So we take wood out of the [00:18:00] equation and by building these cement homes, we really feel they're a superior building.
Alice Lema: So, and if you're gonna spend the same amount of money approximately, and you can have this superior building, I just think it's a no brainer that this is where people are gonna go. And then you don't have to have as many work, work people. You don't have to have as big of a crew and you don't have to have the delays cuz that's part of what we're struggling with.
And you said you had fires in Northern Florida. So you know what? This is like, you just can't get anybody to do anything on time, much less at all. Just we just don't have the bodies. So this would replace some percentage of the labor force. It already is.
Jim Ritter: Well and it, that is all very true, but you do have to bring it up to scale and scale it up and bring it in to the mainstream by training people. You still gotta train this group of four that interact with the machine and, and do everything.
And that's what we're doing. We working with the [00:19:00] US Airforce, took a machine and we're helping them. So we train everybody. They get the machine, we train them, we give them the knowledge we have about building. We tell 'em how we got it through permitting. And by doing these steps, yes, you end up with a better, a better building.
And all the printed farms did is we took the machine and said, okay, what can the machine do today? Not what it can do in the future. And today it pretty much prints the walls and pours. We can pour the slabs and that. And in any concrete building, you have three to four different concretes that go into that building.
Your slab material, your, your beam material, your roofing material. If you have a lightweight cement roof system. So it's not one material. The machine has to interact with several different materials and, and utilize those materials to the best ability. And that's what we've been doing a lot in Printed Farms.
Alice Lema: So do you so do, [00:20:00] if somebody's buying, let's say I was gonna buy one from you, which I might. So if, if, if someone's gonna buy one from you, do I bring my own four person crew and we go to Florida, get trained.
Jim Ritter: Yeah, we would prefer that, that you would that we would train your crew. I mean it all depends on obviously the contract, but it's not that difficult. I mean, we did two week course with the air force and they're printing their second building.
Alice Lema: Are they really?
Jim Ritter: Yeah. They're they also were hit by a hurricane and they lost a lot of buildings. So they're gonna do a lot of barracks and things like that. But the bottom line with it is it's not, yes the machine is complicated, like your car today, but to learn to run, it is not that complicated. And I have no background in 3d printing. When I got outta high school, we were still doing keyhole punching. So it's you don't have to be a rocket scientist to run these systems.
But it does help actually [00:21:00] to understand the materials and be very good with concrete because it is still concrete and concrete is one of the more finicky building materials and unlike pre-made materials that come to you like Lintels and block and everything, you're manufacturing on the spot. So weather and everything else can influence.
Alice Lema: Like temperature and humidity and wind and all that. Interesting. Interesting. So Would it behoove me or some other person who wants to buy one of these machines to bring the four person crew and have them already with a background in concrete. Is that kind of who you would want me to put together?
Jim Ritter: I think one person should, would be good ,that at least one understand concrete and how it works. Uhhuh, you know, basically you need some real building people on the job because you're still, we still use ladders for building the walls to keep the stiffness to the walls as it sets like conventional building. You still gotta set your boxes and everything's so there is a lot of conventional [00:22:00] building that goes on. You still have some shoring depending on your roof system or, or the size of your door opening. We've gone as wide as nine feet for a door opening so that supported while we poured the beam, just like conventional.
So you know, the, again having people who have done building and understand it, but then you need that person who likes to play with CAD which is the system usually used and understands the laptop and all the programming. So they can, you know, on the fly, fix it and adjust anything the machine might need.
So, you know, we, we like to get a kid who's really into that 3d printing has a 3D printer at home. That's always great cuz they run the laptop and they're really into that. And then I bring the building group.
Alice Lema: Okay. So it is a team you're putting together a team and then they're getting trained.
Jim Ritter: It's a team that has to work together and synch together because as one [00:23:00] GC said, I never had to go so fast cuz now you gotta keep up with and the machine is going and you've gotta lay this stuff in and down and you gotta be ready for it. You can't just be sitting around and go, oh, I forgot which they did in the doorways. And we do certain things in the doorway so that the doors you order fit and they, well we block it out, so make sure that it measures because you do have some over extrusion of the material.
And even though it's, it's programmed for, and it's doing the right thing, you, you could get more material in that opening that it's not a three and a half foot opening or 40 inch opening. Now it's a 38 inch opening and you order doors for 40 inch opening. So of course so we have a system for that also.
And we don't use pre manufactured lintels. We make 'em on the spot. So there's a lot of stuff that we we've incorporated that we help people with. And just saves you making our mistakes.
Alice Lema: Yeah. So you're putting in [00:24:00] traditional doors, traditional interior doors, traditional interior windows.
Jim Ritter: Interior exterior, one of the beauties of 3d printing is we have rounded corners. So on exterior doors, instead of having to set 'em out towards the outside so that they can swing open, we can set 'em in the center and they still have more swing than you would on a conventional building with square corners. Yeah, there's a lot of cool things that come out of printing that I would call serendipity or luck that we didn't know about. But just by the nature of the printer that we feel is a nicer building.
Alice Lema: Yeah. So one of the popular interior design item elements right now are those giant they're, sliding doors, but they go into pockets. You see them a lot in Southern California. Maybe you have them in Florida. They're super popular.
Jim Ritter: Yeah. Do, in fact, we're we have designed a 4,500 square foot house on the inter coastal on some property we have, and we haven't started printing yet, but that's in that design. That's [00:25:00] no problem. So that's no problem.
Well that's just a beam design, and then you just print your walls on either side for the width. I think ours is 18 inches. I forget because you, you know, you get multiple doors, we have five doors that slide in there. Right. So, yeah, I think it's two feet. So we have a you know, area where those doors slide into and then so we have that designs that we've been working on.
And of course, because we have 15 foot high ceilings in there, we have Quite a wall design that we're doing the engineering. You do need structural engineers in that because we don't have the library of engineering for 3d printing that we have for conventional.
Alice Lema: Gotcha. So who who, who brings that expertise?
Jim Ritter: Structural engineers. You go to a, oh, you just get a regular structural engineer. Okay. Yeah. They're all they they're savvy. And we have some ideas that we, we give people how to get it through permitting and that, and just like when they started block, I mean, when they started block, they didn't build all [00:26:00] block buildings.
They, they basically built post and beam buildings. We initiated a lot of these methods, so that if you do, what we could do is solid printed walls. If you do that right now, the code hasn't caught up to us.
Alice Lema: I was gonna ask you about that. Yeah. How do you deal with the building department?
Jim Ritter: They're they're no problem. We, we just didn't we just got a building with Miami Dade, electrical building for a large concrete company that we told 'em how to do it. And Miami Dade said yes. And so now they're going into the printing ,you know, the permiting process. Wow.
Alice Lema: So they're, they're approving a 3d building, just kind of, as part of the normal course of the day.
Jim Ritter: Yeah. Because of the we've incorporated conventional with 3d printing. And as 3d printing takes a larger and larger hold, of course, there's gonna be certain aspects of 3d printing that are totally different than conventional, but accepted because there's [00:27:00] enough buildings. There's no 10 year old 3d printed building out there in the world.
Alice Lema: I wonder, what is the oldest, do you think?
Jim Ritter: I think three years, four years.
Alice Lema: Three years. Wow. That's super young.
Jim Ritter: Yep. That's the problem. We're we're still in our infancy and we're not there yet, but it's, it's growing in leaps and bounds and we're gonna be there soon.
Alice Lema: Yeah. So how how long does it take to build a 2000 square foot house?
Jim Ritter: We, we printed property, the exterior interior walls in Tallahassee in six days..
Alice Lema: Six days to 3d print a 2000 square foot house?
Jim Ritter: Well, no, we did it was 1,530 square feet. So we printed that in six days, the interior and exterior walls. And that was, that was the beam was nine feet ceilings.
Alice Lema: Wow. So, so, so many questions when talk about floor plans and insurance, and are you just uploading a digital floor plan? Is that how you get the interior walls? [00:28:00]
Jim Ritter: No, we, we leave that to the individual. They design their houses and we print what they want because the great thing with the printer is we can print a circle, the room we can print. We have freedom design. One thing that we can do that conventionally would be very expensive and we have it in, in, in one of our designs is a curve beam because we print a form for the beam and then all you do is pour it for, to do that. Conventionally is a lot of woodwork. Yeah, very expensive. Yeah. We see 3d printing for luxury houses as very economical right now.
Alice Lema: Yep. Because, well, we've gotta take a quick break. Sorry to interrupt. 3d printing, Jim Ritter founder of Printed Farms will be right back after a word from our sponsors.
Well, hello again, folks. Alice Lema, broker John L. Scott. Welcome back to the real estate show. We're talking to Jim Ritter of Printed Farms out of Wellington, Florida. And during the break, Jim we were talking a little bit about what it was like when you guys came on the scene and the splash [00:29:00] you made with the the other 3d companies.
Jim Ritter: Well, what we, what we did is our intention when we got, we got number five machine produced by Cobo and we've done several things to further the 3d printing industry. One of the things we've done is never bring the machine inside. We've left it outside for two years. Because if it's a building machine and gonna do what everybody claims it has to work 24/7 in all weather.
And we did that. And so far the machine's been very good. But that's only two years and a hope I can say this after five years. So the machine has to take the weather. We were the first people to print outside of a tent or building. We said, that's not economical. So we printed totally outside. And of course had our issues to figure that out.
And the other thing we did is we utilized the machine for what it could do to build a building. And we [00:30:00] incorporated the conventional methods that would be approved by the permitting agencies, into our building design so that the 3d printer could be used to its fullest, which is pouring the slab. We were one of the first people to take the machine and pour the foundation or slab.
So it was square and everything by printing the form, we had the being square and level. Then we poured with the machine. Then we of course printed the walls, which everybody does. And we printed the cavities for the columns and which support the roof. And then we used the machine to pour an ICF system roof, which is a standard conventional system.
And we used that system what we call prints and it came out very well. We didn't know it would, but it did. And you know, we put in the window and the doors and the lintels, we printed the forms for the lintels. We printed the, one of the first tie beams, our tie beams, almost 36 inches [00:31:00] or three feet high.
The building's a bunker to put it mildly. So it is overbuilt, but we were testing a lot of different concepts and we didn't publish it until we were done. We said, okay, now we can publish. Now we can help people to build in a, in a more effective way. And that's how we got into the Tallahassee project, cuz we had one of the most economical, effective ways to print a building. And in Tallahassee, it rained all week and we still got it done. So it was a mess, but you know.
Alice Lema: Well, that's construction. Right, right. Construction's messy. Super cool. So it's, it's using these machines an economical way. Is what has to be done so that we get a greater data and everything else.
So so you're creating the machines.
Jim Ritter: No cobot. We are a distributor for CoBoat, distributor for cobot.
Alice Lema: And where does the, [00:32:00] where do you get the material for the print job?
Jim Ritter: Well right now, we're dealing with several providers. Crete Titan, other s. And we have a local outfit in Orlando that is very creative, that we're testing their system, their material. And we do a lot of material testing to improve the material so we can print faster and higher. When we started printing, we printed at three quarters of an inch. Now we're almost up to an inch and a half, which cut our print time in half. So we trying to build thicker layers, but not wider. There's a two to one ratio and we're trying to shave that.
You have flaps where we can print with a smooth finish. And so we do a lot of testing. We testing the materials so that when we sell it to people, it does what we say it will. And it's the right material for the building. And of course the same for the machines. We work with the machines. We do our [00:33:00] test projects in real project time so that we know what the problems are with the machine. And of course we fix it with the manufacturer so that the machines work better and more effectively.
Alice Lema: So we were talking earlier about different climates. So Southern Oregon is a drier climate. How do the, how do these homes withstand more, less moisture, a lot more heat?
Jim Ritter: Well, that's no problem. They printed in Arizona, which is very dry as you. Using the Cobo system, they printed some habitat for humanity houses there. It's your curing process? The drier the area you're gonna have to put a lot more water as you print on the project. And keep it moist you know, cover it and keep it wet like you would any slab or anything. Heat in the summer or very humid, a lot of rain.
So of course, with our [00:34:00] Tallahassee project, that wasn't an issue because we had too much water as it is. But that's part of cement. You want to cure with a lot of water because you don't want the wetter interior to be drying at a different rate than the exterior. So when you have two different rates of drying, and this is any cement, that's when you'll get cracking.
So we try, you know, that's with 3d printing the same. So you would, would have to have a lot of different systems for keeping the material moist until it cures .
Alice Lema: And then snow country, same thing?
Jim Ritter: Well, the Germans printed in a sleet storm, which was about three to four degrees centigrade.
I am in Florida because I've been in Sweden and I hate it. so you can have the snow. I, I think cold is the biggest challenge to printing. I mean, You obviously, and then again, it's a cement thing. It's not a print thing. You have to be [00:35:00] careful of freezing and everything else. So you have to mitigate, you know, at what temperature you can print in.
Whereas we have the opposite problem where it's very, very hot here. 94 degrees in the middle normal, you know, during the summer and the hoses get very hot. So the material has to be able to take that heat. So every area of cement is tweaked for that climate locally. So it's a localized system, the printer, the material and everything else.
You can't do what we do here in Oregon. We have to change it. We'd have to tweak it well.
Alice Lema: But the beauty is you can.
Jim Ritter: Yeah, well, that's, you know, and every, anybody who's dealt with any cement understands this. This is why you would like cement people around you, because they understand what cement works in your climate, what chemicals, what you need to do.
Alice Lema: Well, this is just so exciting. And we have a housing shortage here as you know, you guys do too for a lot of reasons. [00:36:00] And this is something that a lot of us, small developers, small builders are thinking of bringing on to create housing and also just have more green construction, cuz that's important too.
Jim Ritter: And again, a concrete structure, something that we push down here, especially if you're in a dense area, you have the rooftops that you can utilize for solar panels, but also for a living space. And they're concrete. I mean, you wanna put your spa up there, you can design a spot.
Alice Lema: Oh, that's a great idea.
Jim Ritter: And you see it in the Mediterranean. We didn't invent this, but rooftop gardens are beautiful. You have a better view. Then, and it's so much nicer than a cramped backyard where, you know, they see a six foot wooden fence. Yeah. So we promote a lot of things. There's a lot of things that you can do you know, by doing concrete structures that just make a better living area.
Alice Lema: Well, we're talking to Jim Riter of Printed Farms in Wellington, Florida. He's the founder and [00:37:00] CEO. So Jim, just real quick, how can people get ahold of you?
Jim Ritter: Well, they can go to our website printedfarms.com and there's our phone number and info at printed farms. com you send us an email and we answer it to our best of our ability. And we go from there.
Alice Lema: Well, thank you so much, Jim. I hope you'll come back and give us an update later in the year.
Jim Ritter: All right. Thank you very much for having me.
Have a good day Southern Oregon. See you next week. Bye now.
