We 3d printed 3 different parts of the fire pit and then made silicone molds of the prints. We used Quikrete 5000 concrete mix in the silicone molds to make the final blocks for the Firepit.

HomeMadeModern simply beautiful truly love the design have you thought of selling the molds for this project?
Deceptive Title
Yoooo such a high infill percentage for such a big thing that print must have taken like days
I really like seeing how you can use 3D printing with other techniques to seriously up your game!
Awesome! There is brilliance in the simplicity of this design. The look brings to mind “Sacred Geometry “, the elegance of natural patterns. This is beautiful.
Yes! I was thinking geometric petals!
Outstanding! I love seeing 3D printing projects that are "useful"..
Awesome idea! Love the notion that the smaller blocks dissipate the heat quicker. Top stuff!
That is a very sharp looking fire pit. Thanks for sharing!
Such a cool look! I like the simplicity of the design process and the very complex look of the finished product. 👍
FYI if anyone chooses to follow this guide and 3D print the positives for the molds.
1. Drop layer height to increase quality of part.
2. Parts show here were printed on close to 20% infill which uses excessive material and time. Since they don't need to be strong they could be printed on closer to 10% infill.
3. PLA can be sanded down to remove ridges although you would still need to fill the gaps with Bondo if printing in multiple pieces.
at first i was like "that's too much work" and then it turned out the pieces were one-time made to be molds, that makes much more sense
Wonderful project! I will be making one! Thank you for sharing the files!
this turned out absolutely amazing! love it!
Unique concept. I like how you modeled them to be different pieces, but then fit back together. When you first take a look at them, they don't seem like only 3 variations...it seems like many more!
Beautiful design, they would also make a great flower bed.
Wow I could look at that pattern all day! Great video!
Super cool looking firepit!
Very clever!! The end result is awesome!
That's gorgeous.
It looks beautiful!
awesome, love this. Just put 3D printer on order this morning.
Brilliant! Silicone molds and quick concrete! Great combo along with the 3d printer!
yes! its one of our favorite combos
Lol. So. Much. Infill! :). Love the look of the final pit!
Can we talk about Ben's knife!?! Gotta be ready for anything out in the desert! Great video as always!
Love the aesthetics
Great design!
Wow, looks fresh
I love the finished product! It's such a neat design and it's a versatile enough idea that you could rearrange the shapes or add a couple of new ones and end up with a totally different design if you got tired of this one. And it's great that you used 3D printing and concrete to get there! I could definitely see making the original forms out of wood if one didn't have a 3D printer. Neat!
Beautiful design!
Thank you!
this is beautiful :-) it's so aesthetically pleasing!
So beautiful
Very cool project, love it.
Simply amazing 😊
Love it. Very nice!
That's awesome! Sudden am envisioning a more useful purpose for my printer. I really liked that design. Really had a great feeling of urban and woods coming together.
I totally agree. I think there are some really cool fractal patterns that could seem both futuristic and natural
Awesome result, and begrudgingly I have to admit I can get behind the use of Quikrete for this one :) It came it so smooth -- there is no reason to use anything more expensive.
So great!
That's pretty cool.
I have never seen a fire pit like that before cool
I was really waiting for you to mention the Rambo knife!!
Those silicone moulds look soo great. I need to get moulding :)
A month into 4mins video awesome
Amazing
What purpose do those concrete pieces serve? Seems to me the fire would be just fine without them
Fantastic... Excellent 💖 💖 💖 💖
I'm a bit curious. You're essentially using just the outside of the 3D printed shapes to make your silicone mould. Why did you print them as thickly outlined and skeleton infilled shapes instead of using just a thinner outer shell? Are they not strong enough with a thinner shell? Did they warp too much when using just a shell?
Genius
Such a great idea I was just wondering if the mold could be made with wood shapes and then realised that means the options are endless!!
I tought you were going to print all the stones😂
You could definitely print all the stones, but I think it's cool to showcase the silicone mold aspect of creating products in a small scale production rather than 3D printing each piece.
It's called clickbait, they do it on purpose sadly.
Hi Miguel, out of curiosity what would you have titled this video? We try to be as direct as possible while keeping the titles short and then explaining a bit more in the description. We considered calling it Concrete Firepit cast in 3D printed forms but that was so long and still is not 100% accurate. If we left out the 3d printed part of the title people would complain that we showed them a build that involved digital fabrication. In general putting 3d printing in a title results in fewer views on our channel so there was no clickbait motivation there.
HomeMadeModern in my opinion its a brilliant and smart title. It contains, like what you said, all the elements of the video. Maybe a bit misleading but that is what makes the video attractive to click on. Its sertainly not the 'clickbait' level that other titles are....keep up the good work! Greetings from the Netherlands!
Maybe I jumped to a conclusion there so apologies if I did. But it mostly came from the fact that it seems like using "3d printed" in the title is forced since the final product is not 3d printed. I didn't pay attention to the sponsor so I guess it makes more sense now. Cheers, love the content.
Lit AF :P
Looks great, when it is perfectly aligned... Somehow I don't think it would stay this way for very long, and after a week it would just be a bunch of interestingly shaped stones on the ground.
we will probably set them in packed sand once the new property is ready
If you’re making a silicon mold why would you make the infill so high?
Just in case someone wants to create the forms without a 3d printer: Choosing XPS foam over wood might save some sanding time. :-)
good suggestion!
This project is 🔥🔥🔥!
thanks!
Hi Ben, thanks for the video and the designs, your work is gorgeous. What material is best to print the 3D objects used for the silicone mold? I'm sure there are differences in finish despite the Bondo being added
Roughly, what volume of silicone was used?
That’s pretty dang cool. Kind of disappointed you didn’t actually 3D print concrete with a special printer, but still cool none the less.
Some other idea would be to add color flakes and other small stones into the cement before pouring to get some cool patterns.
I would like to see more of the 3D printer.
I've been waiting for this video since the leaked Instagram pics.
thought you were just gonna toss the pla parts next to the fire and call it a day. Glad to see that wasn't the case. cool video, would love to do it at my cottage but im sure some stones would go missing.
When I first read the title I thought you somehow used concrete mix in your 3d printer. 😁
I really like the design of the blocks and the final pattern that the blocks make! 😍
How does this provide any fire-spreading protection?
Do you have the large diamond shape separated into two files? It's too big to fit on my Robo 3D R2. Thanks.
That’s bad ass
great idea. this concept could be used in other way, maybe wall tiles etc :)
You could easily reduce infill to ~10% or less and it would print considerably faster. But that's just my 3d printing geek inside, gread project!
cool project!
love your videos, they're really inspirational!
This is a very nice design. I was wondering if there is a way to skip the molding process and go directly from the 3d print to the concrete form. While I have not been working a lot with flexible filament it might actually work out to create a mold from flex filament and directly pour the concrete in it ...
I'm pretty sure we could even pour concrete in solid material like PLA as soon as the design is simple and the mold is well thinked. A design like this one could be printed as a four interlocking parts mold for each pieces. I actually have to try this!
BTW @WayofWood love your channel, love the way you use your printed pieces as tools and not as finished product.
I'd recommend ninjaflex 👍
tokagehideto well thinked 😂
@Emmett Martin , sorry if i sound stupid, english is not my native language and I sometimes do big mistakes.
The amount of material required would be ridiculous, and there's a good chance that the layers would separate.
That was beautiful, dude. I almost cried. jk, but you earned my sub.
Coolio
On each video, you should put how much you spent on the materials
really modern look for the oldest practice
Interesting design process. I think it would be faster to just make the prototype shapes out of cardboard or foam core. Then you could fill them with plaster of paris and proceed from there. You don't even need a computer to draw these shapes. Just a compass, ruler, and a bit of math.
yes! foam or wood would both work well!
For a second there I thought you were going to make a plastic fire pit and was slightly concerned for your well being
Can someone tell me where I can get one of those glue guns?
How expensive are the pair of Mold-Star 30 buckets?
Great design process and love the final product. I hate to mention that concrete will easily crack with the heat generated from fire. This project is probably only as useful for very small fires that are within 2 feet of the blocks. Otherwise its way cool!
large pieces of concrete will crack because of trapped moisture. I have experimented with small pieces like this and have had zero cracking. the surface to volume ratio of the shape also impacts the cracking.
Could always go for some refractory cement if you were really worried.
Troye Stonich you didn’t watch the video before commenting did you.
Why not just 3d print them out from metal, Or you could weld them quite easily after punching them into shape.. The one block (if made out of ss 304) is only going to cost around 10USD welded.
That way you'll have a commercial grade product that can be shipped and sold globally.
Mind you this would make a good wall decor (flatter)
Nathan ObJective because metal 3D printers cost 100k+
Anybody know of a more affordable silicone for the mold? My Canadian distributor for Mold Star 30 says it's $250 plus shipping for 1 gallon of it. Way too much.
3d print or fabricate the mold out of plywood. Just take the negative of the shape. Maybe cut the model in half or quarters, and make indexing pins and holes for bolts. This makes getting the casting out easier. Use petroleum jelly as a release agent. Don't get why they didn't do this in the first place.
Is there a reason you chose bondo over acetone for smoothing?
acetone doesn't dissolve or smooth pla plastic. 0:42 top right of cura settings
why don't you cast in a 3d printed mold??
Very cool looking! Do you think a vacuum form could be used aswell or for the casting forms?
Thank you! Yes it could, but keep in mind that vacuum for molds will not last as long as silicone molds.
yes! I am currently researching vacuum forming.
Thanks! I've been thinking about building a vacuum former and this would be a great use case.
I can pretty much promise you that a thick vacuum molded concrete mold would last far longer than a silicone concrete mold. Silicone gets torn up over time from the concrete. Vacuum formed would be much more solid.
Great video. Love the idea. Was there a reason you used Bondo instead of spray on filler primer?
I haven't tried a spray on filler yet but open to the idea. know of a good one?
I use Rust-Oleum 2-in-1 Filler Primer. It's worked for me on a number of projects. I recommend applying a coat, letting it dry, sand and repeat until smooth. It usually takes me 2 coats to smooth out a 3D print.
could I buy the mold from you?
AN ABSTRACTION IN SEARCH OF EXTANT MATERIALS...
I've never seen a hot glue gun that looks closer to an electric screwdriver than to a hot glue gun
What was your fill percentage?
Now what you gotta do is bring it to grade with some sand and plant moss in the cracks.
How expensive is that silicone? Looks by far the most expensive part of the process.
if you made a vapor chamber and put your prints in there it will smooth out your print.
Won't work for PLA which is what he said he used. ;)
Worlds most expensive fire place
will you just sell the molds?
Why didn't you just print a (segmented) mold????
your wife is not going to be happy.. that you used the salad bowl to mix that stuff. lol
There’s this thing called rocks
How long does all that cad drawing take?
Hi Mike! Jamie here. The 3D modeling (assuming that is what you mean by cad drawings) took me only a couple hours. The most time consuming part was getting the dimensions right on Illustrator.
did you separate the melamine from the mold using a RANDALL KNIFE!? a travesty!
How much did all that silicone cost?? 😟
about $140
That's pretty badass. But, I'd find a way to screw that up in quick order. Contractors exist because of idiots like me.
Ii'm not sure if you needed to print the masters THAT thick....
actually thought you were going to 3d print the concrete
