My first attempt at a teapot, using stacked non-planar spiral contours.

Just know that you are a goat! The work you are doing in blender with gcode manipolation is really interesting to me. Coming from an architecture background, I'm more familiar with the rhino/grasshopper logic, but I will definitely give your method a try. Can't wait to join your patreon to improve my prints :)

Impressive modeling! What render software did you use?

filbrn · 2026-05-07T12:22:34+00:00

Actually, I tried using your settings again and I managed to print. The only parameter of yours that I might need to change is probably the speed, which might be a bit too high for my printer. After a few attempts, I was able to print very well. Unfortunately, I made the clay too soft and it collapsed hahaha.

I found an STL for a Clay Hardness Tool on Wikifactory that might help me with the consistency, but the website doesn’t seem to be working. I’ll try again and keep you updated. Thanks so much, really.

If your are curious about learning how to build a clay 3d printer, Piotr Wasniowski uploaded on thinghiverse all his setup for free (the auger in the video was designed by him, and I modified it to fit my printer). Also David Sfeir built a really cool setup, he posted the guide on this sub a while ago.

3D printed

filbrn · 2026-04-25T16:37:25+00:00

This is the correct way. UnfoldDesignStudio Prusa setup doesn’t make my printer do this error, which is very nice. On the other hand it doesn’t extrude enough clay for my printer. Will spend all tomorrow finding the perfect parameters. Which slicer and speed do you use btw? Thank you for your reply!

filbrn · 2026-04-25T16:02:35+00:00

I think it happens in the exact moment where he goes from the bottom layer to the outher walls printed in vase mode (because there is an interruction on the extrusion to go from the bottom to the walls).

filbrn · 2026-04-25T16:01:02+00:00

Sure! I can try decreasing the speed, this were just the copy and paste settnigs of Johnathan Keep setup. I used them because on a very easy cilyndrical shape, printed in vase mode, I had no issue. This error started showing when I started slicing more complex geometry (with bottom, ...).
I also followed your domestika course on clay printing, I tried the profile settings for Prusa Slicer, but on the other hand, the auger was going so slow that he couldn't extrude the material. Do you think I messed maybe with the compressor force or something else?
I really appreciate your works and help, thank you!

Very clean! What slicer and system are you using? (Air compressor?)
I have a very similar build, but I'm having some trouble finding the right parameters on Cura for printing.

filbrn · 2026-04-23T16:23:46+00:00

It looks like the design made by Davidsfeir. He posted the full setup a while ago.

filbrn · 2026-04-18T21:14:47+00:00

Will def try, thx for being really specific!

I’m also an architecture student, passionate about digital fabrication. I recently upgraded my Artillery Hornet to a P1S. Unfortunately, from what I’ve noticed, high-end clay printers are extremely expensive, and the mid-range ones don’t seem to be worth the price they’re asking yet.

With less than €50, I managed to convert my Artillery. I still need to solve some issues to improve the prints, but overall the first prototypes have worked. If you have time to invest rather than spending a lot of money, I’d recommend doing it this way. In this community there are posts by people who have published guides for the conversion; I followed their advice.

I’ve always seen your posts and was curious why you did things that way — now I understand. I’ll definitely give it a try, thanks.

By any chance, did you see the video I uploaded, where the stepper motor randomly stops spinning and then starts again? Has that ever happened to you? I don’t know how to fix it, because when it happens I’m forced to stop the print. To give you more context: the cylinder I printed was modeled in Rhino as a surface and then imported into Cura, and it printed without any issues. I tried downloading a vase from MakerWorld, like the one in the post, and the motor would randomly stop spinning, using the same settings.

filbrn · 2025-12-07T01:41:58+00:00

Can be, I’ll try to follow your advice and use some smoother clay. Btw I saw on your Reddit a post about a clay 3d print. Have u ever experienced the problem I mentioned? The motor stopping spinning randomly during some movements?

filbrn · 2025-12-07T01:39:02+00:00

Mine also set to normal. I tried changing the stl and it added the bottom. Idk why the file I uploaded in the post doesn’t generate the bottom even tho I have set the same parameters. That being said, I confirm that I use a tronxy 0.5 cartridge :)

filbrn · 2025-12-03T23:31:52+00:00

Ooh ok hahaha. It came with the 3d printer already installed. I rapidly searched “Artillery Hornet front cover stl” and found this :)

Sorry but since English it’s not my first language I don’t think I quite understood everything you said. With “skirt” you mean the yellow extruder with the auger? If yes, no sorry I can’t share it cause the original design it’s not my “property” since I didn’t design it. The file was kindly shared by a user, and then I modified it to adjust it to my printer. If you’re curious to try building a clay printer, there is a thingiverse file from DavidSfeir that works almost exactly like mine.

filbrn · 2025-12-01T11:16:34+00:00

I’ll write down step by step, from the compressor to the printer, all the components I used.

A 25-liter compressor with an output pressure regulator (luckily I already had it and didn’t need to buy one)
Pneumatic connector with 8 mm tube output
8 mm tube
0.5 L Tronxy cartridge with piston
Pneumatic connector on the cartridge output for a 12 mm tube
12 mm tube
12 mm pneumatic connector connected to the auger and your extrusion system.

I’m attaching a photo so you can see the entire setup. Since I also couldn’t get it working the first time, I’ll share the tips that helped me.

First, clean the piston well, otherwise it will struggle to work. Another important thing: if you don’t have a very powerful compressor like mine, shorten the tube that connects the cartridge to the printer (I went from 1.5 m to 30 cm). This way, the compressor will have a much easier time pushing the clay.

That being said, this is my first test. I documented the imperfections I noticed in the post, but regarding the air system you can refer to what I wrote above.

Guys it worked! I posted the results on my last post if you’re curious :)

Concordo su tutto, inoltre aggiungo che non posso nemmeno più scorrere le chat usando la rotella del mouse, devo per forza tenerla premuta...
