Building Large(r) Format Printer For Ceramics
Posted: Wed Jan 20, 2021 9:57 pm
So I have a been entertaining the idea of building a 3D printer exclusively for ceramics as I have my own kiln. You may be familiar with the paste extrusion SCARA based machines sold by 3DPotter and some of the similar Open Source paste extrusion products, but to me dealing with powder sounds substantially easier than getting tubes filled with slip/slurry of an exact consistency and completely void of air. Not to mention self support limitations of paste, extruder mass when loaded with sufficient clay for large parts, etc.
Anyway, I'd like to build something based on your Oasis system with the largest deviation being build volume and an emphasis on build speed over maximum accuracy. We are talking mugs, vases, sculptures etc nothing intricate like small lattices or figurines. Initially I would like to aim for a build area around 100mm^3 (cubic or cylindrical) but with the ability to go with detachable feed canisters to allow for a 200mm or even 300m swap out. The way my brain works I'm much better working on software when I have hardware in hand to put it on so hoping you could help me make sure I'm on the right path before I leap in feet first building the hardware.
I noticed the build log says there is room for 5 print heads, were you intending this for parallel production or staggered to increase the swath size? Is there much room to expand on layer height before the print head has to slow down in order to dispense enough fluid making? Do you have some typical layer height and axis speeds I can use to estimate print times? Any general words of wisdom for someone headed in this direction appreciated.
For applications like this I was also curious if you had ever heard of anyone using a single "jet" with the typical profile printing of FDM, Something like a tiny mist emitter or scooter fuel injector? Just a shower thought I had hah.
Thanks,
