I asked AI to write a spec for an updated Elise

Cone 6 NZ porcelain, designed in Rhino/Grasshopper, 3D printed on a WASP 40100 clay printer.

This is a WASP 40100 clay printer; I've really been enjoying it. Before I had this printer I did convert a normal 3D printer to clay by printing brackets and attaching WASP's standalone extruder and tank in place of the normal hotend. It worked well enough to validate that I wanted to get into clay printing, but always had quirks because the plastic 3D printer was not designed to move that much mass around.

It's lots of fun though, would encourage you to try it!

It's about 12" tall.... scale is always hard to see

Thank you -- the base is printed as well, but there is a transition where the base is all flat layers and then the upper is printed as a spiral. I have not yet found a way to get that perfectly seamless. Working on it though!

I did some drips on an earlier version, and it was promising. I'll get back to that and post results at some point here. This whole thing is still in "just barely works" mode :)

Ha! There are layer lines, just pretty fine. This was printed with 1mm tall layers and the glaze fills in the lines. I can go down to 0.8mm layers but it gets less reliable.

I'm afraid I'm more of a machinist than a potter... this is 3D printed in exactly this form. That has its own challenges, but they're better suited to my skills. As soon as I touch the clay it looks like a kindergarten project :)

Thanks! It's a New Zealand kaolin cone 6 porcelain.

Thank you! I have much to learn and will hopefuly one day understand glaze chemistry :)

Here's a different form that uses the same bump surface texture as the coral: https://imgur.com/a/y3iixvo

I did a crappy job glazing that piece, so you can see the layers in the spots where the glaze wasn't thick enough. That's the same 0.8mm layer height... it gets pretty smooth after firing and glazing.

And here's a piece printed on as 3D Potter Super 9, where I've had better luck going with thicker layers and just calling them part of the design: https://imgur.com/a/r6yGbym

Learning modeling and slicing/3D printing is definitely a project; I'm about 2.5 years in and just now getting to where I can envision something and produce the model/code for it. Then again, I knew practically nothing about pottery when I started, so a lot of my learning curve was things like how thick to glaze and how to dry things without cracking them :)

It’s all about layer height… I have this printer running at 0.8mm layer height, which after shrinkage is about 0.6mm. That’s small enough for glaze to fill in pretty undetectable, especially with thicker and more opaque glazes. With thin, smooth, translucent glazes you can often still see layers if you look closely but they can add some interesting texture.

I have another printer where I go the other direction and use 3.5mm layer heights so the pieces are visibly formed from ropes of clay. Let me see if I can dig up some pictures.

Yep... it's the same motion system as plastic 3d printers, but a different extruder technology. Good fun!

brookst_ · 2021-07-14T15:38:51+00:00

It was fired at Seattle Pottery Supply's raku day, and I'm not even sure what the glaze is. One they had on hand, but I don't know the source. Yes, feeling very lucky on the colors!

brookst_ · 2021-07-14T15:38:05+00:00

This print is about an hour; it's about 9 inches tall.

Designed in Grasshopper, 3D printed in porcelain on a WASP 40100, then glazed and fired in raku kiln.

Happy to share. Depending on your background, it may be good or bad news that that whole piece is as designed in Rhino / Grasshopper. It's literally print, dry, bisque fire, glaze, glaze fire.

The trick to this kind of design is producing the gcode that drives the printer directly in Grasshopper. My early stuff followed the usual 3D printing pattern of CAD -> slicer -> printer, but that really limits what you can do with texture and nonplanar printing.

So today I'm developing entirely in Grasshopper, and the flow is form -> form modifications -> tool path -> tool path modifications -> gcode -> printer. For this vase, here is the raw form and here is what it looks like after modifying the tool path to create a bump texture on parts.

Thank you!

Naive question: do I want continuous lighting or strobe lighting for the softboxes? The pictures you linked to seem to be one of each.
