We bisque fired everything at 1000°C and all tests came out of the kiln perfectly which is very encouraging. Air doesn't seem to be to much of a worry. Yes, those are Utah teapots :)
Laszlo, thats definitely on the list. Good test to see how we could do overhangs. Some Reprappers want to use a syringe design for support material, maybe we should do the opposite? Use ABS as support?
Just phenomenal! Firing 3D printed clay is an unexpected and significant innovation.
Did the double-walled bowl shrink in the firing in its gross dimensions? Also wondering if you would anticipate problems with sanding and glazing the dried clay befoer firing.
BTW my first impression of the kiln shot was "what a nice rendering"!
Hey, just got pointed to this blog by Enrique. I don't know if you've explored the use of fireclay (or ordinary clay with graphite added to make it refractory). Refractory clay is used to make crucibles for metal casting, and will not explode at high heat, or so I've heard.
For a moment I believed, that the utah teapots are printed on the machine too.
ReplyDeleteNice progress by the way.

ReplyDeleteWow, great work.
ReplyDeleteDo you think it would be possible to infill the double walled bowl with slip at this stage and then re-fire it to create solid components ??
There are advantages to this. Attempting to print more solid components in one go may be time consuming and likely to entrain air. (Bad)
Or should I say:-
ReplyDeleteDit is en uitstekend oplossing
Goed gezegd :)
ReplyDeleteNo, the shrinkage will be different but you could do it pre-bisquefiring when the greenware is air dry I guess
Fantastish!
ReplyDeleteI know of a composite ceramic that would be great to eliminate the need of firing. Would this be of interest to you?

ReplyDeleteAlways! Although fire is cool...
