KMM Posted August 20, 2015 Report Share Posted August 20, 2015 Hi All I’m new to Ceramics. Would like to tap in to your collective knowledge. Thing is that I’ve developed a light that I would like to make with Bone China. The light has fine details that I suspect won’t work out doing with injection moulding or slip casting. I’m actually thinking about casting a block of bone china and the putting it through a CNC machine, after putting it to the furnace of corse. My question is would that process work on bone china? Wondering if the material is to fragile for this process. Please share your thoughts. Thank you Link to comment Share on other sites More sharing options...
Mug Posted August 20, 2015 Report Share Posted August 20, 2015 If you can post a sketch of what your are trying to do, someone on the forum could help. While what you are suggesting may be possible by some large stretch of the imagination, it would certainly, if possible, not be cost effective.

neilestrick Posted August 20, 2015 Report Share Posted August 20, 2015 Getting a block of bone china to dry without cracking would take weeks. Firing a block without issues would take days, if not weeks, in the kiln, but I doubt that it would work even then. I don't think a CNC machine could efficiently carve a block of bone china. It's just too hard. You best bet is to use traditional ceramic processes such as slip casting. If you don't know how to do that, I recommend taking a class.

ShellS Posted August 20, 2015 Report Share Posted August 20, 2015 IF you could get the block of bone china , not sure how ... it could be possible but not feasible due to time & cost. You will need Diamond bits ... Spindle speed multiplier to 30,000 rps just for starters & would be a very long expensive process Link to comment Share on other sites More sharing options...
Mark C. Posted August 21, 2015 Report Share Posted August 21, 2015 Wrong process-wrong material for CNC work-cnc great on wood and metals. Try another process with bone china like slip or ram press. Mark Link to comment Share on other sites More sharing options...
TJR Posted August 21, 2015 Report Share Posted August 21, 2015 Mark is right. You are asking the material to do something that it is not meant to do. Look into slip casting from a mold. TJR. Link to comment Share on other sites More sharing options...
High Bridge Pottery Posted August 21, 2015 Report Share Posted August 21, 2015 There are a few printing options out there for ceramics being developed. Link to comment Share on other sites More sharing options...
jolieo Posted August 21, 2015 Report Share Posted August 21, 2015 Wow! That is interesting! So just idly wondering , if the printer is depositing ceramic or clay line by line, why couldn't it deposit glaze right where it needs to be,and that would be self glazing too? Also if they used something for the packing powder that burned away clean, they could put the whole brick in , fire it up to cone 10 and be done w it? I want one!

High Bridge Pottery Posted August 21, 2015 Report Share Posted August 21, 2015 The powder around the item is the same stuff as the vessel. They put down a layer and then print some kind of glue over the parts the want to stick together. At least I think that is the simple way to think about it.

jolieo Posted August 21, 2015 Report Share Posted August 21, 2015 Aw! So I would technically need thre different printer feeds working in tandem. Still , what fun. Link to comment Share on other sites More sharing options...
jolieo Posted August 21, 2015 Report Share Posted August 21, 2015 They will come up will multiple feeder heads at once, mixed media and then the real fun begins. Could a laser bring ceramics up to temp on a microscopic level? Link to comment Share on other sites More sharing options...
Jeff Longtin Posted September 22, 2015 Report Share Posted September 22, 2015 John Ballesteri(?) a professor in Idaho, developed a clay formula for ceramic 3D printers. (The printer lays down the slip and then the piece is fired as normal.) A professor at Harvard(?) developed a printer that prints molten glass and fires it as the printer head moves along.
