Hi -
I have a CAD service for professional goldsmiths and I do own a form 1+ and a robox fdm printer. I use the form1 for prototyping jewelry and for that it’s really good. For casting it’s not really usable for fine jewelry or let’s say: it just does not make sense. The quality is not really that good compared to what’s already out there, it takes a lot of time to print, finish and get ready for casting and then the goldsmith has more work with polishing as the surface is not as good as with wax. Pricewise you will have a real issue with the competition like shapeways etc or even the regular casting houses that offer prints made in a milling machine or with a solidscape. The problem as well will be the consistency of the prints and reliability of the printer. You will encounter a lot of problems with the machine… with all 3D printers really. So you will have a lots of times when your printer will be out of commission due to repairs. No plug and play as the say :-). The fdm printer is not usable at all for fine jewelry. Look, I love my printers, would hate to be without them. There is nothing more fascinating than watching something get actually build in a machine that you just created on your computer! But it’s more of a passion than a wise business decision.
Good luck
Julia
