Dandy Lab - 3D Dentures

[kenn]

what printers have you used to make digital dentures, and what are your likes/dislikes for each?

Personal usage is limited to Carbon, Asiga, and Formlabs. I've evaluated samples from the likes of HeyGears, NextDent, Stratasys J5, etc etc.

I don't think I have particularly new/novel opinions on the printers themselves that you haven't heard before:

• Carbon consistently produces great results without really thinking about it. Everything just works.
• Asiga can produce similar results to the Carbon, but with far more maintenance and baby sitting. There are also a handful of under-the-hood tradeoffs they make that Carbon doesn't. Also find Composer clunky to use, especially in a production setting.
• Formlabs SW (Preform) product is better than Composer, but not in the same ballpark as the others when it comes to HW. I suspect a lot of that will change as the Form 4 matures.

WRT Digital Dentures, it's so far been the story of Lucitone. I'm going to butcher the exact science behind this, but Carbon's projector does far more upfront "curing" than other printers. This drives better overall part strength, and relies less on post-curing (which obvs is heavily impacted by part thickness/mass).
