Re: large dlp printer

With the way that light engine moves, they have to really get their accuracy down or else you'd have pixel shifts across each band. Very impressive if they can do it. A interview video from Rapid 2015 on Youtube mentioned they are only targeting the manufacturing space, so nothing at 'entry level' o...

Do you soak and swirl or do you use an ultrasonic? I'd think the ultrasonic would help get the uncured resin out from all that detail.

Re: question about casting, not solus related.

Depends on how big of a flask you intend to cast, but I use an electric Paragon SC3 kiln for my small (3.5" tall and shorter) casting. It has a pretty good controller to program different multi-stage burn out cycles. I keep mine on an AV cart because you don't really want it sitting on a deskto...

Were all the supports for that spoon done with Creation Workshop, or another tool?

Great detail! What are the other dimensions of the spoon?
