Does anyone use/know of a method to make very small joints for a ball and socket armature?  I'm talking about knee joints in particular, so they can actually be hinge joints if that makes it any…Continue

Narrow Joints

Does anyone use/know of a method to make very small joints for a ball and socket armature?  I'm talking about knee joints in particular, so they can actually be hinge joints if that makes it any easier.  Most of what I see (aside from feature film armatures) are tremendously bulky.  I'm fairly inexperienced with ball and socket, so if it seems unlikely that I'm going to be able to pull it off, please let me know.I would need these joints to be significantly narrower than 1cm.Now that I'm…See More

Wholesale Jewelry Supply for Armatures

I've been trying to find a good way to get parts for a ball and socket armature I'm constructing.  Over at stopmotionstore.com (animateclay), I saw that they were selling all of these different lengths and diameters of pre-threaded rods and balls.  Unfortunately, mostly everything is sold out.  I eventually found a video explaining that they had purchased a lot of barbells usually used for jewelry.Does anyone have any good leads on similar supplies online?  I'm having trouble finding suppliers…See More

Has anyone cast from polyamide 3d prints?

Started by Joshua Liebling in CASTING. Last reply by Joshua Liebling on Thursday. 2 Replies

Polyamide plastic will apparently break down with water exposure, so this rules out gypsum molds. I'm curious if anyone here knows whether two-part silicone putty or other material would work with polyamide? I know this can be done with PLA. My end…Continue
