Hey guys, I printed and cast these little rubber chickens to make pendants for a friend’s glass studio, and something amazing happened. Keep in mind that they are about 1-1/4" long, so pretty small.
It wasn’t until my friend posted a photo on Facebook of the chicken I gave him, and I realized that the Form 2 had printed detail that I couldn’t see with the naked eye! I had given the chicken a textured skin, and even a tongue and a uvula (that thing hanging down in the back of your throat). Those details showed up! He was designed in ZBrush (the full version, but it could also be done in ZBrush Core).
By the way, I’ve found that raised designs like the logo work best when they are at least 0.3-0.4mm raised off the surface.
I also printed a larger one that maxed out the size on my Formlabs…I found “slush rubber” online and will use the model to make a mold that I can cast an actual rubber chicken!
Oh Form 2, where have you been all my life?
(For anyone interested in the details…this was cast with BlueCast in open mode on Gray V2 settings at 0.50 microns, although I also use the Formlabs Castable V2 resin. It was cast on a Kaya Cast vacuum setup with Plasticast without Bandust (Formlabs recommends with Bandust, so mine is different), ramped as normal with max temperature 1375°F for three hours, final temp 975°F, metal temperature 1855°F in a Kerr ElectroMelt crucible. The burnout is about 12 hours, but I’ll be making an RTV mold out of the Formlabs Castable V2 model and using wax for the rest).
