EOS Selective Laser Sintering is the 3D printer technology behind our White, Strong & Flexible machines. EOS gave us a the cutest little gift last time we visited them, a tiny working Christmas bell. The sound is not perfect yet but the idea is a great one. For some reason I never even considered that you could make sound with 3D printed things. Duh! Amazingly, just a few days ago YouKnowWho4Eva uploaded a Co-Creator Christmas Bell meant to be 3D printed in Stainless Steel that you can personalize.
