It uses a voxel system to create shapes, which is super neat. It bypasses a lot of potential problems with meshes.
Beekey, a software engineer at Shapeways, demo-ed a lot of cool apps you could make with ShapeJS, like the 2D to 3D converter. I’ve used the converter, and it’s been really helpful. Previously, I’d import my 2D vectors as surfaces in Maya, and then extrude. Now, it’s a super easy, one-click process.
Beekey said they haven’t super stressed tested ShapeJS. I’ve definitely crashed Shapeways’ mesh fixer (Mesh Doctor / Netfabb) before, so I hope it holds up.
As from ShapeJS, I learned a lot about powder-based SLS from Beekey. However, I was shocked to discover he’s never heard of MAKE!
C’mon Shapeways engineer, gotta get with it! 😛
