3D Prints - in Space

Another pioneering effort by NASA: a 3D printer has been installed and placed into operation aboard the International Space Station. The first object to be printed is a face plate for the 3D printer extruder. Great to keep up with the company, Made In Space, their activity (and more pics) on their blog. The zero-gravity printer uses ABS plastic, but a second generation printer, planned for delivery in 2015, will use other types of materials. Their stated plan is to print tools and parts, as well as 3D designs submitted by students, with the goal of establishing a manufacturing capability in space.

Pixar's Tony DeRose Explains 3D Surfaces

An amazing explanation by one of the brainiacs at Pixar's Research group: how to mathematically determine a method for making smooth 3D surfaces. So while you're yelling at your screen because SketchUp is making you nuts, remember: at least you don't have to do the math.
