"Anti-Gravity" 3D Printer Sculpts Shapes On Any Surface 51
kkleiner writes "A 3D printing technique has been developed that prints objects that seemingly defy gravity. Dubbed the Mataerial 3D printing system, a robotic arm can print 3D curves on floors, walls, and ceilings, whether the surface is smooth or uneven. Custom-shaped objects are created using a thermoplast that dries on contact with air, which offers an alternative fabrication method to typical 2D layering printing approaches. Though its broad practicality is questioned outside artistic creations, the video produced by the team is mesmerizing."

You really think that a metal panel (hell, the body of a vehicle) would be "just as strong as before" if replaced with thermoplastic? Or do you suggest that the body of a vehicle can be reduced to the bumper?
What makes you think the use of 3D printing will make your car repair less expensive?

The fact that they simultaneously claim it is a thermoplastic and that it cures confuses me.
Thermoplastics don't really cure, they just melt and "freeze", so what is it?
