This Machine Creates 3D Objects in Seconds Photo: Myyart When we think of 3D printing we usually think of a little robot that squirts out endless lines of plastic onto a surface. But vacuum forming—smoothing a sheet of thin plastic over an object to make a hollow copy—has been around much longer and is the premise behind Myyard’s Formart 2. Advertisement The machine allows you to place an object on the print bed and make a perfect copy in minutes. To use it you place a flat sheet of plastic onto the holder which the machine heats to just below its melting point. The system pushes the plastic over the object and a pump sucks out the air, forming a 3D model that you can then cut out, use as a mold, or just assemble as you would a hollow plastic toy.
