3D printer manufacturer Leapfrog, known for its Creatr line of 3D printers, introduced its latest desktop 3D printer, the Leapfrog Bolt, just a few months ago. The Bolt has a built-in camera, an activated HEPA carbon filter, and thanks to its set of dual extruders, features multi-color and multi-material 3D printing. Now, the Bolt can add a new material to its wheelhouse - it has successfully 3D printed using plastic polypropylene (PP) filament, provided by materials and filaments expert Verbatim, the subsidiary for Mitsubishi Chemical Holdings Group. PP has a large variety of consumer and industrial applications, with high chemical resistance and mechanical properties, and is one of the most used plastics in the world. Unfortunately, it's difficult to control the results of 3D printing with the material, because PP undergoes a lot of heavy warping during the process: it's a semi-crystalline material, which means that it cools and solidifies differently than amorphous polymers like ABS and PLA.
