The mission of the Nuclear and Particle Physics (NPP) Directorate of Brookhaven National Laboratory is to provide state-of-the-art experimental user facilities for nuclear and high-energy physics research and to conduct world leading research in high-energy nuclear and particle physics. With an Ultimaker 3D printer and Ultimaker ABS you can print in 10 colors, with the ability to create dual-color prints. PLA is classified as a thermoplastic polyester (as opposed to thermoset), and the name has to do with the way the plastic responds to heat. Biologisch abbaubare Kunststoffe knnen in vielen alltglichen und speziellen Bereichen eingesetzt werden. This ease of melting also makes polylactic acid suitable for 3D printing applications.
