ESA-supported start<\/a>up TIWARI Scientific Instruments in Germany has developed low-cost 3D printer, the RAPTOR, which is capable of 3D printing<\/a> a variety of metals and ceramics using a bound powder filament extrusion process. While the 3D printer is similar to other systems now available in the market \u2013 such as those introduced by Nanoe and Triditive among others \u2013 TIWARI was able to leverage support from ESA to validate four metal and ceramic materials for space and other application<\/a>s.<\/p>\n

TIWARI\u2019s process uses thermoplastic filaments that are embedded with part<\/a>icles of the metal or ceramic the part<\/a> is to be made from. Once the printing is finished, the green part<\/a> is put through a thermal treatment to eliminate the plastic, leaving behind a metal or ceramic item.<\/p>\n

\u201cOnce this plastic-containing body goes through this treatment then what is left behind is pure metal or ceramic,\u201d explained ESA non-metallic materials and processes engineer Ugo Lafont. \u201cThe result is high-quality part<\/a>s with very good physical properties. So this cheap, simple technique can offer us additional part<\/a> manufacturing capability for space application<\/a>s with an expanded pallet of materials.\u201d<\/p>\n
