3D Printing EOS Tungsten W1 & EOS FeNi36
Special Metals for 3D Printing
EOS’s Special product group includes EOS Tungsten W1 - a pure tungsten alloy for thin-walled X-ray guidance structures in medical and industrial imaging - and EOS FeNi36, supporting applications where exceptional thermal stability is needed.
Both materials were designed and tested for use with EOS metal systems and are shipped with a material test certificate (according to EN 10204, Type 3.1) showing the results of the QA testing regarding the chemical composition and powder properties.
EOS also offers various processes for EOS FeNi36 with the optimal combination of parameters (e.g. laser power, layer thickness, etc.) at different build speeds. For EOS Tungsten W1, EOS offers process consulting services.
