A group of undergraduate students at the Swiss Federal Institute of Technology (ETH Zurich) has developed innovative 3D printing technology that produces multi-metal parts for the aerospace industry. This development stands out as a significant step in the field of 3D printing and opens the door to new manufacturing methods in the aerospace sector.
Swiss Federal Institute of Technology (ETH) Zurich Students Prototype Multi-Metallic 3D Printer for Spacecraft Components
Students at ETH Zurich have developed a rotating, multi-metallic laser powder bed fusion (LPBF) 3D printer prototype to produce spacecraft components faster than traditional methods.
Students Advancing Aerospace
The engineering motivation for this innovative technology stems from the need to create multi-metallic bi-liquid rocket nozzles capable of withstanding extreme temperatures and pressures. It is hoped that these nozzles will be used as part of ARIS, the Academic Space Initiative of Switzerland. The ARIS association aims to reach a boundary known as the Kármán Line, where the Earth's atmosphere ends, approximately 100 kilometers (62 miles) up.
The Kármán Line is the boundary named after Hungarian physicist Theodore von Kármán, where the Earth's atmosphere ends and the atmosphere becomes too thin for aircraft to support themselves with the lift they get from their wings. To travel and maintain flight in the thin atmosphere, aircraft need to go very fast. Above the Kármán Line, aircraft need to reach orbital velocity to fly or avoid falling back to Earth.
Laser Powder Bed Fusion (LPBF)
To support ARIS and under the RAPTURE Project, a group of undergraduate students led by Senior Scientist Michael Tucker and Professor Markus Bambech at ETH Zurich developed and tested an innovative multi-metal, rotating 3D printer in just nine months.
Traditional LPBF 3D printers operate on the principle of selecting a powder bed made of metal or polymer powder, where the desired part/component will be built, and using a powerful laser. The laser sinters/melts the powder, and once combined, the build platform is lowered for the new layer to form. Powder is supplied from a reservoir or hopper, and a recoater blade spreads a thin layer of powder onto the build platform, ready for laser-directed sintering. Once the part is built, it undergoes post-processing to meet safety and quality requirements.
Rotating Multi-Metallic 3D Printer
The RAPTURE machine developed by the students differs from traditional LPBF printers by using a unique rotating platform that allows powder-coated layers to be added and combined by the laser simultaneously, rather than sequentially. ETH
