3D Printing in Space: A Thermoplastic for Additive Manufacturing from Stratasys
Equipment used in space encounters extreme environment, for example, large temperature changes in short periods of time, extreme radiations, and so on. One problem encountered in space is rapid build-up of electrostatic charge. To address such conditions, Stratasys Advanced Materials has developed ESD PEKK, a thermoplastic for additive manufacturing that has electrostatic dissipative (ESD) qualities. The ESD properties combined with excellent mechanical and thermal properties makes ESD PEKK suitable for advanced electronics applications, for example, for use in space.
Arcam Uses Electron Beam Melting (EBM) for 3D Printing Metal Implants
According to Arcam,” is a Swedish company founded in 1997. Arcam provides cost-effective 3D printing solutions for metal parts. The Arcam EBM (Electronic Beam Melting) builds metal parts from metal powder by melting the metal powder with a powerful electron beam. The electron beam is precisely controlled using electromagnetic coils”.
Arcam uses EBM technology to manufacture patient-specific orthopedic implants. Computer Tomography (CT) is used to build a CAD model of a patient-specific implant and EBM technology is used to 3D print the part from the CAD model.
