New Multi Material 3D Printing Combines Different Metals and Ceramics into Single Part

The Fraunhofer family of German research institutes is endlessly inventing novel methods for manufacturing and supplementary technologies. The latest, this time from the Fraunhofer Institute for Ceramic Technologies and Systems (IKTS), is a multi-material ink jetting system capable of 3D printing multiple metals or ceramics in a single build.

 .

To demonstrate the power of the process, the Fraunhofer IKTS researchers 3D printed a ceramic satellite with built-in ignition. The multi material jetting system developed by Fraunhofer IKTS. The technology is similar to existing polymer inkjet 3D printing technologies, like PolyJet from Stratasys; however, it begins with a ceramic or metal powder mixed into a thermoplastic binder. This slurry is then melted within micro-dosing systems at temperatures of about 100°C and then deposited at rates of up to 60 mm and 1,000 drops a second, with droplets ranging in size from 300 to 1,000 μm and resulting in layers […]
