In machining, a part’s form may change in the process, but its material properties end as they started. In additive, the 3D printing process determines the part's shape as well as its material properties. Variables like processing temperatures, nozzle diameter or laser spot size, gas flow, and more can affect layer adhesion, porosity and density of the final material. The main classes of materials used in 3D printing today are polymers, metals, composites, ceramics and sand
The study evaluated three key metal AM feedstock processing approaches — gas atomization, mechanical milling (specifically ball milling) and wire drawing — to determine specific energy requirements for producing feedstock materials.
The zirconia materials are now qualified for use in the production of the world’s thinnest cosmetic veneers, which require significantly less tooth preparation or grinding, thereby preserving more of the patient’s natural enamel.
Following a successful beta release, the Material Hub is now openly accessible to the broader additive manufacturing community. It contains a collection of more than 400 polymer materials which have been compiled in collaboration with more than 25 material providers.
Laser powder bed fusion and directed energy deposition combine for an integrated multi-metal rocket propulsion system that will save cost and time for NASA. The Cool Parts Show visits NASA’s Marshall Space Flight Center.
The EOS M 290 1kW metal printer features a one-kilowatt laser with the flexible, midsize frame to deliver the power needed to maximize production of industrial applications for copper and copper alloy, with more materials coming.
Startup Fited and Brightlands Materials Center have developed a lighter weight, thinner CFRP corrective brace, including pressure sensors made from continuous carbon fibers.
This technology gives manufacturers the ability to build onto existing parts with high precision and utilize a variety of materials, reducing lead times and minimizing postprocessing requirements.
The Meltio M600 can seamlessly integrate into machine shops and production environments, enabling not only the printing of entire metal parts but also the addition of features to existing components and the repair of damaged surfaces.
The FDA clearance now enables widespread adoption of 3D Systems’ self-contained, cleanroom environment-based printing system, the EXT 220 MED, with medical-grade PEEK materials to deliver patient-specific cranial reconstruction solutions.
Meltio M600 metal 3D printer employs probing, quick-change workholding and wire material stock to permit production in coordination with CNC machines.
