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 material can be used to create smooth surface finishes, which enables an optimized production process that streamlines postprocessing steps, thereby saving time and further reducing costs for producing complex smooth parts.
The companies say this qualification will support Caracol in its efforts to offer Airtech’s Dahltram resins to its customers across the globe.
In a recent case study, Alpine Advanced Materials partnered with Nexa3D to produce 3D printed tooling for injection molded composites. Utilizing Nexa3D’s XiP desktop 3D printer and its Freeform Injection Molding process, Alpine was able to reduce prototype tooling production time and cost alike for its customers.
OnAdditive offers aftermarket upgrade for 3ntr A2, A4 3D printers | Gardner Business Media introduces new editorial roles covering robots and autonomy, and sustainability | HP’s 3D HR PA 12 S polymer material creates smooth finishes for cost-efficient parts production
The metal powder reprocessing system transfers material to 3D printers, recovers the unused material, screens it and then returns the material to the machine or a container for future use.
The award recipients are expected to collaborate with small businesses to bolster applicable knowledge, best practices and data to address the needs of the broader additive manufacturing supply chain.
The project focuses on advancing the ability to print a thermoset composite material that can transform the way an aircraft structure is designed, fabricated and sustained for limited-life aircraft.
Powder metallurgy company Alpha Precision Group (APG) is applying a particular class of metal 3D printing technology for both rapid iteration in development and flexibility in production.
The collaboration will increase accessibility of Sandvik’s Osprey metal powders, which includes premium titanium alloys and copper powder, as well as nickel-based superalloys, cobalt-chrome and ultrahard maraging steels.
