Additive Manufacturing Moves Toward Tailored Materials

A conversation with Carpenter Technology suggests that AM is moving past existing materials toward specialized and eventually fully custom options. The company’s CarTech Puris 5+ titanium powder is one illustration. 

Hermle Combines Metal Powder Application Process with Five-Axis Machining

Hermle integrated its MPA technology, a process where metal powder is applied by kinetic compacting to build completely sealed materials, in a Hermle five-axis machining center to create parts with highly complex inner geometries.

Roush Uses Engine Cylinder Head to Prove Out Additive Manufacturing

A 3D-printed cylinder head investigation reveals the possibilities of additive manufacturing.

Solving a Materials Challenge in Soft Robotics

A team from the University of Minnesota and the Army Research Lab has developed processes for fully 3D printing soft dielectric elastomer actuators without postprocessing steps.

How One Device Inspects Both Parts and Powder in Metal AM

A scanning electron microscope analyzes the shape and composition of grains of powder as well as inclusions and voids in the part’s surface.

One-Piece Robot Gripper Actuated by Shop Air

The pneumatic gripper 3D-printed as a complete working unit has demonstrated its effectiveness for continuous operation over time. It is one illustration of the role additive is liable to play in making robotic automation easier.

Printing End-Use Parts from High-Performance Ceramics

The lithography-based ceramic manufacturing (LCM) process allows the cost-effective production of ceramic parts even for a batch size of one.

The Third Bucket and the Conversion of Production: A Perspective on Polymer Development for AM

Sabic sees 3D printing taking plastics where they have not gone before, but end-user needs will push the capabilities of 3D printers.
