Höganäs Acquisition of H.C. Starck Division Advances AM Offerings

In a deal that closed earlier this year, Höganäs acquired a division of H.C. Starck that will advance its presence in surface coating and additive manufacturing.

Materials Are the Ingredients that Enable Additive

The July issue of Additive Manufacturing magazine examines developments in metal alloys, polymers, ceramics and active materials.

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.

Orion Gets a Lift from Electro-Static Dissipative (ESD) Material

NASA’s Orion spacecraft will include parts 3D-printed from electro-static dissipative Antero 800NA from Stratasys. Developing this material was an exercise in working within constraints.

Materials Are the Most Important Component in AM

You will see a lot of additive machines at IMTS. Success with those machines is determined by an underappreciated ingredient. Read our collection of recently published articles focused on materials.

Aluminum Alloy for 3D Printing Combines Benefits with Familiarity

IMTS 2018: Elementum 3D’s AL6061-RAM2% product is an aluminum 6061 material that achieves properties comparable to wrought 6061-T6 on existing laser powder-bed fusion equipment.

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. 

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.

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.

Kason 3D-ReKlaimer Recovers Metal 3D Printing Powder

The self-contained metal powder reclamation system uses multi-plane, inertial vibration and ultrasonic frequencies to sift metal powders. 

GKN and Porsche Develop AM Transmission Part Using New Metal Powder

Using a combination of metal powder-bed fusion and metal powder 20MnCr5, GKN Powder Metallurgy and Porsche 3D-printed an intricate differential housing with gear ring unit on a front traverse transmission. 

Carbon Releases Epoxy (EPX) 82 and Elastomeric Polyurethane (EPU) 41

Carbon’s Epoxy (EPX) 82 is a high-resolution and high-strength engineering material with long-term durability, and its Elastomeric Polyurethane (EPU) 41 is a production-scale elastomeric material offering higher resilience for making durable, elastic lattices.
