Metal 3D Printing

Formnext 2019 Emphasizes Complete Additive Manufacturing Process Chain — Well Beyond 3D Printing

The biggest AM event gets bigger. The sophistication of attendees advances. Materials, digital tools and postprocessing are prominent. Here are 10 impressions of this year’s show.

Wire Arc Additive Manufacturing Delivers Low Buy-To-Fly Ratios

Manufacturers in the aerospace industry buy expensive raw material with one common goal: to make it fly. To reduce its buy-to-fly ratio (the ratio of material inputs to final part output), this company turned to wire arc additive manufacturing to create near-net shape parts.

In Automotive, Is Additive Manufacturing an Answer for Die Cast Tooling?

The largest high-pressure die cast tool builder in North America is 3D printing die inserts and water jackets for major automakers. It’s a tough sell, but one company is succeeding — and it’s just getting started.

Largest ExOne Metal Binder Jetting System Yet Provides 160-Liter Build Volume

The design of this machine anticipates scale production, with compaction technology for repeatable part density and Industry 4.0 connectivity for lightly staffed AM factories.

Mazak, Oak Ridge National Laboratory Partner on Wire Additive R&D

Mazak Corporation and Oak Ridge National Laboratory’s manufacturing demonstration center in Oak Ridge, Tennessee, have entered into a cooperative research and development agreement.

Can 3D Printing Make a Better AM Build Plate? The Cool Parts Show S1E5

Ultrasonic metal additive manufacturing was used to create a build plate aimed at making powder bed fusion more effective. This episode of The Cool Parts Show looks at a part by AM, for AM.

6 Things I Learned about Metal 3D Printing at the AMIST

I sat in on one and a half days of a five-day class offered at the Additive Manufacturing Institute of Science and Technology (AMIST) in Louisville. Here’s just some of what I learned.

AM 101: Ultrasonic Additive Manufacturing

Going from additive to subtractive can be simple with Ultrasonic Additive Manufacturing (UAM). What is it and how does it work? Learn the basics in this 101 post.

Interlayer Laser Peening Shows Promise for 3D Printed Implants and Beyond

Research at the University of Nebraska-Lincoln illustrates how applying secondary processes between 3D-printed layers can have a ripple effect on part properties. Dr. Michael Sealy explains the potential for medical implants using Optomec’s LENS platform.

Topology Optimized 3D Printed Spine Implant: The Cool Parts Show S1E2

Medical contract manufacturer Tangible Solutions shares a titanium 3D printed spine implant with an unusual lattice structure in this episode of The Cool Parts Show.

The Cool Parts Show, Episode 1: This Rocket Fuel Injector Is a Solid Part That Contains a Working Motor

Our new video series debuts with a look at a solid metal part made through additive manufacturing that was built with a motor embedded inside. The motor sealed within the part adjusts the rocket’s fuel mixture while the rocket is in flight.

Velo3D: Avoiding Support Structures Means Metal AM Can Be a Solution for Direct Part Replacement

Because of the extent of the redesign they might call for, support structures can be an impediment to AM adoption. Reducing the need for support structures increases the viability of 3D printing for current parts.
