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.

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.

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.

Renishaw, Cobra Work to Optimize Design Process

Renishaw worked with Michigan-based Cobra Aero to improve the engine manufacturer’s design processes for aircraft and motorcycle engines.

Somerset Community College Offers Metal AM Technology Training

Somerset Community College has added metal additive manufacturing technology to its advanced manufacturing capabilities as an institution. The college says it is also the first institution of higher education in Kentucky to offer a technician certificate in 3D printing.

Video: Controlled Porosity Can Be Functional Advantage Realized via 3D Printing

A wall of metal that looks solid is actually 90% dense, allowing gas to pass through. Mold venting is one application.
