Optomec LENS Metal AM Systems Offer Minimal Footprint

Optomec has announced its LENS CS 600 and 800 Controlled Atmosphere DED systems for next-generation metal additive manufacturing.

Metal 3D Printing in a Machine Shop? Ask the Marines

A hybrid system combining metal 3D printing with machining gives the Marine Corps perhaps its most effective resource yet for obtaining needed hardware in the field. It also offers an extreme version of the experience a machine shop might have in adding metal AM to its capabilities.

Desktop Metal Releases Corrosion-Resistant Stainless Steel

Desktop Metal’s 316L stainless steel, developed for the Studio System metal 3D printing system, offers corrosion resistance at extreme temperatures.

Carnegie Mellon University and Argonne National Laboratory Seek to Understand Gas-Driven Micro Defects in Metal AM Parts

Better understanding of "keyhole" formations resulting from boiling metal will lead to better control over laser powder-bed fusion.

Three Cool Uses for Directed Energy Deposition

Most machining professionals don’t like to admit that they ever make mistakes, but every now and then wouldn’t it be nice to have an “eraser” to go back and repair a gouge or fix a nicked edge? Or maybe you took off a bit too much material on that last machining pass and you’d like to add it back? Well, directed energy deposition (DED) enables you to do that and more.

How a Solid-State Process Stood Firm Until Additive’s Moment

Early on, this company saw the promise of friction stir welding for building forms in layers. Few understood at the time. They understand now, in part because this process offers benefits such as blended materials and freedom from stress that other metal AM approaches can’t match.

DMG MORI SLM Machine Offers Focal Diameter of 35 Microns

Rapid 2019: The Lasertec 12 SLM is said to offer improved accuracy for powder-bed fusion.

When Is 3D Printing Cost Effective?

Hype continues to surround additive manufacturing. These three factors can help determine whether a part is worth 3D printing.

Digital Metal Achieves UL Certification

Digital Metal has been authorized to apply the Underwriters Laboratories (UL) mark to its DM P2500 metal binder jetting system, the first such system to receive the UL certification.

Grind to Finish: A Postprocessing Solution for Additive Manufacturing

3D printed metal parts typically feature little stock remaining for finishing. Grinding is potentially an effective solution for meeting final tolerances. An abrasive technology provider investigates grinding as a complement to AM.

Fabrisonic Hybrid Enables Solid-State Bonds at Low Temperatures

Rapid 2019: Fabrisonic LLC releases its SonicLayer 1200 machine which offers Ultrasonic Additive Manufacturing (UAM) technology at an affordable price, the company says.

Gas: The Silent Enabler of Additive Manufacturing

High-end metal additive manufacturing relies on the perfect gas composition to create products that meet the required material properties. But gas such as argon is also key to metal powder production, storage and postprocessing.
