Tooling

Transformative Tooling Reaches Applications Including Concrete and PVD Coating

Our reporting from tooling’s frontier finds custom tooling succeeding in applications not usually associated with 3D printing.

Video: “I Think You Ignore Additive Manufacturing at Your Peril”

I check in with Greg Morris of GE Additive, hearing his views on AM’s continuing promise and importance. Representatives of John Deere, Smith & Nephew, B&J Specialty and Tangible Solutions share their views on the same question.

Custom Tooling Unmasks Process Costs in Metal Coating

The tooling that had long been accepted was contributing to unnecessary manual labor for this PVD coater. Now, the company has improved its process with custom tools that are 3D-printed in production quantities.

Production

Impressions of Rapid + TCT 2018

Exhibitors offering additive technologies to challenge conventional production was a striking development this year, though some of those technologies are not yet obtainable.

Production

Applying Material Like Toner Promises AM at Speeds Like Injection Molding

The Stratasys-founded company Evolve debuts its STEP technology for production-scale additive processing.

AMUG Conference Celebrates 30th Anniversary with Record Attendance

Photos capture some of what I saw at the event this year. As this event continues to grow, it will need to adapt in order to continue to fulfill its valuable and long-standing role of serving AM’s users.

Video: Is There a Personnel Challenge in Additive Manufacturing?

Adam Clark of Tangible Solutions sees the personnel advancing. The discipline of conventional manufacturing is coming to additive.

Will Control Over Part Data Expand and Simplify AM Supply Chains?

Digital rights management for manufactured part files will enable OEMs to enforce manufacturing requirements at a distance, potentially providing an alternative to closely held relationships with suppliers of critical AM parts.

Automotive

Printing Solid, Simple Metal Parts in Minutes, Spee3D Process Is Competition for Casting

Kinetic energy additive process bonds metal not through melting, but with the use of compressed shop air.

Moldmaking

Linear Comes Full Circle

The relaunched company will focus on metal 3D printing of mold inserts with conformal cooling. The timing is great, because some high-volume molders have just finished proving that this solution works.

Machine Learning for Invention Will Aid and Be Aided By AM

Neural networks that learn by trial and error—learning, in fact, like a child—will map the constraints of AM systems, allowing part designs to be optimized for those systems.

Hybrid Manufacturing

Video: The Case for Hybrid Manufacturing in Moldmaking

Instead of relying on EDM to machine features recessed deep into the part, machine those features while 3D printing progresses, finishing them before they become hard to reach.
