One of the early applications for 3D printing/additive manufacturing (AM) was in the medical industry. As the machines and materials have improved, the use of these technologies expanded into almost every application. In medical, there are unique challenges as patient safety is paramount and government regulation and insurance issues structure what can and will be done.

Additive Manufacturing (AM) machines making metal parts have been out there for a dozen years. The machines have improved since the initial offerings and the number of companies that now produce them have increased exponentially. Many companies are now ready to invest in this maturing technology, and there are many more companies with machines that vary in technology and materials. Even the experts in AM are having difficulty keeping track of all of the new offerings.

PITTSBURGH — Stratasys Ltd. introduced a prototype of a 3D printing system that maintains low-volume output continuously as the company moves to expand its presence in industrial production.

Impossible Objects announced today the launch of Model One, its pilot 3D printing machine to revolutionize high-volume manufacturing and initial customer deployments with select Fortune 500 customers. The announcement took place at the RAPID+TCT 3D printing and additive manufacturing conference.

The pace of 3D printing adoption will accelerate, a General Electric Co. executive said during an address at RAPID + TCT today.

Q&A with David Klotz, president and CEO of Tebis America Inc. in Troy, Michigan

Oerlikon announced today that it has signed an agreement to acquire Scoperta Inc., an innovative solution provider in advanced materials development, based in California, USA.

You don’t have to look too far to find tooling presetters that fit the machining requirements of just about any size shop. The value of off-line tool presetting—rather than stopping machine spindles to touch off tools as machines sit idle—continues to prove itself invaluable, especially to the smallest first-time user shops.

When first introduced in the late 1970s, cutting tool coatings—especially titanium nitride (TiN)—were embraced by tool manufacturers for their ability to extend tool life. As workforce materials have expanded from conventional ferrous and nonferrous metals to exotic alloys, composites, ceramics, and others, coatings have likewise progressed and, thanks to new formulations and deposition methods, are extending cutting tool capabilities as well as tool life.

Manufacturing Engineering asked thought leaders at five companies for their views on challenges and trends facing the metalworking industry.
