Researchers from the Georgia Institute of Technology (Atlanta) and two other institutions have developed a new 3D printing method to create objects that can permanently transform into a range of different shapes in response to heat.

Additive manufacturing is both growing and coping with growing pains. Companies “have to find ways to streamline” polishing and other finishing processes of 3D printed parts, industry consultant Terry Wohlers said today during a speech at RAPID + TCT.

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.

Secure, accurate workholding sets the stage for consistent machining productivity. Depending on the parts and processes involved, workholding can be as simple and temporary as a plain vise or clamp or as complex and permanent as a machined and fabricated fixture that is custom-designed to hold a unique part.

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.

Coolant is a key component to successful centerless grinding but is often overlooked. Many coolant delivery systems for centerless grinders are under engineered and are often neglected.

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

Tool life, geometry, and stability largely depend on proper edge preparation. Tool Flo, located in Houston, TX, is a manufacturer of carbide cutting tools such as inserts for threading, turning, and milling. The company uses optical 3D measurement systems from Alicona Corp. (Bartlett, IL) in the quality assurance of inserts.

When it comes to creative workholding solutions, Kurt Industrial Products Division doesn’t hesitate to replace one or even two of its old vises with a new one to get a better product.

In what shouldn’t be too much of a surprise, challenges for advanced grinding technology from high tech industries range from handling the most difficult-to-machine materials for aerospace jet engine turbines to series production on automotive drive train lines.
