EnvisionTEC CEO Al Siblani—whose firm is being purchased by Desktop Metal—discusses photopolymers’ move from prototyping to production. He gets into how he sees the sale will impact his company, as well as Desktop Metal and the 3D printing market in general. For the uninitiated, he also patiently explains how the 3d printing of polymers has progressed over the years. Last but not least, he details EnvisionTEC’s plans for growth—and asserts that the cost of 3D printing has reached a point where it is disrupting plastics.

Cybersecurity is growing more critical every year. Much of the focus has been on protecting information technology (IT) assets, and operational technology security can be been overlooked. In this episode, Alan Rooks, Editor in Chief of Manufacturing Engineering magazine, talks with Michael Rothschild, Senior Director of Marketing for Tenable about what has changed to cause operational technology security to gain a high profile; how OT environments are different from, and similar to IT; what types of attacks are impacting OT environments; what can happen if an OT attack is successful; common methods for detecting OT based attacks; and how proactive security is a powerful strategy for OT security.

Additive manufacturing, or 3D printing, has been a game changer in how products are designed, produced and manufactured. But 3D printed parts don’t just come out of the machine ready to use, sometimes intensive manual post-processing is required. Jeff Mize, CEO of PostProcess Technologies, sits down with Chris Mahar, Associate Editor, to discuss their automated post-processing technology and how fully digitalized additive manufacturing is further benefiting the industry.

John Deere’s Eric Johnson discusses the company’s additive manufacturing journey—with an eye toward helping small and medium businesses get going in AM. Learn about the early days of getting one of the first AM parts, as well as unrealistic expectations of the technology and how John Deere is creating value with the technology today. Finally, Johnson provides tips on unlocking the value of AM for your business in five key applications.
