As additive manufacturing emerges from a long infancy, the industry is grappling with a key challenge: A file format and design tools from the 20th century are being asked to do 21st century jobs.

When you walk into the Redeye On Demand facility in Eden Prairie, MN, you enter into one version of the factory of the future. There you will see a bank of 100 high-end Fortus fused-deposition modeling (FDM) machines from Stratasys that provide the capacity to build real, functional parts with production-grade thermoplastics directly from CAD data.

Micro components continue to shrink in size, demanding ever-greater precision and improved handling of parts with sub-micron-sized features. New approaches in micro machining technology include higher-precision systems from traditional micro machining developers, as well as techniques using additive manufacturing processes and semiconductor wafer-scale technology on the smallest of micro parts.

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.

Additive manufacturing (AM), or 3D printing, is a fast-growing field that offers many advantages over traditional techniques. It can create more complex parts than either machining or casting, can fuse different materials together, and is sometimes less expensive in low-volume or prototype applications.

If NASA’s Journey to Mars project succeeds, the astronauts who make the 140 million-mile (225 million-km) trip to the Red Planet in the 2030s will need someplace to stay. The space agency is looking at 3D printing, using on-site materials, to manufacture humanity’s first deep space home.

HP Inc. (Palo Alto, CA) said today it’s introducing an industrial-sized 3D printer and expanding its offering of materials for additive manufacturing.

Impossible Objects LLC, a Chicago-based company, has brought to market a new composites material manufacturing technology known as Composite-Based Additive Manufacturing (CBAM) 3D technology which produces Carbon Fiber Reinforced Plastic (CFRP) or Polymer Matrix Composite (PMC) parts.

Sciaky Inc. (Chicago) has staked its claim to being the leading provider of metal 3D printing solutions for large parts approved for land, sea, air, and space applications, with the latest success being its Electron Beam Additive Manufacturing (EBAM) technology. Sciaky was called upon to manufacture a titanium variable ballast (VB) tank for a submarine manufacturer.

When Desktop Metal introduced its “office-friendly” Studio metal prototype printer earlier this year, the company renewed attention on the issue of safer materials for binder jetting, an additive manufacturing method.
