Part Unitization, Large-Format Printing
on Tap at On-Demand Webinar

In a webinar presented by the Institute of Electrical and Electronics Engineers, Denis Cormier, professor of industrial and systems engineering at the Rochester Institute of Technology, explains that while 3D metal printing of lattice structures promises to reduce weight and create heat sinks, the software code used to develop lattices can be "astronomically large." As a result, not every PC can handle it.

Also addressed in the webinar: part unitization. "You can throw the DFM [design for manufacturing] guidelines out the window," Cormier says. "There is no problem getting the part out of a mold."

However, complex, unitized parts can prove challenging when it comes to removing excess powder from internal channels. The webinar addresses this topic in great detail.

Also up for discussion: the trend toward printing larger parts, where the cost of metal powder can be a limiting factor; and the trend toward simulation-based design, which, says Cormier, can help engineers achieve uniform heating and a uniform microstructure.

Webinar: Atomization Improvements for AM Applications
Don't miss this important webinar produced by 3D Metal Printing magazine, slated for tomorrow afternoon (Thursday, June 8) at 2:00 p.m. EDT, describing how a scientific approach to improving powder quality, safety and yield is meeting specific customer requirements for metal additive manufacturing (AM). The webinar, presented by Joel Rieken of Praxair Surface Technologies, will provide information to help attendees:

  • Understand how to better select powders for their AM processes;
  • How to properly handle powder; and
  • How advancements from new atomization techniques improve finished part quality.

Rieken will present information on titanium-, nickel-, cobalt- and iron-based alloys used in multiple AM applications.


White Paper: Topology Optimization "Lightweights" Aluminum Part
This white paper posted to the website of 3D Metal Printing magazine describes a titanium topology-optimized (TiTO) 3D-printed satellite mount originally designed as a machined aluminum part. Read about the additive-manufacturing principles used to allow the redesigned part to be printed using the direct metal laser-sintering process, with minimal post-processing required. The result: Topology optimization removed 70 percent of the overall design volume, and reduced part weight by 61 percent.
