One of the things people first associate with increasing productivity in Laser Powder Bed Fusion is increasing the number of lasers working at any one time. The full-field lasers on Additive Industries' MetalFAB1 have many advantages as all lasers effectively…
In his July article, Why a Focus on Quality is Needed to Grow the Additive Manufacturing Industry, my colleague Ron Fisher talked about how quality control is one of the inhibitors slowing the potential growth of the 3D metal printing…
In a recent podcast interview for SME Media, editor Chris Mahar asked me an intriguing question: Why, in your opinion, hasn’t the metal additive manufacturing (AM) industry catapulted into mass industrialization, and how can Sigma solve that problem? I will…
This new technical paper reflects a collaboration between ANSYS Inc.’s Additive Team, Sigma Labs and National Institute of Standards and Technology. The study compares thermal history capabilities from ANSYS additive manufacturing simulation solutions with thermal imaging results from Sigma Labs…
Quality control of laser additive manufactured medical implants is of great interest, especially if nondestructive quality control can be performed on parts before implantation. In-process quality assurance using melt pool-plasma radiated emissions can identify the presence of thermally generated anomalies…
Two students from The ASK Academy, a Rio Rancho, New Mexico charter school focused on STEM and biomedical engineering, came to Sigma for help with a project. Abigail Catanzaro and Garnet Waldrop, both entering 8th grade, needed a cover and…
