Sintavia: New facility signals the move towards volume metal Additive Manufacturing for aerospace and defence
In May 2019, US-based Sintavia, LLC opened a state-of-the-art facility in Hollywood, Florida, dedicated to the volume production of metal additively manufactured components for the aerospace and defence sector, marking a significant expansion of the company’s production capacity.
Debbie Sniderman visited the new facility on behalf of Metal Additive Manufacturing magazine and reports on the company’s ambitious plans and its management’s views on the ongoing evolution of the industry.
Thinking about metal Binder Jetting or FFF? Here is (almost) everything you need to know about sintering
With the arrival of high-volume metal Binder Jet systems and a growing interest in metal Fused Filament Fabrication, the AM industry is set for a new phase of growth. The ability to use this new generation of systems for the production of ‘green’ parts is, however, only half of the story.
The sintering of these parts to create large quantities of finished product to a consistent quality requires both an investment in furnaces that can cost in excess of $1 million each, and a thorough understanding of sintering.
In this article, Prof Randall German, the leading authority on the science of sintering, outlines the process and its core challenges.
Velo3D: How a ‘support-free’ Laser Powder Bed Fusion process could remove roadblocks to serial Additive Manufacturing
With its Sapphire machine and Flow build preparation software capable of highly-controlled, virtually support-free Additive Manufacturing, Velo3D is pushing the limits of what is possible with Laser Powder Bed Fusion (L-PBF). Since launching its first machine in 2018, the California-based company has seen success with a range of highly complex parts which would challenge even the most experienced AM engineer.
In this article, Zach Murphree, Velo3D’s Vice President of Technical Partnerships, explains the key factors which set the company’s process apart from the wider AM market.
