The Additive Manufacturer Green Trade Association (AMGTA), a global trade organization created to promote the environmental benefits of additive manufacturing (AM) releases a report outlining the requirements to passivate metal condensate waste for transport and recycling.

This report constitutes the second most important resource the organization shared as part of its activities – the first one being a publication on Sustainability in Additive Manufacturing. The announcement follows the appointment ofSherri Monroe as new Executive Director of the organization.

The new process, which was developed by AMGTA founding member, Sintavia, and KBM Advanced Materials, involves mixing powder condensate waste with a removable resin, which renders the waste non-hazardous and shippable to a recycling plant.

“Today’s report is a must-read for any company involved in laser powder bed fusion metal additive manufacturing,” said Sherri Monroe, the AMGTA’s Executive Director. “Not only does this new process reduce transportation costs, but it is also reversible, meaning that metal recycling companies can have unsoiled access to the underlying powder once it is received—thus allowing for the potential to recycle waste material that previously had to be put in a hazardous waste landfill.”

Metal condensate, which is the term used for excess soot and powder that is blown off of a build plate during the powder bed fusion additive manufacturing process, had previously been treated as a hazardous material and disposed of as such at a very high cost.

“I hope that other companies adopt this new process, as it will reduce their transportation costs since the underlying material is no longer hazardous,” said Brian Neff, the AMGTA’s Board Chair and CEO of Sintavia. “This report is an excellent example of the AMGTA taking a leadership role in developing sustainable use practices for additive manufacturing.”
