During the testing of the new method, no hazardous situations were reported, and the air quality remained within acceptable limits.

Instead of mixing it with silicon oil and sand, as it did before, the new procedure involves mixing the powder condensate waste with a removable resin instead. Members of AMGTA (photo credits: Business Wire) A New SolutionĪfter researching a solution to overcome the obstacles faced by the hazardous waste, Sintavia developed a new promising process. This special kind of powder condensate is a unique waste stream, that is composed of the splatter sieved out of a reused batch of metal powder. By looking at it from both environmental and commercial standpoints, the disposal of that hazardous waste has been a challenging question, to which an innovative answer was desperately needed. However, despite its many benefits, it does have several downsides, including issues related to disposal of condensate created during the process. The aerospace, automotive, and medical sectors are especially fond of this technology, which gives them opportunities no other technologies can provide. You are probably aware that Powder Bed Fusion (PBF) is an additive manufacturing process especially popular with industries seeking a manufacturing method that allows them to design more complex parts. Given the concerns many have around the issue of recycling powder, this could be a significant step forward for the industry in terms of sustainability. The AMGTA, originally founded to promote the environmental benefits of additive manufacturing, stated that the new procedure, created by Sintavia, a member of the organization and KBM Advanced Materials, essentially includes mixing powder condensate waste with a removable resin, which makes the waste non-hazardous and thus safe to be transported to a recycling plant. A new report has been released by the Additive Manufacturer Green Trade Association (AMGTA) outlining a new process to make it possible to passivate metal condensate waste for transport and recycling.
