At Aerosint we’ve developed the Selective Powder Deposition (SPD), a technology that allows the user to make 2D patterns with multiple powders in any shape or form they desire. Our goal is to empower you with this technology to make materials and parts like none you’ve seen before. One way to achieve this is via direct pressure assisted sintering on multi-material powder constructs.
This is (by far) the first question people ask about the Aerosint process. And rightfully… When we print with two metal powders simultaneously, the unfused powder in the process inevitably ends-up being a mix of the two metal powders. Can the excess powder be recycled? Often not, or at least not easily and not fully.
With the onset of multi-material powder bed based additive manufacturing there is nothing that hinders us in imagining a soluble support approach for L-PBF, greatly facilitating parts post-processing.
A non-contact powder recoater may avoid common issues in fabrication of small and intricate parts in metal laser powder bed fusion
With selective powder deposition we can use virgin material for every part produced by laser powder bed fusion — and prevent waste
We can validate the utility of multi-metal laser powder bed fusion through “simple” material combinations with immediate industrial applications.
Using selective powder deposition, we can shape complex metal or ceramic preforms without costly pre-machined dies.
Multi-material powder deposition can elevate ordinary die pressing technology to the production of highly optimized parts.
Defining part models computationally by their boundaries alone won’t work when one part contains two or more materials.
This article is about the 3 use cases that we consider being the most promising for our powder deposition technology.
