Selective powder deposition can be utilized to furnace sinter intricate glass objects by using alumina beads as a non-fusible support powder.
Field-assisted sintering (FAST), also referred to as Spark Plasma Sintering (SPS), is a powder metallurgy technique used to produce dense and high-performance materials by applying pulsed electric current and pressure…
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.
Use cases for Dual-Metal 3D printing are unlimited and can help companies find solutions to some of their unsolved technical challenges. Below we share 7 hot potential uses for multi-metal printing along with some inspirational applications.
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.
Selective powder deposition could be used to produce pre-filled constructs for direct high-pressure treatment.
