Direct pressure-assisted sintering of complex powder structures
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.
How do you recycle the mixed powders ?
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 Multi-Metal 3D printing
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.
Facilitating post-processing of printed parts using multi-material printing
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.
Rethinking doctor blades and counter-rotating rollers
A non-contact powder recoater may avoid common issues in fabrication of small and intricate parts in metal laser powder bed fusion
Making economical use of new feedstock in every build
With selective powder deposition we can use virgin material for every part produced by laser powder bed fusion — and prevent waste
One small step for metallurgy, one big step for additive manufacturing
We can validate the utility of multi-metal laser powder bed fusion through “simple” material combinations with immediate industrial applications.
Additive manufacturing for isostatic pressing
Selective powder deposition could be used to produce pre-filled constructs for direct high-pressure treatment.
Tool-free metal and ceramic forming with dies printed on-the-fly
Using selective powder deposition, we can shape complex metal or ceramic preforms without costly pre-machined dies.
An unconventional approach to improve conventional manufacturing
Multi-material powder deposition can elevate ordinary die pressing technology to the production of highly optimized parts.
Why multi-material additive manufacturing will change our approach to part design
Defining part models computationally by their boundaries alone won’t work when one part contains two or more materials.
