Cold spray additive manufacturing (CSAM) (also called cold spray 3D printing) is a particular application of cold spraying, able to fabricate freestanding parts or to build features on existing components. During the process, fine powder particles are accelerated in a high-velocity compressed gas stream, and upon the impact on a substrate or ...
Alumide is a material used in 3D printing consisting of nylon filled with aluminium dust, its name being a combination of the words aluminium and polyamide. Models are printed by sintering a tray of powder, layer by layer. [1] While it is much stiffer than other materials used in 3D printing, it can also withstand much higher thermal loads ...
Printing: The process begins with printing the part using a filament containing metal powder bound in plastic. This filament, similar to that used in conventional FFF printers, is infused with metal. The printer deposits the metal-infused filament layer by layer, building up the shape of the part. These printed parts are referred to as "green ...
Direct metal laser sintering, or DMLS, uses a laser to sinter powdered metal into a solid object in gradual layers built upon each other. Cooling channels can be printed to any shape in this process, which lessens time and waste and improves quality. [2] Selective laser melting, or SLM, completely melts the powder to form a homogeneous part ...
Electron-beam additive manufacturing, or electron-beam melting (EBM) is a type of additive manufacturing, or 3D printing, for metal parts.The raw material (metal powder or wire) is placed under a vacuum and fused together from heating by an electron beam.
Also known as direct metal laser sintering (DMLS), the ASTM standard term is powder bed fusion (PBF). PBF is a rapid prototyping, 3D printing, or additive manufacturing technique designed to use a high power-density laser to melt and fuse metallic powders together. [2] [3]
