AlSi10Mg is a lightweight, high-strength aluminium alloy that is widely used in the aerospace, automotive, and medical industries. Its unique combination of aluminium, silicon, and magnesium makes it an ideal material for additive manufacturing processes, such as 3D printing.
3D metal printing builds components by delivering the powdered metal and binder in alternative layers through a nozzle controlled by a computer system, working to a CAD drawing. The initial process does not achieve the required strength so parts must go through a secondary process which involves fusing another type of metal into the shape.
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 ...
It is also possible to use conventional gas metal arc welding attached to a 3D stage to 3-D print metals such as steel, bronze and aluminum. [ 67 ] [ 68 ] Low-cost open source RepRap -style 3-D printers have been outfitted with Arduino -based sensors and demonstrated reasonable metallurgical properties from conventional welding wire as feedstock.
[46] The 3D printing process for the SuperDraco engine dramatically reduces lead-time compared to the traditional cast parts, and "has superior strength, ductility, and fracture resistance, with a lower variability in materials properties." [47] Also in 2018, the FDA approved the first-ever 3D printed spine implant made from titanium using SLM ...
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.
3D printing, or additive manufacturing, is the construction of a three-dimensional object from a CAD model or a digital 3D model. [1] [2] [3] It can be done in a variety of processes in which material is deposited, joined or solidified under computer control, [4] with the material being added together (such as plastics, liquids or powder grains being fused), typically layer by layer.
Silicon powders are used in aluminum-silicon alloys for enhancing strength and castability, providing better durability under high-stress conditions. [4] It also improves the fluidity of molten aluminum which allows easier casting of complex shapes with fewer defects. [5] Small additions of titanium and boron serve to refine the grain. [6]
