What is 3D Printing and how it Works?


3D printing, also known as additive manufacturing, is a procedure by which a computer-generated design is employed to construct a three-dimensional object layer by layer. This is contrary to subtractive manufacturing processes, which involve cutting a completed design from a larger block of material. Consequently, 3D printing service in Perth reduces material waste.

How is 3D Printing Performed?

Similar to conventional printers, 3D printers utilize multiple technologies. Fused Deposition Modelling (FDM), and Fused Filament Fabrication (FFF), are the most well-known. In this technique, a filament made of acrylonitrile butadiene styrene, polylactic acid, or another thermoplastic is liquefied and deposited in layers through a heated extrusion nozzle.

Stereo lithography (SLA) is another method utilized in 3D printing that employs a laser and resin. It is a 3D Printing technique that employs a computer-controlled, moving laser beam preprogramed using CAM/CAD software. 

In addition, there is 3D printing using Digital Light Projectors (DLP). This method exposes a liquid polymer to digital light processing projector light. This solidifies the polymer layer by layer until the object is constructed. 

Moreover, multi-jet modelling is a 3D printing technique similar to inkjet printing in which a pigmented, glue-like binder is sprayed onto successive layers of material to form the object. This technique is one of the few that supports multicolour printing and is one of the quickest.

Utilizing a high-powered laser, selective laser sintering (SLS) fuses plastic, metal, ceramic, or glass particulates. In addition, electron beam melting (EBM) employs a beam of electrons to dissolve metal material layer by layer. Titanium is frequently combined with EBM to create medical implants and aircraft components. Depending on the technique, 3D printers can use various materials, including stainless steel engraving, aluminium, titanium, plastics and polymers.
