3D Printing
The 3D printing process builds a three-dimensional object using a computer-aided design (CAD) model, usually by successively adding material layer by layer, which is why it is also called additive manufacturing. The innovative technology lets anyone create a physical object from a digital model. All you need to do is make a design, transfer the file to a 3D printer, then bring your object to life. The process was devised in the 1980s and was initially called ‘rapid prototyping’.

3D Printing Methods
Fused Deposition Modelling(FDM)
Fused deposition modelling (FDM) is a common desktop 3D printing technology for plastic parts. An FDM printer functions by extruding a plastic filament layer-by-layer onto the build platform. It’s a cost-effective and quick method for producing physical models.
Selective Laser Sintering
This method is more common in industrial style prototyping settings, a laser melts together powdered plastic, ceramic, or other material, then spreads more powder on top, repeating the process to build the part layer by layer. Since SLS parts are made from real thermoplastic material, they are durable, suitable for functional testing, and can support living hinges and snap-fits.
Powder Bed and Binder
This process is similar to Laser Sintering, an inkjet head distributes binder to the correct location on a bed of powder.
Stereolithography
In this process, an ultraviolet laser hardens resin in a vat layer by layer until the part is built. It can quickly create high definition parts that can be machined. A stereolithograph apparatus (SLA) converts liquid plastic into solid objects in this method.
Generally in our ATL Labs we use 3D Printer which follows FDM (Fused Deposition Modelling) process.
