The term 3D printing, widely referred to as additive manufacturing, is a family of processes that produces objects by adding material in layers that correspond to a successive cross-section of a 3D model. Plastics and metal alloys are the most commonly used materials for 3D printing, but they can nearly work on everything from concrete to living tissue.
The object which is needed to be 3D printed is first modelled in CAD software with specific dimensions. Then the CAD file is sliced using slicing software. Slicers are the easiest way to go from a 3D model to a printed part because they take a CAD model, slice it into layers and turn the model into G-code. The slicer software also includes 3D printer settings like temperature, layer height, print speed, etc. to the G-code. The 3D printer can read this G-code and make the model layer by layer following the instructions set in the G-code. Full video
There are various types of 3D printing techniques, one such technique is fused deposition modelling, in which desired material is heated to its melting point and fused together in a layer-by-layer fashion. There are four types of fused deposition modelling 3D printers: cartesian, polar, delta, and SCARA. The most commonly available fused deposition modelling printers are of the cartesian type which means the printer uses cartesian coordinate points to perform 3D printing. Delta 3D printers use arms that are fixed to vertical axes to perform 3D printing. In function, these are similar to cartesian 3D printers but faster and have a high print quality. SCARA (Selective Compliance Assembly Robot Arm) is a complex 3D printer that uses a printhead attached to a robotic arm to 3D objects. To download the complete report click the button below
