3D Printing an Additive Manufacturing technique
Additive Manufacturing (AM) is really an evolving 3D printing technique that facilitates the design and rapid development of complicated materials with intrinsic microstructures. 3D printing development has allowed manufacturing firms to grow from concept design and 3DP to fast end consumer manufacturing. Additive manufacturing allows the parts to be crafted in a layer by layer manner, the contrast to traditional manufacturing techniques focused on machining, forging and subtractive processes in order to produce the finished product. AM uses computer-aided design tools to plan and monitor the nozzle and stage of a 3D printing device for virtual objects.
Applications of Additive Manufacturing:
Polymers are the most widely used components for additive manufacturing because of their flexibility and wide variety of mechanical and chemical properties. Additive manufacturing polymers comprise thermoplastics, elastomers, polymers, biopolymers and polymers mixed with biological materials, as well as thermoplastics. With the architectural design and choice of polymers, we get an improved materials, mechanical properties, porosity, and stability can be created. This creation of multi-functional 3D polymer-based printing materials for the manufacture of medicinal equipment, electronic devices and items that are applicable to aircraft.
History of 3D Printing:
3D printing is an additive manufacturing technique (AM), which enables the layer-by – layer creation of parts with complicated geometries. When an Engineer “Charles Hull” who brought the first printer to the market in 1986, and after that 3D printers became popular. The first stereolithography (SLA) technique was invented by Charles Hull for the quick creation and production of tiny plastic prototypes. Stereo lithography uses light to enable polymers inside a resin to build 3D, complex shapes (the reaction process is called as photo polymerization). The firm “3D Systems” commercialized this SLA system in 1987.
After this discovery, considerable endeavour has been made to manufacture a range of plastics in machines. A couple of the techniques currently available in the commercial market are Fusion Deposition Modelling (FDM) and Direct Ink Writing (DIW).
