In the world of developing technology, 3d printing has been replaced the entire manufacturing system with its improved version of building parts layer by layer using an additive approach and new trends. In the present article, a comprehensive study has been carried out for comparing it with the traditional manufacturing method for production of components, complex objects for hundreds of different applications. 3D printing technology is extremely versatile and rapid process, accelerate innovation and reduce energy usage, minimize material and compress supply chains. This paper also describes the feed mechanism and process related information, supporting material, software used in a 3D printer and some recent developments in 3D printing technology.
FDM in 3D Printing
Fused Deposition Modelling (FDM)is an Additive Manufacturing Technology for printing 3D objects layer by layer.
The main purpose of the research is to develop a low-cost 3D Printer using easily available materials and conventional methods for fabrication which can be used to print objects confined within 300 x 250 x 300 (mm) Printing Area.
Many Industries uses this 3D Printing method for developing the prototype for analysis. Here we do 3D Printing in ABS, 3D Printing in PLA.
SLA 3D Printing
Stereolithography is a light-based process that builds individual layers of a model with liquid polymer, hardened by a laser beam.
The laser is directed and controlled by two galvanometers. After each layer, the resin tank peels away to release the hardened material. The build platform then moves up from 25 to 200 microns, depending on the chosen layer height, to prepare for the process of solidifying the next layer.
The part appears to be built upside down, which is called inverse stereolithography. Here we do 3d printing in resin, 3D Printing in accura60 (transparent in color), 3D printing in accura25(white in color).
SLS 3D Printing
Selective Laser Sintering (SLS) is a third and highly versatile AM process that creates solid parts by tracing a laser beam, focused onto a thin layer of powder, in a 2D pattern.
The powder is heated and fused into a solid connected pattern as it absorbs the electromagnetic
radiation emitted from the laser. 3D structures are fabricated by repeating this process layer-by-layer as new layers of power are laid over the previously fused layers.
A key advantage of SLS is the ability to construct overhanging regions which are either inaccessible using other processes or possible only with appropriate support materials. In SLS, unfused powder lying outside of the fused pattern remains within the build volume and acts as support material for subsequent layers, enabling the formation of dramatic overhangs and bifurcations. Here we do 3d printing in powder, 3d printing in Nylon (i.e. Nylon 3D Printing).
Polyjet 3D Printing
A carriage — with four or more inkjet heads and ultraviolet (UV) lamps — traverses the workspace, depositing tiny droplets of photopolymers, materials that solidify when exposed to UV light.
After printing a thin layer of material, the process repeats until a complete 3D object is formed.
These well-established technologies create models or finished goods for industries that span jewelry and architecture to aerospace and consumer electronics manufacturing.
Metal 3D Printing
3D Era Technology has the facility to do 3D Metal Printing.
Its quite hard to manufacture complex metal parts like clips, pins, screws with casting or machining. Where 3D printing gives versatility to do it in the easiest way.
We can manufacture components in Steel 420, Steel 316, Silver, Brass, Bronze, Copper, Aluminium and Gold plated using 3D metal printing.
