Abstract- 3D printing is an additive manufacturing technology where 3D objects are printed with the help of CAD (computer- aided design) software’s. There are many Different processes available in 3D printing technology such as (1) EBM (electron beam machining), (2) DLP (digital light processing), (3) FDM (fused deposition method), (4) LOM (laminated object manufacturing), (5) SLS (selective laser sintering), etc.This is a research paper on 3D printing and the reason to make prototypes of an objects in a manufacturing industries with the help of various materials used in 3D printing and their properties, become a notable topic in technological aspects.In this project, we have focused on the design and fabrication of a portable 3D printer of bed volume (220 x 220 x 250 mm) which can be constructed economically. We has been using 4 axis mechanisms where 3 axes are x-y-z and the fourth axis is an extruder.The process used by us is FDM technology, in which different materials like PLA (polylactic acid), ABS (acrylonitrile butadiene styrene), HIPS (high impact polystyrene), etc are used.

Keywords- 3D Printing, Fused deposition molding (FDM), Additive Manufacturing Technology (AM), Portable Machine, Engineering and Technology.
