DESIGN AND FABRICATION OF 3D PRINTER WITH 2 AXIS MOVING BED 4 DEGREE OF FREEDOM

Mechanical engineering

Abstract—3D printing is an additive manufacturing technique in which 3D objects are printed with the help of CAD (computer-aided design) software. For additive manufacturing various processes are used such as-(a) SLS (selective laser sintering), (b) EBM (electron beam machining), (c) LOM (laminated object manufacturing), (d) DLP (digital light processing), (e) FDM (fused deposition method), etc. In this paper, we have focused on the design and fabrication of 3D printer with 3 Axis moving bed (4 degree of freedom). The 4degree of freedom are- the bed moving in 3 axes are x-y-z which are first 3 degree of freedom and the fourth degree of freedom, the bed is rotating along xy- axis. The process used in our 3D printer is FDM technology (Fused Deposition Method). There are different types of materials PLA (polylactic acid), ABS (acrylonitrile butadiene styrene), HIPS (high impact polystyrene), etc used in this process. By heating any of the filament material to its melting point and it is deposited layer by layer. Combination of many layers of such type will give us a final 3D model and which can be constructed economically.
