Answer :
P-3, Q-4, R-2
Solution :
Fused deposition modeling :
- Fused deposition modeling is an additive manufacturing process in which the melt extrusion method is used to place filaments of thermoplastic polymer and polyacid materials following a certain pattern to produce a three-dimensional physical model. This process uses polymers as raw materials or filaments.
Laminated object manufacturing :
- It is a rapid prototyping system, in it, layers of adhesive-coated paper, plastic or metal laminates are successfully glued together and cut to shape with a knife or laser cutter.
- Solid physical model is made by stacking layers of sheet stock, each an outline of the cross-sectional shape of a CAD model that is sliced into layers.
- Starting sheet stock includes paper, thermoplastic, cellulose, green compacted metals, or fibre-reinforced materials
Selective laser sintering :
- It is a type of powder bed fusion wherein a bed of powder polymer, resin or metal is targeted partially (sintering) or fully (melting) by a high power directional heating source such as a laser that results in a solidified layer of fused powder.
