A Review of Methods Used to Reduce the Effects of High Temperature Associated with Polyamide 12 and Polypropylene Laser Sintering

Table 2

Advantages and Disadvantages of FDM.

Advantages	Disadvantages
Low or moderate cost of the equipment	Not suitable for printing sharp edges, thin walls, or acute angles and, hence suffers some limitation of design
Has a wide array of colourful materials for printing	Requires support structures, which affects surface finish
Suitable for medium-sized components	The dimensional and geometrical accuracy is not very accurate
Low or moderate postprocessing cost	Difficulties in regulating the build chamber temperature affects the printed parts
Reduced lead time compared to SLS [5]	The tensile strength of printed components is much less than for injection moulded counterparts [6]
Capable of deposition of diverse materials, which include polycarbonate, acrylonitrile butadiene styrene, and polylactic acid polymers [6]	Affected by lack of homogeneity in diverse materials, which reduces the mechanical strength of printed parts [6]
