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

Table 1

A comparison between FDM and SLS AM technologies.

FDM	SLS
Involves extrusion of a filament	Involves fusion of powder particles
Requires support structures	No need for support structures since the unsintered powder serves this purpose
Suitable for office use since a majority of the printers are desktop-sized and, thus, require less space.	Most of printers require significant space and are commonly utilized for industrial applications
