dc.description.abstract | SLS technology is widely used in several industries worldwide mainly due to its ability to
manufacture complex geometry components with less effort compared to conventional
methods. Such technology uses materials in powder form, the most common ones are
polyamides (PA), polystyrenes, thermoplastic elastomers, and polyaryletherketones. Research
covers flexural PA12 specimens, with CAD model dimensions selected according to the ISO
178 standard, with 96x8x4 [mm] in bulk. Printing was performed on Fuse 1 (FormLabs,
Summerville, MA) machine with four batches, differing in printing orientation and printing
location. Vertical and horizontal orientations are applied, and each orientation is combined
with the printing location, i.e., in the middle and on the edge of the powder bed. Printed
specimens are scanned and obtained scans are then compared with original CAD model in the
GOM Inspect program. All four specimen batches have deviation maximum on lateral sides,
where the surface is minimal. Nearly 0.42 mm deviations are present in horizontally printed
specimens placed in the middle of the powder bed, and these values are maximal recorded
deviations. Worth mentioning are vertical specimens printed in the middle, which show not
only lateral deviations but posses 0.07 mm deviations on largest surface, i.e., on 96x8 mm
