PRINTING ORIENTATION AND PLACE INFLUENCING THE COMPRESSIVE STRENGTH OF POLYAMID 12 SPECIMENS OBTAINED BY SLS TECHNOLOGY

Abstract

This research aims to determine how the orientation and placement of printing impacts the compressive strength of specimens manufactured by Selective Laser Sintering (SLS). The research includes compressive specimens in which the CAD model dimensions are selected according to the ISO 604 standard, and specimen geometry Ø10x20 mm in bulk. All specimen configurations are additively manufactured in two different printing orientations, horizontal and vertical, and printed in the middle and on the edge of the powder bed. All specimens are additively manufactured using Polyamide 12 (PA 12) material on a Fuse 1 device (FormLabs, located in Summerville, MA). Compressive strength testing was carried out using a Shimadzu AGS-X universal testing machine (Shimadzu Corp., Kyoto, Japan).
