Polyamide (PA) materials are extensively used in Selective Laser Sintering (SLS) for producing functional components. Among them, DuraForm PA and DuraForm GF from 3D Systems, along with PA 2200 and PA 3200 GF from EOS, are widely adopted for their favourable mechanical and thermal properties. Glass-filled (GF) composites, composed of a polymer matrix reinforced with glass particles, provide enhanced stiffness and dimensional stability compared to unfilled PA materials. This study focuses on...
This research paper aims to study the effects of heat treatment on 14 mm reinforcing bars that are produced by the Libyan Iron and Steel Company. These operations were conducted in the quality control laboratory, and it was found that there are two types of 14 mm reinforcing bars: (G-40) and (G- 60). The difference between them is the percentage of carbon present in their chemical composition, as the percentage of carbon in the variety (G-40) ranges between 0.25% and 0.38%, and as for the...
