Polyhydroxyalkanoates (PHAs) are biodegradable biopolymers (polyesters), produced by a wide range of bacterial strains. They are gaining increasing interest in different research fields, due to their sustainability and environmental-friendly properties. Additionally, PHAs are also biocompatible, which …

This study starts with a literature review on SLS-printed PA12 and how its ductility is influenced in the printing process as well as by post processing. The rest of the study focuses on one particular post processing technique, heat treatment under isostatic pressure, including an experimental phase …

Selective Laser Sintering (SLS) with Polyamide 12 is increasingly used for production of functional components for prototyping and end-use. Common grades of PA12 powders age and cause a stock of unsintered powder material that cannot be re-used within the SLS process. This research explores and validates …

Synthetic fibers, mainly polyethylene terephthalate (PET), polyamide (PA), polyacrylonitrile (PAN) and polypropylene (PP), are the most widely used polymers in the textile industry. These fibers surpass the production of natural fibers with a market share of 54.4%. The advantages of these fibers are …
