Abstract
This work aims to identify the quality of polyamide PA3200 GF and reduce the orange-peel effect and consequent improvement of part quality. The research intends to study the orange-peel effect and its causes, and implement screening test to determine the range of laser sintering LS parameters for acceptable build quality. The work begins with the experimental procedure and examination of the orange-peel texture, followed by analysis of results, and determination of improvement and control of input parameters. The benchmarking of the sintered part designs and their geometric features were intended to allow for evaluation of the performance of the LS process in terms of the orange-peel effect. These investigations were intended to find a systematic approach to the setting of the baseline for the quality of powder in terms of minimum acceptable value of MFR that can be used without the occurrence of the orange-peel effect.
