3D scanning - Opis:
- The purpose of the undertaken research work is to analyze the torsional strength of standard samples with a circular cross-section, produced additively using the SLS (Selective Laser Sintering) technique – sintering PA2200 polyamide powders. The studies conducted so far have not included a static torsion test, the results of which are crucial for parts such as machine shafts, hubs, couplings, etc. Hence the idea of conducting the research in question. The samples were made in different settings relative to the machine's working platform and subjected to post-processing in two variants – by water-soaking and furnace-heating – in order to determine the influence of the orientation of the model in the manufacturing process and the type of post-processing on torsional strength. The produced samples were additionally subjected to a preliminary dimensional and shape verification due to the significant impact of the accuracy of the models in the SLS process on the operation of the above-mentioned machine parts. Based on the analysis of the test results, it was found that the highest torsional strength was determined for the furnace-heated samples. In addition, the highest mapping accuracy was found for models positioned vertically in relation to the machine's working platform.
