Mekaniska egenskaper hos 3D- printade material och utveckling av en förbättrad skrivarteknologi : Studie av materialegenskaper och maskinutveckling

This bachelor thesis presents the design and construction of a modified 3D-printer, developed to accommodate a pelletbased extruder. The print quality of the new system will be evaluated, and the performance of the machine will be assessed. This all will be performed in combination with the comprehensive analysis of various polymer materials and their mechanical properties when 3D-printed. This project was conducted in collaboration with R.A.P.S AB in Landskrona, with the objective of developing a printer equipped with new innovative technology capable of constructing geometry with pelletbased material. The material testing is an extension to this by comparing the different mechanical properties when printed in different standards. The project has focus on the work process with design, construction, and testing. It will go over results, setbacks and why different choices were made. It will go over how different limitations have affected the project and how those have been overcome. During this whole work process, standards like ISO 527 have been followed and the vast knowledge base of the 3D-printing community as well as expert opinions.
