Omkonstruktion av vapenfäste till additiv tillverkning

Sammanfattning: The thesis project has been carried out in collaboration with Saab training and simulation in Huskvarna, which manufactures military training products. The aim of the project was to investigate the possibility of using additive manufacturing as the method for future manufacturing for the small arms transmitter bracket (SAT-bracket, a bracket for gun) to reduce lead time, cost and weight. A physical product has been developed through the Selective Laser Melting technique (SLM), where the least possible amount of support structures has been achieved for the selected build orientation. To be able to optimize the design with the help of lattice structures, knowledge of the technology has been acquired through information searched on scientific texts and websites. Identification of strengths and weaknesses in the development process and the possibility of using a more favorable material for the application were documented to be evaluated against a traditionally manufactured component. The final designs have been modeled using two different design methods, both in which had reduced the weight between 28-44% where the stiffness is in the likes of the reference product. The conclusion drawn from the work is that additive manufacturing is a manufacturing method   that for the SAT-bracket is a favorable alternative for smaller production volume.
