Sammanfattning
The concept of Additive manufacturing (AM) was introduced already in the 1970’s as mentioned in (Wholers et al., 2016) and the first commercial system were introduced in the late 1980’s, this type of manufacturing is relatively new. When using AM technology, the components are manufactured by adding the material layer-by-layer and selectively where needed. Plastic materials were first used and since then, several AM-technologies has been launched with a larger selection of materials. This bachelor’s thesis was made at Research Institutes of Sweden (RISE) IVF AB. The main purpose of the thesis was to set the base for creating a design guideline for one of the additive manufacturing technologies, specifically Metal Binder Jetting. Literature review was used as base for the information around the technology and existing guidelines, but we have also performed interviews as well as discussed directly with one machine and service provider, Digital Metal AB. Most of the information as found with respect to the design guidelines were of general character. The information is intended to be compiled into a guide with the initial purpose of designers with low or limited knowledge of design for MBJ. Therefore, it was decided to print artifacts with help from Digital Metal AB to be able to set the base for what is viable and not, connected to the design rules. The printed parts were evaluated with manual inspections.
