Welcome to EDSGN 497J Open-Source 3D Printing course. We cover the topic of creating physical objects by converting a part-data file to machine language G-Code, then using a self REPlicating RAPid prototyping machine - REPRAP - to extrude melted polylactic acid through a nozzle, the movement of which is controlled by the G-code instructions. The source of the part-data for this course is mainly the internet, where related sites list part files to be downloaded free of charge. Users obtain the part files, inspect for errors, convert the .stl (standard tessellation language) file to G-code and create their part on the REPRAP machine. .stl files are those which are divided into slices representing the layers that the parts are built up from. The following is a presentation of a general introduction to Additive Manufacturing:
