I have been working with a 3D printer since 2012. My first 3D printer, a Prusa-Mendel, was homemade because there were no ready-made devices available at the time. Later I made the Prusa I3 model. In 2020 I bought a Renkforce 100 and in 2023 the Bambulab X1 carbon. I have been teaching Solid Edge for over 15 years and Sketchup make for 10 years.
