Selective laser melting (SLM) using as the main manufacturing process. This is what we did when we made this sled. In a team of five we designed a high-end sled fully printed of steel. Together with steel company MF Geurtsen, we were able to get to know every detail of the SLM.
The project started with a regular shaped sled. We put this shape into SolidWorks and we used an anthropology study to see what material we could get rid of. After a lot of iterations, we had a sled that was as light and as stiff as possible.
To take our sled to the next level we focused, after having our main shape, on the lattices. Together with MF Geurtsen we came up with lattices that would make the sled 40% lighter with losing any stiffness.
Because of the size of the SLM printer we had to divide the sled in different. The different pieces could be later joined by using a heath assembly.
During the project I was the project leader. I made the planning, was responsible for the design and made most of the decisions.
Below a photo series is shown which shows in chronological order the process.
