This is a one of a kind 3D printed lamp developed from a MRI scan of a brain and converted that into a workable model. At that point, we had a model that could be transformed in ZBrush. Creating topography that flows, grows and shinks with the brain’s rhythm and concavity was a design objective. After several revisions the end result is radiant. The print out seen in our photos is an FDM print that took nearly 50 hours per hemisphere yet only weighed 200g each. The model provided is ideal for an SLS machine, no support removal, and we are looking forward to seeing this made on the Sinterit Lisa.

Hello Sinterit_3D, The main challenge we had is that each hemisphere of the brain required a lot of support material. Support material is not always a huge issue; however, the mesh of the model contains very fine details. While removing the support material, some cosmetic damage was inevitable. In the pictures provided you can see the model in Zbrush, sliced preview, and finished print from below the glass. The model in Zbrush is very detailed; however, using the FDM machine it is nearly impossible to replicate precisely. The slice preview provides a break-down of print time (infill, retraction, supports, walls, and travel time to name a few). The last image of the FDM print from below the glass clearly shows the amount of support needed to print this object. Not ideal. A SLS machine could accomplish a complex print like this without the need for manual support removal which caused damage to the final product. The entire mesh could have remained intact having been done on a SLS machine. A SLS print of this model could produce a higher quality finish with a greater level of accuracy. In addition, post-processing could be greatly decreased compared to the FDM print. We feel SLS printers provide important advantages over FDM when confronted with design challenges like the brain lamp. Over all, a more professional product is made in what could be a more efficient pipeline from conception to delivery.
