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.

Printed on a Voron 2.4. I enlarged it a bit and added a stainless steel & oak base.

Best and complicated model ever printed. Here are my settings Default size layer height - 0.14 support - Tree Support Printer - prusa mk3s (self made clone)
