Hi everyone,
we had a couple of the loading stations for the autoloader (Krios, Arctica) crack and leak at the bottom. FEI told us that they were not repairable and would cost 15k a piece. I tried to be hip and 3D print the parts first but in my experience they would all crack and leak after a couple of cooling cycles. So, I made a 3D model for CNC milling and these work as good as the original parts. We used the company called FATHOM (https://studiofathom.com/) here in Oakland and within about 10 days they can mill these things out for about $400 a piece. We tried aluminum, teflon and delrin. It seems like the original material is Delrin and is probably the best choice. Aluminum is definitely not optimal as it takes a while to cool and frosts over quickly. Teflon doesn't deform as much as Delrin but other than that seems similar. Here is the link to the zip archive of the 3D model in three different file formats .igs, .stp, .ipt. The first two you can give to any 3D milling service and they will be able to make the part. The .ipt is the Autodesk Inventor 3D file, so, you can open and play/modify it. Autodesk Inventor 3D is free (as I think are all the Autodesk products) for students/.edu addresses. I also include a pdf file with instructions on how to disassemble the station.
