I was asked by a friend to print some badge's for the valve covers of his new ride. I have already sent one set down to ChromeTech that got rejected for porosity and roughness. They were just a straight WSF (sintered nylon) print with no sealing or polishing. I now have the new revised parts in hand that are polished alumide. Alumide is also a laser sintered nylon, however, it has aluminum in suspension to better handle heat. Alumide's heat capability is roughly twice that of WSF.
The one in back is one I raised from a photo of an Ariel Atom that I want to stick on the back of my Touareg. OK, from a different thread I know that Pledge "Future" is the sealer I should be using and these parts were ordered polished and are much smoother than the first generation. I am not concerned about those issues, the issue that has me concerned is the obvious layering of the rings that occur in both badge prints. I had modeled them on an arc and that may be the "my bad" on this issue. Anybody have an opinion on if I should try to fill it and sand smooth? I have chromed many full sized bumpers back in the day and you just took them in and they made them right. I doubt that ChromeTech is going to any effort to make these right as there is no money in it for them. You can feel the ribs with your hand, but, they are very slight after the polishing (bombardment with plastic pellets)
