Phone case for a Samsung Galaxy S3. These are printed with a laser sintered plastic and should be sealed for best longevity. Basically they are porous by nature. I use Future floor shine by Pledge http://www.walmart.com/ip/Future-Wood-Floor-Cleaner/14894114 Any sealer for plastic will work. These are printed in a hard plastic with very tight tolerances and might need a very thin layer of silicone to completely eliminate shifting.
This was my sizing print for the Galaxy S3, the picture show the first print and I have fixed the camera to center the hole and the same with the one side button. It is good to go now
