I have recently ordered a part in the transparent material from shapeways. I needed it to be transparent, so have been sanding it (intending to polish) As i sanded, some marks have become apparent in the material. i think they are like bubbles, where the different layers of materials have not fused properly. I have included an image.
I am wondering if anyone else has encountered this problem, and might know if it's possible to use some sort of resin to make the fill the gaps/ make them invisible?
I'd appreciate any help
