It was created by the printer of the FDM system.
Using the transparency of ABS filament, I tried an experiment of transparent modeling.
To increase the temperature of the head and the bed, it was created slowly.
After, was thin a layer as possible. (This is 0.01mm)
It is hard to understand in the photograph, it was completed in a state in which the transparent without out turbidity.
However, since the higher the temperature of the head and the bed, modeling itself I have sagging.
Since the filament is transparent cloudy little, it is clear and transparent could not be expected.
