Surface smoother

Hello,

3D-printer: http://www.voxeljet.de/en/systems/3d-druckervx1000/

I am printing with the material PMMA. The surface is grainy and feels rough.

Is it possible to get a smoother surface with a spray or wax?

Thank you in advance!

I believe you can use Aceton on PMMA similar to ABS by rubbing over it with a Aceton-damp cloth or vapor bathing.
