Is there any commercial supplier of 3D printed parts made from acrylic (PMMA)?
While I don't know of PMMA as a standard offering, I do know that a lot of the smaller entities will gladly accommodate custom requirements for the right price and an understanding that results may be inferior to their tried and true.
My recommendation is to google &quot;3D Printing Service&quot; and find what's local.  Local will hopefully mean you don't have to wait for a shipment to review the quality.
