Many of us rarely use PLA and prefer ABS. We can buy ABS at our local stores or online. ABS is inexpensive and very durable. I think your Polysher filament may not be as durable if it dissolves with alcohol.
Colorfabb XT is a filament that is superior to PLA or ABS in many ways. Some people are beginning to use it exclusively. It does not warp like ABS. has a very nice finish and is durable.
If your machine was larger and could use acetone it would be great. But, I think acetone would damage its clear plastic cover.
I like the Polysher concept, I do. I would like to see the next version be larger and work with ABS or XT.
