Red Red Wine Plexiglass 2423

I have tested a Mini VAT resin with a 3mm thick sample ( 2423 ) red transparent
acrylic plexiglass piece provided by a local company and the results are only
mediocre.

It seems to block some, but not all of the UV and Near Visible.
Comparing to a Lee Filter sampler "Bloody Red", the 2423 allowed a 0.5mm resin
slice to polymerize in 2~5 minute exposure, while when it was placed over the Lee Filter it did not
exhibit any polymerization for 20 min.

This is what it looked like in the mini VAT. A tribute to the RepRap crowd for inspiration and information.

I would assume (have to confirm) it will be safe if used with an incandescent or florescent bulb. Do not expect the red 2423 to stop the UV from sunlight or other sources from ruining a VAT full of resin and the print.
