UHMWPE - Black
Polycarbonate - White

Ran a little mini GB of UHMWPE plates with friends. Sound-wise it is definitely deeper than both poly and POM, but the malleable nature of the material ever-so-slightly dampens the brighter "pops" that you'd get with those plates. Feel-wise it is more-or-less identical to POM.

For a rough comparison with a similar PC build:

*Order was done through Xometry. With default machining tolerances (standard) and standard QC, an order of 10 units came out to be about $36/plate (including shipping via FedEx from China to US). Plates did come with scratches and the cutouts were not deburred properly, perhaps due to the nature of the material.
