Ok so I’ve looked around and I’m not sure if what I’m wanting to do is possible but I’ll ask here to see if anyone has done something like this. I will be making something out of 0.25" HDPE and I’d prefer it to have a matte finish when it is completed. To accomplish this in the past, I’ve sanded the HDPE by hand. This is quite tedious and was wondering if I could get some sort of buffing/sanding wheel (maybe for a Dremel?) and rig it to work in the X-Carve by “engraving” the entire piece at a tested depth so it knocks the finish down a bit. Thoughts?
abrasive nylon brushes come to mind. such as NamPower. unsure if there’s a readily available option that’s suitable on the Xcarve
perhaps experiment with small nylon brush drill attachments?
otherwise i’d suggest picking up a Harbor Freight sandblaster for matte finishes
I’m not sure you’re going to end up with the finish you’re after. Since the toolpath is going to follow well-defined, well, paths, for the most part, you’re still going to end up with rows and circles along the straight lines and corners of the toolpath.
