So, a while back I’d asked if there was any Delrin or acetal plastic available to play with. I finally got a chance to play with some. From experience on other lasers I know that I usually have to cut it a bit slower than I do acrylic so I took a calculated guess to start at and it actually worked the first try. I was using some 1/8 inch white acetal that I’ve used on other machines. It cuts like melting candle wax really and though you don’t get really crisp edges like you do with acrylic, it’s much more forgiving to stress and flexing. It’s an interesting material, similar in feel to Teflon. Like Teflon, you can’t really paint it or anything and I’ve only found sheets in either black or white. I’ve not had any luck dying it colors. Being so smooth it would probably be really good for gears or similar mechanical pieces. My favorite thing to use it for these days though is belt buckles
I knew what my first project should be with it so I had a design all lined up for it. the detail came out as I’d hoped and there was only a small candle like flame trailing the cut as it went along. The sides where the material was being cut very thin curled up under the heat, but didn’t stick to or damage the piece I was making.
the piece I cut out though about the same thickness didn’t have the same issue.
I’d hoped to find some 1 1/2" webbing in this color, but haven’t yet.
But luckily it doesn’t look bad in blue either
I’ll be doing some more tests with black as well as thicker to see how they work, but I’m pretty darn happy with how this worked out.
For those interested, the design is simple and comfortable and I borrowed it from the excellent folks over at www.grip6.com. They have some beautiful anodized aluminum buckles that are blank canvas’ waiting to be etched.
