Experimental Laser Engraved Circuit Board Leather Belt

I’ve been wanting to laser engrave a belt. Although lasered leather can be stinky, it usually turns out beautiful! I measured an existing belt that I owned to get an idea of the length I would need. I estimated that I would need to have the belt be at least 38" and about 1.5" tall. Conveniently, I found leather strips pre cut online! I considered recycling a circuit board, embedding it in resin, making a wild belt buckle, but I wanted this belt to be a practical, everyday wear kind of belt. So I ordered a simple gun metal belt buckle.

Next, I had to design my belt. I knew I wanted to do something with circuits, because I’m nerdy like that. I thought it would be a fun spin off of the typical leather belts with names engraved, but mine would be the futuristic, technology-loving version! I went to my favorite site for free fonts, dafont.com. After testing out a few, I settled on ‘Circuit Mage’. I felt like it would be the easiest to incorporate into an existing circuit board pattern. I realize it’s not a real circuit board pattern, but it is a pretty one! I love Inkscape and use it for designing everything; embroidery files, 3D files, even the circuit boards that I CNC!

I am fortunate in that I work at a Fab Lab. My Fab Lab has two CO2 laser cutters, an Epilog and Universal. I chose to use the 40W Universal laser for the engraving because it has the largest bed, 32 x 18". The experimental part of this project would be to create an Inkscape/SVG file for my 38" belt, and then split up the file into two separate laser files. I would have to pick up & move the leather to get the rest of the design engraved. I knew this would be difficult, so I experimented with a strip of thin chip board.

I only matched it up with the top of my design, hoping the rest would match just as evenly!
It took quite a few tries to get things aligned.

In my Inkscape file, I measured everything to exactly fit onto the bed. What I hadn’t accounted for was how the leather would be out of focus when it draped over the edge of the laser’s bed! I used the snapping guides in Inkscape to align my design, but I still had to slightly shift my file over a few mm.

This area of the belt is lighter etched than everything else, because it was slightly out of focus!
The rest of the design turned out gorgeous and even! Laser engraved with 40% power, 100 speed.
Forest Green Leather dye time!

I love using these refillable markers when I apply dye to leather items. It keeps me from dripping dye everywhere, and doesn’t leave fibers on the surface!

The color came out a little darker than expected, but I like it, the pattern is more subtle, less loud and busy! I shaved off some of the leather in the fold, so it wouldn’t be so bulky. I used waxed thread to stitch the fold down.

I still need to burnish the edges and seal the inner leather, but so far I am really pleased with how it turned out. I look forward to lasering more leather projects soon!
