Etching designs into denim with a laser cutter

JeansEtchLaser

Finding new uses for your tools and equipment can be very exciting. [Foamy] wrote in to tell us about a blog post by [qbotics] that demonstrates etching designs into denim with a laser cutter. What a cool unexpected use for a laser cutter!

According to the Epilog laser cutter’s website, “we have engraved everything from denim to acrylic with fantastic results”. This inspired the author of “Science with denim” to try engraving jeans. After some experimentation,  [qbotics] found that setting the 75W laser cutter to 15% power at 100% speed worked best. The results are quite impressive; the engraved pattern looks like naturally faded jeans. Amazing.

In the past, we have seen lasers engrave everything from calculators to wood. We would be curious to see if some of the DIY laser cutters could engrave denim as well. Give it a try and tell us about it!

Just in case you didn’t know how awesome laser cutters really are

[Alex] got his hands on an Epiloge laser cutter the easy way — the company he works for bought one. We’re sure he’s not trying to rub it in, but he really does make the tool look and sound cool in the post he wrote purely to show off the new toy hardware.

This model is a CO2 laser and it’s capable of etching and cutting a variety of materials. It does so with a 1200 DPI resolution at 0.005 pitch. The samples of engraved text and images show the clean lines and shapes this type of accuracy can achieve. The most stunning example is a piece of anodized aluminum which ends up showing some fantastic contrast that would make perfect face plates for project enclosures. Then there’s the cutting feature which is responsible for the gear demo seen above. We were surprised to hear that it will cut through acrylic but not polycarbonate.

After the break we’ve embedded [Alex's] video. The camera is focused on the cutter as it engraves some lettering, then cuts out a gear. During the process he discusses what he’s learned about the device, sharing some interesting tidbits along the way.

We’re hoping to see some cool stuff like this from [Grenadier] who recently won a similar 40 Watt CO2 laser from Full Spectrum.

1 Watt laser engraver

This laser engraver was built using printer parts, a CD-ROM carriage, and some homebrew electronic boards. The laser diode is a 1-Watt model similar to what we saw used as a weak laser cutter back in August. When the width of the material changes the focus of the laser is affected so the diode was mounted on a CD-ROM carriage (in the Z axis) for easy adjustment. The X and Y axes are made using parts from Epson Stylus 800 and Epson Stylus Color II printers. After the break we’ve embedded a video of the machine engraving some wood using EMC2 software on an Ubuntu box. It also boasts the ability to cut paper and some plastic but it can’t compare in power to a CO2-based unit.

Hackaday links: Sunday January 24

Everyone Remembers Free day right? [The Ideanator's] Bus Pirate came in such a nice red box – he decided to make it his permanent case.

[Chico] is in the middle of making a CNC, but decided to make some music with the steppers in the mean time.

What looks like an old wooden box is actually [Ludvig's] super sweet retro arcade cabinet. Complete with a giant emergency stop red button.

Who says Legos are dead? [Carl] used them to create a simple and cheap diffraction grating projector. Including video!

[Torchris] used an Ethernet shield exactly as it was designed, sending data over Ethernet. Still a nice hack for those needing help working with Ethernet shields and Arduino.

Finally [Robert] let us know about a friends Arduino Binary Clock. But we think his elegant use of tape and a sand blaster to engrave glass is cooler.
