Leaves, MC Escher’s Rippled Surface and some sci-fi just for fun
Using a laser cutter to add physical presence to 2D artworks can be really effective, as these recent explorations from Maxime Beauchemin show. Having kicked things off with a rather elegant laser etched ATAT walker, he then moved on to more everyday ephemeral visions.
Pictured above is an acrylic replication of MC Escher’s iconic Rippled Surface print, where Maxime faithfully recreates the layered illusion of water surface, reflected trees and rippled distortion.
Turning to laser cut wood for another project, the delicate structure of a decaying leaf skeleton is revealed. (more…)
Space saving portable design takes laser cutting on the road
Here is another interesting DIY laser cutter project, this time featuring a novel departure from the standard construction we are used to seeing.
Instead of running within a constrained space, the compact laser cutter has an arm that swings out in a format reminiscent of the RepRap 3D printer.
When the laser cutter is in use the arm opens up to 90 degrees perpendicular to the box and the laser head runs along it.
The main structural elements are made from aluminium extrusions, and there are a few custom CNC milled and 3D printed components to fill in the gaps and connect other off-the-shelf parts.
This looks to be a novel way to build a laser cutter that you can take on the road with you. No more heavy equipment fixed in place in the workshop… just be careful not to set it up on your grandma’s favourite coffee table!

Running interesting laser cutter experiments is one of the things that Just Add Sharks does best. In this exploration, they have addressed the question of how to break away from the mortice and tenon joints that have become so familiar in laser cut projects.
By creating a laser cut jig that holds the material at a specific angle, they were able to cut edges that can fit together in a manner that is clean and precise. No more stepped blocks and slots! Here is what the jig looks like:
Much easier to achieve than modifying the axis of the laser cutter itself, this jig provides a firm support to a pre-cut panel, and does not require any other machine modifications. The angle of the cut can be controlled by altering the vertical supports.
“Manually changing the angles like this is tiresome so the next sensible upgrade would be to build an ‘any angle, any material thickness’ jig for the same purpose, but that is a job for another day.”
The Just Add Sharks blog has an overview by Martin Raynsford that talks through a few of the considerations that led to the first successful cut. Having proven that it can be done with standard perpendicular joints, they adjusted a few specs on the jig to produce a icosahedron, pictured below.
Giving 3D form to desktop cutting projects. Next stop, to the laser cutter!
Already well established as the gold standard for bringing super-simple 3D construction to the DIY masses, Autodesk 123D has announced an exciting partnership that goes one step further. They’ve teamed up with Cricut, the guys responsible for desktop electronic cutting machines that induce equal measures of desire and envy amongst Makers and Crafters.
The collaboration features a new series of easy-to-assemble 3D DIY projects including dinosaurs, rocket ships, creatures and homewares that are all geared towards owners of the Cricut machines.
Now, while this is a clearly targeted partnership that brings the clever slicing technology of 123D Make to users in the Cricut community, it is also a welcome reminder of the resources that are readily available and can be easily incorporated into your laser cutting workflow. (more…)
L-CHEAPO conversion kit brings laser cutting to the masses
Imagine turning a desktop 3D printer into a laser cutter without compromising its printing capabilities. That’s what Matteo Borri from Robots Everywhere has done, and the L-CHEAPO laser cutter attachment is now the focus of a wildly successful Indiegogo campaign.
Capable of cutting 3/16″ wood and 1/4″ acrylic on any hobby grade 3D printer or CNC mill, this clever little attachment runs off the existing machine’s power supply and software environment. Once the attachment is set up and configured, in a matter of minutes you can swap back and forth from laser cutter to 3D printer functionality.
“you can switch from laser to printer mode and vice versa in less than two minutes, with no tools”
Why would you want to do this? For one thing, laser cut parts tend to be much tougher than the thermoplastics used in 3D printers. This means the scope of making possibilities is significantly widened, all from the one machine.
Matteo is looking out for the little guys with this project, with the goal of making laser cutting accessible to those who might otherwise be hindered by the substantial initial investment that is traditionally associated with purchasing a laser cutter.
“I hope that this allows high school shop classes, small universities and local hackerspaces to be able to work with a wider variety of materials and techniques”
He also promises that there are larger, more powerful lasers in the works. It will be interesting to see what the big brother to L-CHEAPO is capable of.
The 3D printed component is available to download fromThingiverseand you can head toIndiegogofor further info and project updates.
Here’s a little extra, just for fun. Proving that he is serious about his DIY laser cutting prowess, Matteo uploaded this geekily amusing clip of the Tetris theme song, as played by an L-CHEAPO laser cutter in action.
