Mini Laser Engraver Upgrade Parts

thingiverse

These are the 3D printed part designs that accompany my Instructable on making your mini laser engraver safer and better equipped. They have been designed with compatibility in mind for any of the SuperCarver-style "Laser Engraver Printer Cutter Carver DIY Engraving Machine" units typically sold at a price range between $80 and $150, and I have successfully integrated them into a 1000mW @ 405nm unit bearing the HTPOW brand. You can view the before and after photos provided above. Here's a video captured by the webcam installed inside the engraver - it is not speeded up; this is the actual engrave speed. These machines have the potential to inflict significant harm in a very short amount of time. I am not an expert in law or laser safety, but rather a maker who has observed both the positive and negative aspects of these small engravers. You are solely responsible for ensuring safe configuration and operation of your laser. My intention is simply to describe what I have done to my machine with the goal of reducing risk and enhancing functionality. Print Settings Printer Brand: MakerGear Printer: M2 Rafts: No Supports: No Resolution: 0.25mm Infill: 25% Notes: These parts are relatively easy to print, but material selection is crucial. Print them in PLA because it behaves much better than most plastics when exposed to laser light; specifically, avoid any chlorinated plastics and also steer clear of ABS due to the hazardous gas produced if it gets hit by the laser. The color of the material also plays a significant role; enclosure parts must be opaque to laser light, while jigs should be made from a color that minimizes scattering of laser light. Post-Printing Read my Instructable to understand how these 3D-printed parts are intended to be used; also read other materials so you can grasp the dangers and safely operate your laser. Resist the temptation to try things out first and then read instructions after a serious problem has arisen: I didn't even plug in my laser's power supply until after I had built an enclosure for the unit. How I Designed This These parts were all designed using OpenSCAD. I may post a Customizer version once I'm confident that the design will not change for some time - for example, I am still exploring alternative methods to improve vent filtering effectiveness.
