Mini Laser Engraver Upgrade Parts

prusaprinters

<p>These are the 3D printed part designs that go with my Instructable, <a href="http://www.instructables.com/id/Making-Your-Mini-Laser-Engraver-Safer-and-Better">Making Your Mini Laser Engraver Safer And Better</a>. They are designed to be used with any of the SuperCarver-style "Laser Engraver Printer Cutter Carver DIY Engraving Machine" units commonly sold for between $80 and $150, and I have applied them to a 1000mW @ 405nm unit branded HTPOW. See the after and before photos above. <a href="https://youtu.be/CoWR9j_RGYg">Here</a> is a video from the webcam I placed inside the engraver -- it is not sped-up; this is the actual engrave speed.</p> <p>These machines have the potential to very quickly cause significant harm. I'm not an expert in the law, nor in laser safety; I'm just a maker who sees the potential, both good and bad, of these little engravers.<strong>You bear all responsibility for safe configuration and operation of your laser</strong>. I'm just describing what I did to my machine in an attempt to<em>reduce</em> the risk and improve functionality.</p> <h3>Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>MakerGear</p> <p class="detail-setting printer"><strong>Printer: </strong> <div><p>M2</p></div> <p><strong>Rafts:</strong></p> <p>No</p> <p class="detail-setting supports"><strong>Supports: </strong> <div><p>No</p></div> <p><strong>Resolution:</strong></p> <p>0.25mm</p> <p class="detail-setting infill"><strong>Infill: </strong> <div><p>25%</p></div> <p><strong>Notes:</strong></p> <p>These parts are easy to print, but material choice is very important.<strong>Print them in PLA</strong>. Why? PLA behaves much better than most plastics when hit by a laser; especially avoid any chlorinated plastics, but also avoid ABS because the gas produced if it gets hit by the laser is pretty nasty. The color of the material also matters; enclosure parts need to be opaque to the laser light, and the jigs should be made of a color that minimizes scattering of the laser light.</p> <h3>Post-Printing</h3> <p>Read my Instructable to understand how these 3D-printed parts are intended to be used; also read other materials so that you can understand the dangers and safely operate your laser.<strong>Avoid the temptation to try things first and read instructions after a serious problem has surfaced:</strong><em>I didn't even plug-in my laser's power supply until after I had built an enclosure for the unit</em>.</p> <h3>How I Designed This</h3> <p>These parts were all designed using OpenSCAD. I might post a Customizer version once I'm sure the design will not change for a while -- for example, I'm still looking at alternative methods to make the vent filtering more effective.</p> </p></p></p> Category: Parts
