Layer Height Demonstration Plaque

thingiverse

I created this plaque to demonstrate how different layer heights affect detailed prints. To achieve this, I adapted a modified version of JulPal's allosaurus claw file. Simply print the claws at .1032, .2064, and .3096, then glue them onto the board. I used 20% infill for the two higher resolutions to ensure top layers didn't sag. The .3096 print was roughly 15% infilled. To create the laser-cut part, I utilized a 50w Epilog Zing on 1/8" MDF. I etched at full power and 50% speed to achieve a nice pit for the claws, then secured them with E6000. Print Settings: Printer Brand: Printrbot Printer: Simple White Rafts: No Supports: No Resolution: .1032, .2064, .3096 Infill: 15%, 15%, 20% Notes: Due to imperial z-threads on my Printrbot Simple, I used the full four-digit layer heights. These parts are intended for educational purposes, so I'm explicit about those values. Design Process: I began with the original Allosaurus claw and used Meshmixer to cut half of it away using a plane tool. Then, I exported the flat base as an SVG file, ready for use in Inkscape. I expanded the outline of the claw, added text, and created cut lines within Inkscape.
