DIY Polishing Station

prusaprinters

<p>A DIY polishing station to smoothen 3d-printed parts built using Arduino and portable humidifier.</p> <p>Note: Only tested on Polymaker's Polysmooth filament and 70% ethyl alcohol.</p> <h3>How I Designed This</h3> <p>Polymaker's Polysher in combination with Polysmooth is a revolutionary product. I wanted one.</p> <p>However, since I missed the Kickstarter campaign, I didn't want to pay higher ticket price plus I can't wait for May for the pre-orders to get shipped so I decided to make one instead.</p> <p>Having an Arduino kit lying around, I only needed to find a suitable humidifier/mister and container to build the polishing machine.</p> <p>After, weeks of waiting forcomponents, finalizing the Arduino sketch, and printing the parts, here's the result!</p> <p>As I have several parts left over from previous projects and been sourcing out most of the parts from China, my total cost for this build was a little over $50.

This ensures that mist coming from humidifier will easily reach the platform. Also, being in the front (rather than the back) makes the mist more visible while polishing.</strong></p> <h3>Gallery</h3> <p><strong>Bulbasaur model printed using PolySmooth (Snow White) with 1.6mm wall thickness, polished for 35mins using 70% ethyl alcohol.</strong></p> <p><strong>Before and after polishing: Charmander model printed using PolySmooth (Snow White) with 2.0mm wall thickness, polished for 45mins using 70% ethyl alcohol.</strong></p> <h3>User's Guide v1.0</h3> <p><strong>PARTS OF THE POLISHING STATION</strong> <strong>IMPORTANT!</strong> <strong>INTERACTING WITH THE POLISHING STATION</strong></p> <p>The polishing station is equipped with a control panel with a LCD and rotating push button to allow the user to interact with the machine.</p> <p>The LCD will show different information and status depending on which mode the machine is on.</p> <p>The rotating push button allows the user to send inputs to the machine and/or trigger various actions. There are three (3) ways to operate the rotating button:</p> <p>1.<em>Click</em> - quick push and release of the rotating button 2.<em>Hold</em> - pushing the rotating button and waiting for two (2) seconds before releasing 3.<em>Rotate</em> - this is accomplished by rotating the button either clockwise or counterclockwise</p> <p><strong>OPERATING MODES</strong></p> <p>The polishing station has three (3) modes:</p> <ol> <li>Ready/idle mode</li> <li>Setup mode</li> <li>Polishing mode</li> </ol> <p>The machine starts in<em>Idle</em> mode upon turning on.</p> <p><strong>READY MODE</strong></p> <p><strong>SETUP MODE</strong></p> <p><strong>POLISHING MODE</strong></p> Category: Other
