Casting Feeder and Vent for lost PLA

prusaprinters

<p>This is a quick feeder and vent setup I made for lost PLA casting. &nbsp;For me, I print these, attach them to a 3d printed model I want to print. &nbsp;Then coat it with joint compound, let that dry. &nbsp;Encase it in sand with sodium silicate. &nbsp;Let that harden. &nbsp;Then pour in molten aluminum. &nbsp;The aluminum melts/burns out the PLA, leaving a cast object. &nbsp;I thought others might be able to use these. &nbsp;You can print multiple of the vent and attach them to make longer feeders/vents.</p><p>For an example of this casting process watch this video put together by someone much better than I at it. ;)<br>&nbsp;</p><figure class="media"><oembed url="https://www.youtube.com/watch?v=YKeImuJpxow"></oembed></figure><p>Enjoy!</p>
