</div></div></div><br>Abstract:<br><br> Desktop 3D printing has become fairly popular in the last few years,<br> and affordable printers are flooding the market. But why buy a<br> difficult to hack black box when you could spend weeks<br> sourcing/printing parts, crimping a a bunch of wires, and calibrating a<br> fully open design from the RepRap project?<br><br> Aside from the freedom that comes from building your own libre hardware<br> printer, building your own has many advantages that make the effort<br> worth it. Want dual extrusion? Triple, quadruple extrusion even? Or how<br> about pushing the limits by printing clay or icing? Perhaps you'd like<br> a tiny but super fast printer, one you could fold up and fit into a<br> backpack, or a printer with a meter of build height. With a libre<br> hardware printer, you can do all of this -- and far more affordably<br> than purchasing or modifying a closed printer platform.<br><br> This talk will cover the advantages (and disadvantages) of building a<br> libre hardware printer with a focus on the popular RepRap Prusa i3<br> family. Finding the community, selecting one of dozens of designs,<br> sourcing components, and building a printer from scratch can be a<br> harrowing experience -- this talk should provide some orientation in<br> the chaos and make the process easier.<br><br> The talk will also cover using a 3D printer with 100% Free Software on<br> GNU/Linux, from designing models (including the printer itself!) to the<br> microcontroller running the printer.<br> <br><br>Bio:<br><br> Clinton Ebadi is a kilt-wearing, cat-loving, Free Software<br> enthusiast. He's spent most of the last decade volunteering for the<br> Internet Hosting Cooperative and learning way more than anyone should<br> know about OpenAFS. After picking up an Arduino last year to make a few<br> LED strips blink, he found himself borrowing a friend's 3D printer a<br> few months later, and ended up hooked on hardware hacking.<span class="HOEnZb"><font color="#888888"><br><br></font></span></div><span class="HOEnZb"><font color="#888888"></font></span></div><span class="HOEnZb"><font color="#888888"></font></span></div></div></div>Jeremy Davis<br></div>TriLUG PR<br></div>
