Creality Hot End Model

<p>Why would you want to have a plastic model of a hot end?</p> <p>I wanted to have a model of a 3D-printer hot end for educational purposes in our Makerspace. I found the <a href="https://www.thingiverse.com/thing:2920805">CR-10 Hot End Model by intoxikated</a>, printed it and looked at it.</p> <h3>Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Wanhao</p> <p class="detail-setting printer"><strong>Printer: </strong> <div><p>Wanhao Duplicator i3 V2</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>0.2 mm</p> <p class="detail-setting infill"><strong>Infill: </strong> <div><p>20%</p></div> <p><strong>Filament:</strong> Clas Ohlson PLA gray</p> <p><br/> <p class="detail-setting notes"><strong>Notes: </strong></p> </p><div><p>I printed at 300% with all separate part lying with the cross-section cut side flat on the glass baed of my printer to give them a nice shine.</p></div> How I Designed This =================== <p><strong>Design process</strong></p> <div><p>I took the printed model and compared it to the real thing. What I was looking for was to show the inner workings of the hot end - but there was a lack of detail in the existing model.</p> So I threw away everything and as usual started in OpenSCAD. <p>The final model consists of 5 parts which can be printed in place or separately: the heatsink, the insert, the heater block, the nozzle and the lower end of the bowden tube.</p> <p>Printing a cross section is enabled by default.</p> </div></p></p></p> Category: Engineering
