Funnel with filter. (Vase mode)

prusaprinters

<p><strong>Description:</strong></p><p>These funnel were created while I was making other vasemode projects. I needed a filtered funnel while I waited for a metal one to arrive. I wanted something quick, so I created these two. Small one's opening is at 10mm with the filter holes being about 1mm at their widest. The other listed funnel has a 20mm opening and the filter holes are 3mm at their widest. I used this to pour alcohol back in the container after cleaning resin print. Be mindful of the material you make it with compared to it's application. Also, wear your P.P.E. :)&nbsp;</p><p><strong>Printing:</strong></p><p><strong>PRINT IN VASE MODE!!!!!!!</strong></p><p>This was made to solely be printed in vase mode, so save yourself some filament and print it in such.</p><p>Clean your print bed . This has a small layer that touches the bed, so don't let a finger print ruin your print.</p><p>I printed the small example in FormFutura white rPLA at 0.15MM with a .4 nozzle, took no time at all. I printed the large example in FormFutura white rPLA at 0.20MM with a .4 nozzle, took about 2 hours. If you're a gambling type of person I'm sure you could speed those times up.</p><p>I wouldn't scale the small one down at all. However you can scale the regular one down to about 50% in tests before the filter is no longer a filter.</p><p>&nbsp;</p><p><strong>Chemicals!</strong></p><p>I made my examples pretty much as a test and a single use.(Wasteful I know) PLA is only really good against water. So you don't hurt yourself or have an accident here's a table of chemical resistances with filaments:</p><figure class="table"><table><tbody><tr><td>PP</td><td>Most chemicals (except acetone and fluorinated/chlorinated chemicals)</td></tr><tr><td>PET(g) / CPE(+)</td><td>Alcohols (EtOH, IPA), water, acids and bases</td></tr><tr><td>Nylon</td><td>IPA, Solvents (acetone, glycerol)</td></tr><tr><td>ABS</td><td>Water, some acids and bases, alcohols</td></tr><tr><td>TPU</td><td>Water (salts), glycol and fuels</td></tr><tr><td>PC</td><td>Water and alcohols</td></tr><tr><td>PLA / Tough PLA</td><td>Water</td></tr><tr><td>PVDF</td><td>Solvents (chlorinated, aliphatic, aromatic), strong acids, weak bases, halogens, strong oxidants</td></tr></tbody></table></figure><p>If you like reading published papers; go here: <a href="https://www.sciencedirect.com/science/article/abs/pii/S2214860418303476">https://www.sciencedirect.com/science/article/abs/pii/S2214860418303476</a></p><p>&nbsp;</p><p>Happy printing and wear you P.P.E.!</p>
