Mini Paint Pots in TPU

prusaprinters

<p>When i painted my <a href="https://www.prusaprinters.org/prints/90614-santa-with-thumb-up">Santa</a>, i thought sealable pots for the acrylic would be nice. So i quickly designed them, printed them in DasFilament TPU and quickly realized… bad idea.&nbsp;</p><p>The first prints where full of holes. The TPU was too moist. I did keep it in container with silica, but that seemed to be not enough. I did not think TPU was that hydrophil. It kept popping in the nozzle all the time.&nbsp;</p><p><img src="https://media.prusaprinters.org/media/prints/91603/rich_content/41872510-510b-4e82-bf66-494531651d7c/img_20211207_111649.jpg#%7B%22uuid%22%3A%22ef386950-9e80-4320-8691-b806c523583c%22%2C%22w%22%3A4000%2C%22h%22%3A3000%7D">So i tried my hands on drying the TPU. I found the best result was to cut a good enough length of the spool, throw it in the oven at 80°C for 2-3h and the let it sit in a small bag with a good amout of silica for the weekend. And print directly out of this bag. The results are really nice this way.</p><figure class="image"><img src="https://media.prusaprinters.org/media/prints/91603/rich_content/dfccf47d-d9a5-4fbb-9aea-2a43e96656b3/img_20211207_111559.jpg#%7B%22uuid%22%3A%2239e87d92-ead6-42b7-ad92-2ea9fbf5b528%22%2C%22w%22%3A4000%2C%22h%22%3A3000%7D"></figure><p>There are two versions, a thick one for 0.8mm nozzles and the other for 0.4mm nozzle. But thick can also be printed in 0.4 of course.&nbsp;</p><p>I disabled retraction to reduce the posibility of a leak.&nbsp;</p>
