<p>I'm attempting to print some flexible TPE filament. But I failed to imagine TPE was this difficult to print.</p>

<p>Specs of the shop-brand filament:<br>
Red 1.75&nbsp;mm TPE (+-0.05&nbsp;mm).<br>
Hardness: 45D.<br>
Print temperature: 220-260&nbsp;&deg;C with 0-95&nbsp;&deg;C bed.</p>

<p>I'm trying to print <a href="http://www.thingiverse.com/thing:1936797" rel="nofollow noreferrer">this</a> on my original Prusa i3 MK3S with powder coated sheet with 0.20&nbsp;mm layer with PrusaSlicer 2.0.0.</p>

<p>What happens? After 3 or 4 layers, the print warps a lot and detaches from the plate. The object is 40&nbsp;mm long. The next image shows the print detaching from the build plate as well as a skirt of two layers height:</p>

<p>I've tried warmer/colder, more/less fan, faster/slower. I went down to 1&nbsp;mm<sup>3</sup>/s, which is 7&nbsp;mm/s. For reference, PLA prints 15&nbsp;mm<sup>3</sup>/s.</p>

<p>I readjusted my z-cal, and when I test print a first layer with TPE it's difficult to remove from the bed.</p>

<p>I also attempted the glue stick on smooth PEI sheet. Worked until the first few layers of infill, then it still warped.</p>

<p>Do I have bad filament with too much shrink, poor settings or is this 45D just too soft for my MK3s? </p>

<p><em>Bonus pile of failures:</em><br>

This picture is one that I could have taken. </p>\n\n<p>It has always been because I was putting too much plastic into the available space.</p>\n\n<p>This has been caused two things: overextrusion -- squirting out too much plastic for the intended layer height, and the bed being too "high" so that the gap between the nozzle and the bed is too thin.</p>\n\n<p>In both cases, too much plastic is trying to be placed in too small a volume.  The plastic has to go somewhere, and ripples follow.  Because the nozzle rubs against the adjacent lines which have already been deposited, an up-bump pushes up the nozzle on the line beside the bump, and a coherent pattern of ripples can form.</p>\n\n<p>The "bump up" is a real effect from the elasticity of the Z-axis, including all the resulting strains of twisting and lifting the nozzle.</p>\n'}, {'answer_id': 10547, 'author': 'dracotdragon', 'author_id': 17001, 'author_profile': 'https://3dprinting.stackexchange.com/users/17001', 'pm_score': 1, 'selected': False, 'text': '<p>This could be a number of things, I personally think it could be either over extrusion or an issue with one of the belts. Depending on the printer, you may need to manually go in and adjust your steps per millimeter, which you should be able to find a guide on. If that doesn\'t work, then look into belt tension adjustment. Hope this is able to help!
