Title: filament holder TPU
Post by: delaire on February 11, 2017, 05:50:22 PM

since i make my first prints with TPU i figured out a underextrude. i think that may the standard filament holder already makes not easy to rotate the spool. has anyone a good solution as alternative?

There are a number of printable spool holders that use inexpensive skateboard bearings to reduce rolling friction. Some sit on the bench next to the printer while others mount on the wall. There might even be one that mounts on your Zortrax, although I haven't seen it. They come in two basic designs, ones where bearings support a spindle on which the spool turns and others where the spool sits on rollers having bearings in their center. If building isn't your thing, shop Amazon or other places that cater to 3d printing.

Good luck.

For stretchy filaments I recommend mounting the spool higher than the printer so that the filament only has to go "down", not "up and then down"; this will reduce pull and stretch.

Also, for TPU/TPE/TPA I recommend reducing printing speed with the latest version of Raftaway.

Here are two ideas: one ugly, one nice. Both work :)
