I’ve been trying to print TPU for a while now and it did not work on my Ender 3 v2 with a bowden setup since the filament is too elastic (which is the end goal). Also, it jammed in the extruder’s gears of the Mini Afterburner on my Voron 0.1.

It appears that there are mixed opinions about the Mini Afterburner toolhead in the community. Some users have reported issues or limitations with its performance, while others have had success with it. I thought it would be worthwhile to consider other options like the Mini AfterSherpa that have swapable extruders. At least, I would have a few options to test out.

• [2x] 3010 blower fans*
• [1x] 3007 axial fan*
• [2x] M2.5x8 BHCS/SHCS*
• [3x] M3x35 BHCS/SHCS*
• [2x] M3x5x4 heat inserts

• [1x] LDO 17mm Nema14 Stepper with gear*
• [1x] Bondtech BMG*
• [1x] M3x25 BHCS
• [2x] M3x14 BHCS
• [1x] M3x10 BHCS
• [2x] M3x5x3 heat inserts
• [1x] Short BTFE tube*

* Those can be salvaged from the old Mini Afterburner.

The Mini AfterSherpa is pretty straightforward to assemble. It is working as the Mini Afterburner. I have nothing much to document here. In my case, I’m using a Phaetus Dragonfly Hotend hotend.

TBD

The main objective of this new toolhead was to be able to print TPU. Was it a success? Check this beauty:
