Filament heads are how we print (using FFF or FDM) with filament-based materials which are deposited at over 150°C, depending on the head.
Note that at present, our Filament heads work with 1.75mm filament (actually, 1.6mm to 1.9mm), but not 3mm filament.

The following materials can be printed from Filament heads.
- ABS (Acrylonitrile Butadiene Styrene)
- Flame Retardant ABS

- PETG PolyEthylene Terephthalate Glycol-modified)
- PLA (PolyLactic Acid)
- EcoFlex PLA
- Conductive PLA
- SS PLA (Stainless Steel infused)
- PlastInk_Rubber
- PP (PolyPropylene)
- PVA (PolyVinyl Alcohol)

Filament Heads
Filament-based printing is available through the following heads:
- General Filament Head Videos:
- MK1-250 Extruder for Standard Filament Videos:
- MK2-250 Extruder for Flexible Filament Videos:
- MK1-450 Extruder for High-Temperature Filament Videos:
Please see our Data Sheets as well.
Table of Filament Heads
The following table compares the properties of the various Filament heads, including which heads are recommended for which materials. The MK1 heads drive matieral from one side, with a spring-loaded bearing system to maintain pressure and positioning. The MK2 heads drive the material from both sides, and are designed for more flexible filaments.

Research Papers Citing Hyrel Filament
These are now listed by year here.
Firmware Versions for Filament Heads
Firmware information is listed on our Firmware page.
Settings for Filament Heads
V2: Non-Hydra units shipping through spring 2017 shipped with Repetrel version 2.x.
V3: Hydra units, and other units shipping summer 2017 through summer 2019 shipped with version 3.x, and should consult the version 3.x tables, below. All units should be upgraded to 3.x when it is available. If you run a head with v2 settings on a v3 install, the background will flash red; please make the changes below, from red to blue.
V4: All units shipping as of late summer 2019 are shipping with version 4.x, which has more fields for the heads. Please see below.
| Values for versions 1.x and 2.x will be inicated in RED. |
| Values for version 3.x will be inicated in BLUE. |
| Values for version 4.x will be inicated in GREEN. |
Note that you must flash these settings to the head to make them the new default.
Some settings for the MK-Type heads (like temperature, prime/unprime values) will vary, depending on what material you are printing with. Nozzle diameter should accurately reflect what nozzle you have loaded (0.5mm is default) AND what path width you sliced for (recipe path or extrusion width should be nozzle diameter plus 10%). Having said that, here are our default shipping settings:

Changing Nozzles
How to disassemble the nozzle from the MK1 head:
- Carefully:
- Heat to the printing temperature of the material loaded.
- Move the manual lever to the left, retracting material until it is free of the hobbed shaft, then remove by hand.
- Turn off heat to the head and remove it from the yoke.
- With a 1/4" driver or wrench, remove the nozzle.
- Inspect the nozzle cavity for any stray material; if found, remove with tweezers, solvent, air pressure or other means.
How to reassemble the nozzle on an MK1 head:
- Carefully:
- Ensure your MK1 has no filament loaded.
- With a 1/4" driver or wrench, attach the nozzle.
- Use normal procedure for heating and loading filament.
