The HSD-10 is a special heated extruder with a polyamide reservoir for emulsions which print at temperatures up to 100°C.

This includes the following materials:

</div>

== Description ==

The HSD-10 heads accept our specially modified Ardes 10cc syringes. Industry standard luer tips or needles are available from a variety of sources.

== UV Crosslinking ==

All of our reservoir-based heads can take a [[UV_Array|UV Array]], mounted around the nozzle, or a [[UVP|UV Pen]], mounted in another tool position.

The [[UV_Array|UV Arrays]] are lower power, and available in 280, 310, 365, 405, or 450 nm.

The [[UVP|UV Pens]] are higher power, and available in 365, 405, or 450nm.

== Syringes ==

The HSD-10 heads accept our specially modified Ardes 10cc syringes. The same syringe purchased from other suppliers WILL NOT FIT in our HSD-10 without our extensive modifications. See these videos for examples of how we modify the [[https://www.youtube.com/watch?v=B0lvN-aPYHI syringe cap]] to work with our equipment.

== Loading the Head onto the Printer ==

As with all Hyrel heads, the following process should be followed:

# Start with a level bed and Repetrel running and connected to the printer.
# Load the gibs on the Head into the gib slots on the Yoke from above and slide the head down into place; the last mm of travel should be done gently, ensuring that the electrical connector seats properly (firmly and completely) into the receiving connector.
# Ensure the LEDs on the print head are flashing - this means the Head is communicating with the Motion Controller.
# Tighten the thumbscrew in the rear, to prevent the head from moving relative to the Yoke.
# If the Head doesn't show up in Repetrel, press and release the RESET button on the front of the printer.
# Once the Head is shown in repetrel, proceed to setting your Z-Zero position.

== Loading material into the Head ==

Loading:

* Care should be taken to avoid air pockets, as this will introduce delay when starting and stopping material flow.
* The plunger adapter will need to be adjusted up or down to match the position of the plunger for the amount of material you have loaded; do this with the manual feed lever at the top left of the 103 hothead controller board. See videos, above.

Unloading:

* Unloading is the same process as loading, only in reverse. Tubes and nozzles should be cleaned thoroughly after use.

== Default Parameters ==

Default settings for all HSD heads are shown on the [[Cold_and_Warm_Flow]] page.

== Adjustments ==

The only adjustments needed should be changes to the PRIME and UNPRIME settings, and will have to be dialed in based on how viscous and compressible your material is, and how narrow a nozzle or luer tip you are using.. In dialing in new settings, I usually double or half the settings for both STEPS and TIME, then make another print and reassess.

== Firmware ==

Please see the [[Downloads]] page for the current firmware for your heads and your version of Repetrel.

Note that the default for version 3 is _TUBES_35K.hex for standard use, or _TUBES_49V.hex with the Clench Valve. On version 4 and later, ALL heads take the same firmware.

== Maintenance ==

These syringes are expensive, and we recommend fully disassembling and cleaning (or sterilizing) them between uses, based on your materials and your needs. Ensure that your temperature control reservoir and supply are kept clean.
