Materials

A huge variety of materials can be printed with various extruders on the Hyrel machines.

Can we print your material?

Probably... please tell us:

1. What form it is in at room temperature (powder, granules, filament, gel, etc).
2. Do you need the environment or build surface at a certain temperature?
3. For Filaments:
   1. At what temperature will it be printed?
   2. Is it 1.75mm +/- 0.1mm?
4. For liquids, gels, granules or powders:
   1. At what temperature will it be deposited?
   2. Is it homogeneous or pre-mixed, or do we need to mix it as we dispense?
      1. If mixed as dispensed, at static or dynamic ratios?
   3. How does it harden or cure (by cooling, by heating, with humidity, with UV light (specify wavelength))?
   4. Is it photosensitive? Energetic? Caustic? Any special handling, safety or ventilation requirements?
   5. What viscosity is it during deposition?

Below are the recipes we have so far...

The Importance of Dry Filament

All filaments will benefit somewhat from being kept dry when not in use and/or being pre-heated/dried just prior to use. At Hyrel, we NEVER print PEEK without running it through our preheater/dryer first.

In general, the higher the print temperature (PEEK, PPSU), the more catastrophic moisture in the filament is. And we're talking levels of humidity that standard home devices don't even detect.

Materials Printable on Hyrel Machines

The following is a list of materials with which the Hyrel machines can print; you can sort by any column. Please note that fans should be OFF for the first five layers, then on at the specified speed (see note below).

Note: we've had GREAT SUCCESS and are very impressed with the GeckoTek EZ-Stik build plates, and now recommend them for most thermoplastics (printing at under 350C; they stick TOO well to PEEK and Ultem).

*Note: Hydra printers and newer (2021 BlackJack Edition) 30M and ESR printers can print filaments faster with our HT (High Torque) heads, but your material and geometry will dictate how fast.

• Note: Be sure the fan directs air to the material and not directly at the nozzle.
• Note: In Slic3r, you should slice with a fan value between 0 and 39, which will result in a fan speed between 0 and 99, since we have our fans run between 0 and 100, not between 0 and 255 like other printers. Also note that we leave the fan OFF for the first five layers.

Please note that there is a nice chart on the Simplify3D site that compares materials.
