Welcome to Hyrel!
With literally thousands of materials to print on the Hyrel Printer, we have broken down the list of materials into logical groups based on their printing temperature and type of head used to print them.
A quick intro to many of the functions of a Hyrel printer can be found here.
If you are planning on using the heads which photoinitiate crosslinking, make sure you specify the correct wavelength of LED for your material.
A standard material printing data sheet has been created for many of the materials that have been internally tested; you can access this data by clicking here.
Always be sure of what material you are using, and what will be off-gassed.
Our current price list can be found here.

Software and Firmware
Our equipment runs our proprietary Repetrel software and firmware. This was not done to be difficult, but because we didn't want to be restricted by the limitations of other printers. This is how we have the ability to adjust things like the Z position and material flow rate during a print. For a more in-depth look, please see the Repetrel page. To download and install, please see the Software page.
Hardware
There are two categories: Printers and Heads (or Accessories).
Printers
As of May, 2017, Hyrel Printers are available in the following models: Hydras are our larger, gantry models; Systems are our tabletop, enclosed models; and Engines are the smaller, unenclosed models - available in High Resolution (HR) and Standard Resolution (SR) versions.
All models use our Repetrel software and any slicer (Slic3r support provided). Each model comes with a Windows PC, either tablet or full desktop style. We operate our print heads via CANbus.

The Hydra Series
The Hydra series formerly the Model 16A and 17A has hard resolution (with encoder feedback) of 20 microns in the X and Y, and 0.8 microns in the Z in standard mode. In microstepping mode, we can achieve soft resolution of 4 microns in the X and Y. It comes standard with two tool positions, but can take additional yokes to handle more.
There are four models, as detailed above. The differences are:
- The Hydra 340 sits on a countertop, has a 300x400x250mm build volume, and has no CO2 laser option.
- The Hydra 430 stands on the floor, has a 400x300x250mm build volume, and has 40w and 80w CO2 laser options.
- The Hydra 640 stands on the floor, has a 600x400x250mm build volume, and has 40w and 80w CO2 laser options.
- The Hydra 645 stands on the floor, has a 400x400x500mm build volume, and has 40w and 80w CO2 laser options.
Overview of the Hydra line
The System 30M, 30, and 23
Systems are enclosed Detailed information is on the Systems page. The System 30M replaced the System 30, which replaced the System 23. For you history buffs and Kickstarters.
The Engines
Engines are open-air models. Engines can take up to four heads at once, either working cooperatively on a one print, or making duplicate copies of a small print at the same time. Build volume is 200mm x 200mm x 200mm (X/Y/Z). Detailed information is on the Engines page.

The Warm Flow Process
Warm Flow is our term for fluid or emulsified (non-filament-based) materials which are deposited at up to 150°C, with or without UV Crosslinking, depending on the head.
PCL and other medium temperature material can be printed directly from Pellets the size of small peas. If you pulverize or powder your polymer, it is possible to pre-mix the material dry and test different alloys of plastics.
For more details, see the Cold and Warm Flow page.

Tool Position Accessories
Lasers
Hot-swappable Lasers are available in the following configurations:
- The LA5-808 is a diode laser, 5W at 808nm, and due to its wavelength, it is best suited for darker material.
- The LA6-450 is a diode laser 6W at 450nm, and performs well on opaque material of any color.
- The LI40 is an integrated 40w CO2 laser, and performs well on translucent as well as opaque material; available on our Hydra models only.
- The LI80 is an integrated 80w CO2 laser, and performs well on translucent as well as opaque material; available on our Hydra models only.
The Reflectivity and Transparency or Translucency of your material will have a great impact on the effectiveness of the laser. Safety glasses are included with each laser.
Spindle Tools
ST1
The ST1 is intended for light drilling and routing operations (especially circuit board work), and provides between 500 and 5000 RMP (depending on load) to a 1/8" chuck. Our Repetrel software can process Gerber and DRL files for the Spindle Tool and/or the Lasers.
The ST3 is presently in testing, but provides more power; available on our Hydra models only.
Other Tool Position Accessories
The following accessories each take up a tool position while performing more passive functions:
- The Inspector microscope provides magnification.
- The Quiet Storm fan provides additional cooling.
- The Tramming Tool, provided with every printer, is used to level the build surface.
Non-Tool Position Accessories
The following non-head accessories are also available:
- The Feed Chamber Cooling Fan mounts on Hot Flow heads to provide additional cooling to the feed chamber. This is desirable with low temperature filaments like PLA.
- The Printer Support Kit is included with every printer, and includes a build plate, blue tape, and a variety of handy tools like tweezers, razors, and a spatula.
- The SDK | Software Developer's Kit provides hardware, software, and the source code for developing your own firmware for your own compatible heads.
- The LTK | Luer Tip Kit provides an EMO to Luer adapter and a variety of luer lock needles.
- The Syringe Kit provides syringes in quantity.
- The Drill Bit Kit provides an assortment of drilling bits and end mills for the Spindle Tool.
- The Filament Kit provides a variety of filaments to get you started with your printer.
