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.

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 materials that have been internally tested; you can access this data by clicking on the material name below.

Printers

As of Jan, 2016, Hyrel Printers are available in two models: Engines and Systems.

Engines and Systems

Engines are open-air models. Detailed information is on the Engines page. Systems are enclosed models. Detailed information is on the Systems page. Both models feature over 200x200x200mm of build volume. Each model can take up to four of our modular heads detailed below. Build plates will get to between 70°C and 85°C, depending on ambient temperature.

Warm Flow

Warm Flow means fluid (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.

Materials, Warm Flow

• Adhesives
• Fimo
• Kato
• Glue
• PCL
• Plasticine
• Resins
• Sculpey
• Wax

Note that some materials (like Fimo, Plasticine and Sculpey) flow more freely when slightly above room temperature, and perhaps too freely at higher temperatures.
