MarkForged's Onyx is a material that is ideal for customer-facing parts that need to look good while standing up to industrial requirements.
Onyx is based on a remarkably tough nylon, but also provides parts with stiffness equal to or greater than any pure thermoplastic material available for professional 3D printers. It’s easy to print and far more rigid in assemblies.
Onyx can be used alone, or further reinforced with embedded continuous carbon fiber, Kevlar, or fiberglass layers - parts truly transcending the limits of conventional 3D printed plastic.
The following is useful information regarding printing with Onyx:
- Like all MarkForged materials, parts printed using Onyx are ready for use right off the print bed.
- Onyx has a heat deflection rating of 145°C
- Parts printed in Onyx warp far less than parts printed in Nylon
Printing significant amounts of Onyx conditions the print head in a way that tailors it toward printing Onyx. Customers are free to begin printing Onyx at any point after printing Nylon. However, once you start printing Onyx, your printer will be conditioned for Onyx and you will not be able to switch back to Nylon. Customers interested in continuing to use both materials are encouraged to purchase a second print head or printer.
The following chart outlines the product specifications for Onyx as well as for Nylon.
|Tensile Strength (MPa)||ASTM D638||36||54|
|Tensile Modulus (GPa)||ASTM D638||1.4||0.94|
|Tensile Strain at Break (%)||ASTM D638||58||260|
|Flexural Strength (MPa)||ASTM D790*||81||32|
|Flexural Modulus (GPa)||ASTM D790*||2.9||0.84|
|Flexural Strain at Break (%)||ASTM D790*||N/A**||N/A**|
|Heat Deflection Temperature (°Celcius)||ASTM D648
*Measured by a method similar to ASTM D790
**Flexural Strain at Break is not available because neither material breaks before the test ends.
