ONYX
Nylon mixed with chopped carbon fiber offers a high-strength thermoplastic
How strong is Onyx Material for 3D Printing?
Onyx has a flexural strength of 81 MPa (11.7 ksi). For more information on Onyx material properties, check out the data sheet.
What is the difference between chopped carbon fiber and continuous carbon fiber?
Chopped carbon fiber is what is mixed into Onyx filament giving it high stiffness and strength. Continuous carbon fiber is a reinforcement fiber that can be printed in long strands, creating composite parts many times stronger and stiffer than Onyx material.

FLEXURAL STIFFNESS (GPa)
HSHT Fiberglass
Delivers the highest impact resistance and heat deflection temperature of Markforged’s continuous fibers
When to print with high strength high temperature (HSHT) fiberglass?
With superior heat resistance and a flexural strength that is second only to carbon fiber, HSHT fiberglass is ideal for applications requiring high heat and impact resistance or high elasticity.
How strong is high strength high temperature fiberglass?
HSHT fiberglass has a flexural strength of 420 MPa (71 ksi) and a tensile strength of 600 MPa (87 ksi). For more information on HSHT fiberglass material properties, check out the data sheet.
IMPACT RESISTANCE (J/m)
Kevlar
Kevlar is a tough, lightweight material, and can bend further than any other fiber, making it ideal for 3D printing.
When to print with Kevlar material?
Kevlar is best utilized in parts that will take a beating. Its low density and high durability make it a great option for applications involving a lot of motion or interfacing with production parts.
What is Kevlar material?
Kevlar is a synthetic fiber developed and produced by DuPont. Know for its light weight and toughness, it is traditionally used in products such as tires, sails, rope, and protective equipment. Kevlar is an excellent material for 3D printing.
FLEXURAL STRENGTH (MPa)
Carbon fiber
Markforged’s stiffest, strongest fiber with the highest strength-to-weight ratio.
What is carbon fiber?
Carbon fiber is a thin filament made up of carbon atoms organized into a crystalline structure. Because of its very high stiffness and strength it is widely used in the aerospace and automotive industries.
How strong is carbon fiber?
Carbon fiber has a flexural strength of 470 MPa (68 ksi) which is 20% higher than the yield strength of 6061 aluminum. Its tensile strength is 700 MPa (102 ksi), more than twice the ultimate tensile strength of aluminum. To learn more about carbon fiber material properties, check out the data sheet.

17-4 PH Stainless Steel
3D print metal more affordably than ever before
Compatible with Metal X
When to print with 17-4 PH Stainless Steel?
17-4 PH Stainless Steel is a hard, stiff, and corrosion resistant stainless steel. It excels in manufacturing environments and as low volume parts.
Working with 17-4 PH Stainless Steel
17-4 PH Stainless steel is best heat treated to maximize strength, hardness, or toughness. H900 condition, heating your part to 900F (482C) for four hours, yields the strongest and hardest possible parts. H1150 condition (1150F instead of 900F) can also be used to maximize toughness at the expense of ultimate tensile strength.

H-13 Tool Steel
Tool steel optimized for high temperature and wear applications
Compatible with Metal X
When to print with H13 Tool Steel?
H13 works excellently in high temperature and can withstand drastic cooling. This, coupled with abrasion resistance and machinability makes it ideal for molds and wear resistant pieces.
Working with H13 Tool Steel
Markforged H13 Tool Steel gets harder, stronger, and tougher when heat treated. We recommend air quenching at 1010C (1850F) and double tempering at 600C (1110F). For improved hardness at the expense of part toughness, you can double temper at a lower temperature (500-550C, 930–1022F).
