Dual Extrusion PLA Filaments
This PLA changes from Green to Pink depending on the angle you view it from!
This PLA changes from Gold to Pink depending on the angle you view it from!
Nylon Filaments
This is the strongest, most clean printing Generic PA6-CF
A tough blend of Nylon from a reliable company.
The best Nylon that’s not mixed with Carbon fiber. This unique mix is both strong and flexible. A great overall Nylon!
910 Nylon is one of the most widely used Nylons in Robot combat, as it’s very strong.
One note: 910 Nylon is highly prone to warping and shrinkage. It’s very important to scale up the file sizing to 101% to account for the shrinkage.
We will do our best to reduce warping, but can’t guarantee a warp free print in this material.
Onyx Filament
This is the strongest, and cleanest printing Nylon. There is no better overall filament for strength.
This is the most recommended by Malice!
PEBA-S Filament
PEBA-S is a great flexible, but strong material. Like TPU, but a bit stronger for the weight.
Nylon is 1.10g/cm3
Peba is 1.01g/cm3

Generic blue tpu
Overture White TPU 
Overture Red TPU
Temperature sensitive filaments will go from one color to another when they get warm!
Temperature Changing PLA Filments
An amazing filament that starts as Gray, but changes to Orange, and then yellow as you increase the temperature!
A beautiful purple, to a vivid pink!
An adorable blue to pink color changing PLA.
Temperature Changing TPU Filament
A wonderful tpu. Great quality and fun colors!
Continuous Fiber Reinforcement Types
Fiberglass is Markforged’s entry-level Continuous Fiber —a material capable of yielding parts 10x stronger than ABS when laid into a Composite Base material like Onyx. Fiberglass is the flagship material of the Onyx Pro and X5. It is printable on the Mark Two and X7, providing a more affordable alternative to Carbon Fiber.
What is fiberglass?
Extremely thin strands of glass bundled together into a fiber. Fiberglass is traditionally used in composites for boat, automobile, and aircraft manufacture.

Kevlar® CFF™ (Continuous Filament Fabrication) Spools. Kevlar has the best abrasion resistance and is our most flexible fiber material. For when you need parts that are durable and resistant to impact, Kevlar will take the blow. What is Kevlar? Kevlar is a synthetic fiber developed and produced by DuPont. Known for its light weight and toughness, it is traditionally used in products such as tires, sails, rope, and protective equipment.
Carbon Fiber CFF™ (Continuous Filament Fabrication) Spools. Carbon fiber is high performance, superior and lightweight. It has the highest strength to weight ratio for 10 times the strength of Onyx. Carbon fiber reinforcement is perfect for applications requiring the greatest possible stiffness and strength but as light a feather. We also recommend you purchase an additional Nylon spool for every CFF spool. 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 540 MPa (78.3 ksi) which is 20% higher than the yield strength of 6061 aluminum. Its tensile strength is 800 MPa (116 ksi), more than twice the ultimate tensile strength of aluminum.
