Print STRONG Parts: The Mark Two 3D Printer

The Mark Two 3D Printer from MarkForged is the world’s only composite 3D printer. Print 3D nylon parts reinforced with carbon fiber, kevlar, or fiberglass right from your desktop.

The Mark Two 3D Printer from MarkForged

Why Composite 3D Printing?

Adding composite materials to 3D printed parts produces functional parts that are stronger than aluminum with no post processing necessary.

You can even embed components in your parts with up to 10 micron accuracy.

Higher strength-to-weight than 6061 Aluminum

The dependability of CNC parts with the flexibility of 3D printing.

Quickly print parts that you used to have to CNC.
You won’t believe how strong and light these parts are!

How it works

The printer actively switches between two nozzles during a print, creating a plastic part reinforced with your choice of materials.

For creating rigid parts that look great.

Onyx combines tough nylon with chopped carbon to create rigid parts that can be used in customer-facing assemblies. Provides extreme dimensional stability and can be combined with additional reinforcements as needed.

  • Heat deflection temperature of 145°C
  • Stunning black matte finish
  • No post-processing necessary

Carbon Fiber

Perfect for applications requiring the greatest possible stiffness and strength.

Prints like plastic, but stiffer than aluminum. This patent pending composite is 20x stiffer than ABS, and is stronger than 6061-T6 aluminum by weight. Carbon Fiber CFF™ is perfect for fixtures, jigs, and parts that need the highest strength-to-weight ratio.MarkForged2

  • Best strength-to-weight
  • Stiffer than 6061 Al
  • Safe, easy, non-toxic
  • Ready to use – no post curing


Ideal for everyday applications where you need strong parts.

Fiberglass filament is the perfect alternative when the strength of a Carbon Fiber Filament is needed, but the stiffness and weight are less critical. This patent pending Fiberglass CFF filament uses the same Continuous Filament Fabrication process for impressive strength, but at a much lower cost. MarkForged3

  • Best strength-to-cost
  • Electrically Insulating
  • Safe, easy, non-toxic
  • Ready to use – no post curing


When you need parts that are durable and resistant to impact.

With higher abrasion and impact resistance Kevlar® filament is perfect for parts that need to be stiff and tough. This patent pending Kevlar® CFF filament uses the same Continuous Filament Fabrication process for impressive strength, but adds some great durability to your parts.MarkForged4

  • Best abrasion resistance
  • Impressive strength
  • Safe, easy, non-toxic
  • Ready to use – no post curing


Fantastically flexible, but tough as nails.

This nylon filament has great fatigue and impact resistance. Nylon is also a great outer protective layer to keep your fixtures and tooling from scratching sensitive parts. It’s also a great choice for tabs, clips, and mechanical fasteners.MarkForged5

  • Tough engineering plastic
  • Low-friction
  • Flexible
  • Non-toxic
  • Inexpensive
