Mark One website has a following description of their machine:

Brilliant ideas need brilliant materials.
Designed to overcome the strength limitations of other 3D printed materials, the MarkForged Mark One 3D printer is the world’s first 3D printer designed to print composite materials. Now you can print parts, tooling, and fixtures with a higher strength-to-weight ratio than 6061-T6 Aluminum.

Gregory Mark, the President of MarkFoged, also co-owns Aeromation, another carbon high technology company responsible for manufacturing computer controlled race car wings. The wings are typically made out of carbon fiber because of it’s high durability, strength and low weight. They discovered that it is quite a challenging task to manufacture parts out of carbon fiber, because of the time needed and high expense in laying the fiber down piece by piece in the production process. That’s what motivated the development of 3D printer which could simply print the carbon material.

We are waiting for more details and print results!

Mark One is produced by Mark Forged:


Now, after the initial hype, we can say that there are many uncertainties about the technology behind this printer.

  • carbon filament and various carbon fiber technologies have been used in 3d printers before, but as far as I know, no machine has been designed specially for the carbon technology and this would be the first desktop / prosumer printer
  • it is unknown how exactly Mark One prints with carbon fiber: is it a new "special" filament where carbon is mixed in thermoplastics or is it some other technology 
  • carbon fiber (and kevlar) wrapping 3d printed objects to reinforce them was tried before with good results, but it was done by hand: http://diy3dprinting.blogspot.com/2013/06/carbon-and-kevlar-fiber-reinforced-3d.html

Update (18.2.2014.):

here is new, more detailed, video about Mark One:


Screenshot of Mark One webpage showing that the carbon fiber material is 20 times stiffer then ABS and 5 times stronger

Mark One is multimaterial machine that can print objects with two materials with different combinations of core, shell and structural honeycomb 


DIY carbon fiber and fiberglass projects are emerging:
