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 

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

Proto Pasta has some new filaments with enhanced properties then regular PLA / ABS.

Carbon Fiber Reinforced PLA

Proto-Pasta High Temperature PLA is made from a custom compound consisting of mineral filled impact modified PLA with a nucleating agent to help promote crystallization. Crystallization after printing is what gives this material added heat resistance. To fully realize this advantage, parts must be soaked in hot water or an oven after printing at 60C-80C for 3-5 minutes. This crystallizes the material and makes it much more heat resistant. It does not require a heated bed to print well, but this may help crystallize the material after printing and make oven soaking unnecessary for some parts. High Temperature PLA is a glossy off white, or very light gray. Printed parts look good and have slightly more texture than standard PLA. This material is not translucent like standard PLA.
We have had good results printing at 190C-210C using a .5mm nozzle and direct-drive spring loaded pinch-roll style extrusion head.
Layer adhesion is good and the material has low warpage.

X-winder wraps carbon fiber with epoxy on rotating object. It lowers the price of carbon tubes and elements by up to 80% compared to market prices.

When you look at it from broader perspective it is a from of 3d printer which prints with carbon fiber, it just needs to be upgraded and developed to be able to print non-rotating shapes with full x/y/z movement or at least to reinforce ABS/PLA parts with carbon fiber applied on their surface.

There were similar solutions on the beginning of DIY 3d printing machines development like this 3d printer which printed silicone on rotating tube:

There were successful applications of epoxy surface glued Kevlar and carbon fibers on regular ABS/PLA 3d printed parts which gave them amazing strength:

For next level in carbon printing we need to bring those concepts in a single machine.
Hopefully there will be someone to develop this idea further.
