OT: Print your own carbon fiber parts
1 Attachment(s)
Sometimes it can be difficult to find parts that fit folding bikes and mini velos. I've been watching the 3D printing market with great interest but don't think the printed parts would be durable enough for cycling. But this 3D carbon fiber printer might change that:

How are the fiber weaves going to be reproduced?
still a hundred years to go for of the Star Trek replicator to be invented .. |

Q: I usually see composite parts that are made from woven sheets. How do you print with a weave? A: The Mark One™ does not print with a weave, it deposits layers of unidirectional composite in a user-defined orientation that can be specified by layer. In general, unidirectional composites have a higher strength-to-weight ratio in the preferred fiber orientation than composites made with woven fabrics. |

Found this on their FAQ page:

Timeshare buy anyone? :D A good question also would be what's the material/energy cost. |
composite is also catalyzed epoxy a chemical reaction of resin and a catalyst.
