Man, that is quite the hype video.
It doesn't look like it actually can print free standing carbon fiber parts though, just reinforce existing PLA printed parts, which seems like a bit of a nightmare from an alignment point of view.
Seems like that is a limitation of using carbon 'thread' as opposed to carbon sheets. Aren't most carbon fiber objects made from sheets that are shaped, baked and bound together? That doesn't seem like it would convert to fiber very well.
In short, it seems like a neat way to reinforce printed parts, but in no way does this seem to be the 'print carbon fiber' like they are selling it. You can't just plug in a model for a 3D printed piece and get out a gorgeous cabin piece.
As an additional aside, isn't there still a step of baking required? They didn't talk about that, is it a different process? (perhaps the thread is heated ahead of time?)
- alirazaq 13y agoAs far as I know, the only "printer" that can produce carbon fiber parts in three-dimensions is the circular loom Toyota developed for the Lexus LFA. http://www.youtube.com/watch?v=AScfESzQzIQ http://www.youtube.com/watch?v=AScfESzQzIQ

- lotsofmangos 13y agoAren't most carbon fiber objects made from sheets that are shaped, baked and bound together? Some of the strongest ones are made from laid unidirectional thread done in the directions you want to have the least stretch, the woven stuff is put on top to give it the look. Also, all carbon fiber parts are FRP, this is just using a different P. It will be weaker than a baked part, but it clearly has potential as it needs no tooling.
