Agreed, they just keep showing this plastic rectangle, with a flat strip of carbon fiber sandwiched in the middle for reinforcement. Wonderful, but is that the limitations of this machine?

If you look closely at the above image and squint your eyes, I think that's a carbon fiber part it actually printed, that appeared in the video for a split second. It would be great if we could see it close up. It would be even better if they printed a second copy with plastic, and then demonstrated the difference in strength.

Instead, they spent the entire video saying they're going to change the world, and then I guess you're suppose to take their word on it, and just drop $5k on the preorder.
