While I agree a part will be stronger when sandwich between continuous fiber layers, your analogy with LEGOs is flawed because there considerable random overlap among chopped fibers. You are using a regular pattern of a 2x2x4 LEGO blocks in which you an alternating blocks only in the Z-direction. At the least, That would need also replicate that pattern in both the X and Y -directions by using, e.g. 1x1x4 1x1x6 LEGO blocks. Better would be to use a random pattern. Both of which would be considerably stronger than you are suggesting.
This is the best and most succinct video on this topic yet! Very well done. Thank you for making this as it is contributing to one of my college classes.
The MKII, X7, FX10, and FX20 are capable of print CFR. The Onyx One and Onyx Pro are not capable of printing CFR. I think that depends entirely on your use case for the machine. If you'd like, I can have someone reach out that can recommend a solution based on your needs.
Great examples! Do you think that it is a feasible ideea to 3d print carbon fiber threaded rod (M6 size) for a linear motion mechanism (to lift 2 kg for 1 time per day)? I need to avoid metal in my environment. What printer should I looking for continuous carbon fiber?
Did you find anything in the meantime? My guess is there are patents covering this methodology that prevents anyone building extruders that you can just buy.

We are so glad to hear that this video was useful for you and for your college class.
Brilliant explanation! Compliments for the extremely clear and interesting ways you explain the topic.
Thank you, happy you enjoyed!
Vey informative. Good use of analogies. Thanks for posting!
That spaghetti move for shear, compression, etc. is really good.
just go to 1:43 for the punchline - and thank you for posting this
Glad you enjoyed!
Kind of implies that stranded plus chopped is stronger than stranded alone - probably not. Right?
Could you 3d print bike frames and parts with your Markforged printers? The desktop versions?
hes deffo reading off a slide lool
it would be great if you could sell just the extruder as a standalone tool
Can markforged show a sample on how you make flexures with the X7 using Nylon?
Hi thanks for share ¿Are all printer capable to print continous carbon fiber? ¿which printer do you recommend?

Any evidence of thermoplastic with chopped fibre being weaker than pure thermoplastic due to the inclusions and the fracture lines they create?
Great examples!

You can't resume that the continuous fiber is the best, it is depends on applications and the forces that you have in a case concrete
Thank you
Excellent!
Thanks..that clear some things up. Is it safe working with the chopped cf parts? I heared they can be airborne and breathed which is not healthy
were can I buy the extruder and software

2:50 its funny moment . but video was good :)
Which is the software used for fiber alignment
We have our own slicing software called Eiger. You can learn more about our software on our website: markforged.com/eiger/
wish you actually compared a real part instead of legos tho!
2:59 hahahhaa what was that? you dont trust in that example ?
Could you break a 3D printed fart. It sounds like that in your commercial :-) hehe
Great video... But the safety glasses... They're Legos
If anything he should be wearing safety boots
This is common sense.
I tried it with my own hair and salt *joke*
