About
- Embed a continuous strand of fiber into plastics
- 2 nozzles - one for plastic and another for fiber?

- If glass fiber is 500ksi - then embedding glass fiber would yield the strength of steel if used at 10% of thickness
How it Works
- Separate fiber and plastic nozzles. Fiber nozzle has cutoff mechanism. https://chatgpt.com/share/6974dd60-eff4-8010-9fe9-14e472e6d6ed
- Do others have plastic-embedded fiber? Would be easier on controls if cutting can happen.
- Lowest brow version would be continuous print without cut or with human assisted cut, and no filament breaks during print.
