How it Works
Chat - [1]
- Separate fiber and plastic nozzles. Fiber nozzle has cutoff mechanism. https://chatgpt.com/share/6974dd60-eff4-8010-9fe9-14e472e6d6ed. This one uses carbon fiber or glass fiber.
- 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.
- Tensile stronger than mild steel.
- 30% fiber in continuous fiber prints - [2]
- Nylon is best plastic, as it's polar like glass
- Steel isn't great - doesn't bond well to plastic like fiberglass.
- Spring steel - 0.4 mm at $40/lb at McMaster [3]. Or 0.5 mm at $20/lb.
- Stranded stainless - $10/lb from china - [4]
