Bambu Hotend - Bambu Lab H3C
A hardened steel hotend designed specifically for the Bambu Lab H3C printer. Built to handle abrasive materials like carbon fiber, glow-in-the-dark, and metal-filled filaments without losing dimensional accuracy, and engineered for a sub-minute swap so you can mix nozzle sizes and flow rates within a single print.
Available in 0.2 mm, 0.4 mm, 0.6 mm, and 0.8 mm.
Key Features
Built for the filaments that fight back
Carbon fiber, glow-in-the-dark, and metal-fill filaments chew through brass nozzles and take your dimensional accuracy with them. This hotend is hardened steel at HRC 55+, hardened through rather than coated, so the orifice holds its shape print after print.
Quick swap in under a minute
Three screws and the hotend comes off. Three screws and the next one's in. No disassembly, no meaningful downtime — switch to hardened steel for an abrasive job, then switch back when you're done.
Mix sizes and flow rates in one print
The Bambu Lab H3C supports mixing hotends of different sizes — and standard-flow with high-flow — in a single print, so you can balance speed on infill with detail on outer walls.
Nozzle Size Guide
| Nozzle Size | Best For | Common Uses |
|---|---|---|
| 0.2 mm | Small, intricate models where precision matters more than speed | Miniatures, intricate logos, text |
| 0.4 mm | Everyday printing with a balance of speed and quality | Molds, toys, mechanical parts, decorative objects |
| 0.6 mm | Faster prints and high-performance filaments, with some loss of fine detail | Large structural parts, functional household parts, industrial or engineering parts, high-strength models |
| 0.8 mm | Fastest prints and heavy-duty filaments, with reduced fine detail | Large structural parts, functional household parts, industrial or engineering parts, high-strength models |

Notes
- PLA Silk Dual Color is prone to flipping during multi-color printing, which can cause color bleeding — avoid using it for multi-color prints.
- 2.85 mm flexible filaments require the dedicated 2.85 mm hotend and are not supported by these 1.75 mm hotends.
