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.


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.

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.

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 | 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 |

Nothing will impact your 3D printing results like the kind of filament you use. Good filament is highly consistent in diameter, is wound evenly onto the spool with just the right amount of tension, and will not tangle when being unwound. 3D Universe offers a wide range of high-quality filaments to choose from.
