1.2 mm nozzles – maximum throughput for XXL
1.2 mm nozzles are built for extreme volume flows: very wide tracks, very thick layers, and drastically shortened build times. Ideal for trade show objects, negative molds, decorative elements, and very large prototypes.
Strengths of the 1.2 mm nozzle
- Highest material throughput – keep an eye on hotend/heating power
- Solid stable walls, few paths per layer
- Fast production of large-volume projects
Recommended layer heights & usage
- Layer height: approx. 0.60–0.96 mm
- Use: XXL parts, negative molds, trade fair/decor objects
Compatibility & systems
- Volcano (predestined for high feed rates)
- V6/MK8 with suitable, long nozzles
- System nozzles for Revo, Bambu, Creality K-series
Nozzle material choice
- Brass: fast heating, homogeneous melt pattern
- Hardened steel: mandatory for CF/glass/particle fillers
- Coated high-flow nozzles: for maximum stability at high flow rates
FAQ on 1.2 mm nozzles
Do I absolutely need a high-flow hotend?
For the best possible speeds, yes. Standard hotends tend to reach limits at 1.2 mm.
How do I choose the layer height?
0.60–0.96 mm are practical. Surface becomes rougher, stability increases.
Which materials work well?
PLA/PETG/ASA run stably; for abrasive filaments, use hardened or coated nozzles.
What to consider in the design?
Large radii, fewer delicate details, design wall and infill strategy for wide paths.
