These are two different nozzle ecosystems. A Revo nozzle is not a FlowTech replacement. Identify the installed hotend before buying, then check the exact filament’s minimum nozzle requirement.
Use this compatibility-first shortlist
| Installed system | Candidate | Why to consider it |
|---|---|---|
| Revo | Standard ObXidian 0.4 mm | Standard abrasive-capable route when that orifice is permitted |
| Revo | High Flow ObXidian 0.4 mm | Investigate only when extrusion flow limits the job |
| FlowTech | CM2 hardened-tip 0.6 mm | Wider-orifice route when appropriate for the filament |
| FlowTech | CHT CM2 hardened-tip 0.4 mm | Higher-flow candidate with filled-material clogging tradeoffs |
Flow and clog clearance are different questions
A high-flow design may be useful for a genuinely flow-limited part. It does not make a too-small opening suitable for every filled filament. The matched feedback includes successful abrasive printing and difficult clogs, so choose the minimum permitted orifice before chasing throughput.
- Verify nozzle/hotend interface and installation procedure.
- Confirm the exact material permits the selected opening.
- Keep the printer’s temperature limits separate from the nozzle component’s rating.
- Requalify the slicing profile when changing nozzle size or flow design.
The carbon-fiber nozzle guide explains the selection sequence. For PA composites, use it with the nylon shortlist and the material’s drying instructions.
