Architecture
The P2 family is an open-frame diode platform sold in multiple power levels. The current 33W configuration uses the same broad P2 ecosystem, with automatic air assist and optional area extension.
Key specifications
| Laser | 33W diode option |
|---|---|
| Work area | 400 × 400 mm |
| Listed max speed | 500 mm/s |
| Air assist | Automatic 30 L/min |
| Expansion | Optional area extension kit |
| Software | LightBurn / LaserGRBL / ACMER |
What stands out
- 33W diode option
- 400 × 400 mm working area
- Manufacturer-listed 500 mm/s maximum engraving speed
- Automatic 30 L/min air assist system
- Optional area extension kit
- P2 family supports interchangeable 10W/20W/33W modules
- LightBurn, LaserGRBL and ACMER software support
Tradeoffs to understand before buying
- Open-frame architecture
- No built-in Class 1 enclosure in the base platform
- Higher diode wattage does not create fiber-style direct metal capability
- Accessory and enclosure costs should be included in total ownership cost
Who should consider it?
The 33W P2 is primarily a cutting-oriented diode choice. It competes on output power, 400 × 400 mm work area and modularity rather than enclosure or camera-first workflow. Buyers should budget separately for the safety/ventilation setup appropriate to an open-frame machine.
