Acmer P2 33W vs. Acmer P3 48W
Both lasers compared directly. The better value is marked in green, where this can be said objectively.
The key differences
- The Acmer P2 33W is in a lower price class (€500 to €1,000) than the Acmer P3 48W (€1,000 to €1,500).
- The Acmer P3 48W has the more powerful main source (48 W optical).
- The Acmer P3 48W is rated as laser class 1. According to the manufacturer, the Acmer P2 33W is Class 4, so you need laser safety glasses for the matching wavelength.
- Only the Acmer P3 48W has a built-in camera for positioning.
- According to the manufacturer, the Acmer P3 48W is faster (up to 800 mm/s instead of 500 mm/s). This saves time, especially on large engravings.
