Deep Engraving Power Analysis: When Watts Matter Most
Deep engraving is where power differences become dramatic. Here’s a real-world test scenario to illustrate:
Test conditions: Engrave a 10-character serial number at 0.3 mm depth on 304 stainless steel
| Power Level | Speed Setting | Passes Required | Total Cycle Time |
|---|---|---|---|
| 20W | 300 mm/s | 6–8 | ~45 seconds |
| 30W | 400 mm/s | 3–4 | ~22 seconds |
| 50W | 600 mm/s | 1–2 | ~10 seconds |
At 1,000 parts per day, that’s the difference between:
- 20W: 12.5 hours of marking time
- 30W: 6.1 hours of marking time
- 50W: 2.8 hours of marking time
For deep engraving at scale, the time savings of higher power compounds rapidly. A 50W laser can literally be the difference between needing one machine or two.
But here’s the flip side: if you’re only deep engraving 50 parts a day, the 20W’s 45-second cycle time is perfectly acceptable. The math only tips toward higher power at volume.
