TL;DR

• Start with the part (size, shape, variability), not wattage.
• Throughput depends on content, setup, and automation - not just laser power.
• Define the mark (contrast, permanence, code size) before choosing hardware.

Once you’ve decided that you want a laser marker instead of another marking process, like dot peen marking or scribe marking, the next decision is: What’s the optimal laser marker for you? This largely depends on three key questions...

1. What is the size and shape of your parts? Are they small and best suited to a desktop laser marker? Are they round or uneven, benefiting from 3D laser marking? Or do you have larger parts or a mix of parts and want a fully portable laser marking unit?
2. The next question is how fast do you need to mark? What’s your marking throughput, and could you benefit from automated laser marking?With industrial laser marking wattage options ranging from 20 watts up to 100 watts and higher, high-speed laser engraving is readily available.
3. The final key question is what material are you laser marking on? Are you laser marking on steel, aluminum, plastic, wood? Do you want to add laser cutting to your laser marking? These questions dictate whether you want to choose a fiber laser marker or a CO2 laser marker. We created the following interactive chart to help you decide:

Common Purchase Mistake: Choosing wattage first. Wattage matters, but the part geometry, fixture approach, and marking requirement usually decide success or failure.

Laser Marker Spec Checklist

- Part material(s) and coatings
- Largest part and smallest marking area
- Required content: text, logo, 2D code, depth requirement
- Target cycle time and daily volume
- Need for portability vs bench station
- Need for 3D marking (uneven or round parts)
- Integration needs: automation, fixtures, extraction, safety

Frequently Asked Questions

1. Do I need a portable laser marker?

If your parts are large, fixed, or spread across a facility, portability can save enormous handling time.

2. What is 3D laser marking?

It is a setup that helps maintain focus across uneven or curved surfaces so marks stay consistent.

3. Is higher wattage always faster?

Not always. Content, setup, and motion strategies matter. Higher wattage helps in many cases, but it is not the only driver.

4. When should I consider automation?

If you mark the same content repeatedly at high volume and need consistent cycle times.
