Match wavelength and configuration to your required marking result
Choose the closest answers for your most demanding regular job. The recommendation narrows the machine range; a sample test confirms the final process.
Why material comes before laser wattage
A reliable selection starts with wavelength compatibility, then adds the required mark, cycle time, field size and production controls.
Match the wavelength
Fiber, MOPA, UV and CO₂ interact differently with metals, plastics, glass and organic materials.
Define the accepted mark
Contrast, color, depth, edge quality, code grade and heat effect determine the useful process window.
Build the production system
Fixtures, rotary axes, vision, variable data and line controls convert a laser source into a repeatable process.
Compare the four main laser marking technologies
Use these as starting directions, then confirm the exact result on the real material and surface finish.
Fiber Laser Marker
Fast, permanent marking and engraving on metals and selected engineered plastics.
- Logos, serial numbers, QR codes and barcodes
- Steel, stainless, aluminum, brass and copper
- 20W to 100W common power choices
MOPA Laser Marker
Adjustable pulse width for black marks, selected colors and controlled surface effects.
- Black marking on anodized aluminum and stainless
- Selected stainless color effects
- More flexibility for sensitive plastic marking
UV Laser Marker
Fine, low-heat marking for sensitive materials, compact codes and clean edges.
- Plastics, glass, ceramics and electronics
- Micro text, QR codes and medical components
- 3W to 15W common power choices
CO₂ Laser Marker
A strong fit for organic materials, packaging and many non-metal surfaces.
- Wood, leather, paper, rubber and acrylic
- Date codes and batch codes on packaging
- 30W to 100W common power choices
Choose the likely machine by material and target effect
This matrix helps buyers compare the first machine direction without treating every material of the same name as identical.
| Material / Result | Best Starting Technology | Typical Power Direction | What To Validate |
|---|---|---|---|
| Steel and stainless codes | Fiber laser | 20W-50W | Contrast, depth, cycle time and corrosion requirement |
| Black stainless or anodized aluminum | MOPA laser | 30W-60W | Surface finish, pulse settings and mark durability |
| Color effect on stainless | MOPA laser | 30W-60W | Alloy, viewing angle, color tolerance and consistency |
| Heat-sensitive plastic | UV or MOPA | 3W-15W UV or tested MOPA range | Resin, pigment, additives, edge quality and contrast |
| Glass and ceramics | UV laser; selected CO₂ uses | 3W-15W UV | Microcracking, stress, opacity and focus depth |
| Wood, leather, paper and rubber | CO₂ laser | 30W-100W | Charring, smoke extraction, edge color and speed |
| Deep metal engraving | Higher-power fiber laser | 30W-100W | Depth per pass, debris, edge quality and total cycle time |
Specify the hardware around the laser source
Part presentation and data control often decide whether a marking project is easy to operate or difficult to repeat.
Lens and working area
Smaller fields generally support finer detail and higher energy density; larger fields need careful focus and cycle-time review.
Rotary axis and fixture
Hold tubes, rings, tools, fittings or cups concentric and maintain correct focus around the circumference.
Motorized Z or 3D focus
Compensate for height variation, curved surfaces and product families with different working distances.
Serial, QR and database link
Connect production data while controlling duplicate codes, operator permissions and marking records.
Positioning and verification
Locate variable part positions, confirm orientation and check code readability before release.
Enclosure and extraction
Control laser access, smoke, particles and odors according to material and site safety requirements.
Plan more than a visually clear QR code or serial number
Production traceability also depends on data integrity, code grading, fixture repeatability and records that remain linked to the correct part.
Control the source data
Define where serial numbers, batches and product IDs originate and how duplicates are prevented.
Protect code quality
Set minimum cell size, contrast, quiet zone and acceptance grade for the final reader or verifier.
Record the result
Store marking status, recipe, time, operator and verification result when the production process requires it.
Approve the mark on your actual material.
The selector narrows the technology and configuration. A sample test confirms contrast, depth, heat effect, readability and realistic cycle time before purchase.
Send the Part
Share material, surface finish, artwork, code size and target result.
Compare Marks
Test suitable wavelength, power, lens, speed and process settings.
Approve the Setup
Review photos, video, mark quality and recommended configuration.
Compare marking technologies and production systems
Use the recommended machine page to review applications, then confirm the final choice with a sample mark.
