3D Laser Marking: Case Study

When an Italian boutique wheel maker needed to etch serial numbers around the curved spokes of forged-magnesium rims, ink pads smeared and dot-peen needles cracked the thin wall. They installed a 3D galvo fiber marker with 200 mm Z-axis travel and 3D field lens. Now a single 30 s pass marks the hub, spoke bed and rim flange without refixturing, eliminating 5 minutes of handling and 0.7 % scrap caused by mechanical contact.

The same 50 W MOPA source that produces jet-black datamatrix on anodised surfaces also frosts a high-contrast logo into powder-coated valleys 8 mm deep. Pulse width is stretched to 200 ns so the coating sublimates instead of burning, keeping the polymer substrate below 80 °C. Line-cycle time dropped from 45 s to 9 s per housing, letting the line hit 400 parts/h in a footprint that used to hold two masking stations and a chemical etch booth.

A German medical implant supplier switched from CO₂ mask marking to 3D fiber last year. Their Ti-6Al-4V tibial plates have curved ridges only 0.4 mm thick; laser focus follows the contour within 30 µm, producing a uniform 5 µm black oxide trace that survives passivation baths. Lot size dropped from 500 to 1 because each plate carries a unique traceable code, cutting finished-goods inventory by €180 k while raising overall equipment effectiveness from 68 % to 92 %.

Principales caractéristiques et avantages

Klear Laser integrates advanced 3D dynamic focusing technology to surpass the limitations of traditional flat-field marking. Our systems automatically adjust the focal length during the marking process to accommodate complex surface geometries. This capability allows for precise marking on curved, stepped, cylinder, or irregular substrates without requiring mechanical movement of the workpiece or the laser head.

We utilize premium fiber laser sources from industry leaders like JPT and Raycus to ensure beam stability and operational longevity. The integration of JPT MOPA (Master Oscillator Power Amplifier) technology is particularly advantageous for 3D applications because it offers adjustable pulse widths. This flexibility allows operators to fine-tune energy input for specific materials, resulting in high-contrast marks and controlled heat zones even on sensitive components.

The core of our superior performance lies in the specialized 3D dynamic scanning head. Unlike standard 2D galvo heads that operate on a fixed X-Y plane, our optical systems incorporate a movable Z-axis lens that shifts in real-time. This optical design maintains a consistent spot size and high energy density throughout the entire marking field, even on surfaces with significant height variations or deep cavities.

Industrial manufacturers rely on this technology for deep relief engraving and precision mold texturing. The control software works in tandem with the hardware to slice 3D models into layers for precise, iterative material removal. This results in intricate textures and consistent depth that standard laser markers simply cannot achieve efficiently.

Applications industrielles

3D laser marking creates permanent identifiers on complex curved surfaces common in transportation manufacturing. Automotive plants use it for VINs on chassis components and traceability codes on transmission housings. These marks withstand extreme heat, oil exposure, and mechanical wear throughout the vehicle lifecycle. Precision depth control ensures readability for automated inspection systems.

Aerospace manufacturers rely on 3D laser marking for critical part serialization on turbine blades and structural fittings. Marks comply with MIL-STD-130 for UID compliance, surviving high-temperature operations and rigorous maintenance. The non-contact process avoids micro-cracking in sensitive nickel alloys and composites essential for flight safety.

Marine engineering applies 3D laser marking to propeller hubs, valve bodies, and pump casings exposed to saltwater corrosion. Permanent markings endure harsh offshore environments and frequent cathodic protection systems. This traceability meets stringent SOLAS and IMO regulatory requirements for vessel component tracking.
