Industrial laser marking: QR codes, serial numbers and traceability
Why laser marking is useful to identify parts, tools, technical plates and industrial batches with QR codes or variable numbers.
In a workshop, SME or lab, proper part identification prevents costly mistakes. Industrial laser marking engraves references, QR codes, serial numbers and markers directly on compatible supports.
Why mark parts with laser?
- Traceability: link a part to a sheet, batch or version
- Identification: quickly find a tool or component
- Safety: add instructions, assembly direction or warnings
- Professional finish: logo, reference and clean product marking
QR codes and variable numbers
Laser engraving can handle variable marking: each plate or part receives a different number, unique QR code or specific reference. This is useful for inventory, maintenance, prototype batches or quality tracking.
For QR codes, readability depends on contrast, size and support. A test before batch production is recommended.
Common supports
Common supports include anodized aluminum, acrylic, some technical plastics, wood, dedicated marking plates and parts already made by 3D printing or machining.
When to combine with 3D printing or cutting?
A support can be made by 3D printing or laser cutting, then engraved. This creates plates, jigs, enclosures, covers or mounts with integrated identification.

FAQ
Yes up to certain limits. Support, contrast and reader must be tested.
Yes, variable marking suits batches and inventories.
Often yes when the support is compatible and marking must last.
