Frequently Asked Questions

Answers to the most common questions about laser marking, UDI marking, black marking, and our process.

What is the difference between laser marking and laser engraving?

Laser marking modifies the surface of a material without significant material removal — for example through oxidation (black marking) or colour changes. Laser engraving removes material, creating a measurable depth. Both methods are permanent; the choice depends on the material, application, and quality requirements.

What materials can you mark?

We mark virtually all common materials: titanium (Ti6Al4V-ELI, Grade 4), stainless steel (all grades), chrome-cobalt alloys, aluminium, powder-coated metals, PEEK, ceramics (zirconia, Al₂O₃), glass, and piezoceramics.

What is black marking and why is it important for medical devices?

Black marking is a process where UKP lasers create a deep black, corrosion-free surface on metals — through nano-structuring, not through colour or coating. The marking is autoclavable (up to 134 °C, Class B), chemical-resistant, and permanently readable under sterilisation conditions.

What is UDI marking and are you certified for it?

UDI (Unique Device Identification) is required by MDR 2017/745 for Class I to Class III medical devices. We are certified to ISO 13485:2021 and mark MDR-compliant DataMatrix codes. All batches are fully documented and archived for 15 years.

What advantage do UKP lasers have over standard fibre lasers?

UKP lasers operate with extremely short pulse durations so no thermal energy enters the material (cold ablation). Result: deep-black, corrosion-free markings without heat-affected zones, burrs, or distortion. Standard fibre lasers produce grey-brown, corrosion-susceptible markings — not suitable for medical technology.

What batch sizes are possible?

From 1 to 100,000+ parts. Average order size: 3,000 to 5,000 parts. Capacity: 50,000+ parts per week. No minimum order quantity.

How long are quality documents archived?

All production and quality data are archived for 15 years — in compliance with EU MDR requirements for the service life of implants and medical devices.

How does an enquiry work?

Send us your component drawing or sample parts. We assess markability, clarify technical details, and provide a non-binding quote. After order confirmation, you receive a first-piece report for approval before series production.

What are your lead times?

Standard lead time: 10 working days. For batches under 1,000 pieces, shorter lead times are often achievable.

Still have a question?

We respond personally within one business day — not automated.
