Precision marking in the medical industry: The role of TRUMPF TruMark Lasers

In the highly regulated medical industry, ensuring process reliability and traceability is paramount. The ability to precisely inscribe medical devices, instruments, and implants is not only a regulatory requirement but also a critical aspect of patient safety and product performance. TRUMPF, a leader in laser technology, provides an exceptional solution with its TruMark and TruMicro Mark laser systems, designed to meet the stringent demands of medical engineering. 

Challenge: Meeting rigorous standards and ensuring traceability 

Medical devices must adhere to stringent regulations to guarantee safety and efficacy. The Unique Device Identification (UDI) system requires each medical device to be marked with a unique identifier. This marking must be durable, corrosion-resistant, and easily traceable throughout the product’s lifecycle. Traditional marking methods often fall short in meeting these requirements, especially when it comes to marking sensitive surfaces without causing damage or leaving residues. 

Solution:  TRUMPF TruMark and TruMicro Mark lasers 

TRUMPF’s TruMark lasers are engineered to address these challenges with unmatched precision and reliability. Whether working in simple 2D, or complex 3D free-form geometries, the highest standards can be achieved when marking the most delicate surfaces. The TruMark series, particularly the TruMicro Mark, offers several advantages: 

• Precision and versatility: The TruMark lasers can mark a wide variety of materials with the appropriate power control and pulse energy for each one. This versatility is crucial for the medical industry where a variety of materials are used for different devices and instruments. 
• High contrast: The TruMicro Mark generates deep black UDI codes with extreme pulse peak power, ensuring high contrast and enhanced corrosion resistance. This is essential for traceability and compliance with regulatory standards. 
• Minimal heat penetration: With short pulse durations in the range of picoseconds or femtoseconds, TruMark lasers ensure minimal heat penetration. This feature prevents damage to sensitive surfaces and eliminates residues, maintaining the integrity and functionality of medical devices. 
• Corrosion resistance: The use of ultrashort pulsed lasers in black marking creates micrometre structures on the surface. These micro-structured surfaces reduce directed light reflection, producing a deep blackening effect that is visible from any angle. This process also maintains corrosion resistance by keeping the heat-affected zone extremely small, allowing sufficient free chromium to promote self-healing of the passive layer.  
• Complete turnkey solutions: TruMark and TruMicro Mark are available as a complete system within a TruMark Station or as equipment for integration into existing production lines. This flexibility makes it suitable for various applications, from deep black marking to high-quality engraving to annealing. 

Integrating TruMark laser systems 

Integrating TRUMPF’s TruMark laser systems in medical device manufacturing involves several key steps to ensure seamless integration and optimal performance: 

• Assessment and customisation: The process begins with an assessment of the specific marking requirements for the medical devices in question. TRUMPF’s experts work closely with manufacturers to determine the best laser system configuration, including the appropriate wavelength and pulse duration. 
• Installation and training: Once the system is specified, it is installed either as part of a TruMark Station or integrated into existing production equipment. TRUMPF provides comprehensive training for operators to ensure they are proficient in using the system and understanding its capabilities. 
• Quality control and validation: After installation, rigorous quality control measures are implemented to validate the marking process. This includes verifying the durability, contrast, and corrosion resistance of the markings to ensure they meet regulatory standards. 
• Ongoing support and maintenance: Headland offers ongoing support and maintenance services to ensure the laser systems continue to operate at peak performance. This includes regular updates and troubleshooting assistance, helping manufacturers maintain high levels of process reliability. 

Conclusion 

In the medical industry, where precision, reliability, and traceability are non-negotiable, TRUMPF’s TruMark and TruMicro Mark laser systems provide an ideal solution for marking medical devices and instruments. With their ability to create high-contrast, corrosion-resistant markings on a variety of materials, these lasers ensure compliance with UDI regulations and enhance product safety. The TruMicro Mark stands out as an optimal solution for manufacturers seeking to achieve the highest standards of quality and reliability in their marking processes.
