Black Laser Marking | Ideal for Medical Products<\/h1>\n\n\n\n

<\/p>\n\n\n\n

Permanent, Corrosion-Resistant Black Laser Marking Ideal for Medical Technology<\/strong><\/h2>\n\n\n\n

<\/p>\n\n\n\n

Achieve high-contrast, FDA-compliant UDI codes<\/strong> on medical devices and other components using ultrashort pulse lasers \u2013 without compromising material integrity or using harsh chemicals.<\/strong><\/p>\n\n\n\n

\n\n
\n\n \n \ud83d\udca1\n <\/span>\n\n
\n\n Key takeaway:<\/strong> Ultrashort pulse lasers restructure a surface instead of burning it. The result is a deep, matte black mark<\/strong> that survives autoclaving and passivation.\n\n <\/div>\n\n <\/div>\n\n<\/div>\n\n\n\n


Meet the Requirements of the Medical Field<\/h2>\n\n\n\n

Many industries need reliable and efficient processes that deliver high-quality results, but perhaps none more so than the medical equipment field<\/strong>. Between handling compliance needs, maintaining patient safety, and avoiding faulty parts and marks, medical device production facilities have a lot to juggle, and black laser marking is the ideal solution<\/a> for these concerns.<\/p>\n\n\n\n

The Challenges of Sterilization and UDI Compliance
<\/h3>\n\n\n\n

Because of their use in patient care, medical devices need to undergo aggressive cleaning cycles<\/strong> to ensure sterilization. These cleaning cycles often feature high temperatures, harsh chemicals, and ultrasonic baths which, over time, can significantly wear down inkjet markings and traditional thermal laser markings created via annealing. This is because oxides are created that can eventually fade during repeated autoclaving and passivation.<\/p>\n\n\n\n

\n\n\n\n\n\n\n\n\n\n\n\n
\nMarking Method\n<\/th>\n\n\nHow It Holds Up to Sterilization\n<\/th>\n\n<\/tr>\n<\/thead>\n\n
\nInkjet marking\n<\/td>\n\n\nWorn down over time by high temperatures, harsh chemicals, and ultrasonic baths.\n<\/td>\n<\/tr>\n\n
\nThermal laser marking (annealing)\n<\/td>\n\n\nCreates oxides that can fade during repeated autoclaving and passivation.\n<\/td>\n<\/tr>\n\n
\nBlack laser marking (USPL)\n<\/td>\n\n\nIntrinsically corrosion-resistant surface structure that remains legible after numerous cleaning and passivation cycles.\n<\/td>\n<\/tr>\n\n<\/tbody>\n\n<\/table>\n\n<\/div>\n\n\n\n

Meanwhile, the FDA’s regulations and the EU’s medical device regulations (MDR) stipulate that permanently legible labels with unique device identification (UDI) codes<\/strong> must accompany certain medical items for the product’s entire lifecycle.<\/p>\n\n\n\n

\n\n
\n\n \n \u26a0\n <\/span>\n\n
\n\n The compliance stakes:<\/strong> A UDI code has to stay readable for the product’s entire lifecycle, not just until the next autoclave run. A mark that fades mid-life puts the device out of compliance.\n\n <\/div>\n\n <\/div>\n\n<\/div>\n\n\n\n

So medical device companies<\/a> and medical facilities that want to maintain compliance need an effective solution that will endure cleaning cycles and maintain full legibility \u2013 enter black laser marking.<\/p>\n\n\n\n

Cold Black Marking with Ultrashort Pulse Lasers<\/h2>\n\n\n\n

Black laser marking uses ultrashort pulse lasers, or USPL<\/a>, operating in the range of picoseconds (one trillionth of a second) to femtoseconds (one quadrillionth of a second).<\/p>\n\n\n\n

How It Works<\/strong><\/h3>\n\n\n\n
\n\n\n\n\n\n\n\n\n
\n1\n<\/td>\n\n\nThese short pulses don’t simply burn a surface \u2013 they restructure it<\/strong>.\n<\/td>\n<\/tr>\n\n
\n2\n<\/td>\n\n\nSince the pulses are so short, the process is virtually “cold”<\/strong>.\n<\/td>\n<\/tr>\n\n
\n3\n<\/td>\n\n\nThe lasers create periodic nanostructures<\/strong> on a material’s surface, trapping and absorbing light so that marks of a deep, matte black color are produced.\n<\/td>\n<\/tr>\n\n<\/tbody>\n\n<\/table>\n\n<\/div>\n\n\n\n
