Direct Part Marking with Lasers

Ever try to scan a paper barcode that is faded, creased or torn? It’s not just difficult—it can be downright impossible. That’s why many manufacturers are dropping paper and switching to direct marking systems, which apply information permanently to the part.

Identification barcodes and two-dimensional codes (2D holds more data) on parts are becoming more and more common for safety issues, government and state regulations, and reliable tracking throughout the part’s life cycle.

If you’ve thought about moving up to a direct marking system but aren’t quite sure where to start, this article will give you a basic overview of one of the more high tech methods on the market—lasers.

A laser marking system—a specialty of GT SCHMIDT—is a non-contact form of engraving that is permanent but easy on delicate parts. It is commonly used for part identification and product traceability information such as serial numbers, date codes, 2D data matrix, barcodes, manufacturing codes, material flow, graphics, logos and more.

At GT SCHMIDT, we offer three types of laser marking machines: Fiber, CO2 and DPSS (Diode Pumped Solid State). Each has its own application and benefits. Let’s take a look.


Fiber laser marking systems significantly minimize the stress and potential damage to parts such as those made of metal or plastic. This technology is optimal for many industries, including aerospace, medical, automotive, firearms, dental and electronics.


Fiber laser technology features high levels of power, reliability, quick setup, flexible programming and precise control in an extremely compact footprint. Its high output power gives superior performance in terms of speed and engraving depth. Learn more.


DPSS lasers are used in virtually every market segment including automotive, solar, electronics, packaging, oilfield, heavy equipment, medical and more. Our diode laser systems mark cleanly, clearly and accurately on a wide variety of materials such as metal, glass, plastic, ceramics, silicon and organics.


DPSS lasers have a shorter pulse duration which makes them ideal for sensitive marking applications such as annealing or fine surface engraving where a very small amount of material—such as surface paint—is removed. Learn more.


CO2 laser marking systems are best used for applications of marking paper, cardboard, textiles and other organic materials. This makes them ideal for industries such as food, pharmaceutical and electronics.


Our CO2 laser system offers extreme flexibility for integration of both stand-alone marking stations as well as inline production. Data can be input manually, bar code scanned, or downloaded from your mainframe computer or network. Learn more.


Our laser marking systems offer high processing speeds and consistent high quality marks with equipment that requires almost no maintenance and can be operated with our easy-to-use Windows-based laser software. They can be installed in a safety certified enclosure or in an open environment. Safety certified cabinets are available in standard models or completely custom built to your part size and application needs.

GT SCHMIDT was founded in 1895 and offers the largest and most complete range of marking equipment in the industry.
