Precision Laser Cutting Applied in Medical Parts Production

For decades, lasers have been a well-established tool in the development and production of medical parts. Here, in parallel with other industrial application areas, fiber lasers are now gaining a significantly increased market share. For minimally invasive surgery and miniaturized implants, most of the next-generation products are getting smaller, requiring extremely material-sensitive processing — and laser technology is the ideal solution to meet upcoming requirements.

Precision thin metal laser cutting is an ideal technology for the specialized cutting requirements found in the manufacturing of medical tube tools and components, which require an array of cut features with sharp edges, contours, and patterns within edges. From surgical instruments used in cutting and biopsy, to needles containing unusual tips and side wall openings, to puzzle chain linkages for flexible endoscopes, laser cutting provides higher precision, quality, and speed than traditionally used cutting technologies.

Medical industry challenges

The medical industry presents unique challenges to precision parts manufacturers. Not only are the applications cutting edge, but demanding in terms of traceability, cleanliness, and repeatability. Golden laser has the equipment, experience, and systems in place to provide our customers with the highest quality products in the most reliable and efficient manner possible.

Laser cutting benefits

The laser is ideal for medical cutting, because the laser can be focused down to a 0.001-inch diameter spot size that offers a fine non-contact “tool-less” cutting process at high speed and high resolution. As the laser cutting tool does not rely on touching the part, it can be oriented to make any shape or form, and used to make unique shapes.

1.No part distortion due to small heat affected zones

2.Intricate part-cutting ability

3.Can cut most metals and other materials

4.No tool wear and tear

5.Fast, inexpensive prototyping

6.Reduced burr removal

7.High speed

8.Non contact process

9.High precision and quality

10.Highly controllable and flexible

For example, laser cutting is an excellent tool for small tubes, like those used for cannula and hypo tube applications that require an array of features such as windows, slots, holes and spirals. With a focused spot size of 0.001-inches (25 microns), the laser offers high resolution cuts that remove the minimal amount of material to enable high speed cutting according to the dimensional accuracy required.

Also, since laser processing is non-contact, no mechanical force is imparted onto the tubes – there is no push, drag, or other force that might bend a part or cause flex that would have a negative impact on process control. The laser can also be precisely set during the cutting process to control how hot the work area gets. This is significant, because the size of medical components and the cut features is shrinking, and small parts can heat up quickly and might otherwise overheat.

What’s more, most of the cutting applications for medical devices are in the thickness range of 0.2–1.0 mm. Because the cut geometries for medical devices are typically complex, fiber lasers used in medical device manufacturing are operated often in a modulated pulse regime. The peak power level must be significantly above CW level to reduce residual heat affects through more efficient material removal, especially in thicker cross-sections.


Fiber lasers are continuously substituting other laser concepts in medical device manufacturing. Former expectations, that cutting applications will not be addressable by fiber lasers in the near future, had to be revised quite a while ago. Therefore, the benefits of the laser cutting will contribute to the tremendous growth in the use of precision cutting in medical device production and this trend will continue in the coming years.
