Due to the nature of the medical industry, it’s incredibly important that any products, tools, and equipment are designed with the highest quality of care, safety and precision to deliver clean cuts, smooth surfaces, hermetic joining and micro-welding; all qualities that are found in many medical devices.

Particularly important attributes of our fiber lasers in the medical industry are additive manufacturing, cleaning and marking, we go onto discuss our applications below.

Medical and health industry applications and uses

Additive manufacturing is an important laser function in the medical industry, the ability to rapidly 3D print, parts and shapes in various materials is invaluable. Rapid prototyping, in particular, is already heavily adopted. This enables prototype designs to be created quickly for user trials, R&D and training purposes. Prototyping can also be used to create patient-specific parts (e.g. prosthetics and dental products).

Marking/engraving is a popular application and in the medical industry, this can be on a range of materials such as glass, metal and plastic in particular. Deep marks (i.e. engravings), as well as surface-level marks, can both be fulfilled with a fiber laser. Marks such as serial numbers, part numbers, expiry dates, patient information, etc. can all easily be made on tools, parts and other items.

Marking of QR codes with a laser from SPI, QR codes are frequently used in medical settings

Welding is another popular application, particularly for medical tools and devices. Smooth seams are required, which are sterile and often hermetically sealed. Some devices are implantable (e.g. pacemakers), so the non-contact aspects of fiber lasers are perfect!

Laser cutting is used in many ways, a popular use is in the micro-cutting of stents, which are used in blood vessel surgery. Needle cutting is another example of an application.

The medical industry and SPI Lasers

Fiber lasers are a perfect solution for the medical industry, offering a much higher level of reliability and efficiency than more conventional methods.

In an often-cost-conscious environment, it is reassuring for governmental healthcare agencies and health organisations to know that an investment in SPI fiber lasers is an investment in versatility. Government health agencies, hospitals and health organisations can buy a fiber laser equipped machine and enjoy top-quality ablation, 3D printing, cleaning, cutting, engraving, drillingmarking and welding services. Contact us to investigate what SPI Lasers can do for your medical organisation.
