Laser system and 3D printers for medical sector - SISMA S.p.A.

Innovation that is good for you

SISMA offers an articulated and advanced series of production solutions, specifically studied for the medical and dental sector: integrable laser sources, laser systems for welding, marking and engraving that meet every medical requirement.


Since their inception, laser systems have been a major contributor to the successful creation of all types and sizes of medical devices. From surgical to implanted devices, marking with laser can ensure that parts are identifiable, non-corrosive, and non-toxic.

Most medical equipment usually goes through a process of chemical passivation, creating a surface film over the equipment that enhances its inherent corrosion resistance, preventing corrosion while also making it less susceptible to germs. One of the major benefits of medical laser marking technology is that it can mark instruments without causing any harm to the chemical coating. The marked surface retains its corrosion resistance even after being continually used, cleaned and sterilized for years.

Marking of medical and dental devices is necessary to ensure that they are easily identifiable and reusable with permanent, accurate and legible markings. Laser marking with unique device identifiers (UDIs) is intended to improve patient safety, simplify post-market surveillance and promote innovation.

Lasers also provide quality assurance, safety and speed of production when welding surgical and medical devices. Laser welding enables microscopic precision and a high melting depth of the material without causing excessive heating or deformation. Some application areas where it is preferred are

  • Dentistry, oral and maxillofacial surgery (welding of dental instruments, dentures and other small elements)
  • Surgery and microsurgery (welding of surgical instruments, welding of medical probes, welding of orthopaedic prostheses…)
  • Laboratory instrumentation (welding of various types of medical and scientific equipment)
  • Chemical instrumentation (welding of fittings, brackets, small precision structural joints)
  • Pharmaceutical instrumentation (welding of pharmaceutical equipment in general)

Sisma also offers a wide range of laser marking and welding systems for medical and dental equipment. Pacemakers, defibrillators, guidewires, catheters, hearing aids, orthodontic appliances, prosthetics and surgical instruments are just some of the many successful applications that have been marked and welded using our laser systems.
