Laser micromachining for precision medical components

Laser cutting is a key technology that enables the manufacturing of miniature components at micron tolerances, particularly stents and surgical tools.

Beyond Laser uses the ultrashort-pulsed UV laser and high-energy pulses of fiber lasers to accurately cut intricate product designs from tubular and flat materials.

Beyond Laser’s experienced laser cutting technicians maintain a fast and tension-free cutting process working with state-of-the-art laser cutting machines, capable of both dry and wet laser cutting, combined with CNC motion systems. CAD/CAM software directs the appropriate 2, 3 or 4-axes laser cutting process.

Advantages of ultrashort-pulsed UV laser cutting

Maintaining tight tolerance, micron level precision, while accurately cutting complex geometric contours of different thickness.

Cutting a smooth and un-oxidized edge with little dross reduces finishing steps thereby improving overall production throughput.
High peak power vaporizes part of the material while gas pressure pushes liquefied material out, resulting in minimal heat affected zone (HAZ) and thermal damage, e.g.: burrs, slag, and recast.
Precise control over heat input by adjusting the beam diameter (cutting width) and pulse parameters (voltage, pulse width, frequency).

Typical applications for laser sheet cutting are miniature scalpels for eye surgery, plates, filters, optic masks, discs, rings, miniature cog wheels, vacuum nozzles, etc.

Beyond Laser developed special laser cutting techniques for cutting thin metal foils and very fine shims or spacers of 0.005-0.05 mm thickness used for electro-optic calibration.

These techniques enable Beyond Laser to handle and laser cut thin foils without deforming their shape and without thermally affecting them.
