Micromachining With A Laser | Hackaday


[Breaking Taps] has a nice pulsed fiber laser and determined to attempt it to micromachine with silicon. You can see the outcomes in the online video underneath. Silicon absorbs the IR of the laser perfectly, whilst the actual physical properties of silicon go away something to be ideal. He also is still refining the procedure for steel, copper, and brass which may well be a bit extra simple.

The laser has pretty limited period pulses, but the pulses have a fantastic offer of vitality. This was experimental so some of the assessments did not perform pretty very well, but some — like the gears — appear good.

This most likely isn’t going to do the job with your $200 Chinese laser engraver. But if you do have the right form of laser (his is a generic a person that runs about $4000-$6000), the recommendations about focal length and timing will possibly help save you some experimenting on your individual.

We have to confess we were a bit jealous. Not only does he have accessibility to a quite great laser, but he also has entry to a scanning electron microscope which is of greater high-quality than the kinds we utilised to use and we really do not even have access to these any longer. You can see a great deal of assessment of the sections carried out under the SEM in the online video.

If you are looking to justify the charge of a fiber laser, they do make dandy PCBs. We’ve even noticed a small of how these lasers get the job done internally.
