Metal laser cutting

500W metal laser cutter Use by prior agreement only. It can cut up to 6mm steel, 1mm alu, 2mm stainless. It cannot cut brass or copper. The working area is 1300x900mm.

We have recently aquired a semiconductor pump ytterbium-doped fiber laser (single-mode continuous) from Maxphotonics.

This laser can only be used with a Technology Guru. We have limited time. We are still learning to use it effectively. If you wish to use this machine, you must email a motivated application explaining

  • Who you are
  • What your project is
  • Size
  • How much cutting (approx, in distance travelled. There is a big difference between cutting a 1000x500m sheet with four holes in and a 1000x500mm sheet with 900 intricate details. The laser can usually cut about 30mm per second.
  • What materials you will be bringing / that you will be bringing your own materials (Sanistål and Lemvigh Müller are possiblilities.)
  • A couple of suggestions for times, within our opening hours.

  • Please consider weight. Steel weighs about 7800 kg per cubic meter. So for example, something 1000x600x4mm weighs 1x0.6x0.004x7800=19 kg.
  • Steel sheets are often sold in 1x2m size. These are heavy! And need cutting in half before they can fit in the laser cutter.
  • We do not sell materials.
  • Please bring a .dxf file on a USB stick
  • Bring your computer so you can correct any issues.
  • Steel up to about 2mm (1mm for stainless) cuts nicely. Over ~2mm there will be dross on the underside of the cuts, which will need removing with a belt sander or similar.
  • You need about 10mm extra around the edges.
