This page contains a list of materials that can be cut or engraved on the 'NEW' Nottinghack A0 laser cutter from Just Add Sharks, along with information on cutting speeds and power settings.

You can see a reasonably complete list of what is laser safe [http://www.cutlasercut.com/laser-cutting-materials-laser-engraving-materials here] and [http://www.atxhackerspace.org/wiki/Laser_Cutter_Materials here].
There is usually a small supply of laser-safe perspex (acrylic), mdf and ply available for sale next to the laser cutter, up to 600x400mm in size. A wider selection of sizes, colours and thicknesses is available online, although the stock in the 'space is sourced from [https://www.kitronik.co.uk/ Kitronik], which is based near the Glaisdale Royal Mail depo in Nottingham.

350 power, 12 mm/s gives a nice clean cut.  If there are knots in the ply it may not cut all the way through, you can reduce the speed to 14mm/s to compensate for this.

400 power, 200mm/s with Bottom Depth = 1 and Top Depth = 250 gives a nice image with a black depth of around 0.5mm and white depth of 0.  This will require sanding afterwards.
Anodised aluminium can be etched (removing the anodising) at 20% power, 600mm/s. This has not been thoroughly tested, so be prepared to experiment.
 
At 350 power but all the other settings the same, the black depth is around 0.35mm.  This will work fine for high contrast images.

Introduction

This page contains a list of materials that can be cut or engraved on the 'NEW' Nottinghack A0 laser cutter from Just Add Sharks, along with information on cutting speeds and power settings. There is a more complete list of materials pinned above the laser computer, although you should be aware that this list does not contain every material known to man, so will be incomplete. If you are uncertain as to whether a material is safe to use, first look up it's material safety data sheet (MSDS), which should be available online, and/or ask on the Google Group or #laser channel on the Nottinghack Slack.

You can see a reasonably complete list of what is laser safe here and here.

There is usually a small supply of laser-safe perspex (acrylic), mdf and ply available for sale next to the laser cutter, up to 600x400mm in size. A wider selection of sizes, colours and thicknesses is available online, although the stock in the 'space is sourced from Kitronik, which is based near the Glaisdale Royal Mail depo in Nottingham.

The values on this page have been tested, but are guidelines. Always stay with the laser when it is running, and use your common sense!

DO NOT CUT

  • Vinyl, PVC - Contains chlorine, which generates glass and metal damaging acid fumes when burned!
  • Polycarbonate - clear polycarbonate looks just like acrylic!
  • Anything that produces fumes, e.g. glued woods (except laser-safe MDF/ply), many types of plastic.

Wood

Greyscale Engrave

Monoscale Engrave

Cutting

Type Power Speed
3mm birch ply 65% 55mm/s
3mm birch ply 65% 55mm/s

Veneer

Paper and Card

Go fast and run test cuts! Then help us by documenting what worked for you.

Plastic

Acrylic/Perspex

Type Power Speed (mm/s)

Metal

Anodised aluminium

Anodised aluminium can be etched (removing the anodising) at 20% power, 600mm/s. This has not been thoroughly tested, so be prepared to experiment.
