Laser Stamps

This is a guide to making rubber stamps on the laser cutter.

Stuff required

Firstly you will need some laser rubber, which can safely be cut on the laser cutter without loads of fumes. There are only a couple of suppliers in the UK:

I had to buy this in bulk as shipping was quite expensive. Its around £6 a sheet, plus £6 p&p, plus VAT. If you would like a small bit to try then I am selling the excess from mine at £5 for an A6 piece (1/4 A4 - enough to make a load of stamps). Email matt_AT_re-innovation.co.uk.

Laser rubber is pretty boring and looks like this:

You will also need a rubber stamp ink pad and some structure to hold the stamp (a block of wood with a handle).

Make your stamp image

Make your image on your favourite graphics package. The image should be just black and white, as there is no graduated colour on a stamp. Make sure its the correct size. One step to remember is to mirror the image, as it will be printed inreverse.

Export it as a bitmap or jpeg.

Cut out the stamp with the laser cutter

We will be using the laser cutter as a laser engraver (actually thats what this laser machine is).

Import the image into the laser cutter program (The amazingly named 'Newly Draw' in Nottinghack case).

Test it out on a piece of wood - does it look OK? To cut the rubber, the settings I used are: speed 50, power 200. This made a reasonable depth (around 1mm). I would suggest using even slower speed to make it even deeper. I will check next time with just 20 as the speed.

Cut the stamp out with a sharp knife. Any point edges might affect the stamp, so go pretty close to the raised surface.

Glue the stamp onto some wood backing (with handle added). Prime with ink and stamp everything in sight.
