\nI worked on the think|haus<\/a> one. Didn’t get any of the final stamp, but here’s some work in progress.<\/p>\n

We used natural linoleum sourced from Mixed Media<\/a>. Important note: don’t use softoleum or other non-linseed oil based “linoleum”! These tend to be made of PVC which will make nasty gases when you laser it.<\/p>\n

Ideally you’d get… stamp rubber… made for lasering… as our laser was designed to work with. But I had no luck finding that anywhere in store and didn’t have enough time to wait for it to be delivered.<\/p>\n

\"Note:<\/a>

Note: remember to mirror your image before you make it into a stamp…<\/p><\/div>\n

You can see here what one of the issues is with using linoleum or possibly my assumed kerf thickness: you don’t really get rid of all the material, you just sort of char it and leave lines there.<\/p>\n

That’s why I ended up going for a stamp that didn’t have a lot of negative space. The one cut out above is basically what we used, except with the whole thing mirrored so it would actually work as a stamp.<\/p>\n

Also, linoleum is super flammable! So, you know, don’t leave your laser unattended. Not that you were going to do that, right? Right.<\/p>\n

Air assist would make this way way<\/em>\u00a0easier – in fact, I cut some at site3<\/a> and they worked so much better. No charring, just material\u00a0gone<\/em>. Magical.<\/p>\n
