laser cutting and engraving tests.

We booked the laser cutter in the fab lab this morning. We tested cutting and engraving with a selection of shapes and line sizes. It worked really effectively. the only issue we had was that the dust leftover from the engraving was easily smudged, leaving black marks on the leather and ruining the crispness of the lines. We tried removing the marks with a rubber eraser - this worked on the surface of the leather, but as soon as it got near the engraved lines/shapes it ruined the colour as seen in one of the images. if we had a setting/sealing spray that we could use on the leather after engraving to avoid this it would be good.
