    Default ... some parts for Christmas

    ... for a school event of my youngest son I've cut some deco-art with Christmas motives.

    Here the first results in cardboard ... I'm working on some more complex 3D-parts ...

    ... my wife wished the candle-arch a bit greater and with more 'atmosphere':

    ... at request of my wife I've sketched an "Elk-bow" and lasercut it from 4mm-poplar- and 3mm-balsa-plywood.

    Used a 3.5W@445nm-diode at roughly 2W, pulse/pause-ratio around 50%, 7 minutes per pass, 5 or 6 passes (don't remember exactly) for the poplar, 4 passes for the balsa plywood.

    Here it's cutting without shielding:

    ... I'm lasercutting some samples for the next exhibition - actually some "seals" made from different materials:

    ... made some more samples - first a pretty hard and thick (and hard to cut too) piece of foam material, normally used for shoe-soles:

    - to avoid stronger fume traces when cutting, I previously coated it with adhesive tape:

    try a strong fan to blow the vapor away. That can limit the vapor trails too. I also tried a spray on plastic that peals off but I don't know the name anymore.
