... some parts for Christmas

[VDX]

... 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 ...




... and here an older lasercut miniature flying buttres(?):

Those are beautiful! Nice detail. Good work!

[KANG]

Very detailed! Job well done.

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

It's beautiful.

... 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:




... with:




... and ready:





... and here the older poplar-part in foreground and one cut from cardboard in the back:

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







- best to cut is sponge rubber:

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





And then a sample from poplar plywood - first the engraving (with some fume traces):





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





- from the back:





- ready:

... I had to change some samples for the next fair - here the steps for multicolor laser-marking

First - stick complete blue and cut for the border:




... cleaned:




- coat/stick red and white partially for the text:




... cut the text and engrave the logo on plain eloxal:




- nearly done:




... ready:

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.
