... 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 ...
... and here an older lasercut miniature flying buttres(?):
Those are beautiful! Nice detail. Good work!
Very detailed! Job well done.
... 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:
... 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:
... and a video cutting it with a 'pulsed' blue 3W-diode - https://vimeo.com/175801655
... 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:

... 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:

- coat/stick red and white partially for the text:
... cut the text and engrave the logo on plain eloxal:
- nearly done:

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.
... with blowing the fumes away you will avoid traces, but then you have all the fumes in the air, what's much more problematic.
Precoating the surface with a peel-off (I'm actually using sticking tape) helps for cutting, but it will give unpredictable results with engraving.
There are some more possibilities with bigger focal distances, but with this diodes I'm avoiding more than 30mm distance for better/smaller focus diameter and shape.
With the fiber-lasers I'll get up to 150mm focal distance and can remove the fumes without any traces -- but with the shorter distances with diodes it's all more like testing materials and best methodes for "complex" applications
... making sticky labels with transfer-film:
... Christmas is on the way -- this time I'm testing with some laminating or 3D designs.
Here a video cutting the layers:
And the results ...
... new 3D type vs. older plain style:

... 3D in detail (it's much more impressive in real view):

... and then all the spacers, needed for stacking the 3D snow-flakes:

... and here a "serious 3D"-snowflake for relatives in Frankfurt on the Main - the 3D-scene shows the bridge "Eiserner Steg":

... changed the design for better visability:

... here a 2D-design again for a friend from Bad Orb with the coat of arms:
