    ... got recently some high-power laserdiodes with 200Watts@976nm on a spot of 0.2mm, so enough power and enery density for all sorts of metal-work (sintering, soldering, welding, cuting, ...).

    Actually building drivers and controllers for "additive metal wire fusing", but could be easier for powder, than for wires.

    Here a thread showing first experiments with the 200W-diode - https://reprap.org/forum/read.php?133,235148,page=5

    Holy crap! Got pictures or video of this one? I'd love to see that!

    yes I do. I'll have to find them or i'll just take new ones. It's not what you are thinking. It's functional in the sense all the parts are there but it's plastic. You turn the shaft by hand and the valves and such operate. no oil no gas....
    I wanted to do a metal one that runs but never got there. The r2800 9 cylinder is the model.

    some examples: https://www.thingiverse.com/search?q...35d10ebc70621c

    Not sure which one I downloaded.

    hey ryan https://gizmodo.com/making-custom-gu...ing-1728210366

    Use ethanol as the solvent....

    Actually that's exactly what I was thinking. I've seen a few videos on Youtube, but they were from well-financed content creators with lots of subscribers and millions of views on each of their videos. It definitely did not look easy.

    Curious how the assembly process went for you?

    Assembly was easy. Ill toss it in the car for selem so you can see it in person. Photos on way. Sorry so dark.

    ... hmmm ... not enough "bandwidth" for more brightness -- but here, slightly better visible

    WOW! That is a lot more detailed than I expected!

    And thanks for increasing the brightness Viktor; it made a big difference.

    Please do bring this to SELEM. I know a few other people who will also want to see this.

    It's pretty fragile. I'll decide if I want to chance it just before. The parts took over 100 hours to print. assembly took a few months. The push rods are all hand formed metal. springs handformed. THAT was not fun.
    Here's what I REALLY wanted to do. https://www.youtube.com/watch?v=Y1rjRmTV9qE https://www.youtube.com/watch?v=aOexZOxw2HU

    This much I did do. https://www.youtube.com/watch?v=HGKXdYCksAQ

    was a fairly early adopter when the printers were more expensive and the reprap project was in an early stage.. my 3D printer was of steel rods and laser cut wood.. which wasn't that strong and able to rust but it worked!
    Eventually i build another one and rebuild the old one a bit.. glass heated beds sucked.. especially when the glass was slightly curved!

    Nowdays im very happy with my prusa mk2s and looking to upgrade to the mk3.. its not hands off but quite reliable and the prints are very nice.
    I'm going to get an SLS printer eventually but i held off because of cost and availability of the resins... especially ones that go further then just being nice looking models.. it is only usefull if you cast them out of a stronger material and the more practical and strong resins were hard to get at the time. But yes they are very valuable machines if you make models yourself!
