Hier noch eine Kritik an der Metrik des "Erdüberlastungstages" (aber nicht an der Kernaussage): https://www.spektrum.de/news/erdueberlastungstag-fragwuerdiger-fussabdruck/2181516
TL;DR es liegt fast nur am CO2, dafür ist es dort in der Realität schlimmer als die Metrik vermuten lässt. Nicht erneuerbare Rohstoffe werden gar nicht erfasst.
Es geht um die Europawahl. Da gibt es (noch) keine 5%-Hürde.
No one but complete morons are asking to specifically make a product by emitting carbon dioxide. No company is emitting co2 for "the global citizens". They make products to earn money. Emissions are an avoidable by-product no one asked for.
Nein, nur den Energieverbrauch.
- FOR PURPOSES OF THIS SECTION, "THREE-DIMENSIONAL PRINTER" MEANS A COMPUTER OR COMPUTER-DRIVEN MACHINE OR DEVICE CAPABLE OF PRODUCING A THREE-DIMENSIONAL OBJECT FROM A DIGITAL MODEL.
Not an American, but it really reads like they redefined 3D printer as meaning "literally any kind of cnc machine".
!luthier@lemmy.world is woodworking-adjacent and could use a bit more activity.
It does sound more rough and archaic, far less "sweet" than a violin. But that has a lot to do with the setup, less with the body shape. No soundpost, but quite long bass bar. Then the bridge style makes 50% of the sound. This crown shape in the pictures is really harsh. I've replaced it with a rebec style arch bridge (sadly have no photo of it atm), which is better but still distinctly medieval. I also fitted and tried a modern violin bridge, which makes it sound pretty close to a violin!
Please note that vielles are not standardised like modern violins. It's really any violin/viola sized bowed instrument with flat or just slightly arched back and top. This is really just my design loosely inspired by old paintings and modern makers.
Also the hair on the bow has a huge influence on the sound. I rehaired a baroque bow with black horsehair, which is very coarse and gives a rough sound.
Spruce top, the body and neck are carved from a single block of maple. More photos:

It's basically a 10 inch screen matrix for SLA printers, a 130W blacklight lamp from Amazon and a ground glass for even lighting. The lamp gets very hot, so the two fans blow air over and under it (split cooling channel). The parts touching the lamp are printed in Greentec Pro Carbon, electronics box and cooling channel are printed in Geeetech matte PLA.
Printed with greentec pro carbon (stiffest filament I've found so far). 8 perimeters, 45% infill, top/bottom 2mm. The arms are 230mm long. The design and material of the C frame are still not stiff enough to be usable, but I'm pretty proud of the lever design. Easy to put together, durable and doesn't wiggle to much.
Schon zur Einführung der Eisenbahn gab es Bauernproteste, weil sie glaubten, dass die Eisenbahn mit ihrer atemberaubenden Geschwindigkeit (etwa 30km/h) die Kühe verrückt machen würde. Die Zeiten ändern sich, die Menschen aber nicht.
