You know, honestly, more than monetary donations, if somebody worked at a company that had access to a lot of 18 terabyte and larger hard drives and could talk to us, that's where we are really suffering. The internet archive has no special priority in buying hard drives and those things are insane.

Maybe it seems weird that AI bosses won't stop rending their garments about the terrible potential of their bots, from the jobspocalypse that'll ensue when AI does our jobs, to the impending moment when the word-guessing programs learn too many words, wake up and turn us into paperclips. 1/

The "Serenity Prayer" (*Serenity to accept things I can't change/Courage to change the things I can/Wisdom to know the difference*) is usually cited as pop psychology or addiction recovery advice, but I think there's a place for it in policymaking. 1/

Wow after years of asking for it, Prusa has finally added the CERN OHL v2 license to printables ... but only the stricter variant 🙄 CERN OHL v2 is the only modern open source license protecting your functional 3D prints. It has 3 variants: strong, weak and permissive. #3dprinting #prusa

For one of my clay printers, moving from 24v to 36v and upgrading the control board from the Duet2 to the Duet 3, which will then connect to the RaspberryPi. Will allow more power to reach the clay pushing motor and will make it easier to connect, add features like camera, remote monitoring, etc.

I made a tool that turns PCB designs into 3D-printable molds. you sandwich copper tape between the parts, sand the ridges, and you have a real working PCB. no etching, no chemicals. I am losing my mind castpixel.itch.io/pcb-forge
I printed it and stuck self-adhesive copper tape to it. There's copper tape with conductive adhesive so you can add multiple overlapping pieces and it counts as one conductive surface.

Then I used the second part of the mold to shape the copper, so that it sticks inside the recessed traces.

Then I used sandpaper to file away at the raised ridges. The copper traces are now electrically independent of each other. Done!

But if I want, I can remove the extra copper tape.The companion mold at the bottom. This second 3D-printed part pushes the copper tape down into the recessed trace channels so it conforms to the shape. The two parts sandwich together with alignment spikes to keep everything registered.screenshot of QZW Labs' raised pcb idea! here is their youtube video

preFlight is a new open source slicer based on #PrusaSlicer but with deep rework of its internals. - Truely 64bit - GCode processing in memory - Athena algo improving over Arachne - Interlocking perimeters similar to brick layers - Deeper #RRF integration ➡️ github.com/oozebot/preF... #3dprinting
preFlight logo. Similar to the Slic3r logo but with light blue and orange color and a rocket crossing it.Showcase of the Athena perimeter generator compared to Arachne. The perimeters are better filled and more regular.Table comparing Brick Layers with interlocking perimeters. The mechanism of this new slicer is based on X/Y variations and over-extrusion to compress plastic between the voids while. Brick Layers is based on Z variation. It claims 5 to 15% strength increase.

If you’re a 3D printing designer you should be upset about this. Companies can slip through a bogus design patent on your model and block you from distributing or monetizing it. This would take away one of the only options for fighting that that’s even remotely affordable

DasFilament announced a recycled PETG filament made from waste of Film production. This rPETG has the same properties of their standard PETG and is specifically designed to have unique colour changes. Available in spools and refill. ➡️ www.dasfilament.de/filament-ref... #3dprinting #dasfilament
A refill spool of rPETG in the center of a white page with colour changing in the violet range. On top the title a title in black "Recyceltes PETG" A close up of a refill rPETG spool on white background. We can see the color changing from brown to black to violet. A text in German with four spools in the background. Deepl translates the text in English as follows:
"For a long time now, the waste that inevitably arises during film production has been a thorn in our side. We have now succeeded in recycling this waste and using it to produce filament that is of the same quality as our other filaments." A text in German with a column of rPETG spools in the background. Deepl translates the text in English as follows:
"We design the production of rPETG in such a way that, instead of a uniform "colour paste", unique colour changes are created. We are starting with spools and refills in PETG (1.75 mm). The colours vary and are selected at random for shipping."
