Curing Mac mini M4 FOMO with 3D printing (christianselig.com)
If you’re anything like me, you’ve found the new, tinier Mac mini to be absolutely adorable. But you might also be like me that you either already have an awesome M1 Mac mini that you have no real reason to replace, or the new Mac mini just isn’t something you totally need.

Is 3D printing being held back by an invalid patent? (ycombinator.com)
Parts made using the FFM (FDM) process are stronger in some directions than in others. This is due to imperfect adhesion between printed layers. This directional or anisotropic structural strength is a significant limiting factor for the structural integrity of 3d printed parts made with the common FFM process.

Ask HN: Why did consumer 3D printing take so long to be invented? (ycombinator.com)
Today I saw an old paper printer, it has all the pieces for 3D printing except the plastic. Computer sends it data, it moves in 1D to print the image on paper using ink. A 3D printer is just 3 of these moving pieces from a paper printer with a melting plastic and thin pipe and software to connect it all.<p>All the pieces existed to make a working 3D printer existed even in 1970! and relatively cheaply.

Hobby CAD, CNC machining, and resin casting (2015) (coredump.cx)
I'm a computer geek by day, and an occasional hobbyist robot builder by night. For most, the craft of robotics requires either deep pockets, or a combination of outstanding manual skills and easy access to a top-notch machine shop. Because of this, many urban-dwelling enthusiasts tend to give up, resort to expensive and limiting premade kits, or fall back to junkyard-quality engineering.

Man-in-the-Middle PCB Unlocks HP Ink Cartridges (hackaday.com)
It’s a well-known secret that inkjet ink is being kept at artificially high prices, which is why many opt to forego ‘genuine’ manufacturer cartridges and get third-party ones instead.
