Wild times when running a 3D printer feels easier than dealing with those old 2D ones. 😎

Probably the most unrealistic print I've done to date. Small test of Ultraglow and PETG Ultramarine Blue while using color mix and shading. Feels like I'm holding a hologram. Definitely going to work on some more projects in this line. #3dprinting #prusa

Galaxy Black TPU FTW!
Prusament TPU 95A is now available in Galaxy Black! 🖤 Tough, flexible, and easier to print than most flex materials, it’s a great choice for grips, RC tires, protective covers, phone cases, and anything that needs to bend, stretch, or take a hit. prusa3d.com/product/prusamen…

Its official. The Pixel Pump 2 is coming 🔥 Will do a proper introduction video soon but here's a few interesting specs 🧵 (It's a tool for PCB hand assembly)

Can you receive FM radio on a 3D printer's heatbed? @repkord asked, and we tested, with some assistance from my Dad, a radio engineer! The answer is yes, and a video is here: youtube.com/watch?v=BA3_jCst…

I looked at those slicers too... CWE-494 isn't just a Creality issue. It is inherited directly from OrcaSlicer, and all the other vendor forks have it too. This means Bambu can inject its own code into all of these slicers. That might be a good reason to submit a PR to @real_OrcaSlicer adding integrity checks, but someone would have to maintain it... What is unfortunate is that all these vendors forked OrcaSlicer, yet apparently none of them contributed anything back. At the same time, they all modified the cloud opt-out / libbambu_networking behavior. Creality completely removed Stealth Mode from the UI. Elegoo commented out the control toggles. FlashForge left the option in the UI, but commented out and disabled the backend!!!, so the setting does nothing. Anycubic added its own networking stack, and the setting does not apply there. Another interesting detail is that the official Anycubic package does not fully match the GitHub source code. It contains 13 additional binaries, and they also removed the Orca-branded models. 🙂 CrealityPrint has very aggressive telemetry. It sends more than 70 different events to a Chinese SaaS platform, Sensors Analytics / 神策, (IMHO) without clear consent. They claim the data is anonymous, but it includes permanent identifiers such as device_id and user_id, along with information about printed models, other printers, and much more. On top of that, the privacy dialog seems to almost never appear. As for libbambu_networking (used by all vendors), the slicers expose the user's public IP address, the slicer itself, and its usage frequency to Bambu. Once a user logs into MakerWorld (I am not sure all users realize this is Bambu) it can link that to their identity, full printer information, what they print, and their slicer settings (amazing marketing source). Bambu can also silently push arbitrary code to your computer via the libbambu_networking update and execute it when the slicer launches.

Byl jsem se podívat v továrně Citroënu ve Francii a zaujala mě tahle budka „Kaizen 3D“ s tiskárnami od Průši přímo na lince, vedle oddělení pro EV baterie. Tisknou si tu zlepšováky pro výrobu C5 Aircross, třeba kontrolní šablony pro zámky kufrů, za zlomek ceny proti původním postupům. Haly tu jsou sice staré, ale linky mají méně lidí a více robotů než průměrná čínská automobilka. Jenže využívají sotva čtvrtinu kapacity, a tak se tu ještě letos začnou vyrábět i Dongfengy...

It uses OpenPrintTag material data and is MIT licensed so the community can play with it and build on it. ✨ Read more in our new article: blog.prusa3d.com/our-new-ope… 2/2

On large boards with 8 or more signal layers, it´s important to place all (or as many as possible) layer transitions early in the layout phase, ideally after the component placement. Especially if only through VIAs and VIAs with backdrilling that require a bit more clearance are used. This design contains 16000 pads, any layer transition that needs to be placed during the routing phase might require a lot of cleanup time on the inner layers to make room for VIAs

😬 Tohle je největší noční můra. I když má paraglidista přednost (nemá motor), tak o důvod více mít sebou FLARM apod. PS: Pilotka PG prý přistála na záložáku a je OK. 🪂 Stejně tak pilot Cessny přistál na nejbližším letišti a je OK. 🛩
🚨 WATCH: A paraglider gets hit by a Cessna 172 near the Austrian town of Zell am See. The paraglider was able to pull her rescue parachute and land safely shortly after the incident on Saturday. According to police, the 44-year-old Austrian had started from Schmittenhöhe in the direction of Piesendorf. Above the Pinzgauer Hütte, she collided at 1:15 p.m. with the Cessna piloted by a 28-year-old. The pilot of the Cessna, which flew from the Glemm Valley in the direction of Zell am See, was able to land the aircraft safely at Zell am See Airport. Video: sab_thi
