It trains on images of normal prints, flags deviations, and can automatically pause a print through the Moonraker API after repeated anomaly detections. The system can also integrate with OctoPrint, send MQTT notifications to Home Assistant, and operate entirely on the local network for privacy and security. ### Source excerpt A lot of newer 3D printers incorporate sophisticated sensor suites and cameras to detect problems with print jobs, like the dreaded "spaghetti failure." Those work pretty well and prevent wasted time, wasted filament, and even damage to the printer. But what if you don't have a printer with those features? Or if you want to [...] The post Turn Arduino® UNO™ Q into your local 3D printing watchdog appeared first on Arduino Blog. ## Petoi Quaddle - A mini robot dog for physical AI experimentation (Crowdfunding) DevFeed: [Petoi Quaddle - A mini robot dog for physical AI experimentation (Crowdfunding)]() Original publisher: [Read original article]() Author: Jean-Luc Aufranc (CNXSoft) Published: 2026-09-04T08:03:49Z Content type: news Language: en Sources: [CNX Software - Embedded Systems News]() Topics: [Robotics](), [Physical AI](), [ESP32-S3](), [Arduino](), [Raspberry Pi](), [coding](), [Open Source]() Tags: [3d-printing](), [arduino](), [broadcom-bcmxxxx](), [c-c-plus-plus](), [crowdfunding](), [edge-ai](), [education](), [esp32](), [esp32-s3](), [esphome](), [espressif](), [hardware](), [micropython](), [open-source](), [physical-ai](), [raspberry-pi](), [robot-dog](), [robotics](), [ros](), [simulator](), [smart-home](), [smart-speaker](), [stem](), [video]() ### AI overview The Petoi Quaddle is a mini robot dog designed for learning robotics, coding, physical AI, and 3D printing.

It supports simultaneous duplicate printing, multi-color and multi-material printing, and batch production, with claimed toolhead changes in one second, near-zero purge waste, motion precision of ±1µm, and speeds up to 500 mm/s. ### Source excerpt The LightMake L4 is a desktop 3D printer with four independent printing heads for high-throughput multi-color, multi-material, and batch production. It uses four independently controlled printheads and linear-motor motion instead of conventional belts, allowing users to print four identical models simultaneously, produce complex multi-color parts with minimal purge waste, or combine up to four materials in a single print. Typically, multi-color FDM 3D printers like the Bambu Lab X1 or Geeetech A20M use a single-nozzle purge material during every color change, which leads to a lot of material waste and longer print times. The LightMake L4 takes a different approach by keeping four filaments loaded and heated in four completely separate extruders. According to the company, this allows for one-second toolhead changes and near-zero purge waste. The linear motor system also promises ±1µm motion precision and speeds of up to 500 mm/s.

(Pixel Art Robot), a 37 x 18 flip-squisk display that uses a servo-actuated robot controlled by an Arduino Nano ESP32 to flip 3D-printed square discs and render monochrome pixel art. A color sensor detects each disc's state, and an internet-connected website lets visitors submit images for display. ### Source excerpt Flip-disc displays used to be very common in the days before affordable LEDs, LCDs, and OLEDs. But as electromechanical devices with a lot of moving parts, they're expensive and rare today. That's a shame, because they're charming. That charm is what led Zimm to the creation of this novel flip-squisk display called P.A.R (Pixel Art [...] The post P.A.R. is a flip-squisk display that draws your pixel art appeared first on Arduino Blog. ## Tuning in FM Radio on a 3D Printer Heatbed DevFeed: [Tuning in FM Radio on a 3D Printer Heatbed]() Original publisher: [Read original article]() Author: jeff@jeffgeerling.com (Jeff Geerling) Published: 2026-05-28T14:00:00Z Content type: opinion Language: en Sources: [Jeff Geerling]() Topics: [3D](), [Nanovna]() Tags: [3d](), [3d-printer](), [3d-printing](), [fm-radio](), [geerling-engineering](), [nanovna](), [pcb](), [radio](), [rf](), [sdr](), [signal](), [video]() ### AI overview The article tests whether a 3D printer heatbed can act as an FM radio antenna. Measurements with a NanoVNA found several potentially suitable frequencies, although the heatbed traces are not optimized for radio-frequency use. Near a high-power FM tower, the heatbed received a clear stereo signal. ### Source excerpt Pooch from Repkord dropped by my studio while he was in St. Louis, and asked a simple question: Can a 3D printer's heatbed act as an antenna? A fair question, as many an antenna is embedded in a PCB these days... and the traces on a PCB heatbed like the one used in Prusa's Core One look kinda like an antenna, if you squint the right way. Really, anything (or anyone) can be an antenna, given enough power. ## SpaceDeck X is coming to an arcade cabinet DevFeed: [SpaceDeck X is coming to an arcade cabinet]() Original publisher: [Read original article]() Author: Stanko Published: 2026-05-21T00:00:00Z Content type: release Language: en Sources: [Stanko Tadić]() Topics: [arcade](), [3D](), [JavaScript](), [pixel]() Tags: [3d](), [3d-printing](), [game](), [javascript](), [pixel-art](), [release](), [steam]() ### AI overview The article announces that SpaceDeck X will be released on a physical arcade cabinet at Blast Galaxy in Amsterdam on June 14, with a release party and high-score tournament.

I'm actively working towards a Steam release, so stay tuned! ## 3D-Printed Frame Repairs a Broken Bunny Brooch DevFeed: [3D-Printed Frame Repairs a Broken Bunny Brooch]() Original publisher: [Read original article]() Author: Stanko Published: 2025-02-23T00:00:00Z Content type: opinion Language: en Sources: [Stanko Tadić]() Topics: [3D]() Tags: [3d-printing]() ### AI overview The author describes repairing a broken bunny ski-jumping brooch by designing and 3D-printing a frame that holds its broken pieces together. They traced a photo in Inkscape, extruded the outline in TinkerCad, and tested several prints until one achieved a tight press fit. ### Source excerpt I love 3D printing. It feels like magic - we are able to design and create physical things in a matter of hours, in our homes. I understand the underlying technology, but it still blows my mind when I think about it. It makes me a bit sad that more people aren't fascinated by it. Let's see what my love for 3D printing has to do with bunnies. Ski jumping bunnies to be exact. My wife has a brooch that she really likes - of a bunny ski jumping. She wears it on her backpack, and when she's in the mountains, on her ski jacket. But unfortunately it broke - the skies snapped off. So she asked me, Can you fix it somehow? Maybe 3D print something? This was right up my alley. After some thought, I decided the best approach would be to design a frame for the broken pieces, with slightly offset edges to keep them in place. But how could I design it when the outline was so irregular? After overthinking it, I returned to a simple solution - I took a photo of the brooch, imported it into Inkscape, and traced it by hand. Here is the result: I extruded the outline using TinkerCad and did a test print. I was pleasantly surprised, because the print was almost perfect. There were a few points that needed tweaking, but before making changes, I wanted to see if simply adding an edge would work. And it did! To be fair I printed four in total. I'm a bit embarrassed to admit, but I printed the first one mirrored. Then printed three more with slightly different measurements for the offset and edge height. One of them fit perfectly. And I mean - perfectly - it is a very tight press fit. Oh joy! Bunny bunny jumps again! My wife was thrilled to see her favorite brooch fixed. But the real point I wanted to share is that 3D printing is amazing, and sometimes, the simplest ideas work best! ## Should robots be building our homes?

I hope you can tell from my ACM Queue column that I like to do a lot of research and I tend to want the best thing. I had been keeping my eyes on the 3D printer product space for quite some time. This article is going to go over the technical details behind 3D printing as well as my experience with two different products. When I finally decided to buy a 3D printer, I wanted to try ones that used different additive manufacturing processes: material extrusion via fused deposition modeling (FDM) and vat polymerization via stereolithography (SLA)1. While I would have loved to have gotten a printer for each of the seven different additive manufacturing processes, I did not. However, I did dig into the details of all the various additive manufacturing processes and technologies. Let's dive in! If you would prefer to skip the research you can jump down to the review. Additive Manufacturing Processes Popular culture uses the term "3D printing" as a synonym for additive manufacturing processes. In 2010, the American Society for Testing and Materials (ASTM) group "ASTM F42 - Additive Manufacturing", formulated a set of standards that classify the range of additive manufacturing processes into seven categories2. The processes vary on the material and machine technology used which has effects on the use cases and applications as well as the economics. Material extrusion Material extrusion defines a process where an object is built by melting and extruding a thermoplastic polymer filament in a predetermined path layer by layer. Imagine if you were building an object and the only material you could use is a tube of toothpaste. You'd slowly build the walls of the object by putting layers of toothpaste on top of each other. Material extrusion is similar. Material extrusion devices are the most commonly available and the cheapest types of 3D printing technology in the world. It represents the largest installed base of 3D printers glob
