About a robot that became a 3D printer! 🖨️ A team of designers in Shanghai developed a 6-axis robotic 3D printer inspired by spiderwebs at Tongji University. The project is about merging design and fabrication processes, drawing from spider threads' biomimetic strength and structure. 🕸️ The printer utilizes a unique spindle-knot extrusion technique, enabling self-supporting structures and greater spatial flexibility than traditional layer-based 3D printing. The device features a robot from KUKA and a robotic end-effector with movable printheads, controlled by an Arduino-based system with precise temperature and extrusion controls. Despite being a work in progress, the project shows the potential of combining robotics and 3D printing. ~~ ♻️ Join the weekly robotics newsletter, and never miss any news →

Supportless, free-form 3D printing! ⛓️ By using low-melting-point Fields' metal and shaping it through surface tension, this process can create highly conductive 3D structures in a single pass, no supports, no post-processing. Pretty interesting way of thinking about additive manufacturing, especially for electronics and functional metal parts. Just wow. I only know this is from Singapore, anyone has more information about them? ~~ ♻️ Join the weekly robotics newsletter, and never miss any news →

A 40-year-old patent has finally been brought to life. That's the Y-zipper. A 3D-printed three-sided fastener that transitions any object from flexible to rigid and back again. The robotics application is the one that caught my attention. A quadruped robot that adjusts its leg stiffness depending on terrain, switching between rigid and flexible in real time without additional motors or complex mechanical systems. But this goes way beyond robotics. A wrist cast that loosens during the day and stiffens at night. A tent that pops into shape in 90 seconds instead of six minutes. The idea sat in a patent filing for four decades. It took 3D printing to finally make it real. ~~ ♻️ Join the weekly robotics newsletter, and never miss any news →

It's a 3D printer, and 3D assembly station! 🖨️ The Functgraph developed at Meiji University starts as a regular 3D printer but upgrades itself into a mini factory. It can print parts for its own tools, pick them up, clean them, and put them together, all by itself. Think of it like a robot that can 3D print a spatula, assemble it, and then use it to flip pancakes. 🥞 Instead of just printing objects, the Functgraph can actually perform physical tasks, like folding laundry or slicing vegetables, by using printed and assembled tools. It’s a step toward the idea of a robot that can download "apps" as physical skills, much like your phone downloads software! 👀

OpenAI's thijs predicts robotics will have its own version of the 3D printing craze, with people buying cheap, open-source robot arms and connecting them to agents. "I can see a world quite soon where, similar to when everyone went and bought 3D printers and ran software, everyone's going to buy plastic, cheaper robot arms that you can clip onto a table, put stuff in front of, and plug them into agents." "The price of classic robotics equipment is thousands of dollars at the moment. This arm I'm using here is a Hugging Face SO-100 robot, which is open source, fully 3D printable, and around $200." "People can just pull up Codex and start controlling robots with it right now."

74 seconds to print a 3D Benchy! 🚢 Someone just printed a 3D Benchy in 74 seconds! For context: Benchy is the standard benchmark for 3D printing quality. Getting it done in 74 seconds required pushing every variable to its limit. Pulley and belt systems optimized for minimal slop, machine rigidity improvements to eliminate flex under high acceleration, input shaping to cancel out resonance frequencies that cause ringing artifacts at high speeds. A 3D scanner to analyze print quality objectively. Frequency analysis to identify and cancel specific resonance modes in the frame and motion system.

HyperDreamer: Hyper-Realistic 3D Content Generation and Editing from a Single Image paper page: 3D content creation from a single image is a long-standing yet highly desirable task. Recent advances introduce 2D diffusion priors, yielding reasonable results. However, existing methods are not hyper-realistic enough for post-generation usage, as users cannot view, render and edit the resulting 3D content from a full range. To address these challenges, we introduce HyperDreamer with several key designs and appealing properties: 1) Viewable: 360 degree mesh modeling with high-resolution textures enables the creation of visually compelling 3D models from a full range of observation points. 2) Renderable: Fine-grained semantic segmentation and data-driven priors are incorporated as guidance to learn reasonable albedo, roughness, and specular properties of the materials, enabling semantic-aware arbitrary material estimation. 3) Editable: For a generated model or their own data, users can interactively select any region via a few clicks and efficiently edit the texture with text-based guidance. Extensive experiments demonstrate the effectiveness of HyperDreamer in modeling region-aware materials with high-resolution textures and enabling user-friendly editing. We believe that HyperDreamer holds promise for advancing 3D content creation and finding applications in various domains.

Printing metal made easy! 🖊️ Most metal 3D printing today relies on heat. Lasers or electron beams melt metal powder or wire, fuse it, and let it solidify again. That works, but it’s inefficient: a lot of energy is lost before it ever reaches the material, and even more is wasted as heat dissipates into the surroundings. This work explores a very different idea. Instead of melting metal, it uses high-frequency, low-amplitude mechanical vibrations to temporarily lower a metal’s yield stress and enhance atomic diffusion. Under these conditions, metal can be shaped and joined without full melting. By combining shaping and joining at the same time, the researchers introduce a new additive manufacturing process called Resonance-Assisted Deposition (RAD). Because it avoids melt–solidification, RAD is far more energy-efficient and enables things that are difficult or impossible with conventional methods. Pretty cool method!

Elon Musk reveals the "magic wand number" that shows how cheap anything could be built "If you look at the raw materials in a rocket: aluminum, steel, titanium, copper, specialty alloys, and you ask what's the weight of each constituent element and its raw material value, that sets the asymptotic limit for how low the cost of the vehicle can be, unless you change the materials" "I call it the magic wand number. If you had a pile of these raw materials and could wave a magic wand and rearrange the atoms into the final shape, that would be the lowest possible cost you could make this thing for. And that is almost always a very low number" "So what's actually causing things to be expensive is how you put the atoms into the desired shape"
