  • New tech 3D-prints durable zirconia dental crowns in just hours

    Researchers at the University of Texas at Dallas have developed a groundbreaking 3D-printing technology that enables the production of permanent zirconia dental crowns in just a few hours, potentially allowing patients to receive same-day restorations. Zirconia is considered the gold standard for durable dental work, but traditional manufacturing methods, such as milling, limit design complexity and risk micro-cracking. Existing 3D-printed crowns use ceramic resins that lack zirconia’s strength. The key innovation lies in drastically reducing the debinding process—from 20-100 hours to under 30 minutes—by using porous graphite felt, enhanced heat transfer, and a vacuum system that safely removes gas during resin burnout, preventing cracks and fractures. This advancement not only accelerates the production timeline but also offers stronger, more customizable dental restorations compared to resin alternatives and milled zirconia. The technology promises to lower waste and costs while improving patient experience by enabling dentists to provide permanent crowns, bridges, and veneers chair-side in a

  • New software helps build 3D objects with smooth material transitions

    OpenVCAD is a new open-source software tool developed at the University of Colorado Boulder that revolutionizes multi-material 3D design by enabling engineers to create objects with smooth material gradients through code-driven precision. Unlike traditional CAD tools that define only an object’s outer boundaries and assume a single interior material, OpenVCAD allows users to assign complex mathematical functions to represent spatially varying materials within a 3D object. This capability simplifies the design of gradient objects—such as shoe soles transitioning from firm to soft—by letting users update designs through small code changes rather than redrawing entire models. Created in the Matter Assembly Computation Lab under Assistant Professor Robert MacCurdy and developed by PhD student Charles Wade, OpenVCAD supports multi-material printing with up to five materials simultaneously and has demonstrated versatility across various 3D printers. Its applications extend beyond academia to fields like medical modeling, soft robotics, and structural engineering, where it can help create lifelike anatomical models, flexible robotic actuators, and

  • Swiss scientists' new 3D printing method delivers ultra-strong materials

    Researchers at EPFL have developed a novel 3D printing method that creates ultra-strong metal and ceramic materials by growing them inside a water-based hydrogel scaffold. Unlike traditional approaches that harden resin pre-infused with metal precursors using light, this technique first prints a simple hydrogel structure, which is then infused repeatedly with metal salts and chemically converted into metal-containing nanoparticles. This post-printing material infusion allows for high metal concentrations and results in dense, intricate architectures with significantly improved mechanical properties. The new materials can withstand pressures up to 20 times greater than those produced by previous methods while exhibiting only about 20% shrinkage compared to the typical 60-90%. The team demonstrated the method’s versatility by fabricating complex gyroid lattice structures from iron, silver, and copper, which are strong yet lightweight. This approach is promising for advanced applications requiring complex 3D architectures that combine strength and low weight, such as sensors, biomedical devices, and energy conversion or storage technologies.

  • MIT's high strength aluminum alloy can withstand high temperature

    Researchers at MIT have developed a novel printable aluminum alloy that is reportedly five times stronger than traditionally manufactured aluminum and can withstand high temperatures. Using a machine learning (ML)-based approach combined with simulations, the team evaluated only 40 possible material compositions—significantly fewer than the over one million combinations typically required—to identify an optimal mix of aluminum and other elements. This alloy exhibits a high volume fraction of small precipitates, which contribute to its enhanced strength, surpassing previous benchmarks including the wrought Al 7075 alloy. The new alloy, produced via 3D printing rather than conventional casting, benefits from rapid solidification that prevents precipitate growth, resulting in superior mechanical properties. After aging at 400 °C for eight hours, the alloy achieves a tensile strength of 395 MPa at room temperature, about 50% stronger than the best-known printable aluminum alloys. The researchers envision applications in lightweight, temperature-resistant components such as jet engine fan blades—traditionally made from heavier and more expensive

  • Korean researchers create bone-healing gun, offers faster treatment

    Korean researchers at Sungkyunkwan University have developed a handheld “bone-healing gun,” a 3D-printing device that extrudes biodegradable polymer scaffolds directly onto fractured bones to accelerate healing. Unlike traditional metal grafts and titanium implants, which are costly and difficult to customize, this device uses a biocompatible filament made from a blend of polycaprolactone and hydroxyapatite. This material melts at a safe 60 °C, allowing it to bond securely to bone tissue without damaging surrounding areas, while providing strength comparable to natural bone and gradually degrading as new bone grows. Early animal trials on rabbits with femur fractures showed that the bone-healing gun significantly sped up recovery compared to standard bone cement. However, the slow degradation rate of the scaffold material limited full fracture restoration, indicating the need for further improvements before human trials. The researchers aim to enhance the material’s biodegradation speed and incorporate antibiotics to release infection-fighting drugs during healing. Additional challenges include ensuring

  • Argonne studies 3D-printed steels for next-gen nuclear reactors

    Researchers at the US Department of Energy’s Argonne National Laboratory have conducted studies on 3D-printed stainless steels to support the development of next-generation nuclear reactor components. Using laser powder bed fusion (LPBF), an additive manufacturing technique, they produced samples of two key alloys: 316H, a conventional stainless steel used in reactors, and Alloy 709 (A709), a newer alloy designed for advanced nuclear applications. The LPBF process creates unique microstructural features due to rapid heating and cooling, including numerous dislocations that can both strengthen the steel and increase its susceptibility to fracture. Heat treatments are applied to relieve stress by allowing atomic rearrangement, but some dislocations may be retained to enhance performance. The studies revealed significant differences between 3D-printed and conventionally wrought steels, particularly in how the printed materials respond to heat treatments. For 316H, experiments using advanced microscopy and in situ X-ray diffraction showed that nano oxides—common defects in 3D-printed

  • 3D printable bio-glass scaffold shows promise as bone replacement

    Researchers in China have developed a novel 3D printable bio-active glass scaffold that shows promise as a bone replacement material. Unlike traditional glass, which is brittle and difficult to shape safely for medical use, this new bio-glass combines silica particles with calcium and phosphate ions to form a printable gel. This gel can be hardened at a relatively low temperature (1,300°F), avoiding the toxic plasticizers and extreme heat (above 2,000°F) typically required in glass 3D printing. In animal tests involving rabbit skull repair, the bio-glass scaffold supported sustained bone cell growth over eight weeks, outperforming plain silica glass and nearly matching a leading commercial dental bone substitute in durability. The key innovation lies in the “green” inorganic 3D printing strategy, which uses self-healing colloidal gels made from silica-based nanospheres that attract each other electrostatically. This method eliminates the need for organic additives, reduces costs, preserves bioactivity, and enhances printability and shape

  • Researchers Create 3D-Printed Artificial Skin That Allows Blood Circulation

    Swedish researchers have developed innovative 3D bioprinting techniques to create thick, vascularized artificial skin that could significantly improve treatment for severe burns and trauma. Traditional skin grafts transplant only the epidermis and fail to regenerate the dermis—the deeper skin layer containing blood vessels and nerves—resulting in scarring and loss of full skin function. The new methods aim to overcome this by producing skin that includes living cells and a network of blood vessels, essential for delivering oxygen and nutrients to sustain tissue viability. The team led by Johan Junker at Linköping University created a bio-ink called “μInk,” which embeds fibroblasts (cells that generate dermal components like collagen) within a gel matrix, allowing 3D printing of dense, cell-rich skin structures. In mouse transplantation experiments, these constructs supported cell growth, collagen secretion, and new blood vessel formation, indicating potential for long-term tissue integration. Complementing this, the researchers developed the REFRESH technology, which uses

  • New 3D print method reduces plastic use without losing strength

    MIT researchers from CSAIL and the Hasso Plattner Institute have developed SustainaPrint, a hybrid 3D printing system that significantly reduces plastic waste without compromising structural strength. The method uses simulations to identify stress-prone zones in a 3D model and selectively reinforces these areas with high-performance plastics, while printing the rest of the object with biodegradable or recycled filament. This targeted reinforcement approach cuts down plastic use and maintains durability, addressing the common trade-off between eco-friendliness and strength in 3D printing materials. In tests using Polymaker’s eco-friendly PolyTerra PLA and Ultimaker’s stronger PLA, SustainaPrint required only 20% reinforcement to regain up to 70% of the strength of fully reinforced prints. In some cases, the hybrid prints matched or even outperformed fully strong prints, demonstrating that strategic material mixing can enhance performance depending on geometry and load conditions. The system includes an open-source software interface for uploading models and running stress simulations, along with

  • 3D-printed scaffolds guide stem cells to repair spinal cord injury

    A research team at the University of Minnesota Twin Cities has developed a novel approach to spinal cord injury repair by combining 3D printing, stem cell biology, and regenerative medicine. They created a 3D-printed organoid scaffold containing microscopic channels filled with spinal neural progenitor cells (sNPCs) derived from human adult stem cells. These channels guide the growth of the stem cells, promoting the formation of new nerve fibers that can bypass damaged spinal cord areas. When implanted into rats with completely severed spinal cords, the scaffolds supported the development of neurons that extended nerve fibers in both directions, integrating with existing spinal tissue and leading to significant functional recovery. The study demonstrates that the scaffold not only enhances cell survival but also enables reconnection across severe spinal injuries, marking a promising advance in regenerative medicine for paralysis. The researchers plan to scale up and refine the technology for clinical trials, aiming to eventually restore mobility and independence in people with spinal cord injuries.

  • Students build aerospace 3D printer that fuses two metals at once

    A team of Swiss bachelor students at ETH Zurich has developed an innovative 3D metal printer, named RAPTURE, that significantly advances aerospace manufacturing by enabling high-speed, multi-material printing. Unlike traditional 3D printers that operate in a stop-start manner, this prototype uses a rotating laser powder bed fusion (LPBF) system to continuously deposit and fuse metal powders. This design allows the simultaneous fusion of two different metals—such as a copper core with a nickel-alloy exterior—in a single seamless step, which is particularly suited for producing complex aerospace components like rocket nozzles and turbine parts with large diameters and thin walls. The rotating platform reduces production time by over two-thirds compared to conventional methods. The RAPTURE machine also incorporates a novel gas flow system that directs inert gas across the fusion zone to prevent oxidation and continuously removes by-products like soot and spatter, resulting in cleaner builds and higher part quality.

  • 3D-printed auxetic sensors promise leap in wearable electronics

    A research team from Seoul National University of Science and Technology, led by Mingyu Kang and Dr. Soonjae Pyo, has developed a novel 3D-printed tactile sensor platform based on auxetic mechanical metamaterials (AMMs). These materials exhibit a negative Poisson’s ratio, meaning they contract inward under compression, which concentrates strain and enhances sensitivity. Using digital light processing (DLP)-based 3D printing, the team fabricated cubic lattice structures with spherical voids that improve sensor performance by increasing sensitivity, maintaining stability, and minimizing crosstalk. The sensors operate in capacitive and piezoresistive modes, with the latter utilizing a carbon nanotube coating to detect resistance changes under load. The researchers demonstrated the technology’s potential through applications such as tactile arrays for spatial pressure mapping and wearable smart insoles capable of monitoring gait patterns and detecting pronation types.

  • University of Waterloo researchers develop robots to directly treat kidney stones - The Robot Report

    Researchers at the University of Waterloo, led by Dr. Veronika Magdanz, have developed a novel robotic technology aimed at directly treating kidney stones by dissolving them within the urinary tract. Kidney stones affect about 12% of people and often require prolonged drug treatments or surgeries, which can be painful and burdensome. The new minimally invasive approach uses thin, flexible, magnetically controlled strips about 1 cm long, embedded with the enzyme urease. These strips are maneuvered near uric acid kidney stones using a robotic arm guided by doctors, where the enzyme reduces urine acidity, accelerating stone dissolution so they can pass naturally within days. The technology was tested in life-size, 3D-printed urinary tract models and shows promise especially for patients who frequently develop stones or cannot tolerate oral medications or surgery due to risks like chronic infections. The system combines a motorized magnet on a robotic arm with real-time ultrasound imaging to precisely position the enzyme-loaded robots near the stones. Next steps for the

  • Robot crab reveals how male crabs compete to attract female mates

    A study conducted by researchers at the University of Exeter’s Centre for Research in Animal Behaviour (CRAB) used a robotic crab named Wavy Dave to investigate how male fiddler crabs compete for female mates. Male fiddler crabs attract females by waving their one oversized claw outside their burrows, a key sexual signal. The robotic crab, equipped with a 3D-printed body and waving claw, was placed near real male crabs in southern Portugal to observe their reactions to a mechanical rival. The study found that male crabs increased their claw-waving duration and were less likely to retreat when the robot waved, especially when it had a smaller claw, indicating that males adjust their signaling behavior dynamically in response to competition. The research also revealed that male crabs were less likely to challenge rivals with larger claws, likely due to fear of losing or injury. Some males even physically attacked the robotic crab, with one crab pulling off Wavy Dave’s claw and ending the trial. These behaviors suggest

  • MIT vision system teaches robots to understand their bodies

    MIT researchers at CSAIL have developed a novel robotic control system called Neural Jacobian Fields (NJF) that enables robots to learn how their bodies move in response to motor commands purely through visual observation, without relying on embedded sensors or hand-coded models. Using a single camera and random exploratory movements, NJF allows robots—ranging from soft robotic hands to rigid arms and rotating platforms—to autonomously build an internal model of their 3D geometry and control sensitivities. This approach mimics how humans learn to control their limbs by observing and adapting to their own movements, shifting robotics from traditional programming toward teaching robots through experience. NJF’s key innovation lies in decoupling robot control from hardware constraints, enabling designers to create soft, deformable, or irregularly shaped robots without embedding sensors or modifying structures for easier modeling. By leveraging a neural network inspired by neural radiance fields (NeRF), NJF reconstructs the robot’s shape and its response to control inputs solely from visual data. This

  • ‘Shocking’ 3D resin may build soft robots with plastic-like strength

    Researchers at the University of Texas at Austin have developed an innovative 3D printing technique that uses a custom liquid resin and a dual-light system to create objects combining both soft, rubber-like flexibility and hard, plastic-like strength within a single print. Inspired by natural structures such as human bones and cartilage, this method employs violet light to produce flexible material and ultraviolet light to harden the resin, enabling seamless transitions between soft and rigid zones without weak interfaces. This breakthrough addresses common issues in multi-material printing where different materials often fail at their boundaries. Demonstrations of the technology included printing a functional knee joint with soft ligaments and hard bones that moved smoothly together, as well as a stretchable electronic device with flexible and stiff areas to protect circuitry. The researchers were surprised by the immediate success and the stark contrast in mechanical properties achieved. An adjacent study published in ACS Central Science further highlights the potential of light-driven resin chemistry to advance additive manufacturing, offering faster production, higher resolution, and new design freedoms.

  • MIT's new AI outsmarts human design to help robots jump 41% higher

    MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) has developed a new generative AI approach that designs robots capable of jumping 41% higher than those created by human engineers. Using diffusion-based generative models, researchers allowed the AI to modify specific parts of a 3D robot model, resulting in curved linkages resembling thick drumsticks rather than the straight, rectangular parts of traditional designs. This unique shape enabled the robot to store more energy before jumping, improving performance without compromising structural integrity. The AI-assisted robot also demonstrated an 84% reduction in falls compared to the baseline model, highlighting enhanced stability and landing safety. The process involved iterative refinement, with the AI generating multiple design drafts that were scaled and fabricated using 3D-printable polylactic acid material. Researchers believe that future iterations using lighter materials could achieve even higher jumps. Beyond jumping robots, the team envisions applying diffusion models to optimize how parts connect and to design robots with more complex capabilities, such as directional control and

  • Scientists 3D-print thermal insulation fibres from wheat straw

    Researchers led by Dr. Chi Zhou at the University at Buffalo have developed a sustainable thermal insulation material by 3D-printing fibers derived from wheat straw, an agricultural byproduct typically burned after harvest. Wheat straw’s natural fibrous and porous structure provides effective thermal insulation, high mechanical strength, and enhanced flame retardancy compared to other organic materials. The process involves pulping wheat straw into a slurry, drying it into a thick ink, and cross-linking the fibers with an organic binder to ensure material integrity before 3D printing. This innovation offers a renewable, biodegradable alternative to conventional insulation materials like glass and rock wool, which rely heavily on fossil fuels and contribute to greenhouse gas emissions. To address the slow printing speed of early methods, Zhou’s team redesigned the 3D printer with a slot-die nozzle and multiple nozzles for faster, more uniform material deposition, making the process scalable for industrial production. Using wheat straw not only reduces environmental impact by lowering emissions and decreasing agricultural waste but

  • Live bacteria-infused sustainable building material traps CO2 from air

    Researchers at ETH Zurich have developed an innovative, sustainable building material infused with live cyanobacteria that actively captures atmospheric carbon dioxide through photosynthesis and biocementation. This 3D-printed hydrogel-based material houses photosynthetic bacteria within a polymer network designed to optimize light, CO2, water, and nutrient flow, enabling the bacteria to remain productive for over a year. The material sequesters CO2 both biologically and by forming stable mineral carbonates, which strengthen the initially soft gel into a robust, hardened structure over time. Laboratory tests demonstrated that the material can bind approximately 26 milligrams of CO2 per gram, outperforming typical biological methods and rivaling chemical mineralization in recycled concrete. The technology has moved beyond the lab, with large-scale installations such as the "Picoplanktonics" exhibit at the Architecture Biennale in Venice, featuring three-meter-high structures capable of capturing up to 18 kilograms of CO2 annually—comparable to a mature pine tree.

  • US scientists develop real-time defect detection for 3D metal printing

    Scientists from Argonne National Laboratory and the University of Virginia have developed a novel method to detect defects, specifically keyhole pores, in metal parts produced by 3D printing using laser powder bed fusion. Keyhole pores are tiny internal cavities formed when excessive laser energy creates deep, narrow holes that trap gas, compromising the structural integrity and performance of critical components such as aerospace parts and medical implants. The new approach combines thermal imaging, X-ray imaging, and machine learning to predict pore formation in real-time by correlating surface heat patterns with internal defects captured via powerful X-rays. This method leverages existing thermal cameras already installed on many 3D printers, enabling instant detection of internal flaws without the need for continuous expensive X-ray imaging. The AI model, trained on synchronized thermal and X-ray data, can identify pore formation within milliseconds, allowing for immediate intervention. Researchers envision integrating this technology with automatic correction systems that adjust printing parameters or reprint layers on the fly, thereby improving reliability, reducing waste, and enhancing safety in manufacturing mission-critical metal parts. Future work aims to expand defect detection capabilities and develop repair mechanisms during the additive manufacturing process.
