Researchers from the Department of Mechanical Engineering at Virginia Tech have introduced a continuous fiber reinforcement (CFR) deposition tool designed for multi-axis 3D printing, significantly enhancing mechanical performance in composite structures. Led by Kieran D. Beaumont, Joseph R. Kubalak, and Christopher B. Williams, and published in Springer Nature Link, the study demonstrates an 820% improvement in maximum load capacity compared to conventional planar short carbon fiber (SCF) 3D printing methods. This tool integrates three key functions: reliable fiber cutting and re-feeding, in situ fiber volume fraction control, and a slender collision volume to support complex multi-axis toolpaths. The newly developed deposition tool addresses critical challenges in CFR additive manufacturing. It is capable of cutting and re-feeding continuous fibers during travel movements, a function required to create complex geometries without material tearing or print failure. In situ control of fiber volume fraction is also achieved by adjusting the polymer extrusion rate. A slender geometry minimizes collisions between the tool and the printed part during multi-axis movements. The researchers designed the tool to co-extrude a thermoplastic polymer matrix with a continuous carbon fiber (CCF) towpreg. This approach allowed reliable fiber re-feeding after each cut and enabled printing with variable fiber content within a single part. The tool’s slender collision volume supports increased range of motion for the robotic arm used in the experiments, allowing alignment of fibers with three-dimensional load paths in complex structures.

Mechanical Testing Confirms Load-Bearing Improvements Mechanical tests evaluated the impact of continuous fiber reinforcement on polylactic acid (PLA) parts. In tensile tests, samples reinforced with continuous carbon fibers achieved a tensile strength of 190.76 MPa and a tensile modulus of 9.98 GPa in the fiber direction. These values compare to 60.31 MPa and 3.01 GPa for neat PLA, and 56.92 MPa and 4.30 GPa for parts containing short carbon fibers. Additional tests assessed intra-layer and inter-layer performance, revealing that the continuous fiber–reinforced material had reduced mechanical properties in these orientations. Compared to neat PLA, intra-layer tensile strength and modulus dropped by 66% and 63%, respectively, and inter-layer strength and modulus decreased by 86% and 60%. Researchers printed curved tensile bar geometries using three methods to evaluate performance in parts with three-dimensional load paths: planar short carbon fiber–reinforced PLA, multi-axis short fiber–reinforced samples, and multi-axis continuous fiber–reinforced composites. The multi-axis short fiber–reinforced parts showed a 41.6% increase in maximum load compared to their planar counterparts. Meanwhile, multi-axis continuous fiber–reinforced parts absorbed loads 8.2 times higher than the planar short fiber–reinforced specimens. Scanning electron microscopy (SEM) images of fracture surfaces revealed fiber pull-out and limited fiber-matrix bonding, particularly in samples with continuous fibers.

To verify the tool’s fiber cutting and re-feeding capability, the researchers printed a 100 × 150 × 3 mm rectangular plaque that required 426 cutting and re-feeding operations across six layers. The deposition tool achieved a 100% success rate, demonstrating reliable cutting and re-feeding without fiber clogging. This reliability is critical for manufacturing complex structures that require frequent travel movements between deposition paths. In situ fiber volume fraction control was validated through printing a rectangular prism sample with varying polymer feed rates, road widths, and layer heights. The fiber volume fractions achieved in different sections of the part were 6.51%, 8.00%, and 9.86%, as measured by cross-sectional microscopy and image analysis. Although lower than some literature reports, the researchers attributed this to the specific combination of tool geometry, polymer-fiber interaction time, and print speed. The tool uses Anisoprint’s CCF towpreg, a pre-impregnated continuous carbon fiber product with a fiber volume fraction of 57% and a diameter of 0.35 mm. 3DXTECH’s black PLA and SCF-PLA filaments were selected to ensure consistent matrix properties and avoid the influence of pigment variations on mechanical testing. The experiments were conducted using an ABB IRB 4600–40/2.55 robotic arm equipped with a tool changer for switching between the CFR-MEX deposition tool and a standard MEX tool with an elongated nozzle for planar prints.

Context Within Existing Research and Future Directions Continuous fiber reinforcement in additive manufacturing has previously demonstrated significant improvements in part performance, with some studies reporting tensile strengths of up to 650 MPa for PLA composites reinforced with continuous carbon fibers. However, traditional three-axis printing methods restrict fiber orientation to planar directions, limiting these gains to within the XY-plane. Multi-axis 3D printing approaches have demonstrated improved load-bearing capacity in short-fiber reinforced parts. For example, multi-axis printed samples have shown failure loads several times higher than planar-printed counterparts in pressure cap and curved geometry applications. Virginia Tech’s tool integrates multiple functionalities that previous tools in literature could not achieve simultaneously. It combines a polymer feeder based on a dual drive extruder, a fiber cutter and re-feeder assembly, and a co-extrusion hotend with adjustable interaction time for fiber-polymer bonding. A needle-like geometry and external pneumatic cooling pipes reduce the risk of collision with the printed part during multi-axis reorientation. Measured collision volume angles were 56.2° for the full tool and 41.6° for the hotend assembly. Load-extension performance graphs for curved tensile bars. Photo via Springer Nature Link. Despite these advances, the researchers identified challenges related to weak bonding between the fiber and the polymer matrix. SEM images showed limited impregnation of the polymer into the fiber towpreg, with the fiber-matrix interface remaining a key area for future work. The study highlights that optimizing fiber tow sizing and improving the fiber-polymer interaction time during printing could enhance inter-layer and intra-layer performance. The results also suggest that advanced toolpath planning algorithms could further leverage the tool’s ability to align fiber deposition along three-dimensional load paths, improving mechanical performance in functional parts. The publication in Springer Nature Link documents the full design, validation experiments, and mechanical characterization of the CFR-MEX tool. The work adds to a growing body of research on multi-axis additive manufacturing, particularly in combining continuous fiber reinforcement with complex geometries.

Researchers from the National University of Singapore (NUS) have developed a 3D printed, self-powered mechanoluminescent (ML) photonic skin designed for communication and safety monitoring in underwater environments. The stretchable device emits light in response to mechanical deformation, requires no external power source, and remains functional under conditions such as high salinity and extreme temperatures. The findings were published in Advanced Materials by Xiaolu Sun, Shaohua Ling, Zhihang Qin, Jinrun Zhou, Quangang Shi, Zhuangjian Liu, and Yu Jun Tan. The research was conducted at NUS and Singapore’s Agency for Science, Technology and Research (A*STAR). Schematic of the 3D printed mechanoluminescent photonic skin showing fabrication steps and light emission under deformation. Image via Sun et al., Advanced Materials. 3D printing stretchable light-emitting skins with auxetic geometry The photonic skin was produced using a 3D printing method called direct-ink-writing (DIW), which involves extruding a specially formulated ink through a fine nozzle to build up complex structures layer by layer. In this case, the ink was made by mixing tiny particles of zinc sulfide doped with copper (ZnS:Cu), a material that glows when stretched, with a flexible silicone rubber. These particles serve as the active ingredient that lights up when the material is deformed, while the silicone acts as a soft, stretchable support structure. To make the device more adaptable to movement and curved surfaces, like human skin or underwater equipment, the researchers printed it using auxetic designs. Auxetic structures have a rare mechanical property known as a negative Poisson’s ratio. Unlike most materials, which become thinner when stretched, auxetic designs expand laterally under tension. This makes them ideal for conforming to curved or irregular surfaces, such as joints, flexible robots, or underwater gear, without wrinkling or detaching. Encapsulating the printed skin in a clear silicone layer further improves performance by distributing mechanical stress evenly. This prevents localized tearing and ensures that the light emission remains bright and uniform, even after 10,000 cycles of stretching and relaxing. In previous stretchable light-emitting devices, uneven stress often led to dimming, flickering, or early material failure. Mechanical and optical performance of encapsulated photonic skin across 10,000 stretch cycles. Image via Sun et al., Advanced Materials. Underwater signaling, robotics, and gas leak detection The team demonstrated multiple applications for the photonic skin. When integrated into wearable gloves, the skin enabled light-based Morse code communication through simple finger gestures. Bending one or more fingers activated the mechanoluminescence, emitting visible flashes that corresponded to messages such as “UP,” “OK,” or “SOS.” The system remained fully functional when submerged in cold water (~7°C), simulating deep-sea conditions. In a separate test, the skin was applied to a gas tank mock-up to monitor for leaks. A pinhole defect was covered with the printed skin and sealed using stretchable tape. When pressurized air escaped through the leak, the localized mechanical force caused a bright cyan glow at the exact leak site, offering a passive, electronics-free alternative to conventional gas sensors. To test performance on soft and mobile platforms, the researchers also mounted the photonic skin onto a robotic fish. As the robot swam through water tanks at different temperatures (24°C, 50°C, and 7°C), the skin continued to light up reliably, demonstrating its resilience and utility for marine robotics.

Toward electronics-free underwater communication While LEDs and optical fibers are widely used in underwater lighting systems, their dependence on rigid form factors and external power makes them unsuitable for dynamic, flexible applications. In contrast, the stretchable ML photonic skin developed by NUS researchers provides a self-powered, adaptable alternative for diver signaling, robotic inspection, and leak detection, potentially transforming the toolkit for underwater communication and safety systems. Future directions include enhanced sensory integration and robotic applications, as the team continues exploring robust photonic systems for extreme environments. Photonic skin integrated into gloves for Morse code signaling and applied to robotic fish and gas tanks for underwater safety monitoring. Image via Sun et al., Advanced Materials. The rise of 3D printed multifunctional materials The development of the photonic skin reflects a broader trend in additive manufacturing toward multifunctional materials, structures that serve more than a structural role. Researchers are increasingly using multimaterial 3D printing to embed sensing, actuation, and signaling functions directly into devices. For example, recent work by SUSTech and City University of Hong Kong on thick-panel origami structures showed how multimaterial printing can enable large, foldable systems with high strength and motion control. These and other advances, including conductive FDM processes and Lithoz’s multimaterial ceramic tools, mark a shift toward printing entire systems. The NUS photonic skin fits squarely within this movement, combining mechanical adaptability, environmental durability, and real-time optical output into a single printable form.

Finding your own path is at the core of gameplay in Pantheon: Rise of the Fallen – players can go anywhere, climb anything, forge new routes, and follow their curiosity to find adventure. It’s not that different from how its creators, Visionary Realms, approaches building this MMORPG – they’re doing it their own way.Transporting players to the fantasy world of Terminus, Pantheon: Rise of the Fallen harkens back to classic MMOs, where accidental discovery wandering through an open world and social interactions with other players are at the heart of the game experience.Creating any multiplayer game is a challenge – but a highly social online game at this scale is an epic quest. We sat down with lead programmer Kyle Olsen about how the team is using Unity to connect players in this MMORPG fantasy world.So what makes Pantheon: Rise of the Fallen unique compared to other MMO games?It’s definitely the social aspect. You have to experience the world and move through it naturally. It can be a bit more of a grind in a way, but it I think connects you more to your character, to the game, and the world instead of just sort of teleporting everywhere and joining LFG systems or just being placed in a dungeon. You learn the land a bit better, you have to navigate and you use your eyes more than just bouncing around like a pinball from objective to objective, following quest markers and stuff. It’s more of a thought game.How are you managing synchronization between the player experience and specific world instances?We have our own network library we built for the socket transport layer called ViNL. That’s the bread and butter for all of the zone communications, between zones and player to zone. SQL server in the back end, kind of standard stuff there. But most of the transports are handled by our own network library.How do you approach asset loading for this giant world?We’ve got a step where we bake our continents out into these tiles, and we’ve got different backends that we can plug into that. We’ve got one that just outputs standard Prefabs, and we’ve got one that outputs subscenes that we were using before Unity 6, and then we’ve got actual full-on Unity scenes that you can load additively, so you can choose how you want to output your content. Before Unity 6, we had moved away from Prefabs and started loading the DOTS subscenes and using that, built on BRG.We also have an output that can render directly to our own custom batch render group as well, just using scriptable objects and managing our own data. So we’ve been able to experiment and test out the different ones, and see what yields the best client performance. Prior to Unity 6, we were outputting and rendering the entire continent with subscenes, but with Unity 6 we actually switched back to using Prefabs with Instantiate Async and Addressables to manage everything.We’re using the Resident Drawer and GPU occlusion culling, which ended up yielding even better performance than subscenes and our own batch render group – I’m assuming because GPU occlusion culling just isn’t supported by some of the other render paths at the moment. So we’ve bounced around quite a bit, and we landed on Addressables for managing all the memory and asset loading, and regular Instantiate Prefabs with the GPU Resident Drawer seems to be the best client-side performance at the moment.Did you upgrade to Unity 6 to take advantage of the GPU Resident Drawer, specifically?Actually, I really wanted it for the occlusion culling. I wasn’t aware that only certain render paths made use of the occlusion culling, so we were attempting to use it with the same subscene rendering that we were using prior to Unity 6 and realizing nothing’s actually being culled. So we opted to switch back to the Prefab output to see what that looked like with the Resident Drawer, and occlusion culling and FPS went up.We had some issues initially, because Instantiate Async wasn’t in before Unity 6, so we had some stalls when we would instantiate our tiles. There were quite a few things being instantiated, but switching that over to Instantiate Async after we fixed a couple of bugs we got rid of the stall on load and the overall frame rate was higher after load, so it was just a win-win.Were there any really remarkable productivity gains that came with the switch to Unity 6?Everything I've talked about so far was client-facing, so our players experienced those wins. For the developer side of things, the stability and performance of the Editor went up quite a bit. The Editor stability in Unity 6 has gone up pretty substantially – it’s very rare to actually crash now. That alone has been, at least for the coding side, a huge win. It feels more stable in its entirety for sure.How do you handle making changes and updates without breaking everything?We build with Addressables using the labels very heavily, and we do the Addressable packaging by labels. So if we edit a specific zone or an asset in a zone, or like a VFX that’s associated with a spell or something like that, only those bundles that touch that label get updated at all.And then, our own content delivery system, we have the game available on Steam and our own patcher, and those both handle the delta changes, where we’re just delivering small updates through those Addressable bundles. The netcode requires the same version to be connected in the first place, so the network library side of that is automatically handled in the handshake process.What guidance would you give someone who’s trying to tackle an MMO game or another ambitious multiplayer project?You kind of start small, I guess. It's a step-by-step process. If you’re a small team, you You start small. It's a step-by-step process. If you’re a small team, you can’t bite off too much. It’d be completely overwhelming – but that holds true with any larger-scale game, not just an MMO. Probably technology selection – making smart choices upfront and sticking to them. It’s going to be a lot of middleware and backend tech that you’re going to have to wrangle and get working well together, and swapping to the newest cool thing all the time is not going to bode well.What’s the most exciting technical achievement for your team with this game?I think that there aren’t many open world MMOs, period, that have been pulled off in Unity. We don’t have a huge team, and we're making a game that is genuinely massive, so we have to focus on little isolated areas, develop them as best we can, and then move on and get feedback.The whole package together is fairly new grounds – when there is an MMO, it needs to feel like an MMO in spirit, with lots of people all around, doing their own thing. And we’ve pulled that off – I think better than pretty much any Unity MMO ever has. I think we can pat ourselves on the back for that.Get more insights from developers on Unity’s Resources page and here on the blog. Check out Pantheon: Rise of the Fallen in Early Access on Steam.

Researchers at the University of Texas at Austin have developed a novel resin system for multicolor digital light processing (DLP) 3D printing that enables rapid fabrication of freestanding and non-assembly structures using dissolvable supports. The work, led by Zachariah A. Page and published in ACS Central Science, combines UV- and visible-light-responsive chemistries to produce materials with distinct solubility profiles, significantly streamlining post-processing. Current DLP workflows are often limited by the need for manually removed support structures, especially when fabricating components with overhangs or internal joints. These limitations constrain automation and increase production time and cost. To overcome this, the team designed wavelength-selective photopolymer resins that form either an insoluble thermoset or a readily dissolvable thermoplastic, depending on the light color used during printing. In practical terms, this allows supports to be printed in one material and rapidly dissolved using ethyl acetate, an environmentally friendly solvent, without affecting the primary structure. The supports dissolve in under 10 minutes at room temperature, eliminating the need for time-consuming sanding or cutting. Illustration comparing traditional DLP 3D printing with manual support removal (A) and the new multicolor DLP process with dissolvable supports (B). Image via University of Texas at Austin. The research was supported by the U.S. Army Research Office, the National Science Foundation, and the Robert A. Welch Foundation. The authors also acknowledge collaboration with MonoPrinter and Lawrence Livermore National Laboratory. High-resolution multimaterial printing The research showcases how multicolor DLP can serve as a precise multimaterial platform, achieving sub-100 μm feature resolution with layer heights as low as 50 μm. By tuning the photoinitiator and photoacid systems to respond selectively to ultraviolet (365 nm), violet (405 nm), or blue (460 nm) light, the team spatially controlled polymer network formation in a single vat. This enabled the production of complex, freestanding structures such as chainmail, hooks with unsupported overhangs, and fully enclosed joints, which traditionally require extensive post-processing or multi-step assembly. The supports, printed in a visible-light-cured thermoplastic, demonstrated sufficient mechanical integrity during the build, with tensile moduli around 160–200 MPa. Yet, upon immersion in ethyl acetate, they dissolved within 10 minutes, leaving the UV-cured thermoset structure intact. Surface profilometry confirmed that including a single interface layer of the dissolvable material between the support and the final object significantly improved surface finish, lowering roughness to under 5 μm without polishing. Computed tomography scans validated geometric fidelity, with dimensional deviations from CAD files as low as 126 μm, reinforcing the method’s capability for high-precision, solvent-cleared multimaterial printing.

Towards scalable automation This work marks a significant step toward automated vat photopolymerization workflows. By removing manual support removal and achieving clean surface finishes with minimal roughness, the method could benefit applications in medical devices, robotics, and consumer products. The authors suggest that future work may involve refining resin formulations to enhance performance and print speed, possibly incorporating new reactive diluents and opaquing agents for improved resolution. Examples of printed freestanding and non-assembly structures, including a retainer, hook with overhangs, interlocked chains, and revolute joints, before and after dissolvable support removal. Image via University of Texas at Austin. Dissolvable materials as post-processing solutions Dissolvable supports have been a focal point in additive manufacturing, particularly for enhancing the efficiency of post-processing. In Fused Deposition Modeling (FDM), materials like Stratasys’ SR-30 have been effectively removed using specialized cleaning agents such as Oryx Additive‘s SRC1, which dissolves supports at twice the speed of traditional solutions. For resin-based printing, systems like Xioneer‘s Vortex EZ employ heat and fluid agitation to streamline the removal of soluble supports . In metal additive manufacturing, innovations have led to the development of chemical processes that selectively dissolve support structures without compromising the integrity of the main part . These advancements underscore the industry’s commitment to reducing manual intervention and improving the overall efficiency of 3D printing workflows. Read the full article in ACS Publications.
