Data from: Osmia3DNest – novel designed 3D printed artificial nest for solitary cavity-nesting bees
<p>The availability and appropriateness of nesting sites significantly influence the reproductive success and overall welfare of wild bees. Human-induced factors contribute to the destruction of natural nesting habitats. To address these limitations, innovative solutions such as the development of artificial nests, as indicated in recent studies, offer alternative nest sites to support wild bee populations. We designed the Osmia3DNest, a 3D printed standardized nest tube for solitary cavity-nesting bees, aiming to provide a safety for the environment life-long, time-saving, and biodegradable product that anyone can print. We proudly present the two Osmia3DNest models for mason bees – closed and open – using PLA filament. We demonstrate the effectiveness of Osmia3DNest on mason bee reproduction parameters compared with traditional reed nests. Osmia3DNest can be an alternative to the other artificial nests, which people can customize for their necessity depending on their place of living (rural or urban area), and they can also be washed and reused several times and then decomposed. Osmia3DNest holds potential for wildlife biologists, management of pollinators, and educational outreach, offering adaptability for different bee species and experimental needs.</p>

Studies on 3D printing of Na3Zr2Si2PO12 ceramic solid electrolyte through Fused Filament Fabrication
<p><span>Solid-state batteries are considered being the next step in battery technology to achieve higher energy densities and potentially safer batteries. As there is no organic liquid, the risk of flammability is drastically reduced. Nevertheless, there are numerous challenges associated with the realization of all-solid-state batteries, such as improving slow kinetics, contact interface issues between battery components and cell integration among others. 3D printing holds the potential to address these issues as it <span> </span>allows to improve kinetics by structuring the battery components and the possibility of a customized cell integration. A structured surface of the electrolyte can in principle also enhance interface effects with the metal electrode. To contribute in this regard, composite filaments with Na<sub>3</sub>Zr<sub>2</sub>Si<sub>2</sub>PO<sub>12</sub> were fabricated and 3D printed. Subsequent sintering of the printed parts after removal of the polymer components led to the required densification of the fully ceramic electrolyte. The parts were microstructurally and electrochemically characterized and showed a reasonable performance with an ionic conductivity of (3.02 ± 0.14) · 10<sup>-4</sup> S·cm<sup>-1</sup> at 20 °C. Critical current density testing revealed stable cycling up to 200 mA·cm<sup>-2</sup>, with cell failure occurring at a current density of 750 mA·cm<sup>-2</sup>, demonstrating the application potential of 3D printed full ceramic solid electrolytes. </span></p>

3D printing lifts the lid on black box instruments
<p>Within analytical chemistry, chemical instruments involve numerous interconnected parts working cohesively towards a specific functionality. However, these highly complex mechanisms cannot be fully depicted with a 2-dimensional textbook model or image, leading to confusion or misconceptions during the learning process. To address this comprehension gap, an array of chemical instrument components have been designed and fabricated with 3D printing to create a hands-on learning experience. The models developed were created in interlocking parts to allow disassembly and investigation of the inner workings of each instrument component. This work produced a series of teaching aids and dynamic models for common instruments including a quadrupole, quadrupole-ion-trap, orbitrap, FTICR mass spectrometer; a GC injection port, FID, and ECD detectors; an HPLC injector; an ICP torch and nebulizer; a Michaelson interferometer; a basic monochromator; and a shatterbox sample preparation device. These models were designed to be interactive and hand-held 1:1 scale models of commercial instrument components. Using these models, students' learning may be expanded from 2 to 3 dimensions; providing hands-on experience with modern laboratory instrumentation impossible with commercial instrumentation. Models were used in a small Analytical Chemistry lecture (<em>n</em> = 8) which demonstrated positive student reception, especially for models with kinematic relations to instrument functionality.</p>

Setup of a 3D printed wind tunnel: application for calibrating bi-directional velocity probes used in Fire Engineering Applications
<p>The research presented here focuses on the development of a 3D printed wind tunnel and the relevant equipment to be used for calibrating bi-directional velocity probes (BDVP). BDVP are equipment to be used for measuring velocity flow by determining the pressure difference of hot gases generated during fires. The manufactured probes require calibration to determine the calibration factor to achieve precise measurement. The calibration is usually performed in wind tunnels which can be difficult to access due to costs, complexity and the various pieces of equipment required. The aim of the current study is to develop and assemble an inexpensive and easy-to-build bench-scale wind tunnel, with a data-logging system and fan control functionalities for fast and effective calibration of BDVP. A 3D printer with a PET-G filament is used, able to produce parts for the wind tunnel system which are durable and easy to handle and assemble. The system additionally includes an Arduino-based measuring unit with a hot-wire anemometer and temperature correction: Rev. P. This takes precise measurements; continuously logging data on a computer through a USB interface and capable of saving data on an SD card. This design provides users with parameters of velocity flow up to 4 m/s with standard deviation of 1.2 % and turbulence intensity of 1 %. The main advantages of this wind tunnel are its simplicity to build and portability.</p> <p>The dataset contains design files for 3D printing of the wind tunnel, BOM and wiring of electronic components.</p> <p>The project is prototype under development and authors are not responsible for any damages or injuries caused by inappropriate construction or operation.

Rebar-Free 3D Printing of Transportation Infrastructure
<p>This study investigates the fresh and hardened-state properties of printing mixtures including different dosages of steel fibers, especially at higher dosages which have not been investigated before. This study also considers the effects of other parameters such as sand-to-powder ratio and the limestone content on the properties of steel fiber reinforced printing materials, to reduce the Portland cement content which has a high carbon footprint. The obtained experimental results revealed that high-performance materials incorporating up to 2.5% steel fibers (by volume) can be successfully 3D printed. The mechanical properties of the reinforced mixtures improved significantly at high fiber dosages (2% and 2.5% vol.). By incorporating 2% and 2.5% vol. of steel fibers, the compressive strength results showed up to 109% and 50% increase in strength compared to the control mixture, at 7 days and 28 days, respectively. In addition, significant improvement in the flexural strength, tensile strength and toughness of printing materials were achieved at high dosages of steel fiber inclusion. The obtained results also reveal that the orientation and alignment degree of steel fibers in the composite is affected by different parameters such as the binder content and nozzle design. In addition, an electromechanical module was successfully designed, developed, and implemented with an existing printing system to enable a semi-automated screw insertion process in parallel with the layer deposition process. This highlights the feasibility of a fully automated layer deposition and reinforcement process for future real-life construction projects. </p>

Evaluation of Fresh and Hardened Properties of 3D-Printed Engineered Cementitious Composites (ECC) Designed for Sustainable and Resilient Infrastructure Systems
<p>3D concrete printing is a cutting-edge construction technique that has the potential to revolutionize the construction industry due to cost-saving in terms of labor and formwork costs, efficiency in construction, lower safety-related risks, and a higher degree of automation. However, several issues still make its adoption relatively slower on a large scale. Engineered cementitious composites (ECC), a class of ultra-high-strength concrete, can be a potential solution to some problems, such as reinforcement and durability. The preliminary phase of a Tran SET project focused on the design of 3D printable ECC, considering the concrete mix design proportions and their potential effects on fresh and hardened properties to achieve an optimized printable ECC mix. The type and content of various concrete ingredients such as cement, admixtures, aggregates, and fibers have considerable influence on the several properties in the fresh and hardened state. The replacement levels for cement were 0%, 50%, and 75% for mineral admixture, 10% for silica fume, and 0.4% for nano-clay by cement mass. Locally available fine aggregates were also used at 25% and 40% by mass of binder. In addition, the influence of fiber types and contents was also investigated. Two types of fibers, polyethylene (PE) and polyvinyl alcohol (PVA) fibers, were used at different levels, such as 0%, 1%, 1.5%, and 2% of the total volume of the mix. Moreover, four mixes, including FA50-MC, FA40SF10-MC, S50-MC, and FA40MK10-MC, were evaluated in terms of mechanical performance (flexural strength and direct tensile strength). The flowability of the ECC mixes was reduced with the incorporation of slag, metakaolin, higher aggregate content, and PE fibers. The 2% of both PVA and PE fibers had a reduction in compressive strength as compared to the low fiber content. Moreover, the PE-ECC exhibited superior tensile ductility as compared to the PVA-ECC due to the more fiber bridging by the PE fibers at the crack interface.</p>
