This study introduces a novel platform that integrates the principles of drawing lithography with FDM, enabling precise and flexible shape control of extruded filaments. By regulating the non-Newtonian fluid deformation process and the thermodynamics of molten filaments, we successfully fabricate high-quality MN devices with diverse functionalities. This approach achieves needle tip sizes as small as ∼25 µm and variable needle lengths ranging from approximately 600 to 2400 µm by modulating filament drawing speed and distance, facilitating effective skin penetration at varying depths of the stratum corneum. Furthermore, we demonstrate the fabrication of MNs with distinct functionalities, including rapidly separable, bionic serrated, and multilayered designs, supported by mechanical verification and skin penetration assessments. This study innovates the conventional layer-by-layer manufacturing paradigm of FDM, establishing an efficient workflow for high-precision, customisable MN fabrication and broadening the applicability of FDM for biomedical engineering.","PeriodicalId":23756,"journal":{"name":"Virtual and Physical Prototyping","volume":"21 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147886119","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this challenge, we propose an approach leveraging honeycomb sandwich structures with perforated sidewalls to mitigate crack formation. Key structural parameters, including the outer wall thickness (a) and honeycomb cell characteristics such as sidewall height (h), length (l), thickness (t), and perforation diameter (d), are systematically investigated to evaluate their effects on manufacturability and mechanical performance. The characterisations of sintered ceramic parts further elucidate the mechanism of crack formation and validate the approach in this work. Through a comprehensive consideration of fabrication limits, slurry discharge efficiency and mechanical behaviour, the honeycomb sandwich structure with optimised structural parameters exhibits superior mechanical properties after sintering, achieving more than twice the specific modulus and specific strength of the solid references with the same overall dimensions in three-point bending tests. This work provides valuable guidelines for the structural design and fabrication of honeycomb sandwich ceramic structures to achieve large-scale crack-free ceramic parts, demonstrating great promise for lightweight applications.","PeriodicalId":23756,"journal":{"name":"Virtual and Physical Prototyping","volume":"20 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147334022","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two deposition strategies were examined: SS309L followed by Inconel 625, and the reverse order. Microstructural analyses revealed that starting with SS309L led to a shorter elemental transition zone (∼1.5 layers), whereas the reverse sequence produced an extended zone up to 4–5 layers, implying delayed phase stabilisation in the SS309L region. Vickers hardness tests showed that the first case exhibited a stable distribution along the build direction, with interface hardness up to ∼270 HV. In contrast, the reverse order produced a broader high-hardness region exceeding 300 HV in the early SS layers due to delayed ferritic phase formation. Tensile tests revealed that the first case achieved 15% higher ultimate tensile strength (UTS) compared to the second. Furthermore, Digital Image Correlation (DIC) analysis indicated strain was more concentrated near the interface in the first strategy, suggesting stronger interfacial bonding.

The integration of luminescent materials with advanced manufacturing techniques has garnered attention for such applications.

Herein, a novel approach is introduced by optimising the ceramic slurry composition with the addition of LiF as a sintering aid and employing a two-step sintering process. This method significantly enables a threefold increase in elastic modulus, compressive strength, and peak stress compared to previously reported samples. Furthermore, the mechanoluminescent behaviour of these ceramics was demonstrated through experiments that correlate luminescent intensity with applied force, enabling stress visualisation. A stress sensor and a mechanoluminescent shim for railway applications were designed, showcasing the potential of these materials in practical engineering scenarios. This work not only overcomes the limitations of existing methods but also opens new avenues for the application of ZnS/CaZnOS:Mn2+ ceramics in various fields, including structural health monitoring and smart materials.

Extracted natural teeth were collected to prepare standardised bioceramic slurry and evaluate the effect of digital light processing (DLP) process parameters including dispersion dosage solids loading and sintering temperatures. The results demonstrated that 50 vol% solid loading slurry with 2 wt.% dispersant dosage was regarded as the optimum slurry and 1200°C was the optimum sintering temperature.

The results determined that G-scaffold exhibited excellent osteogenic space maintenance and mass transport properties.

Its development has advanced the understanding of curing behaviour, with the Beer–Lambert law commonly used to model the curing process. However, its accuracy in ceramic stereolithography requires further validation. This study examines the response of ceramic slurries to varying irradiance parameters within the Beer–Lambert framework. The fitted results deviate from the model’s predictions when the same slurry is exposed to different irradiation parameters. For slurry S1, the fitted penetration depth values under different parameters (laser power, hatching space, and scanning speed) are 76.2, 113.1, and 85.9 μm, with corresponding critical energy dose values of 14.3, 55.0, and 23.3 mJ/cm2, respectively. For ceramic slurry S2, increasing hatching space raises the energy dose required to reach a 200 μm curing depth from 4.8 to 51.1 mJ/cm2, while increasing scanning speed raises it from 5.7 to 37.2 mJ/cm2. FTIR analysis confirms that higher energy delivery rates reduce polymer conversion. Single-layer tests reveal that a larger hatching space compromises curing uniformity, and faster scanning speeds tend to reduce dimensional stability. These findings highlight the limitations of the Beer–Lambert law and offer insights for process optimisation in ceramic stereolithography.","PeriodicalId":23756,"journal":{"name":"Virtual and Physical Prototyping","volume":"20 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.tandfonline.com/doi/pdf/10.1080/17452759.2025.2544761?needAccess=true","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147893432","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The dissolved MD solute modifies the martensite-to-austenite transformation kinetics, promoting the stabilisation of a predominantly austenitic phase structure.

Recent research highlights additive manufacturing as a pioneering approach for fabricating these complex structures, offering unprecedented control over spatial material distribution. However, it faces significant limitations when producing multi-material objects in the traditional layer-by-layer manner, as the approach requires frequent material switching, making the process prohibitively time-consuming. In this work, we present a two-step multi-material additive manufacturing strategy which achieves the fabrication of multi-material objects by capillary-driving the materials into the pre-printed framework and curing them with external energy sources. This strategy fundamentally eliminates the frequent material switching that occurs in traditional multi-material printing, thereby significantly enhancing the manufacturing efficiency of multi-material objects. Moreover, this strategy accommodates materials previously incompatible with conventional 3D printing. Tailored mechanical properties of multi-material structures can be achieved by adjusting the porosity and position of the framework. By adding stimulus-responsive materials into the multi-material structure, the strategy also enables 4D printing. This strategy opens a new avenue for the development of multi-material additive manufacturing.","PeriodicalId":23756,"journal":{"name":"Virtual and Physical Prototyping","volume":"20 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147334133","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
