1. Preparation of Biomimetic Shells from Biomass Based on Selective Laser Sintering Technology.
PMID:日期:2026-02-18Shells, a type of food waste, present a notable challenge in achieving high-value applications in the environmental sector owing to their complex compositions, limited recycling applications, and the environmental impact of improper disposal. This study conducts a comparative analysis of the mechanical properties of five types of natural shells: veined red snail, mussel, oyster, scallop, and green willow clam. Shell powders and polylactic acid (PLA) were used as the inorganic and organic components of shells, respectively. The laser sintering mechanism for forming these components was explored, resulting in the fabrication of five biomimetic shells. Results showed that the flexural strength decreased in the order of veined red snail > mussel > scallop > green willow clam > oyster. The flexural strength values of laser-sintered specimens made from five shell powder/PLA composites corresponded closely to those of their respective shells, with values of 8.6, 8.1, 7.6, 6.9, and 6.1 MPa. These values exceeded those of pure PLA specimens. Furthermore, the compressive load capacity of 3D-printed biomimetic veined red snail parts, 3D-printed biomimetic mussel parts, 3D-printed oyster parts, 3D-printed biomimetic scallop parts, and 3D-printed biomimetic green willow clam parts reached 76.69%, 19.10%, 5.57 times, 26.66%, and 70.46%, of the load capacities of the natural shell counterparts, respectively.

2. Experimental and Numerical Analysis of Titanium 3D Body-Centered Cubic Lattice Structure Additively Manufactured Using Selective Laser Melting.
PMID:日期:2026-02-18This study investigates the mechanical responses in three-point bending and compression of body-centered cubic (BCC) for specific aerospace applications to achieve lightweight and improved mechanical properties. The mechanical characteristics of functionally graded BCC lattice structures were explored, resulting in enhanced mechanical features compared with uniform-graded BCC lattice structures. Due to the gradient lattice structure, the average bending load significantly increased to 62.5%. It was found that the BCC lattice structure only exhibits a dual failure model comprising buckling and fracture, compared with other lattice structures that often offer sole buckling or fracture failure. The buckling of the struts starts from the bottom and ends with a fracture. BCC lattice sandwiches provide an opportunity to balance strength and weight ratio effectively. The experimental findings showed close agreement with finite element results. Numerical modeling illustrates the stress-strain and force-deformation curves, and the failure mechanism is the strut buckling triggered from the plastic hinges with high-stress levels.

3. 3D Printing Scale-Type Protective Composite Textiles.
PMID:日期:2025-11-13This study explores the development of a 3D-printed scale-type protective composite textile using biomimetic design principles, inspired by the scale structure of pangolins. Unlike conventional weaving techniques, 3D printing enables precise control over scale geometry (8-12 mm hexagonal units), hierarchical arrangements, and thermoplastic polyurethane (TPU) filler gradients (10-20 wt%), achieving a record puncture resistance of 56.1 N against 12G needles. Aimed at enhancing personal protective equipment, the scale-structured fabric offers improved puncture resistance, flexibility, and breathability. A systematic investigation into different scale configurations, material types, and infill densities reveals the optimal balance between stability and energy absorption. The results indicate that low-fill TPU scales exhibit the best puncture resistance while maintaining sufficient flexibility and air permeability. The study demonstrates the potential of biomimetic 3D-printed textiles as an innovative solution for lightweight, customizable, and efficient PPE materials.

4. A simple, efficient technique to make colon crypt gels for 3D models.
PMID:日期:2025-10-23An colon model, particularly one suited to high throughput screening, has the potential to enhance understanding of cellular mechanisms and functions important in intestinal health and can be used for drug testing and drug permeation studies. While extensively studied, traditional monolayered cultures using immortalized colon cancer cell lines on transwell plates fail to accurately replicate the native intestinal epithelium's complex architecture. To address this limitation, we have developed a novel, facile photopolymerization technique to fabricate scaffolds that closely resemble colon crypts. We have further developed a method using screen printing to be able to coat these scaffolds while preserving the crypt architecture in order to vary the surface chemistry of these systems. This paper focuses on the development of three-dimensional crypt models that can be made with simple equipment and with chemical precursors that are commercially available to make building tissue models more accessible to the broader research community.

5. Direct Tensile Behavior of Three-Dimensional-Printable Steel Fiber-Reinforced Ultrahigh Performance Concrete.
PMID:日期:2025-10-17To investigate the tensile behavior of 3D-printed ultrahigh performance concrete (UHPC), this study developed a 3D-printable steel fiber-reinforced UHPC with a cube compressive strength of up to 115 MPa. Through direct tension tests on dogbone specimens and computed tomography scanning, the influence of the 3D printing methods, specimen thickness and number of specimen layers on the failure mode, cracking strength, peak strength, energy absorption, and orientation of steel fibers in 3D-printed UHPC was analyzed in detail. The results indicate that under direct tension, the failure mode of the 3D-printed UHPC specimens remained in the tensile test section, with no significant difference from those of the cast UHPC specimens. After cracking, a large number of steel fibers were observed in the cracks of the 3D-printed UHPC specimens, forming the effect of a "steel fiber bridge" and exhibiting a trend of directional orientation along the printing direction. This was notably different from the relatively random orientation of steel fibers in the cast specimens. The experimental results show that with 3D printing preparation, the orderly arrangement of steel fibers could significantly improve the tensile performance of UHPC. Moreover, by reducing the nozzle thickness, the steel fibers can be distributed in a wide range along the printing direction. Therefore, the peak tensile stress, peak strain, and energy absorption values of the 3D-printed UHPC specimens could be significantly increased.

6. Flexible 3D-Printable Materials for Application in Medical Research: A Comprehensive Comparison of Commercially Available Materials.
6. 用于医学研究的柔性3D打印材料：商用材料的综合比较PMID:日期:2025-10-17Additive manufacturing has become an important tool in modern medicine with numerous applications such as therapy planning, medical device prototyping and testing, and basic research. While the range of available materials continues to grow, the field of elastic printable materials for medical applications has not been fully explored. Therefore, this study focuses on the comparison of six commercially available flexible printing materials regarding their usability in the medical field. Surface of printed parts for all materials were analyzed directly after printing by scanning electron microscopy. The mechanical behavior was evaluated by uniaxial tensile tests, shore A hardness, and vascular compliance analysis. The degradation effects of the solvents water, glycerin, and ethanol were analyzed over a period of 7 days. The impact of different sterilization protocols (steam, plasma, ethylene oxide) was determined by tensile testing and surface imaging. Cytotoxicity was evaluated by a WST-1 proliferation assay with human endothelial cells. Microscopic imaging revealed a uniform surface with characteristic topologies depending on the printing technique. Different sterilization techniques revealed good results, however, pure silicone material TrueSil showed complete mechanical failure after plasma sterilization. All materials demonstrated high resistance to water and glycerin exposure with only slight weight changes. Ethanol exposure led to significant increases in wet weight with Agilus30 reaching a weight increase of 104.6%. All materials except Aceo showed a decrease in dry weight after ethanol exposure. Formlabs' Flexible 80A and Elastic 50A, as well as Agilus30, showed high cytotoxicity with no cell viability after 24 h. Aceo and TrueSil silicone materials revealed adequate cytocompatibility with viable cells even after 7 days. Static and dynamic vascular elasticity of all tested materials revealed linear elastic behavior. The tested materials offer unique material properties for different use cases, with the recapitulation of vascular elasticity still being a weak point of current printing technologies.

7. Melt-Extrusion Additive Manufacturing for Tissue Engineering: Applications and Limitations.
PMID:日期:2025-10-17The application of additive manufacturing techniques has increased over the years in almost all production fields, thanks to the possibility of creating objects from scratch and with the desired shape, with no need for molds or complex machinery typical of subtractive manufacturing. This success has concerned the biomedical world as well, where melt-based methods represent the golden standard to produce scaffolds for hard-tissue engineering. Despite the large number of studies present in the literature on scaffold production, the fabrication process is still affected by drawbacks and limitations, which hinders the standardization and upscaling to the industrial level. In this review, we briefly present the history of additive manufacturing and the reasons of its success, with particular reference to the tissue engineering and regenerative medicine world. We then proceed to highlight the current factors limiting the straightforwardness of the production process and affecting the quality and the performance of the manufactured scaffolds. Eventually, we suggest potential strategies to increase the level of control during manufacturing and to improve the biomimicry of the fabricated constructs, with the goal of obtaining a more optimal workflow.

9. Biopolymer Hydroxypropyl Methylcellulose-Based Filaments Prepared by Hot-Melt Extrusion Suitable for Fused Deposition Modeling 3D Printing of Personalized Capsules.
PMID:日期:2025-10-17Materials based on the hydroxypropyl methylcellulose mixed with different biopolymers (BioP; 5 w% of chitosan, sodium alginate, apple pectin, or citrus pectin) were processed by hot-melt extrusion and 3D printing to produce capsules intended for controlled drug release. Microscopic analyses confirmed significant impact of BioP on the processing temperatures and quality of the 3D printing. The capsules' chemical composition had a more significant impact on the dissolution profiles in acidic and neutral media, which are a robust function of the intermolecular bonds and swelling characteristics of the particular BioP (as indicated by the combined results of Raman spectroscopy, differential scanning calorimetry [DSC], and thermogravimetry). The capsules of all tested compositions retained the model drug for 120 min in pH 1.2, i.e., fulfilled the condition of targeting the small intestine. The presence of the particular BioP was found to be particularly beneficial in the development of personalized capsules for oral administration. The addition of both pectins led to a relatively fast pH-independent release of the model drug and has the potential applications in the targeting of the duodenum or jejunum. The capsules containing alginate and chitosan exhibited later initial release in pH 1.2, guaranteeing an unaltered passage through the stomach environment.

10. Embedding of Liquids into Water-Soluble Materials via Additive Manufacturing for Timed Release.
PMID:日期:2025-10-17The ability to customize products with additive manufacturing allows manufacturers to meet the unique requirements and functionality for individual applications. By printing dissolvable materials as a matrix material, the release of active agents over time can be tailored on a per part basis by varying both geometry and printed material properties. Direct printing of actives via filament material extrusion is challenging because many active agents become inactive at the elevated temperatures found in the melt-based process. This limitation is circumvented by embedding the active agents into designed voids of a printed water-soluble capsule. In this work, this process is demonstrated by the deposition of liquids and powders into thin-walled, water-soluble, printed structures. The authors demonstrate the ability to tune dissolution time by varying the thickness of a printed part's walls in order to create a delay in release and by creating parts with multiple chambers to initiate a multistaged release. This ability provides opportunities for creating customized containers for the prescribed release of liquid and powdered active agents.
