However, earth materials applications in additive manufacturing have been limited to thick mass assemblies with little to no fiber reinforcement. The addition of natural plant fibers within earth-based mixtures may advantageously increase ductility while allowing for lightweight assembly types, such as thin and perforated elements. This article presents a novel research development on natural, raw, and untreated earth-fiber compositions with maximized wheat straw fiber content for 3D-printed lightweight architectural tiling applications. Initiated with an experimental printability apparatus of a range of mix designs, a printable \"light straw clay\" mixture is defined through extrudability and buildability tests. Then, combining the digital craft of weaving with natural fibers for earthen lightweight artifacts, a geometric analysis explores potential super lightweight and structurally sound tessellations to allow for minimum material in the production of perforated panels. The third phase of the research included structural bending tests to assess the number of layers required for the final tile production. Finally, the resulting 3D-printed modular components were assembled to create a lightweight installation, hung and exhibited with an interplay of light and shade. By maximizing co-product vegetable fiber content within an earthen and bio-based paste, this research aims to increase the carbon storage capabilities of digital earth construction while enhancing its lightness and tensile possibilities. Learning from vernacular \"recipes\" of natural earth- and fiber-based construction, the developed paper-thin partition assemblage presented in this article contributes to wider possibilities of natural, nonconventional, and radically low-carbon material systems and geometries in digital fabrication.","PeriodicalId":54341,"journal":{"name":"3D Printing and Additive Manufacturing","volume":"12 2","pages":"88-97"},"PeriodicalIF":2.1,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12038327/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144052913","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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 shape-change transformation of the 4DP composite mechanism is preprogrammed by controlling the printing process parameters and the design of the print-path pattern. Until now, most 4DP approaches involving Wood Polymer Composite (WPCs) have focused on planar actuators featuring a bilayer structure composed of laminar layers with distinct material properties. These mechanisms show a laminar initial rest state, presenting as flat objects, and can only achieve a complex three-dimensional shape when subjected to the moisture variations stimulus. The presented research highlights the development of a multistage printing method that expands the capabilities of three-axis printers to enable the 4DP of mechanism with complex nonplanar rest-state geometries. The new technical capabilities of this method are demonstrated here through the creation and testing of novel nonlaminar 4DP mechanisms that harness their unique doubly curved rest-state geometry to achieve kinematic amplification. We expect that this approach can greatly improve the range and complexity of 4DP mechanisms that can be developed using the commonly available three-axis printers.","PeriodicalId":54341,"journal":{"name":"3D Printing and Additive Manufacturing","volume":"12 2","pages":"141-154"},"PeriodicalIF":2.5,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12038350/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143991900","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This case study connects machine vision-based surveying of damaged panels with repair through conformal 3D printing. This deployment of bio-based materials aims to enable additive manufacturing as a method for disrupting the sharp delineation between fabrication and repair leading to new practices of continual construction. With point of departure in our bespoke systems for 3D printing and unique biopolymer composites, we examine how their particular material characteristics allow for material adhesion and buildup and how novel methods for iterative 3D printing can support design integrated strategies of repair. As part of this process, we include the sociotechnological dimension, as human-in-the-loop decision-making becomes part of the material surveying regimes necessary for damage detection.

While several products have begun to gain popularity as biodegradable or compostable plastics, these often still negatively impact terrestrial and aquatic environments, as they frequently require precise conditions in order to fully decompose. Furthermore, standards for measuring biodegradation rates are often complex and poorly representative of real disposal sites, limiting their widespread use and applicability. In this study, we present four simple tests to assess the environmental degradability of materials without specialized equipment and demonstrate them with a series of 3D printable biotic composites composed of pectin, chitosan, and cellulose, abundant and organic biopolymers known to be degradable by common microorganisms. Five different compositions were degraded in live soil, worm burial, high humidity, and aqueous environments, and demonstrated rapid degradation with up to 100% mass loss after 21 days for a pectin-based material buried in worm-laden oil. Degradability was further found to be tunable, with decreasing degradation rate as chitosan content increased. Our results confirm that biotic composites degrade more rapidly than conventional plastics and provide accessible methods that can enable more widespread material testing for the development of sustainable material alternatives, especially to gather basic environmental degradation information representative of typical solid waste discard conditions. We anticipate that these degradation methods and the materials degraded therein will provide further impetus for reducing waste from 3D printing and for considering end of life when designing products.","PeriodicalId":54341,"journal":{"name":"3D Printing and Additive Manufacturing","volume":"12 2","pages":"122-130"},"PeriodicalIF":2.5,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12038357/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143991880","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Specifically, fused filament fabrication (FFF) is notable for its liquid and powder-free process, which is suitable for vacuum and low-gravity conditions. However, the anisotropic strength of FFF parts limits their use. This research presents a methodical approach to improve the mechanical strength of 3D-printed carbon fiber (CF)-reinforced polyether ether ketone (PEEK) components, aiming for improved mechanical strength by applying in-process laser heating. CF PEEK is selected for its exceptional strength, durability, and heat resistance. The core of this laser technique is to increase the interface temperature, slowing down the cooling phase, which promotes polymer chain movement and entanglement, leading to enhanced mechanical properties. This method significantly boosts the mechanical strength of 3D-printed PEEK in the build direction from 9.3 MPa to 60.5 MPa, with the strain increasing by 150%. Additionally, there are notable differences in fracture behavior: the control sample fractures at the interlayer interface, while the laser-treated sample fractures within the layer. Adopting this advanced approach could address the current limitations of FFF 3D printing in manufacturing and enable FFF to serve fields that require mechanical strength and small-batch production. This technique has the potential to extend polymer additive manufacturing to fields requiring high-temperature, high-strength composites, such as in-space manufacturing/assembly, small-batch production for aerospace parts, medical components, and prototypes.","PeriodicalId":54341,"journal":{"name":"3D Printing and Additive Manufacturing","volume":"13 4","pages":"339-345"},"PeriodicalIF":2.5,"publicationDate":"2025-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13428131/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148654863","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One approach used to achieve these improvements is the application of multi-lattice structures, where the macroscale performance relies on the detailed design of mesostructural lattice elements. Many current approaches to designing such structures use data-driven design to generate multi-lattice transition regions, making use of machine learning models that are informed solely by the geometry of the mesostructures. However, it remains unclear if the integration of mechanical properties into the dataset used to train such machine learning models would be beneficial beyond using geometric data alone. To address this issue, this work implements and evaluates a hybrid geometry/property variational autoencoder (VAE) for generating multi-lattice transition regions. In our study, we found that hybrid VAEs demonstrate enhanced performance in maintaining stiffness continuity through transition regions, indicating their suitability for design tasks requiring smooth mechanical properties.","PeriodicalId":54341,"journal":{"name":"3D Printing and Additive Manufacturing","volume":"12 1","pages":"23-35"},"PeriodicalIF":2.1,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11937804/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143733212","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
