Biomaterials Adapted to Vat Photopolymerization in 3D Printing: Characteristics and Medical Applications.

Along with the rapid and extensive advancements in the 3D printing field, a diverse range of uses for 3D printing have appeared in the spectrum of medical applications. Vat photopolymerization (VPP) stands out as one of the most extensively researched methods of 3D printing, with its main advantages being a high printing speed and the ability to produce high-resolution structures. A major challenge in using VPP 3D-printed materials in medicine is the general incompatibility of standard VPP resin mixtures with the requirements of biocompatibility and biofunctionality. Instead of developing completely new materials, an alternate approach to solving this problem involves adapting existing biomaterials. These materials are incompatible with VPP 3D printing in their pure form but can be adapted to the VPP chemistry and general process through the use of innovative mixtures and the addition of specific pre- and post-printing steps. This review's primary objective is to highlight biofunctional and biocompatible materials that have been adapted to VPP. We present and compare the suitability of these adapted materials to different medical applications and propose other biomaterials that could be further adapted to the VPP 3D printing process in order to fulfill patient-specific medical requirements.

Three-Dimensional Printing of Biomass–Fungi Biocomposite Materials: The Effects of Mixing and Printing Parameters on Fungal Growth

Biomass–fungi biocomposite materials are derived from sustainable sources and can biodegrade at the end of their service. They can be used to manufacture products that are traditionally made from petroleum-based plastics. There are potential applications for these products in the packaging, furniture, and construction industries. In the biomass–fungi biocomposite materials, the biomass particles (made from agricultural waste such as hemp hurd) act as the substrate, and a network of fungal hyphae grow through and bind the biomass particles together. Typically, molding-based methods are used to manufacture products using these biocomposite materials. Recently, the authors reported a novel extrusion-based 3D printing method using these biocomposite materials. This paper reports a follow-up investigation into the effects of mixing parameters (mixing time and mixing mode) on fungal growth in biomass–fungi mixtures prepared for 3D printing and the effects of printing parameters (printing speed and extrusion pressure) on fungal growth in printed samples. The fungal growth was quantified using the number of fungal colonies that grew from samples. The results show that, when mixing time increased from 15 to 120 s, there was a 52% increase in fungal growth. Changing from continuous to intermittent mixing mode resulted in an 11% increase in fungal growth. Compared to mixtures that were not subjected to printing, samples printed with a high printing speed and high extrusion pressure had a 14.6% reduction in fungal growth, while those with a low printing speed and low extrusion pressure resulted in a 16.5% reduction in fungal growth.

Light Sheet-Based Laser Patterning Bioprinting Produces Long-Term Viable Full-Thickness Skin Constructs.

Tissue engineering holds great promise for biomedical research and healthcare, offering alternatives to animal models and enabling tissue regeneration and organ transplantation. 3D bioprinting stands out for its design flexibility and reproducibility. Here, an integrated fluorescent light sheet bioprinting and imaging system is presented that combines high printing speed (0.66 mm3 /s) and resolution (9µm) with light sheet-based imaging. This approach employs direct laser patterning and a static light sheet for confined voxel crosslinking in photocrosslinkable materials. The developed bioprinter enables real-time monitoring of hydrogel crosslinking using fluorescent recovery after photobleaching (FRAP) and brightfield imaging as well as in situ light sheet imaging of cells. Human fibroblasts encapsulated in a thiol-ene click chemistry-based hydrogel exhibited high viability (83% ± 4.34%) and functionality. Furthermore, full-thickness skin constructs displayed characteristics of both epidermal and dermal layers and remained viable for 41 days. The integrated approach demonstrates the capabilities of light sheet bioprinting, offering high speed, resolution, and real-time characterization. Future enhancements involving solid-state laser scanning devices such as acousto-optic deflectors and modulators will further enhance resolution and speed, opening new opportunities in light-based bioprinting and advancing tissue engineering.

SiCp/AlSi10Mg composites with simultaneously enhanced tensile strength and ductility fabricated by laser powder bed fusion additive manufacturing

Currently, SiCp/Al composites fabricated by laser powder bed fusion (LPBF) suffer from poor plasticity caused by their low density and a great deal of coarse needle-like brittle phases, which seriously limits their application in aerospace field. High scanning speed can shorten the reaction time between SiC and Al liquid due to the short existence time of molten pool, effectively suppressing the nucleation and growth of these needle-like brittle phases. Therefore, an LPBF with a high-speed scanning printing strategy was proposed to fabricate micro-SiCp/Al composites in this study. The effects of energy density (E) on the densification, microstructure and mechanical properties of the composites were studied systematically. The contradiction that the higher the density, the more and coarser needle-like phases produced was successfully resolved. The micro-SiCp/Al composites with simultaneously enhanced strength and ductility were achieved at a proper E of 47 J/mm3, whose tensile strength and elongation reached 356.7 ± 5.0 MPa and 11.6 ± 0.4%, respectively. Among them, the elongation is almost 4 times the maximum value reported in the literature, which is mainly attributed to the extremely high compactness without any visible defects, the moderate dissolution and uniform distribution of SiC particles, the refined grains, a few nano-sized Al4C3 and Al4SiC4, and the interfacial structure SiC–Al4SiC4–Al with high interfacial bonding strength. Because these factors greatly reduced the stress concentration inside the composites and made the stress evenly distributed during loading, thus improving the ductility. Especially these in-situ synthesized Al4C3 and Al4SiC4 can not only promote the transformation of α-Al columnar grains to cellular grains, but also hinder the bending and motion of dislocations, playing a role in grain refinement and dispersion strengthening. The fracture mode of the composites is ductile fracture. Our work provides theoretical guidance and technical support for fabricating SiCp/Al composites with simultaneously enhanced strength and ductility.

Functional additive manufacturing of large-size metastructure with efficient electromagnetic absorption and mechanical adaptation

Broadband microwave absorption as a hot research topic plays important roles on electromagnetic compatibility, electromagnetic radiation protection and radar detection disguise. However, traditional molding method is difficult to fabricate large-size curving structures for broadband microwave absorption. Herein, the material extrusion with high-speed printing process was effective to manufacture large-size metastructures for broadband microwave absorption. The polylactic acid was mixed and extruded with nano pyrolytic carbon in high temperature to manufacture functional filaments with high dielectric loss. The printed metastructure integrated with 0.5 mm quartz fiber reinforced composite (QFRC) achieved -10 dB broadband microwave absorption in 3.03-18 GHz and effective load bearing performance in tensile and flexural tests. Severe impedance mismatch brought by QFRC was overcome by appropriate structure design and high-speed printing technique. The proposed design-manufacturing closed loop is a promising approach to fabricate aircraft skin with broadband microwave absorption performance and suitable aerodynamic properties for heavy unmanned aerial drones.

Fabrication of Ni-microstructure through electrochemical deposition using 3D printed solution flow type microdroplet cell

Electrochemical 3D printing of electrical conductors with microscale fabrication grasps large capacities for future industrial applications. Low-cost, and eco-friendly electrochemical additive manufacturing techniques for high-speed printing metals are required. In this work, 3D-printed solution-flow type microdroplet cell (SF-MDC) is proposed as a novel electrochemical deposition technique for fabricating of Ni microstructures on the Cu substrate in localized areas. The influence of current density on the morphology and grain size of Ni electrodeposition was studied. The effect of scanning speed on the deposition thickness was also examined. The surface morphology and crystal structures of the deposited Ni layers were analyzed by scanning electron microscope (SEM) and X-ray diffraction (XRD) techniques. The results showed that as the current density increased, large nodule grain size microstructures with heterogeneous morphology were obtained. The XRD result showed that the deposited Ni crystal was characterized by face-centered cubic (FCC) structure. A thickness of 93.1 µm, 63.5 µm, and 46.3 µm were printed at scanning speeds of 3 µm s−1, 5 µm s−1, and 10 µm s−1, respectively. Free-standing 3D Ni micro-rods were fabricated on a Cu substrate using SF-MDC.

Parametric investigation and optimisation of mechanical properties of thick tri-material based composite of PLA-PETG-ABS 3D-printed using fused filament fabrication

Tri-material and tri-layered composites find numerous applications in the biomedical, aerospace, and automotive industries. However, such composites face challenges when fabricated through conventional methods (Electrospinning, hand lay-up, Film Casting, In-situ polymerization), such as interface bond strength, strength-to-mass ratio, etc. Additive manufacturing can be used to fabricate such composites to overcome these challenges. In this study, tensile samples of tri-material based 3D-printed (TM3DP) polymer composite of polylactic acid (PLA), polyethylene terephthalate glycol (PETG), and acrylonitrile butadiene styrene (ABS) were successfully processed using fused filament fabrication (FFF) for the first time. The composite is fabricated such that 33.333% PLA was printed first, followed by 33.333% PETG, and, in the end, 33.333% ABS so that PETG is sandwiched between PLA and ABS. The effect of FFF processing parameters on the tensile properties of the printed composites was investigated. After preliminary experiments and a literature review, infill density (ID), printing speed (PS), and layer thickness (LT) were selected as the main processing parameters. The tensile strength (TS) and tensile strain (ℇ) were selected as the outputs (responses) of this study. Tensile testing was performed after printing composite tensile samples on Instron Universal Testing Machine (5 KN). An analysis of variance (ANOVA) was also performed to check the significance of FFF process parameters. The results concluded that the selected FFF process parameters were significant in the interaction state of both tensile properties. Scanning electron microscopy (SEM) and optical microscopy were also performed, which indicated that various defects, including micropores, voids, and micro / major delamination occurred in conditions of high LT, high PS, and low ID. This resulted in a low TS of 27.1 MPa and ℇ of 0.5 mm/mm. No major defects were observed under high LT, high PS, and high ID, which resulted in the highest TS of 39.5 MPa and ℇ of 0.95. Finally, optimum conditions were suggested for fabricating the thick TM3DP composite samples, believed to enhance the TS-to-mass ratio by 16.4% compared to the single solid 3D-printed base materials.

Fully Printed, High-Temperature Micro-Supercapacitor Arrays Enabled by a Hexagonal Boron Nitride Ionogel Electrolyte.

The proliferation and miniaturization of portable electronics require energy-storage devices that are simultaneously compact, flexible, and amenable to scalable manufacturing. In this work, mechanically flexible micro-supercapacitor arrays are demonstrated via sequential high-speed screen printing of conductive graphene electrodes and a high-temperature hexagonal boron nitride (hBN) ionogel electrolyte. By combining the superlative dielectric properties of 2D hBN with the high ionic conductivity of ionic liquids, the resulting hBN ionogel electrolyte enables micro-supercapacitors with exceptional areal capacitances that approach 1 mF cm-2 . Unlike incumbent polymer-based electrolytes, the high-temperature stability of the hBN ionogel electrolyte implies that the printed micro-supercapacitors can be operated at unprecedentedly high temperatures up to 180 °C. These elevated operating temperatures result in increased power densities that make these printed micro-supercapacitors particularly promising for applications in harsh environments such as underground exploration, aviation, and electric vehicles. The combination of enhanced functionality in extreme conditions and high-speed production via scalable additive manufacturing significantly broadens the technological phase space for on-chip energy storage.

Investigation of effects of processing parameters on the impact strength and microstructure of thick tri-material based layered composite fabricated via extrusion based additive manufacturing

Additive manufacturing composites have been employed in applications including, aerospace, automotive industries etc. and there are a number of properties required for such applications including better impact strength (I-S) which is the resistance to withstand impact loading. The present study investigates for the first time the effects of processing parameters on the I-S of thick tri-material based layered (Tmbl) composite of Polylactic acid (PLA), Polyethylene Terephthalate Glycol (PETG), and Acrylonitrile Butadiene Styrene (ABS) fabricated via Fused Filament Fabrication (FFF). 3 process parameters are varied in three levels each, whereas the I-S is chosen as output. Analysis of variance (ANOVA) is conducted. The surface plots of the significant parameter interactions are plotted showing the effects-trends of each variable on the I-S of the composite and various inter-layer, macro and micro observation of the composite was also performed using optical microscopy. It was observed that various shortcomings such as pores, delamination, peeling-like structure formation occurred at high layer thickness (t), high printing speed (v) and low infill density (ρ) whereas, there was absence of substantial defects at high ρ. Therefore, it was concluded that the selected parameters are significantly affecting the I-S of the composite. At the end, optimization of processing conditions was performed which resulted in enhanced I-S to weight ratio as compared to the highest I-S of single solid three dimensional (3d) printed base material.

This study presents the effect of different printing parameters including printing speed, extrusion rate, and inter-filament overlapping distance on inter-filament bonding, inter-filament voids, and geometrical deviation in concrete 3D printed structures using Response Surface Methodology. Moreover, this study adopts a central composite design to generate a set of experimental runs and develop a second-order polynomial equation to quantify the effect of printing parameters. Results show that high inter-filament bonding with minimal inter-filament void and geometrical deviation can be achieved at high printing speed and low extrusion rate with 1/8Nd (2.5 mm) inter-filament overlapping distance.

High-Speed Printing of Narrow-Band-Gap Sn-Pb Perovskite Layers toward Cost-Effective Manufacturing of Optoelectronic Devices.

Narrow-band-gap Sn-Pb perovskites have emerged as one of the most promising solution-processed near-infrared (NIR) light-detection technologies, with the key figure-of-merit parameters already rivaling those of commercial inorganic devices, but maximizing the cost advantage of solution-processed optoelectronic devices depends on the ability to fast-speed production. However, weak surface wettability to perovskite inks and evaporation-induced dewetting dynamics have limited the solution printing of uniform and compact perovskite films at a high speed. Here, we report a universal and effective methodology for fast printing of high-quality Sn-Pb mixed perovskite films at an unprecedented speed of 90 m h-1 by altering the wetting and dewetting dynamics of perovskite inks with the underlying substrate. A line-structured SU-8 pattern surface to trigger spontaneous ink spreading and fight ink shrinkage is designed to achieve complete wetting with a near-zero contact angle and a uniform dragged-out liquid film. The high-speed printed Sn-Pb perovskite films have both large perovskite grains (>100 μm) and excellent optoelectronic properties, yielding highly efficient self-driven NIR photodetectors with a large voltage responsivity over 4 orders of magnitude. Finally, the potential application of the self-driven NIR photodetector in health monitoring is demonstrated. The fast printing methodology provides a new possibility to extend the manufacturing of perovskite optoelectronic devices to industrial production lines.

High-speed 3D printing for microfluidics: Opportunities and challenges

Traditional methods for the fabrication of microfluidic devices lead to the produced devices being expensive, involving time-consuming fabrication processes, and being limited in their design choices. In this review, we present the opportunities and challenges faced by 3D printing for microfluidic applications, with a key interest in the overall speed of the fabrication process. The development of high-speed methods for additive manufacturing (AM) of microfluidic devices is of interest to reduce the barrier of entry by further reducing the cost and fabrication time. This review investigates the key benefits of AM for microfluidic device fabrication, such as greater freedom of design and more complex devices to be created than is possible with traditional fabrication methods. Through complex three-dimensional microfluidic designs, it is possible to integrate features into a microfluidic device that traditionally would require external equipment, resulting in an even lower total cost of operating a microfluidic device leading to low-cost field-based applications. There are many methods for the AM of microfluidic devices: Stereolithography (SLA), Digital Light Processing (DLP), Material Jetting (MJ), and Fused Deposition Modelling (FDM). This review explores these various technologies and their suitability for the high-speed fabrication of microfluidic devices with this review showing that the preferred AM method selected for microfluidic device fabrication depends on desired use case of the microfluidic device.

High-Speed and High-Resolution 3D Printing of Self-Healing and Ion-Conductive Hydrogels via μCLIP

Conductive and self-healing (SH) hydrogels have been receiving continuous attention, which could broaden the design of ionotronic devices for health monitoring systems and soft robots with the ability to repair damage autonomously. So far, three-dimensional (3D) fabrication of such SH hydrogels is mainly limited to traditional molding/casting or extrusion-based 3D printing methods, which limits the formation of sophisticated structures with high-resolution features. Furthermore, the need of external stimuli (e.g., water, heat, and pH change) to achieve SH behavior could restrict their wide application. Herein, we report an ion-conductive SH hydrogel suitable for a home-built high-resolution and high-speed 3D printing process, micro continuous liquid interface production (μCLIP). This material system relies on interpenetrating polymer networks (IPN) hydrogel formed by physically cross-linked poly(vinyl alcohol) combined with chemically/ionically cross-linked poly(acrylic acid) and ferric chloride. By carefully optimizing the resin’s composition, we can balance high-resolution printability and superb SH capability, at the same time manifesting sufficient ion conductivity. Specifically, complex 3D structures with microscale features (down to 100 μm) can be printed at speeds up to 16.5 μm s–1. Upon damage occurs, hydrogen bonds within hydroxyl and carboxyl groups, as well as ionic bonds generated from ferric ions, contribute together to achieve fast and high efficiency SH, which can restore 90% (100%) of the original mechanical strength at room temperature within 4 h (8 h) without any external stimulus. In addition, both the as-printed and self-healed hydrogels manifest superior ion conductivity and stretchability. Therefore, the SH hydrogels can be rapidly printed and tailored as customized wearable sensors, and the sensing capabilities were quantitatively investigated and compared. In terms of applications, SH hydrogel-based knuckle sensors were prototyped to detect a finger’s folding and unfolding motions.

Introducing Dynamic Bonds in Light‐based 3D Printing

AbstractLight‐based 3D printing has received significant attention due to several advantages including high printing speed and resolution. Along with the development of new technologies, material design is key for the next generation of light‐based 3D printing. Conventional printable polymeric materials, also known as photopolymers or photoresins, often lead to thermosets–polymer networks cross‐linked by permanent covalent bonds which bring limited adaptability and restricted reprocessability. Dynamic bonds that can reversibly break and reform enable network rearrangement, thereby offering unprecedented properties to the materials such as adaptability, self‐healing, and recycling capabilities. Hence, introducing dynamic bonds into materials for light‐based 3D printing is a promising strategy to further expand and meet the diverse application scenarios of 3D printed multi‐functional materials and moreover meet more demanding sustainable and nature‐inspired design considerations (e.g., adaptability and self‐healing). Herein, an overview of recent advances in dynamic photopolymers for light‐based 3D printing, aiming to bridge these two promising research fields is presented. Importantly, the current challenges are also analyzed and perspectives for further developing dynamic photopolymers for light‐based 3D printing and their potential applications are provided.

Towards Digital Twin Implementation in Roll-To-Roll Gravure Printed Electronics: Overlay Printing Registration Error Prediction Based on Printing Process Parameters

Roll-to-roll gravure (R2Rg) has become highly affiliated with printed electronics in the past few years due to its high yield of printed thin-film transistor (TFT) in active matrix devices, and to its low cost. For printing TFTs with multilayer structures, achieving a high-precision in overlay printing registration accuracy (OPRA) is a key challenge to attain the high degree of TFT integration through R2Rg. To address this challenge efficiently, a digital twin paradigm was first introduced in the R2Rg system with an aim to optimize the OPRA by developing a predictive model based on typical input variables such as web tension, nip force, and printing speed in the R2Rg system. In our introductory-level digital twin, errors in the OPRA were collected with the variable parameters of web tensions, nip forces, and printing speeds from several R2Rg printing processes. Subsequently, statistical features were extracted from the input data followed by the training of a deep learning long-short term memory (LSTM) model for predicting machine directional error (MD) in the OPRA. As a result of training the LSTM model in our digital twin, its attained accuracy of prediction was 77%. Based on this result, we studied the relationship between the nip forces and printing speeds to predict the MD error in the OPRA. The results indicated a correlation between the MD error in the OPRA and the printing speed, as the MD error amplitude in the OPRA tended to decline at the higher printing speed.

Single-vat single-cure grayscale digital light processing 3D printing of materials with large property difference and high stretchability

Multimaterial additive manufacturing has important applications in various emerging fields. However, it is very challenging due to material and printing technology limitations. Here, we present a resin design strategy that can be used for single-vat single-cure grayscale digital light processing (g-DLP) 3D printing where light intensity can locally control the conversion of monomers to form from a highly stretchable soft organogel to a stiff thermoset within in a single layer of printing. The high modulus contrast and high stretchability can be realized simultaneously in a monolithic structure at a high printing speed (z-direction height 1 mm/min). We further demonstrate that the capability can enable previously unachievable or hard-to-achieve 3D printed structures for biomimetic designs, inflatable soft robots and actuators, and soft stretchable electronics. This resin design strategy thus provides a material solution in multimaterial additive manufacture for a variety of emerging applications.

The article describes the technology of building elements of unmanned aerial vehicles (UAV) based on the use of additive technologies (AT). AT opened a fundamentally new direction in the concept of UAV manufacturing, which makes it possible to obtain a final product of a given shape and size based on a digital prototype. The modern equipment used in JSC is constantly being improved and allows for high printing speeds to increase the quality of the product at relatively low costs. The use of AT makes it possible to significantly reduce the weight of UAV elements due to the reduction of material costs. The article examines the technological process of 3D printing of UAV elements and the technological scheme of materials selection for the manufacture of UAV elements. In the course of the conducted research, a number of problems related to the need to improve the process of 3D printing of complex elements of UAVs, in order to effectively use the latest additive 3D printing technologies in modern production in combat conditions, were identified. The results of test printing, plastic tests and calculations made it possible to develop a general methodology for the production of UAV elements using additive technologies. The introduction of additive technologies for the production of UAV elements in the field will contribute to solving a wide range of combat tasks. It has been established that the use of additive technologies will entail the adjustment of UAV design principles, the development of printing technologies, the use of new construction strategies, the emergence of new technologies related to 3D printing. The analysis of quality control mechanisms for the development of UAV elements shows that the technological scheme for the selection of composite material is an important element in the 3D printing of modern UAVs and their components. It was determined that with the improvement of technological equipment and the development of methods of material selection for the manufacture of UAV elements, the direction of creating new UAVs with the help of AT will steadily expand.

A hybrid ANN/PSO optimization of material composition and process parameters for enhancement of mechanical characteristics of 3D-printed sample

PurposeThis paper aims to study the effects of inorganic CaCO3 nanoadditives in the polylactic acid (PLA) matrix and fused filament fabrication (FFF) process parameters on the mechanical characteristics of 3D-printed components.Design/methodology/approachThe PLA filaments containing different levels of CaCO3 nanoparticles have been produced by mix-blending/extrusion process and were used to fabricate tensile and three-point bending test samples in FFF process under various sets of printing speed (PS), layer thickness (LT), filling ratio (FR) and printing pattern (PP) under a Taguchi L27 orthogonal array design. The quantified values of mechanical characteristics of 3D-printed samples in the uniaxial and the three-point bending experiments were modeled and optimized using a hybrid neural network/particle swarm optimization algorithm. The results of this hybrid scheme were used to specify the FFF process parameters and the concentration of nanoadditive in the matrix that result in the maximum mechanical properties of fabricated samples, individually and also in an accumulative response scheme. Diffraction scanning calorimetry (DSC) tests were conducted on a number of samples and the results were used to interpret the variations observed in the response variables of fabricated components against the FFF parameters and concentration of CaCO3 nanoadditives.FindingsThe results of optimization in an accumulative scheme showed that the samples of linear PP, fabricated at high PS, low LT and at 100% FR, while containing 0.64% of CaCO3 nanoadditives in the matrix, would possess the highest mechanical characteristics of 3D-printed PLA components.Originality/valueFFF is a widely accepted additive manufacturing technique in production of different samples, from prototypes to the final products, in various sectors of industry. The incorporation of chopped fibers and nanoparticles has been introduced recently in a few articles to improve the mechanical characteristics of produced components in FFF technique. However, the effectiveness of such practice is strongly dependent on the extrusion parameters and composition of polymer matrix.

Effect of ultraviolet post-curing, laser power, and layer thickness on the mechanical properties of acrylate used in stereolithography 3D printing

Three-dimensional (3D) printing technology has developed rapidly in the past few years. This technology is widely used in houses, workpieces, artworks, organs, and even the food industry. Among the multiple 3D printing methods, the stereolithography appearance (SLA) technique is well known for its high printing speed and considerable accuracy. In this research, the optimization parameters of the laser curing technology were applied by changing laser power and molding thickness. The mechanical properties were tested using a tensile test and a compression test of photosensitive resin materials after ultraviolet (UV) curing. The experimental results revealed that increasing the laser power or reducing the molding thickness increased the ultimate tensile strength, tensile Young’s modulus, and compressive strength of the material. However, when the stretch was decreased after UV curing, the strength of the material effectively improved, but the toughness of the material decreased. The abovementioned experimental results will be helpful to researchers for further studies on SLA.
