Digital Light Processing Route for 3D Printing of Acrylate-Modified PLA/Lignin Blends: Microstructure and Mechanical Performance

In this study, digital light processing (DLP) was utilized to generate 3D-printed blends composed of photosensitive acrylate-modified polylactic acid (PLA) resin mixed with varying weight ratios of lignin extracted from softwood, typically ranging from 5 wt% to 30 wt%. The microstructure of these 3D-printed blends was examined through X-ray microtomography. Additionally, the tensile mechanical properties of all blends were assessed in relation to the weight ratio and post-curing treatment. The results suggest that post-curing significantly influences the tensile properties of the 3D-printed composites, especially in modulating the brittleness of the prints. Furthermore, an optimal weight ratio was identified to be around 5 wt%, beyond which UV light photopolymerization experiences compromises. These findings regarding acrylate-modified PLA/lignin blends offer a cost-effective alternative for producing 3D-printed bio-sourced components, maintaining technical performance in reasonable-cost, low-temperature 3D printing, and with a low environmental footprint.

Development of recyclable bio-based epoxy/acrylate blends for liquid crystal display 3D printing

AbstractBio-based epoxy resins are widely utilized in various application fields such as adhesives, coatings, composites, and electrical components, offering comparable performance characteristics to conventional epoxy resins, including high strength, durability, and chemical resistance. The use of bio-based materials in 3D printing has been receiving increasing attention as a means of reducing the environmental impact of this technology, because most formulations available for stereolithography and digital light processing are generally non-renewable. This study aimed to explore the potential of blending a bio-based epoxy resin with a commercial daylight-curable resin at various msss percentages to enhance the thermomechanical properties of 3D-printed parts while adhering to the working principle of liquid crystal display (LCD) printers. The prepared formulations were initially characterized in terms of their thermo-mechanical properties both before and after post-treatments like photo- and thermal-curing. This procedure facilitated a comparison of the various blends based on their mechanical strength, glass transition temperature, and other pertinent properties. Upon identifying the optimal formulation, 3D-printed samples were produced using LCD printing technology. Calorimetric and morphological tests were then carried out to evaluate the thermal stability and microstructure of the printed parts. Overall, the findings of this study indicate that blending recyclable bio-based epoxy resins with commercial ones can lead to enhanced properties in additive manufactured parts. This approach has the potential to promote sustainability in 3D printing by reducing the consumption of non-renewable resources, while still meeting the standard performance required for numerous applications.

Optimized DLP 3D-printed high-resolution nano zirconia-hydroxyapatite scaffold with craniomaxillofacial soft tissue invasion resistance and pro-osteogenic properties via dectin-1/syk inflammatory axis

One major challenge of craniomaxillofacial bone regeneration is the direct contact of subcutaneous fibrous tissue towards bone regenerative region, which results in fast fibroblast invasion and suppression of bone regeneration. Dectin-1, a pattern recognition receptor expressed on activated macrophages, is crucial for directing fibrous invasion. Targeting Dectin-1 and its downstream signaling cascade could be an effective strategy to resist “craniomaxillofacial soft tissue invasion”. Nano zirconia can shelter the essential amino acids of Dectin-1 and was reported to deactivate the inflammation signals. Herein, we succeeded in incorporating nano zirconia into high-resolution 3D hydroxyapatite (HA) scaffolds via modified digital light processing (DLP) technique system. The incorporation of nano zirconia can endow high-resolution HA scaffolds with the capacity of regulating the key structure of extracellular C-type lectin-like domain (CTLD) of dectin-1, proved by computational simulation. This results in inhibiting the dectin-1/syk axis and pro-soft tissue proliferation cytokines production. In vivo experiments further validated the effects of HA/nano zirconia resisting craniomaxillofacial soft tissue invasion and promoting bone regeneration. Our work practices the concept of “soft tissue invasion resisting capacity” via targeting in manipulating dectin-1, which succeeds in attenuating fibrous invasion and craniomaxillofacial bone regeneration. The “soft tissue invasion resisting capacity” could become a valuable biological paradigm of craniomaxillofacial bone biomaterials.

Advancements in DLP 3D printing: High strength alumina toughened zirconia ceramics for biomedical applications

Digital Light Processing (DLP) enables intricate ceramic part production from photosensitive ceramic slurry. While ZrO2 and Al2O3 are commonly studied, their composites are underexplored despite diverse applications. This study investigates fabricating high-strength, fully dense alumina-toughened zirconia (ATZ) parts using a low-cost desktop DLP printer designed for polymer printing. Various ATZ-based ceramic slurries (30, 35, 42.5 vol%) with different binders and dispersants were prepared and evaluated for curing and rheological properties. Promising formulations underwent debinding and sintering, resulting in homogenous microstructures with a well-distributed blend of the two phases. For the doped samples, SEM analysis revealed a good distribution of dopants and elongated dopant grains infused at higher temperatures. The 35 vol% ATZ exhibited exceptional average flexural strength of 1321 MPa, surpassing previous DLP-fabricated composites. This suggests no need for increased solid loading content. The findings demonstrate the potential of DLP in producing high-performance ceramic parts with tailored properties.

Advancements in developing biomaterials for 3D printing photosensitive resins containing quaternary ammonium molecules for enhanced oral healthcare

In this study, we investigated the development of biomaterials tailored for UV-cured 3D printing technology in oral healthcare. Traditionally, 3D-printed oral healthcare products have exhibited imperfections in antimicrobial and anti-pollution properties, limiting their utility. To address this challenge, we synthesised antimicrobial agents incorporating quaternary ammonium groups through a combination of isophorone diisocyanate (IPDI), hydroxyethyl methacrylate (HEMA), and choline chloride. These agents were then blended with diluents, resins, and photoinitiators to create raw materials suitable for UV-curing 3D printing photosensitive resins. Subsequently, the resins were subjected to digital light processing (DLP) 3D printing for curing. The resulting 3D-printed material underwent rigorous mechanical and antimicrobial testing. Our findings demonstrate that the 3D printed compounds, cured through this process, exhibited exceptional hardness, tensile properties, antimicrobial characteristics, and long-lasting antimicrobial durability. These developments promise widespread adoption and application within the oral healthcare field.

Novel 3D printed PZT-based piezoceramics for piezoelectric energy harvesting via digital light processing

Structure optimization is a highly effective way for enhancing the power output of piezoceramics. However, due to the high hardness and brittleness of these materials, traditional manufacturing methods are limited in their ability to optimize structures. Moreover, achieving new designs using the emerging digital light processing (DLP) technology is hindered by poor curing performance of piezoceramic slurry. To overcome these issues, this study proposes an innovative strategy of using the original powders as printing materials for DLP technology. Notably, the use of lead carbonate powders, rather than lead oxide, significantly improves the curing characteristics and printability of ceramic slurry. Additionally, lanthanum oxide powders are introduced as dopants to enhance the electrical properties of PZT ceramics. The printed piezoceramics exhibit excellent piezoelectric and dielectric performance under optimal La3+ content, coupled with superior transduction coefficient, electromechanical coupling factor and output voltages and currents. Our findings suggest a groundbreaking approach for fabricating piezoceramics with high energy-harvesting performance and complicated designed structure via digital light processing.

Direct 3D printing of triple-responsive nanocomposite hydrogel microneedles for controllable drug delivery

Hydrogel microneedle patches have emerged as promising platforms for painless, minimally invasive, safe, and portable transdermal drug administration. However, the conventional mold-based fabrication processes and inherent single-functionality of such microneedles present significant hurdles to broader implementation. Herein, we have developed a novel approach utilizing a precursor solution of robust nanocomposite hydrogels to formulate photo-printable inks suitable for the direct 3D printing of high-precision, triple-responsive hydrogel microneedle patches through digital light processing (DLP) technology. The ink formulation comprises four functionally diverse monomers including 2-(dimethylamino)ethyl methacrylate, N-isopropylacrylamide, acrylic acid, and acrylamide, which were crosslinked by aluminum hydroxide nanoparticles (AH NPs) acting as both reinforcing agents and crosslinking centers. This results in the formation of a nanocomposite hydrogel characterized by exceptional mechanical strength, an essential attribute for the 3D printing of hydrogel microneeedle patches. Furthermore, this innovative 3D printing strategy facilitates facile customization of microneedle geometry and patch dimensions. As a proof-of-concept, we employed the fabricated hydrogel microneedles for transdermal delivery of bovine serum albumin (BSA). Importantly, these hydrogel microneedles displayed no cytotoxic effects and exhibited triple sensitivity to pH, temperature and glucose levels, thereby enabling more precise on-demand drug delivery. This study provides a universal method for the rapid fabrication of hydrogel microneedles with smart responsiveness for transdermal drug delivery applications.

Digital light processing printing of porous ceramics using interparticle photo-cross-linkable Pickering emulsions

Digital light processing (DLP) printing using photo-curable Pickering emulsion is a promising route to fabricate porous ceramics having on-demand structures. However, the long duration for debinding/sintering due to the large organic contents remained in the photo-cured bodies and the insufficient long-term stability of the emulsions needs to be solved toward efficient manufacturing. Herein, a new interparticle photo-cross-linkable Pickering emulsion having improved stability, which can be photo-cured using reduced amounts of monomers, were designed for the rapid production of porous ceramics using DLP printing. The Pickering emulsion was obtained by mixing isopropyl myristate into a dimethyl sulfoxide (DMSO) aqueous suspension of SiO2 particles with pre-dissolved polyethylene glycol diacrylate (PEGDA) and a photo-radical initiator. Further, functionalized polyethyleneimine (PEI) was designed to ensure the dispersion of SiO2 particles and formation of a Pickering emulsion. The photo-irradiation of the designed Pickering emulsion resulted in the successful photo-curing by the radical polymerization of PEGDA, followed by a Michael addition reaction between the reactive amine of PEI and acryloyl groups of PEGDA. The improved stability of the emulsion over time and reduced amounts of monomer facilitated the application of the designed emulsion to DLP printing, followed by a rapid firing process without any structural collapse.

Itaconic acid-based 3D printed nanocomposites: an in-depth study on the effect of nanoinclusions on the physicochemical properties and the printability of formulations based on polyester itaconates

The demand for novel bio-based materials in UV-curing additive manufacturing has surged due to increasing environmental concerns and a growing emphasis on sustainable practices in the manufacturing industry. However, at the moment, their thermomechanical performance is not equal to that of their fossil-based counterparts and this impedes the acceptance of these materials within the industrial community. Therefore, in this study, a series of nanocomposite polyesters based on itaconic acid was synthesized for the first time with in-situ polymerization, in an attempt to leverage the unique properties of nanofillers and improve the overall performance of the material. A variety of reinforcing agents were utilized, namely cellulose nanocrystals (CNC), montmorillonite (MMT), graphene nanoplatelets (GNP) and titanium dioxide (TiO2), to understand the effect of each filler on the physicochemical properties of the polyester. Formulations of these polyesters were then prepared and processed on a digital light processing (DLP) 3D printer to prepare test specimens. Extensive thermomechanical characterization showed that the interference of the fillers with the UV curing process was the main parameter determining the mechanical performance of the 3D printed materials.

Vat photopolymerization of biomimetic bone scaffolds based on Mg, Sr, Zn-substituted hydroxyapatite: Effect of sintering temperature

In response to the urgent demand for innovative bone regeneration solutions, the focus of this study is to develop and characterize Mg, Sr, Zn-substituted calcium phosphate scaffolds that replicate the trabecular architecture of cancellous bone. Ion substitution represents a promising approach to improve the biological effectiveness of calcium phosphates and composite materials used in bone tissue engineering applications. Porous scaffolds mimicking the natural bone structure were additively manufactured from the photosensitive ceramic suspensions for vat photopolymerization using digital light processing. The impact of the selected trace elements (0, 1 and 5 mol.% substitution) and the sintering temperature (900, 1000, 1100, 1200, and 1300 °C) was investigated in relation to the obtained crystalline phase content, microstructure, elemental distribution, thermal stability, and mechanical properties. After sintering, in addition to hydroxyapatite, β-tricalcium phosphate was detected as a result of the added trace elements in the calcium-deficient hydroxyapatite used as a starting powder. The obtained scaffolds exhibited uniform distribution of the trace elements, and they feature 3D-designed porosity predominantly ranged from 10 to 900 μm in diameter, with an average pore size of 546.25 ± 10.95 μm. The total porosity of scaffolds was 76.24 ± 1.32 vol.% and an average wall thickness of 217.03 ± 8.98 μm, closely resembling the morphology of cancellous bone tissue. The mechanical properties of the scaffolds sintered at 1100°C, 1200°C, and 1300°C were in line with those typically observed in trabecular bone. The study demonstrates the feasibility of using custom made bioactive hydroxyapatite powders together with vat photopolymerization to design the porosity and properties of the bone scaffolds on demand, based on the requirements of individual bone defects.

Aqueous zinc ion batteries (AZIBs) are an increasingly popular high-safety and eco-friendly energy storage solution. However, the development of high-performance zinc (Zn) anodes remains a formidable challenge, primarily due to dendrite formation and poor reversibility. To address these challenges, this study harnesses the potential of digital light process (DLP) 3D printing technology to fabricate reduced graphite oxide-based 3D gyroid structure (3DP-rGG) as zinc anode frameworks for aqueous zinc batteries. The 3D-printed structure effectively regulates local current density distribution, offering ample nucleation sites and free space for inducing uniform zinc deposition and accommodating diminutive zinc nodules. Consequently, the 3D-printed graphite framework demonstrates remarkable reversibility in zinc plating and stripping processes, resulting in commendable coulombic efficiency and low voltage hysteresis. The full battery with a 3D-printed anode structure, incorporating a polyaniline-intercalated vanadium oxide cathode (PVO), exhibits high specific capacity and superior long-term cycling stability. Remarkably, the robust 3DP-rGG structure can be reused over ten times without any discernible impact on its electrochemical performance, thereby underscoring the potential of this controllable and efficient fabrication of 3D graphite current collectors as a promising solution to develop reusable 3D frameworks for high-performance metal batteries.

AbstractThe development of multifunctional organic materials represents a vibrant area of research, with applications spanning from biosensing to drug delivery. This study shows the development of a multifunctional bioelectronic device suitable for prolonged temperature monitoring and drug delivery applications. The device relies on a conducting and thermo‐responsive hydrogel made of poly(3,4‐ethylenedioxythiophene) doped with poly(styrene sulfonate) (PEDOT:PSS) and poly(N‐isopropylacrylamide) (PNIPAM). This multifunctional hydrogel is 4D printable by Digital Light Processing (DLP) method and exhibits optimal biocompatibility. The hydrogel features a low critical solution temperature (LCST) ≈35 °C, above which its resistance changes dramatically due to the shrinkage it undergoes with temperature. The integration of PNIPAM/PEDOT hydrogel into an organic electrochemical transistor (OECT) as the gate electrode allows to generate a miniaturized bioelectronic device with a reversible response to temperature variations between 25 to 45 °C, along with high sensitivity of 0.05 °C−1. Furthermore, the PNIPAM/PEDOT hydrogel demonstrates its utility in drug delivery, achieving an Insulin‐FITC release rate of 82 ± 4% at 37 °C, mimicking human body conditions. The hydrogel's functionality to store and release the insulin does not compromise its thermo‐responsivity and the overall performance of the OECT. This multifunctional OECT opens new avenues for the development of customizable and personalized sensing and drug‐delivery systems.

Assessment of the Development Performance of Additive Manufacturing VPP Parts Using Digital Light Processing (DLP) and Liquid Crystal Display (LCD) Technologies

Non-metallic additive manufacturing technology has seen a substantial improvement in the precision of the parts it produces. Its capability to achieve complex geometries and very small dimensions makes it suitable for integration into strategic industrial sectors, such as aeronautics and medicine. Among additive manufacturing technologies, resin development processes demonstrate enhanced precision when compared to other methods, like filament printing. This study conducts a comparative analysis between digital light processing (DLP) and liquid crystal display (LCD) photopolymerization processes to assess the performance of the technologies and how process parameters affect the accuracy of the resulting parts. The research evaluates the impact of the discretization process used during the digital model export, determining the optimal mesh size and then analyzing the geometric deviations that occur by altering various operating parameters of the process. Statistical methods will be employed to identify the most significant parameters in the manufacturing process. Among other aspects, the precision of manufacturing technologies regarding the movement axis has also been evaluated. Regarding the minimum size of the features that can be fabricated, DLP technology has surpassed LCD technology, successfully producing features as small as 200 µm, compared to 500 µm for LCD technology.

Enhancing the 3D printing fidelity of vat photopolymerization with machine learning-driven boundary prediction

Like many pixel-based additive manufacturing (AM) techniques, digital light processing (DLP) based vat photopolymerization faces the challenge that the square pixel based processing strategy can lead to zigzag edges especially when feature sizes come close to single-pixel levels. Introducing greyscale pixels has been a strategy to smoothen such edges, but it is a challenging task to understand which of the many permutations of projected pixels would give the optimal 3D printing performance. To address this challenge, a novel data acquisition strategy based on machine learning (ML) principles is proposed, and a training routine is implemented to reproduce the smallest shape of an intended 3D printed object. Through this approach, a chessboard patterning strategy is developed along with an automated data refining and augmentation workflow, demonstrating its efficiency and effectiveness by reducing the deviation by around 30%.

The objective of the present study was to enhance the bioavailability of cannabidiol (CBD) using 3D Digital Light Processing (DLP)-printed microneedle (MN) transdermal drug delivery system. CBD MN patch was fabricated and optimized using 3D DLP printing using CBD (8% w/v), Lithium phenyl-2,4,6-trimethylbenzoylphosphinate (LAP) (0.49% w/v), distilled water (20% w/v), and poly (ethylene glycol) dimethacrylate 550 (PEGDAMA 550) (up to 100% w/v). CBD MNs were characterized for their morphology, mechanical strength, in vitro release study, ex vivo permeation study, and in vivo pharmacokinetic (PK) profile. Microscopic images showed that sharp CBD MNs with a height of ~800 μm, base diameter of ~250 μm, and tip with a radius of curvature (RoC) of ~15 μm were successfully printed using optimized printing parameters. Mechanical strength studies showed no significant deformation in the morphology of CBD MNs even after applying 0.5N/needle force. Ex vivo permeation study showed significant (P < .0001) permeation of CBD in the receiving media as compared to CBD patch (control). In vivo PK study showed significantly (P < .05) enhanced bioavailability in the case of CBD MN patch as compared to CBD subcutaneous inj. (control). Overall, systemic absorption of CBD was significantly enhanced using 3D-printed MN drug delivery system.

Improving the Performance of Photoactive Terpene-Based Resin Formulations for Light-Based Additive Manufacturing.

Photocurable liquid formulations have been a key research focus for the preparation of mechanically robust and thermally stable networks. However, the development of renewable resins to replace petroleum-based commodities presents a great challenge in the field. From this perspective, we disclose the design of photoactive resins based on terpenes and itaconic acid, both potentially naturally sourced, to prepare photosets with adjustable thermomechanical properties. Biobased perillyl itaconate (PerIt) was synthesized from renewable perillyl alcohol and itaconic anhydride via a scalable solvent-free method. Photoirradiation of PerIt in the presence of a multiarm thiol and photoinitiator led to the formation of networks over a range of compositions. Addition of nonmodified terpenes (perillyl alcohol, linalool, or limonene) as reactive diluents allowed for more facile preparation of photocured networks. Photosets within a wide range of properties were accessed, and these could be adjusted by varying diluent type and thiol stoichiometry. The resins showed rapid photocuring kinetics and the ability to form either brittle or elastic materials, with Young's modulus and strain at break ranging from 3.6 to 358 MPa and 15 to 367%, respectively, depending on the chemical composition of the resin. Glass transition temperatures (Tg) were influenced by thioether content, with temperatures ranging from 5 to 43 °C, and all photosets displayed good thermal resistance with Td,5% > 190 °C. Selected formulations containing PerIt and limonene demonstrated suitability for additive manufacturing technologies and high-resolution objects were printed via digital light processing (DLP). Overall, this work presents a simple and straightforward route to prepare renewable resins for rapid prototyping applications.
