Purpose This paper aims to present a method of color three-dimensional (3D) printing based on color adherence. Design/methodology/approach First, experiments of the color effects of 3D printings using different carriers and different printing methods were performed. Second, the color of a specific point could be calculated through a theory of dimension-reducing, and the color distribution of 3D model was transformed from 3D to 1D color line corresponding with 3D print sequence. At last, the color lines, which were printed on a PE film by silk-screen printing, was carried by a filament and then printed through a fused deposition modeling 3D printer. Findings The printing ink and PE film are suitable as the pigment and carrier under this investigation, respectively. Based on an idea of reducing dimension, the method of 3D color printing through adhering color to a filament is realized. The color saturation of the sample was relatively high through the method. Research limitations/implications It is hard to avoid that there may be some residual color in the nozzle through this method, and the purity of following color will be affected. As a result, continuous improvements should be made to perfect the method. Practical implications An approach of 3D color printing is described in detail, and what kind of model is more applicable is discussed particularly. Originality/value This approach is implemented to print color 3D objects with just one nozzle by means of color adherence. That is, printing the 3D objects using the filament is carried out with 1D color line, which is printed by a traditional printing method.

Microstructure plays an important role in improving the performance of flexible sensors. Changing the shape of the dielectric layer microstructure is an effective countermeasure to promote the sensitivity of capacitive sensors. Nevertheless, traditional microstructure fabrication methods have high manufacturing costs, cumbersome manufacturing processes, and single structure manufacturing, which restrict the development of flexible sensors. In this work, electro-hydro-dynamic (EHD) printing method and aerosol jet (AJ) printing method were applied to fabricate 3D microstructures, in a manner of printing the same pattern in multiple layers. The height and morphology of 3D microstructures, under different printing parameters, were compared by changing the number of printing layers and printing speed. Additionally, the printing effects of the two printing methods were compared. The results demonstrated that various shapes and highly controllable 3D microstructures could be fabricated by both methods. The EHD printing method had higher manufacturing precision, whereas the AJ printing method had higher stacking efficiency. The height and morphology of 3D microstructures could be effectively controlled by changing the number of printed layers and the printing speed of the microstructures. It is indicated that the EHD printing method and the AJ printing method both have great potential in the fabrication of 3D microstructures and that both methods had their own advantages.

We propose a method for digital printing which is novel and efficient. Digital printing is a technical breakthrough in the field of traditional printing and dyeing industry, which is also an effective solution to solve the three high problem, namely, high energy consumption, high noise, high pollution, in the traditional printing and dyeing industry. However, the widely used methods in printing and dyeing system have some deficiencies, such as the low performance of the PC processor and the limitation of transferring data by parallel interface. The proposed method takes advantage of multi-core processor, DMA and RAID technology. Multi-core processor can speed up the processing of the print command and the print images, while DMA technology can minimize the intervention of the CPU to input/output operations which makes the CPU more effective to process the images. Furthermore, the use of RAID technology can improve the access speed of the hard disk which leading to the efficiency improvement of the entire computer system. As we can see that the combination of those three technologies can greatly improve the efficiency of digital printing machine, thus speeding up the popularity of digital printing.

Bioprinting, defined as depositing cells, extracellular matrices and other biologically relevant materials in user-defined patterns to build tissue constructs de novo or to build upon pre-fabricated scaffolds, is among one of the most promising techniques in tissue engineering. Among the various technologies used for Bioprinting, pressure driven systems are most conducive to preserving cell viability. Herein, we explore the abilities of a novel bioprinter - Digilab, Inc.'s prototype cell printer. The prototype cell printer (Digilab Inc., Holliston, MA) is an automated liquid handling device capable of delivering cell suspension in user-defined patterns onto standard cell culture substrates or custom-designed scaffolds. In this work, the feasibility of using the cell printer to deliver cell suspensions to biological sutures was explored. Cell therapy using stem cells of various types shows promise to aid healing and regeneration in various ailments, including heart failure. Recent evidence suggests that delivering bone-marrow derived mesenchymal stem cells to the infarcted heart reduces infarct size and improves ventricular performance. Current cell delivery systems, however, have critical limitations such as inefficient cell retention, poor survival, and lack of targeted localization. Our laboratories have developed a method to produce discrete fibrin microthreads that can be bundled to form a suture and attached to a needle. These sutures can then be seeded with bone-marrow derived mesenchymal stem cells to deliver these cells to a precise location within the heart wall, both in terms of depth and surface localization. The efficiency of the process of seeding cells onto fibrin thread bundles (sutures) has previously been shown to be 11.8 ± 3.9 %, suggesting that 88% of the cells in suspension are not used. Considering that the proposed cell-therapy model for treatment of myocardial infarction contemplates use of autologous bone-marrow derived stem cells, an improvement in the efficiency of seeding cells onto the fibrin sutures is highly desirable. The feasibility of using Digilab's prototype cell printer to deliver concentrated cell suspension containing human mesenchymal stem cells (hMSCs) directly onto a fibrin thread bundle was explored in this work, in order to determine if this technology could be adapted to seed cells onto such biological sutures. First the effect of the printing process on the viability of hMSCs was assessed by comparing to cells dispensed manually using a hand-held pipette. The viability of hMSCs 24 hours post-dispensing using the cell printer was found to be 90.9 ± 4.0 % and by manual pipetting was 90.6 ± 8.2 % (p = ns). Thereafter a special bioreactor assembly composed of sterilizable Delrin plastic and stainless steel pins was designed to mount fibrin thread bundles onto the deck of the cell printer, to deliver a suspension containing hMSCs on the bundles. Highly targeted delivery of cell suspension directly onto fibrin thread bundles (average diameter 310 µm) was achieved with the bundle suspended in mid-air horizontally parallel to the printer's deck mounted on the bioreactor assembly. To compare seeding efficiency, fibrin thread bundles were simultaneously seeded with hMSCs using either the cell printer or the current method (tube-rotator method) and incubated for 24 hours. Seeded thread bundles were visualized using confocal microscopy and the number of cells per unit length of the bundle was determined for each group. The average seeding efficiency with the tube rotator method was 7.0 ± 0.03 % while the cell printer was 3.46 ± 2.24% (p = ns). In conclusion, the cell printer was found to handle cells as gently as manual pipetting, preserve their viability, with the added abilities to dispense cells in user-defined patterns in an automated manner. With further development, such as localized temperature, gas and humidity control on the cell printer's deck to aid cell survival, the seeding efficiency is likely to improve. The feasibility of using this automated liquid handling technology to deliver cells to biological scaffolds in specified patterns to develop vehicles for cell therapy was shown in this study. Seeding other cell types on other scaffolds along with selectively loading them with growth factors or multiple cell types can also be considered. In sum, the cell printer shows considerable potential to develop novel vehicles for cell therapy. It empowers researchers with a supervision-free, gentle, patterned cell dispensing technique while preserving cell viability and a sterile environment. Looking forward, de novo biofabrication of tissue replicates on a small scale using the cell printer to dispense cells, extracellular matrices, and growth factors in different combinations is a very realistic possibility.

Traditional approaches to constructing 3D structural electronics with conductive and dielectric materials include ink-jet printed, silver-bearing ink and fine copper wire meshes. One approach combines stereo-lithographic 3D-printed photo-polymers with direct-printed silver-bearing conductive inks. Results have shown 3D conductive structures with conductivities in the range 2x10⁶ to 1x10⁷ S/m using annealing temperatures ranging from 110°C to 150°C for 10 to 15 minutes. However, the stereo-lithographic approach suffers from the high cost of the printer and structural deformation during annealing. This paper presents a new method for 3d printing high conductivity metal alloys using consumer-grade 3D printer. The design and construction of the necessary modification will be presented in addition to the new 3D design process. The method yields metal structures with expected conductivities exceeding 2.6x10⁶ S/m. The process is performed without an annealing step, so the polymeric structural material is not exposed to high temperatures for any prolonged time. A UHF ISM band antenna is constructed for an RFID application using this method, the antenna performance is measured, and the results are compared simulations in Ansys HFSS. This new method can reduce total cost, and several low melting-point alloys could raise the conductivity.

Traditional microbiological experimental methods generally reveal population-wide statistics and are not capable of revealing variations between individual cells. In an effort to address this, a cheap, quick and easy means of producing micro-arrays with live bacteria immobilized on the array's coordinates has been developed. To achieve this, microcontact printing (µCP) was used to print circular PD ``islands'' onto a surface coated with either PEG or PVA. The bacteria, <i>Pseudomonas putida</i> KT2440 were successfully immobilized on approximately 97% of the printed islands, depending on island diameter. A LIVE/DEAD® <i>Bac</i>Light™ assay revealed that over 99% of the immobilized bacteria survive the immobilization on the array. Qualitative analysis suggests the bacteria survive for hours after immobilization, provided nutrients are available. The developed method may, by revising the stamp design and/or choice of elastomer, likely be optimized to immobilize only one bacterium per array coordinate.

The two projects covered by this thesis represent advancements in the field of biofabrication. The first project was a proof-of-principle study focused on the development of a new polymer ink for 3D-printing. Scaffold structures were printed with a hydrophilic polymer and characterized to determine optimum printing parameters. Crosslinking strategies to create hydrogels with properties similar to human tissue were also explored. The second project was focused towards developing adipose grafts for soft tissue defects. Microfibre scaffolds were designed and 3D-printed with pores suitably sized for seeding with aggregates of human stem cells, and differentiated into fat tissue under in vitro conditions.

The goal of this project is to apply 3D printing and moulding (3DPM) methods for the fabrication of a miniature magnetic actuator for optical image stabilization (OIS) applications. Polydimethylsiloxane (PDMS) and strontium ferrite (SrFe) nano powder were used as the main structural material. Young’s modulus and the magnetization of the material with SrFe-doping ratios ranging from 20% to 60% by weight were characterized. The actuator, consisting of four coils, an actuating plate, and a base supporter was assembled and tested with a Laser Doppler Velocimetry (LDV) system. A tilting angle of 0.6º was achieved with the application of 500 mA (50 turns/9 mm long coils). A Taguchi’s orthogonal experimental design was used in the finite element analysis (FEA) simulation to examine the effect of dimension variations on the eigenfrequencies. Frequency response of the actuator was characterized and the experimental results matched with the simulation results between 1 and 450 Hz showing less than 5% errors. A series of replica experiments were also performed and analyzed.

Dans le domaine de l'électronique souple, les substrats flexibles à base de polymères sont de plus en plus utilisés. Si dans les prochaines années, les structures de propagation mises en œuvre sur ce type de substrat véhiculent une puissance, alors la connaissance de la conductivité thermique de ces matériaux est essentielle. Dans ce travail, nous mesurons la conductivité thermique de matériaux de type polymère en utilisant la méthode 3 omégas. Des mesures ont été effectuées sur du polydiméthylsiloxane (PDMS). Un procédé technologique particulier est utilisé pour la fabrication des échantillons de PDMS. De ce fait, les conducteurs métalliques sont encapsulés dans le polymère et non en surface de ce dernier. Mais cela est sans conséquence sur les valeurs de conductivité thermique mesurées. Les procédés photolithographiques utilisés traditionnellement pour réaliser les lignes métalliques sont coûteux et longs. Par conséquent, nous proposons pour ce type de matériaux une méthode alternative pour la réalisation des lignes conductrices grâce à la technologie d'impression par jet d'encre. Les conductivités thermiques du polyimide et polyétheréthercétone ont été mesurées en utilisant la méthode 3omega combinée à la technologie d'impression par jet d'encre.Des simulations numériques basées sur la méthode des éléments finis ont été développées au cours de la thèse. Les mesures expérimentales obtenues sont comparées aux résultats obtenus par une solution analytique et par notre modélisation numérique.Ainsi durant cette thèse nous montrons avec succès la possibilité d'utiliser la technologie d'impression jet d'encre pour mesurer la conductivité thermique d'un substrat souple
The characterization of polymers is gaining a great attention as they are one of the main constituents of future flexible or organic electronics. Given the fact that thermal management is an important issue in the frame work of flexible electronics, the knowledge of the thermal conductivity of polymer materials is needed. In this work, we propose the measurement of polymer material thermal conductivity using the three omega method. This method requires heating a metallic line conductor placed on the surface of the material under test by an alternating current source. The first measurements were done on polydimethyl siloxane (PDMS) polymer material for which a special procedure that consists in embedding the metallic line conductors near the surface has been applied.In addition to the well-known limitations of photolithography process which are the cost and the process duration, a particular concern lies in the fabrication of the metallic conductors by such process which might be destructive in case of polymer materials. Consequently, we propose an alternative method for this kind of materials based on inkjet printing technology. The thermal conductivities of polyimide and polyetherether ketone have been successfully measured using the three omega method combined with inkjet printing technology for sample preparation. Numerical simulations using finite element method (FEM) are also performed. Finally, experimental measurements are compared to Cahill’s analytical solution and FEM modelling. The overall results demonstrate that the inkjet printing technology is a good candidate for the characterization of flexible materials in terms of thermal conductivity

Abstract3D concrete printing (3DCP) has been successfully and widely applied in the fields of civil structure, infrastructure, architectural decoration etc.,due to its unique advantages of automation and flexibility, and has shown great potential for development. One of the key steps in the execution of 3DCP is the tool-path planning process. However, 3DCP typically utilize the flowable composite materials which changes with time, and it is easy to induce interface joints or filling defects due to uneven path distribution when constructing the irregular-shaped construction. To solve the problem of printing path planning in 3DCP, this paper proposes tool-path planning based on mapping method, which integrates the rheology and necessary continuity of concrete materials into the printing process parameters, improves the mutual adaptability of printing process and material characteristics, improves the continuity of printing, the compactness of filling, and then ensures the stability and durability of printing structure.

AbstractExcessive gamma-rays will be emitted when a nuclear power plant is under the refueling overhaul, leading to a certain number of hotspots. To meet the shielding requirements of these hotspots of complex components, a nylon-tungsten shielding composite material was developed by laser selective sintering 3D printing technology. The effects to shielding performance of 3D printing shielding materials were emphatically studied for two preparation processes (including mechanical mixing method and coating method) of 3D printing composite powders. Experimental results show that the nylon-tungsten shielding composite material with tungsten content of 70–85% was obtained by 3D printing technology, which realizes the manufacture of mold-free customized and bonded shielding materials. The shielding material prepared by 3D printing technology by coating method is better than that by mechanical mixing method in shielding performance. When the mass ratio of tungsten powders is 80%, the linear attenuation coefficient can reach 0.32, which is the best formula of the composite material and can be used for shielding of complex components. All these results lay a theoretical foundation for the engineering application of 3D printing shielding materials.

Abstract In recent years, flexible electronic devices such as printed electronics are gathering attention. To make flexible connect between one circuit device and another circuit device, interposer is necessary. However, most of conventional interposers are not flexible, because there are made of silicon or glass substrate. To solve this problem, we have been developed fabrication process of flexible interposer. Master mold was fabricated by photolithography process. First, SU-8 resist was coated on silicon substrate with 5μm thickness. Then, photolithography process was carried out to SU-8 resist. After development, pillar shape master molds with diameters of 10 or 20 μm were obtained. After release coating of master molds, hole patterns for vias were transferred by UV nanoimprint lithography. The obtained hole patterns were diameter of 10 μm or 20 μm, and pitch of 21.0 μm and 40.1 μm, respectively. Next, these holes were filled with silver ink by roll press method. Then, sintering process was carried out to evaporate of solvent of silver ink. After that, flexible interposer was obtained. As a result, we have been succeeded in filling the holes array with silver ink. Obtained interposer vias, which were silver region, were 8.2 μm diameter and 3.3 μm height, or 20.3 μm diameter and 5.3 μm height for 10 mm square size.

A glass substrate has many advantages as an optical disk substrate. On a glass substrate, pits and grooves can be formed directly by a laser cutting machine and reactive etching.1) A highly reliable glass substrate can be obtained by this method, however, there is a problem of low productivity. It takes more than 30 minutes for patterning by laser cutting machine. This paper describes a contact printing method which can improve the productivity of conventional patterning, and discusses the signal performance of magneto-optical disks using a substrate prepared by the contact printing method.

3D printing, also called additive manufacturing, represents a range of technologies that create 3D objects through a layer-by-layer deposition process using digital image files. 3D printing evolved over the past four decades from a prototyping tool to a manufacturing method in its own right in a number of industries and several additive manufacturing processes have matured into robust production technologies for highly customised and bespoke products when produced in small numbers. However, 3D printing technologies at their current stage of evolution are usually not considered commercially viable for mass production applications.

This Dredging Operations Environmental Research (DOER) technical note disseminates novel methods to monitor and reduce contaminant mobility and bioavailability in water, sediments, and soils. These method advancements are enabled by additive manufacturing (i.e., three-dimensional [3D] printing) to deploy and retrieve materials that adsorb contaminants that are traditionally applied as unbound powders. Examples of sorbents added as amendments for remediation of contaminated sediments include activated carbon, biochar, biopolymers, zeolite, and sand caps. Figure 1 provides examples of sorbent and photocatalytic particles successfully compounded and 3D printed using polylactic acid as a binder. Additional adsorptive materials may be applicable and photocatalytic materials (Friedmann et al. 2019) may be applied to degrade contaminants of concern into less hazardous forms. This technical note further describes opportunities for U.S. Army Corps of Engineers (USACE) project managers and the water and sediment resource management community to apply 3D printing of polymers containing adsorptive filler materials as a prototyping tool and as an on-site, on-demand manufacturing capability to remediate and monitor contaminants in the environment. This research was funded by DOER project 19-13, titled “3D Printed Design for Remediation and Monitoring of Dredged Material.”

This paper presents a finite-deformation model for extrusion-based layered printing with cementitious materials. The evolution of mechanical properties as the printed material cures and stiffens results in nonphysical reduction in the magnitude of elastic strains when standard constitutive models are employed. This elastic recovery of the printing induced deformation contradicts the experimentally observed behavior of the printed cementitious materials that harden at a nearly-frozen deformed state. A thermodynamically motivated constraint on the evolution of elastic strains is imposed on the constitutive model to remedy the nonphysical bounce-back effect. An algorithm that is based on a strain-projection technique for the elastic part of deformation is developed that complements the inelastic response given by the Drucker–Prager model. It is then embedded in a finite strain finite element framework for the modeling and simulation of cure hardening and inelastic response of the early age cementitious materials. A ghost mesh method is proposed for continuous layer-wise printing of the material without the need for intermittent mesh generation technique or adaptive remeshing methods. The model is validated via comparison with experimental data and representative test cases are presented that investigate the mathematical and computational attributes of the proposed model.

Digital Light Processing (DLP) 3D printing allows for the creation of parts with advanced engineering materials and geometries difficult to produce through conventional manufacturing techniques. Photosensitive resin monomers are activated with a UV-producing LCD screen to polymerize, layer by layer, forming the desired part. With the right mixture of photosensitive resin and advanced engineering powder material, useful engineering-grade parts can be produced. The Bison 1000 is a research-grade DLP printer that permits the user to change many parameters, in order to discover an optimal method for producing 3D parts of any material of interest. In this presentation, the process parameter optimization and their influence on the 3D printed parts through DLP technique will be discussed. The presentation is focused on developing 3D printable slurry, printing of complex ceramic lattice structures, as well as post heat treatment of these DLP-produced parts.

The article desribes the main features of the publishing activity of the Ivan Franko National University of Lviv from the end of the 1990s and in the first two decades of the 21st century. The aim of the author was to show this activity with the help of stages of formation of the Publishing Centre at the University. For this purpose, he used historical method, the methods of analysis, synthesis, content analysis etc. One of the important landmarks of the end of the 20th century in the publishing activity of the Ivan Franko National University of Lviv which has its traditions in the past was the foundation of the mentioned Publishing Centre on the basis of Editing and Publishing Department, Machine Offset and Polygraphic Laboratories. This process was favoured by the administration of the University which supported the transfer of printing base to another building of the University. Professionals with respective qualification level and experience in the sphere of publishing and printing were gathered there. Another stage of the development of the Publishing Centre of the Ivan Franko National University of Lviv was the creation in 2006 of the Publishing Board within the University which became a generator of ideas on the development of scientific book publishing and actively cooperated with printing enterprises of Ukraine (the author of the article was a member of this board). The administration of the Ivan Franko National University of Lviv provided a substantial financial support for publication of educational and scientific literature of different genres and on different topics for educational needs both of the University itself and Ukrainian educational sphere in general. As a result of active publishing activity, the Publishing Centre of the Ivan Franko National University of Lviv since 1996 has published more than 4.5 million copies of publications whose authors are members of the academic community of the University. Among the significant publications of the Publication Centre of the last two decades the article notes Ivan Franko (10 volumes, authors – R. Horak and Ya. Hnativ), Encyclopedia. The Ivan Franko National University of Lviv (2 volumes), Social Geography (2 books, author – Prof. O. Shabliy) and others. The results of the activities of the Publication Centre of the Ivan Franko National University of Lviv were demonstrated during participation at Book Forums and other events in the publication and printing sphere. This article permits researchers in Humanities to analyze and evaluate the achievements and at the same time problems of the scientific publication activity of the Ivan Franko National University of Lviv.

Particles deposited on mucosa or penetrating into lower airway are two exposure routes. Quantifying administered dose of these two routes gives us idea for future advanced individual protection. Here, we report an in-vitro method to assess the administered doses of eyes, lips, and lower airway. A CT scanning and 3D-printing based human replica is developed, and exposed in front of the 0.6-5μm monodispersed fluorescent particles. At small size particles (<2.5 μm), the administered dose intensity of penetrating into lower airway inhalation (~59.41×10-2 g/g, 0.6μm) is higher than that of eyes and lips (~5.97×10-2 g/g, 0.6μm). Conversely, the administered dose intensity of lower airway inhalation (~9.39×10-2 g/g) becomes higher than that of eyes and lips (~6.24×10-2 ) g/g at 5.0μm particles. This work provides us an effective and economical way to assess exposure risks of particulate contaminants.

The impacts of Harmful Algal Blooms (HAB), often caused by cyanobacteria (Figure 1), on water resources are increasing. Innovative solutions for treatment of HABs and their associated toxins are needed to mitigate these impacts and decrease risks without introducing persistent legacy contaminants that cause collateral ecosystem impacts. This technical note (TN) identifies novel opportunities enabled by Additive Manufacturing (AM), or 3D printing, to produce high surface area advanced material composites to rapidly prototype sustainable environmental solutions for aquatic nuisance species control. This innovative research explores deployment of 3D-printable polymer composite structures containing nano-scale photocatalysts for targeted open water treatment of HABs that are customizable to the site-of-concern and also retrievable, reusable, and sustainable. The approach developed to control cyanobacteria HAB events has the potential to augment or replace broadcast, non-specific chemical controls that otherwise put non-target species and ecological resources at long-term risk. It can also augment existing UV-treatment HAB treatment control measures. The expected research outcome is a novel, effective, and sustainable HAB management tool for the US Army Corps of Engineers (USACE) and resource managers to deploy in their HAB rapid response programs. The research will provide a framework for scale-up into other manufacturing methods (e.g., injection molding) to produce the devices in bulk (quickly and efficiently). Research for this project title “Mitigation of Harmful Algal Bloom Toxins using 3D Printed Photocatalytic Materials (FY21-23)” was sponsored by the US Army Engineer Research Development Center’s (ERDC) Aquatic Nuisance Species Research Program (ANSRP).
