Abstract:

Over the last few decades, advanced manufacturing and additive printing technologies have made incredible inroads into the fields of engineering, transportation, and healthcare. Among additive manufacturing technologies, 3D printing is gradually emerging as a powerful technique owing to a combination of attractive features, such as fast prototyping, fabrication of complex designs/structures, minimization of waste generation, and easy mass customization. Of late, 4D printing has also been initiated, which is the sophisticated version of the 3D printing. It has an extra advantageous feature: retaining shape memory and being able to provide instructions to the printed parts on how to move or adapt under some environmental conditions, such as, water, wind, light, temperature, or other environmental stimuli. This advanced printing utilizes the response of smart manufactured materials, which offer the capability of changing shapes postproduction over application of any forms of energy. The potential application of 4D printing in the biomedical field is huge. Here, the technology could be applied to tissue engineering, medicine, and configuration of smart biomedical devices. Various characteristics of next generation additive printings, namely 3D and 4D printings, and their use in enhancing the manufacturing domain, their development, and some of the applications have been discussed. Special materials with piezoelectric properties and shape-changing characteristics have also been discussed in comparison with conventional material options for additive printing.

Abstract:

Abstract The rheological properties of silver inks are analyzed, and the printing results are presented based on the inks and roll-to-roll (R2R) printing speed. The shear viscosity, shear modulus, and extensional viscosity of the inks are measured using rotational and extensional rheometers. The inks exhibit the shear thinning power law fluids because the concentration of dispersed nanoparticles in the solvent is sufficiently low, which minimizes elasticity. After the inks are printed on a flexible substrate through gravure printing, the optical images, surface profiles, and electric resistances of the printed pattern are obtained. The width and height of the printed pattern change depending on the ink viscosity, whereas the printing speed does not significantly affect the widening. The drag-out tail is reduced at high ink viscosities and fast printing speeds, thereby improving the printed pattern quality in the R2R process. Based on the results obtained, we suggest ink and printing conditions that result in high printing quality for complicated printings, such as overlay printing registration accuracy, which imposes pattern widening and drag-out tails in printed patterns.

Abstract:

Abstract In order to optimize the tool path of 3D printing such that the efficiency is improved, by summerizing the pros and cons of existing methods, we proposed a noval tool path optimization algorithm for layered 3D printings based on solving the Traveling Salesman Problem. Our algorithm first adjusts the major printing direction using Principal Components Analysis, and then applies the greedy strategy and generates multiple printing paths by interleavingly appending the filling segments and contour segments along the major printing direction. Thereafter, by considering the multiple printing paths as “cities”, and elaborately defining the distances between them, we successfully model the problem of minimizing the flying distances as a kind of Traveling Salesman Problem. Af-ter converting the accurate solution of TSP to our problem, we are able to get the global optimized tool path with the given multiple printing paths. Experiments demonstrate that the proposed algorithm not only miminizes the flying distances, but also reduces the switches between printing status and flying status, and boosts the percentage of long segments in the whole tool path as well, thus the printing efficiency is significently imporved without sac-rifying the printing quality.

Abstract:

UV Inkjet Printing has demonstrated extraordinary potential in printing technology around the globe in recent years. Other than its environment-friendly trait, UV Inkjet Printing can also be applied to various printing materials due to its wide range of application. Comparing to the low-price competition invoked by paper-based printing, it achieves high added-value results from its output. While international market’s perspective on inkjet printing remains positive, most printing press in Taiwan still have doubts for the technology. In recent years, there has been a considerable growth in importing UV Width Inkjet printers in Taiwan domestically. However, working personnel in Taiwan are inexperienced in dealing with new equipment and wider selection of printing materials, therefore the issue of printers adapting to their diverse printing materials. This study will examine the five combinations of UV printer and printing materials that are common in Taiwan (brands of printers, serial number of the sprinkler head, and brands of printing ink) and three specific high-value printing substrates (glass, acrylic and melamine plywood). Through the printing experiment, the color gamut of printing materials will be re-examined. The goal of the study is to establish a standard for UV printing’s application in decoration materials, so as to provide reference for future development.

Abstract:

Yule-Nielsen spectral neugebauer (YNSN) model is widely used in printing for predicting dot area. The model’s accuracy is effected by the paper’s performance, ink kinds, wavelengths, and printing conditions. In the paper, the relation between the solid color patch’s spectral reflectance and the printing’s dark dot area is discussed. By experiments, the solid color patch’s spectral reflectance is adopted as fixed index of YNSN model, which can reduce the deviation of the dark color patch. The research has a certain significance for controlling printing quality and reducing the producing cost.

Abstract:

The confluence of three-dimensional printing, three-dimensional scanning, and the Internet will erode the dividing line between the physical and the digital worlds and will bring millions of laypeople into intimate contact with the full spectrum of intellectual property laws. One of the areas most affected by 3D printers will be three-dimensional art. This Article analyzes several ways in which 3D printing technology will affect the creation, delivery, and consumption of art. Not only does 3D printing offer great promise for creative works, but it also presents a problem of piracy that may accompany the digitization of three-dimensional works. As 3D printing technology’s relationship to intellectual property law is largely unexplored, this Article explores foundational issues regarding how copyright law applies to 3D printing technology, laying the groundwork upon which further analysis of 3D printing’s effects on copyright law may be built.

Abstract:

3D printing has been recognized to be such a game-changer in manufacturing that it has now permeated virtually every aspect of the industry, including mould and die casting. A thorough examination of 3D printing's past, present and future in the business is provided here. Casting procedures may be enhanced or drastically altered by 3D printing. The design of goods, assemblies, and parts will be transformed by 3D printing, which is more than just a manufacturing technology. With the aid of 3D printing, sand casting is a technique that can make complex components out of almost any metal alloy at a reasonable cost. Using this integration, producers may build massive components in the least amount of time. It has also established a distinctive place in other casting elements; Examples include the ceramic shell, sand mould sand core, and wax pattern, we'll learn more about sand casting and 3D printing this week.

Abstract:

Robotic 3D printing applications are rapidly growing in architecture, where they enable the introduction of new materials and bespoke geometries. However, current approaches remain limited to printing on top of a flat build bed. This limits robotic 3D printing’s impact as a sustainable technology: opportunities to customize or enhance existing elements, or to utilize complex material behaviour are missed. This paper addresses the potentials of conformal 3D printing and presents a novel and robust workflow for printing onto unknown and arbitrarily shaped 3D substrates. The workflow combines dual-resolution Robotic Scanning, Neural Network prediction and printing of PETG plastic. This integrated approach offers the advantage of responding directly to unknown geometries through automated performance design customization. This paper firstly contextualizes the work within the current state of the art of conformal printing. We then describe our methodology and the design experiment we have used to test it. We lastly describe the key findings, potentials and limitations of the work, as well as the next steps in this research.

So far the Elegia in commendationem Homeri by Simon Lemnius (1511–1550) has only been edited in an incomplete form (Daphnis 17 (2), 1988, 205 ff.), because the ending of the only known printing at that time was mould-infested and thus illegible. Due to the discovery of an undamaged printing from Wittenberg, the ending is legible as well and the text can now be edited in full, so that the meaning of the title is intelligible at last. Due to other texts bound in the same volume with the two printings, the place of storage and an indication of ownership, maybe even the as yet unknown place of printing, Wittenberg, can be presumed.

Abstract:

Three-dimensional (3D) printing, also called additive manufacture (AM), is a novel, automated method of printing a structure layer-by-layer directly from a 3D digital design model. Its potential ability to build complex shapes in a less costly and more sustainable manner may revolutionize the construction industry. There are three main 3D printing techniques: (a) contour crafting; (b) concrete printing, and (c) D-shape. As a disruptive technology, 3D printing creates a new market and value network, thus disturbing the established market. Building information modeling (BIM) is a comprehensive management approach encompassing the entire life cycle of the architecture and construction (A&C) process, including architectural planning, geometrical data, scheduling, material, equipment, resource and manufacturing data, and post-construction facility management. By maintaining safety and productivity in large-scale digital processes, BIM is critical to 3D printing’s success in construction. Integrating BIM and 3D printing techniques into A&C can potentially lead to an ecological architectural process that reduces waste and energy inefficiency, and prevents injuries and fatalities on construction sites, while increasing productivity and quality. This paper examines BIM-based 3D printing of sustainable buildings, which may revolutionize the construction industry and contribute to a sustainable environment

Abstract:

Abstract Historically characterised by its labour-intensive nature and low productivity, the construction industry is witnessing a technological revolution. Among these advancements, 3D printing stands out as a frontrunner, offering the potential to automate construction processes, reduce material waste, shorten project timelines, and mitigate risks associated with manual labour. This study explores the transformative capacity of large-scale 3D printing in construction, examining current progress, potential trajectories, and inherent limitations. Furthermore, it assesses the impact of expanded 3D printing adoption on the construction labour market. Our findings highlight 3D printing’s potential to significantly diminish the need for manual labour, addressing labour shortages, particularly in countries reliant on immigrant labour forces. However, its effectiveness may vary in regions with competitive labour costs where manual labour remains prevalent. Integrating 3D printing in construction necessitates cultivating a specialised workforce with expertise in this innovative technology. In conclusion, this study underscores the transformative influence of 3D printing in construction, offering increased efficiency, reduced labour dependency, and solutions to industry challenges. Adapting 3D printing adoption to regional labour dynamics and workforce upskilling is essential for maximising its benefits. As the construction industry evolves, embracing 3D printing emerges as a pivotal factor in shaping its future landscape.

Abstract:

AbstractThis article examines the political economy of Cairo's emerging Arabic private printing industry during the third quarter of the 19th century. I use the constituent texts of the industry to demonstrate that it developed upon the speculative model of commissioning, whereby individuals paid printers to produce particular works of their choosing. Commissioning indicates that Egyptian private printing grew from local traditions for producing handwritten texts. Nevertheless, print commissioning differed from manuscript commissioning by requiring individuals to assume great financial risk. I explore the nature and implications of this divergence through a treatise published in 1871 by Musa Kastali, a particularly prolific printer who helped to professionalize Cairene printing. Musa's treatise details his legal battle with a famous Azhari commissioner, and is unique for describing a printer's business practices. It demonstrates the importance of situating printings within their socioeconomic contexts in addition to their intellectual ones, a task which cannot be done without an appreciation for the functioning of the printing industry at a local level.

Abstract:

In spite of the advantages of high throughput and a low manufacturing cost conferred by the gravure printing method, it has been shown that antennas printed using the gravure printing method do not offer satisfactory performance because of the limitations of the conductive materials used as ink. In this article, a roll-to-roll gravure-offset printing system is proposed for the manufacturing of printed ultra-high frequency radio frequency identification (RFID) tag antennas. Antennas printed using the multi-layer gravure-offset system are also demonstrated with their performances. The gravure-offset printing system mainly consists of three printing parts, i.e. drying units, vision systems, and register control systems for multi-layer printings. In the identification range test using an RFID reader, compared to the conventional RFID tags with copper-etched antennas, which show the identification range of about 3.2 m on average, the three-layer printed antennas with bonded tag chips exhibit the identification range of about 1.8 m on average (i.e. the performance of about 60 per cent of conventional copper-etched antennas), which implies that the printed antennas could be applicable to real fields.

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.

Abstract: The healthcare industry has undergone a paradigm change thanks to three-dimensional (3D) printing. A platform technology called 3D printing enables the creation of complicated items using fewer ingredients. An advantage over traditional methods is provided by the simple development procedure. Each patient requires a unique dose of medication. The conventional "one size fits all" technique is now in use, but 3D printing has the potential to become more individualised. In this, we discuss several viewpoints on the choice of medicine, polymer, and technological considerations for 3D printing. In terms of clinical use, legal issues, and business opportunities Future 3D-printed implantable organs will likely be available, lowering waiting lists and increasing the number of lives saved.

Abstract:

The aim of this study is to explore Direct Imaging (DI) and Computer to Plate (CtP) printing technologies in Nigeria with a view to determining sustainability of DI printing standard. Methodology: Content analysis through direct field investigation, which included participant observation and key informant interview was engaged. The data collected for the comparative analysis of the strengths and challenges of DI and CtP printings were between May 2014 and June 2021. Results: This study identified high start-up cost and unavailability of spare parts and technicians as the main challenges in the use of the two technologies in Nigeria and consequent upon which there is no longer functional offset DI press in Nigeria. The CtP presses that survived continue to provide the super quality printing standard set up by the DI technology. Scientific novelty: The study discovered CtP print quality as equivalent to DI super print standard, thereby providing basis for sustainable development of DI standard in Nigerian printing industry. Practical Significance: The findings of this research have practical implications on printing industry, delivery of communication design and the Nigerian economy. The identified strength of CtP indicates availability of super print quality this far in the country, as a result create avenue for sustainable development in the affected sectors in Nigeria.

Abstract:

The purpose of the literature review is to determine the scope of 3D printing, also known as RP (Rapid Prototyping) applications in manufacturing medical model based on CJP (Collor Jet Printing) technology, with emphasis on the use in orthopedic surgery planning. The research of the presented method will be focused on the financial aspect. Researchers accept as axiomatic fact that the main buyer of the MRP (Medical Rapid Prototyping) structure will be the patient while the recipient will be the doctor or surgeon that provides the operation. Using available open-source software solutions and suitable method for the treatment of CT (Computed Tomography) scans based on filtering RAW files managed we to get the best or relatively good results allowing to exclude a human work from one of the most difficult and time-consuming processes. Total cost of 3D printings including all production processes and post-productions are about 50% lower than commercial rates (on free market) for the model of: “oscoxae” including "osfemoris" (femur length not exceeding 20 cm). In our opinion it’s "relatively positive" effect. Despite the success in the field of lowering the cost of 3D prints our work is still focused on reducing it (at least up to another 30%) by using automated-machine processing and tasks automation, as well as using another printing methods. Using 3D printings as a tools to help plan complex orthopedic surgeries make possible to extremely reduce the time of using instrumentation and the treatment time (comparing to similar surgeries carried out without using 3D printings).

Abstract:

Paper is the main print material, whose performance is a factor that effects the printing’s dot gain which is bad to image clarity and color reproduction. In the paper, Yule-Nielsen neugebauer spectral modal is analyzed , and the relation between paper’s spectral reflectance and the printing’s dot gain is discussed. By experiments, the paper’s spectral reflectance is adopted as correction index, which can reduce the dot gain value of the light color patch , and in the same printing conditions the dot gain is effected by the paper’s spectral reflectance, ink’s type, dot area percentage and wavelengths. The research has a certain significance for controlling printing quality and reducing the producing cost.

Abstract:

Abstract Digital light processing (DLP)-based three-dimensional (3D) printing technology has the advantages of speed and precision comparing with other 3D printing technologies like extrusion-based 3D printing. Therefore, it is a promising biomaterial fabrication technique for tissue engineering and regenerative medicine. When printing cell-laden biomaterials, one challenge of DLP-based bioprinting is the light scattering effect of the cells in the bioink, and therefore induce unpredictable effects on the photopolymerization process. In consequence, the DLP-based bioprinting requires extra trial-and-error efforts for parameters optimization for each specific printable structure to compensate the scattering effects induced by cells, which is often difficult and time-consuming for a machine operator. Such trial-and-error style optimization for each different structure is also very wasteful for those expensive biomaterials and cell lines. Here, we use machine learning to learn from a few trial sample printings and automatically provide printer the optimal parameters to compensate the cell-induced scattering effects. We employ a deep learning method with a learning-based data augmentation which only requires a small amount of training data. After learning from the data, the algorithm can automatically generate the printer parameters to compensate the scattering effects. Our method shows strong improvement in the intra-layer printing resolution for bioprinting, which can be further extended to solve the light scattering problems in multilayer 3D bioprinting processes.

Abstract:

To solve the problem of pigment printing’s hard handle and poor fastness, we have synthesized an amino silicone oil / acrylic emulsion blending adhesive to improve the printing handle and fastness in the paper. We studied the synthetic monomers and influencing factors to explore the best synthesis process of the acrylic emulsion polymerization. The synthetic acrylic emulsion and amino silicone were blended to explore the best printing process. We find that the printed fabrics have a good handle and significantly better rubbing fastness.

Abstract:

The pharmaceutical industry is advancing at an incredible rate. Novel drug formulations for targeted therapy have been developed all thanks to advances in modern sciences. Even so, the manufacturing sector of novel dosage forms is minimal, and the industry continues to rely on traditional drug delivery systems, particularly modified tablets. The use of 3D printing technologies in pharma companies has opened up new possibilities for printed products and device research and production. 3D Printing has slowly progressed from its original use as pre-surgical imaging templates and tooling molds to produce one-of-a-kind instruments, implants, tissue engineering scaffolds, testing platforms, and drug delivery systems. The most significant advantages of 3D printing technologies include the ability to produce small batches of drugs with custom dosages, forms, weights, and drug release profiles. The production of medicines in this manner could eventually contribute to the realization of the principle of personalized medicine. The biomedical industry and academia have also embraced 3D printing in recent years. It offers commercially available medical devices as well as a forum for cutting-edge studies in fields such as tissue and organ printing. This mini-review provides an overview of 3D printed technology in medicines.

Abstract:

Digital printing can print directly the information which will be printed on the package box by digital print machine and internet or computer, which removes the procession of color separation, makeup, plate-making in the traditional printing. The digital print can print any number package box at any time and at any place, which can realize the variable data printing, and which has a price advantage in the short version printing. Therefore, digital printing is a good method for personalized packaging printing.In digital printing, color control is important for print quality detection. In this paper the dot area percentage of cyan, magenta, yellow ink can be predicted by measuring the color’s spectral reflectance in order to control the ink’s amount in digital print and realize the color’s precise control of cyan, magenta, yellow. In the prediction model of three color ink’s dot percentage, the characteristic of spectral reflectance curves for the various color ink is analyzed, and each ink’s high reflectivity and low reflectivity which is high correlation with the dot percentage is chosen and is calculated by normalization method in order to get each ink’s dot area percentage’ prediction model. At last by measuring the paper’s spectral reflectance and the using normalization method, paper’s color can be described, and the effect of paper on monochrome color ink’s dot area percentage can be analyzed. The research has important significance for packing box’s digital printing’s color high-fidelity reproduction.

Abstract:

This review summarizes the utility of 3D-printing as a surgical adjunct, reviewing the cost–effectiveness. The relevant literature was analyzed outlining the utility and/or cost–effectiveness of 3D-printing for clinical use. Compared with existing methods, the evidence suggests an advantage of using 3D-printing as a technology in the treatment of complex clinical cases. However, in high frequency cases, the additional preoperative expenses are not justified. Considerable evidence of its clinical benefits exists for the application of 3D-printed anatomical models and teaching tools. However, the evidence supporting 3D-printing’s use as surgical guides or implantable devices is less clear. Furthermore, caution must exist when using these devices in the clinical setting due to a paucity of rigorous testing, global regulation and long-term data.

Abstract:

Digital printing ink imaging is one of main technical fields in digital printing technology development, fluorescence inkjet digital printing is provided with favorable anti-falsification, which is used widely in Securities anti-counterfeiting and labels anti-counterfeiting etc[1]. Printings coated with fluorescence inkjet ink that emits fluorescence under using short-wave ultraviolet light excitation get more favorable anti-falsification. Green fluorescent inkjet ink is composed of phosphor, resin, solvent, assistant agent etc, resin is main one of green fluorescent inkjet ink, which has a significant implication for its property. In order to discuss resins to green fluorescent inkjet ink properties, five samples of fluorescent inkjet ink are prepared, and test various performance parameters of ink samples, such as luminous intensity, surface tension, adhesive force, aridity, and so on. The study result indicated that resins have a great influence on luminous intensity, surface tension, aridity of fluorescence inkjet ink samples, surface tension and viscosity of resins immediately impact surface tension and viscosity of fluorescent inkjet ink.
