In this study, we aimed to apply 3D digital printing to basic clothing production and to propose futuristic fashion design and production methods that correspond to contemporary trends. Literature on future trends, dynamism, mechanical aesthetics, and experimentalism were used to define the characteristics of "futurism." Based on theoretical considerations about futurism, we created fashion designs using 3D digital printing methods. These designs were produced using the aesthetic characteristics of futurism; the 3D digital clothing program; and application of digital printing technologies to futuristic silhouettes, colors, and materials. The results were as follows: First, with the application of futurism as a fashion motif, we pursued collaboration between artistic work and fashion, and we then explored the possibility of creative expression. Second, harmony between achromatic and chromatic colors revealed even better dynamism and activeness, and the potential to express dynamism was observed. Third, with the development of fashion design processes based on 3D digital printing methodologies, it was found to be possible to eliminate the limitations of time and space, solve problems related to limited budget or communication, and positively influence the fashion industry by enhancing convenience and diversity. Fourth, with the development of fashion design that utilizes digital printing, it was found that problems related to time, space, or limited budget were able to be solved, as compared to the use of traditional printing and image reproduction.

This study is to review the development of calico printing pattern design for fabric through historical perspective. Calico is a cotton cloth named from Calicut, a city of India. It was first brought to England by the East India company in 1621. Although the name is generally given and plain white cotton cloth, and in America it is applied to small-scale printed cottons, today it applies to indian cotton cloth, coarse or fine, woven with colored geometrical large-scale and small-scale patterns, painted or printed. Therefore this paper proposes the classification and feature extraction of calico printing pattern from the early of 16th century to 21th century. The results of this study can be effectively applied to develop competitive calico pattern design in domestic cotton textile industry.

surface texture denotes set of tiny repetitive geometric features on an object surface. 3D Printing can readily create a surface of controlled macro-textures of high geometric complexity. Designing surface textures for 3D Printing, however, is difficult due to complex macro-structure of the tiny texture geometry since it needs to be compatible with the non-traditioal manufacturing method. In this paper we propose a visual simulation technique involving development of a virtual model-an intermediate geometric model-of the surface texture design prior to fabricating the physical model. Careful examination of the virtual model before the actual fabrication can help minimize unwanted design iterations. The proposed technique demonstrated visualization capability by comparing the virtual model with the physical model for several test cases.

A design approach using a one-dimensional (1D) lumped model was studied and applied to an industrial inkjet printing head design for micro patterning on printed circuit boards. For an accurate analysis, a three-dimensional piezoelectric-driven actuator model was analyzed and its jetting characteristics were applied to 1Danalysis model. The performance of the 1D lumped model was verified by comparing measured and simulated results. The developed 1D model helped to optimize the design and configuration of the inkjet head and could be implemented in the design of multi-nozzle inkjet printing heads to improve the jetting frequency and minimize crosstalk.

With its technical development, digital printing is being universally introduced to the mass production of clothing factories. At the same time, many fashion platforms have been made for customers' participation using digital printing, and a tool is provided in platforms for customers to make designs. However, there is no sufficient solution in the production stage for automatically converting a customer's design into a file before printing other than designating a square area for the pattern designed by the customer. That is, if 30 different designs come in from customers for one shirt, designers have to do the work of reproducing the design on the clothing pattern in the same location and in the same angle, and this work requires a great deal of manpower. Therefore, it is necessary to develop a technology which can let the customer make the design and, at the same time, reflect it in the clothing pattern. This is defined in relation to the existing clothing pattern with digital printing. This study yields a clothing pattern for digital printing which reflects a customer's design in real time by matching the diagram area where a customer designs on a given clothing model and the area where a standard pattern reflects the customer's actual design information. Designers can substitute the complex mapping operation of programmers with a simple area-matching operation. As there is no limit to clothing designs, the variousfashion design creations of designers and the diverse customizing demands of customers can be satisfied at low cost with high efficiency. This is not restricted to T-shirts or eco-bags but can be applied to all woven wear, including men's, women's, and children's clothing, except knitwear.

In this study, the optimal process condition was induced about the pillar arrangement process of applying the screen printing method in the manufacture process of vacuum glazing panel. The high precision screen printing is technology which pushes out the paste and spreads it by using the squeegee on the stainless steel plate in which the pattern is formed. The screen printing method is much used in the flat panel display field including the LCD, PDP, FED, organic EL, and etc for forming the high precision micro-pattern. Also a number of studies of screen printing method have been conducted as the method for the cost down through the improvement of productivity. The screen printing method has many parameters. So we used Taguchi method in order to decrease test frequencies and optimize this parameters efficiently. In this study, experiments of pillar arrangement were performed by using Taguchi experimental design. We analyzed experimental results and obtained optimal conditions which are 4 m/s of squeegee speed, $40^{\circ}$ of squeegee angle and distance between metal mask and glass.

Recently, the patent rights for 3D printing technology have expired, while 3D printers with RP (Rapid Prototyping or Additive Manufacturing) and 3D printing technologies are receiving attention. In particular, the development of 3D printers is rapid in Korea, thanks to the increasing sales and popularity of FDM (Fused Deposition Modeling or Fused Filament Fabrication) 3D printers. However, the quality and productivity of the FDM 3D Printer are not good, so customers prefer the DLP (Digital Light Processing) method to avoid these shortcomings. The DLP method has high quality and productivity. However, because of the stereolithography equipment, it has few studies compared to optimal values for elements then FDM 3D printing study. In this study, to find the optimal conditions for 3D printing with the DLP method, the aim is to obtain the optimal values (strength, final time, quality) by changing the light exposure time, layer thickness, and z-axis speed.

Reverse engineering involves duplicating a physical part by measuring and analyzing its physical dimensions, features, and material properties. By combining reverse engineering with three-dimensional (3D) printing, engineers can simply fabricate and evaluate functional prototypes. This design methodology has been attracting increasing interest with the advent of the Fourth Industrial Revolution. In the present study, we apply reverse engineering and 3D printing technologies to evaluate a fabricated automotive inner ring prototype. Through 3D printing, inner rings of various densities were prepared. Their physical dimensions were measured with a 3D scanning system. Of our interest was the effect of inner ring density on the physical dimensions of the fabricated prototype. We compared the design dimensions and physical dimensions of the fabricated prototypes. The results revealed that even the 20% density of inner ring was effective for 3D printing in terms of satisfying the design requirements.

Recently, 3D printing technology has gained increased attention in the manufacturing industry because it allows the manufacturing of complex but sophisticated structures as well as moderate production speed. Owing to advantages of 3D printers, such as flexible design, customization, rapid prototyping, and ease of access, can also be advantageous to sensor developments, 3D printing demands have increased in various active device fields, including sensor manufacturing. In particular, 3D printing technology is of significant interest in tactile sensor development where piezoelectric materials are typically embedded to acquire voltage signals from external stimuli. In regard with piezoelectricity, researchers have worked with various piezoelectric materials to achieve high piezoelectric response, but the structural approach is limited because ceramics have been regarded as challenging materials for complex design owing to their limited manufacturing methods. If appropriate piezoelectric materials and approaches to design are used, sensors can be fabricated with the improved piezoelectric response and high sensitivity that cannot be found in common bulk materials. In this study, various 3D printing technologies, material combinations, and applications of various piezoelectric sensors using the 3D printing method are reviewed.
