In the late 1990's implementation of CAD/CAM systems in 3D printer has been led to many changes in the jewelry industry. Low cost 3D printer has been started advertising in the jewelry in 2009 after expiration of key patents of FDM scheme. Mass jewelry production process will vary in appliance with direct production process of 3D printer production line. The studies presented in this variation is the jewelry manufacturing process using a 3D Printer and the different metals with different colors were also produced for bonding the prototype jewelry. Increasing the possibilities of 3D printer through them, presents a variety of jewelry mass production methods.

Today, 3D printer is all the more impressive because it is reducing complex product process than other existing methods (e.g. CNC) fast handling customer's various demands. If 3D printer become popular, that can shift industrial production methods and consumption patterns. Therefore 3D printer cross lips as the second industrial Revolution. This paper will classify the various kind of 3D printers among their properties, analyze merits and demerits of each ones, and proposed the direction of 3D printers future.

Due to the expiration of the 3D printer's patent, the articles covering the market activation and bright prospects for the future industry are being released. What are the requirements for the 3D printer to become popular like a general printer? To get the answer, on-line survey was performed for the activation of 3D printer. As a result, tit is observed that he public prefers creative printer and figure, and prefers to use through pay or free download rather than designing digital blueprint, which is output data. For the activation and popularization of 3D printer, figure is familiar to the public who are frequently exposed to image media contents, and it also has motivation factor to use and purchase 3D printer. For distribution of digital blueprint of figure content, the preparation of related law and regulation and activation of online market would be of help for activation of 3D printer.

Libraries both in South Korea and abroad have been adopting 3D printers and related service. This indicates the need for documented 3D printer use policy to facilitate the service. This study investigates 3D printer use policies of libraries in Korea and best practices of the United States, and suggests contents for 3D printer use policies in Korea. The finding shows that Korean libraries with 3D printers did not have systematic and documented 3D printer use policies. After conducting content analysis of 16 best practices of 3D printer use policies from libraries in the United States, the authors identified five themes (purpose, users, procedures, limitations of use, and liability) and 21 sub-themes. The findings are informative for Korean libraries to develop 3D printer use policies and to understand various considerations in implementing 3D printer services.

Nevertheless 3D printer is propagated fast, it is difficult for us of using 3D printer at the same time because of 3D printer's slow velocity. Existing solution is to print using SD card which moves files and on PC but this method is spend too much time and can not be showed status of printing. Yet we have no 3D printer software solution which is controlled and printed remotely. Therefore, this 3D printer software solution makes 3D printer be connected on internet networks and selected to use it on smart App. And it is controlled and printed remotely. In my paper, to build an Android App. which can execute these functions, an effective analysis & design using UML and implementation method will be presented.

The development of the industrial revolution can confirm the paradigm of manufacturing is changing from the mass production of small varieties to the form of small-scale production of many varieties. That is a form that can reduce the burden of indiscriminate raising of producers and a change in the industrial form that seeks to make up for the problems of the productivity portion that should change as modern society develops. Looking at the 3D printing environment, there are many problems in reaching the final stage of printing. The problem is not just the low-cost, low-end 3D Pirnter, but the high-priced 3D Printers released as finished products also show the same symptoms. This can cause anxiety factors in the printing process. Therefore, the research was conducted to compensate such problems. Based on the research, we propose the design of IoT beacon-based 3D Printer remote safety and quality control system targeting 3D Printer individual users.

3D printing is a technology that converts a computer-generated 3D model into a real object with additive manufacturing technology. A majority of 3D printing technologies uses one material, and this is considered a limitation. In this study, we developed a multi-material 3D printer by adopting dual resin vat and cleaning system with DLP (Digital Light Processing) 3D printing technology. The developed multi-material DLP 3D printer is composed of a manufacturing system, cleaning system, transporting system, and automatic resin recharging system. Various 3D structures were 3D printed with two materials, thus demonstrating the potential. Printing performance of the multi-material DLP 3D printer was studied by performing a comparative surface roughness test and tension test on specimens composed of one material as well as those composed of two materials.

Recent promising technologies of the manufacturing sector interest, and the interest in 3D printing that is expected to cause a huge ripple effect rapidly, and various types of products advertised in accordance with the falling price of 3D printers is spreading. However, the personal 3D printers that are currently being advertised is used for Injection output of the simple type that does not require a high processing precision in accordance with the limitation of technical performance, and consumer satisfaction is very low. In this paper, we propose a 3D printer, 3D precision to overcome existing limitations in the way the printer's high SLA 3D printer that combines injection method and the LSU (Laser Scanning Unit) in the office laser printer polygon mirror scanning method. 3D printers which are proposed to improve the accuracy and manufacturing speed is expected to replace the existing entry-level 3D printer.

Recently, 3D printer technology has been attracting attention in various industrial fields, and research papers are being conducted to utilize 3D printers in the construction industry. Actual structures such as bridges and buildings are being printed to 3D printers, and various applications such as mock-up structures using 3D printers are being proposed. In order to utilize 3D printer technology in the construction field, a 3D model is required, and the 3D BIM data produced at the design stage can be printed by a 3D printers, saving the cost and time of 3D model generation. However, 3D BIM data often does not satisfy the conditions for 3D printer output, causing many errors on output. In this paper, authors propose a problem analysis for 3D BIM model output to 3D printer and a method for reducing errors in 3D printing process of 3D BIM model. In addition, this paper presents a practical application of 3D model output from 3D printer.

In this paper, we classify 3D printer technologies which are becoming a recent issue, and analyzed the features and limitations of the technology. As a result, we can see that there is no 3D printer technology that can produce a completely free-curved architectural structure. In order to construct a completely free-curved architectural structure with a 3D printer, it is necessary to draw up a new concept technique that complements the drawbacks of the two methods.
