일반적인 평판 프린터 시스템은 PC와 전용 S/W로 구성되어 사용에 불편함이 존재한다. 결국, 평판 프린터 시스템 구성의 간소화, 스마트화 등을 통해 다양한 형태의 프린팅을 쉽고 편리하게 사용할 수 있는 기술이 필요하다. 즉, 한 대의 프린터로 여러 종류의 소재에 인쇄가 가능하며, 다양한 형태의 상품을 인쇄할 수 있는 다입체 프린터에 대한 수요가 증가하고 있다. 따라서, 본 논문에서는 Head Encoder/Trigger 제어를 이용하여 다입체 인쇄가 가능한 평판 프린터 시스템을 개발하였다. 이를 위해, 평판 프린터 내부 모듈을 입력 형태 감지 센서를 연계시키고, 별도의 메인 콘트롤러를 통해 프린터의 Head Encoder와 Head Trigger 신호에 의해 모든 동작 상태를 제어하는 평판 프린터를 개발하였다. 이를 통해, IoT 기술의 발전 및 보급의 확산으로 산업 전반에 걸쳐 스마트 환경의 프린터 제어가 발전된 형태로 확대될 것이며, 향후 3D 프린팅 산업 발전에 기여할 것으로 기대된다.

In this paper, the type of inkjet heads and the control of head of inkjet printer are surveyed. The electronic parts of inkjet printer are composed of main- board and sub-board. The inkjet head is controlled by using these boards. The results from silver ink jetting experiment are given. The results show that the implemented inkjet system can give a satisfactory performance.

In this paper, development of Thermal Printer Head(TPH) controller by using gate array having high reliability and good performance is proposed. Over the 3000 gates are performed to control print image data signals and relative peripheral hardwares. The proposed gate array has TPH control circuit, print control and step motor drive, and print image data control, decoder output control parts. This TPH controller will be a good application to FAX or label printer and barcode printers.

Printing technology is a very useful method in the several process of industrial fabrication due to noncontact and fast pattern generation. To make micro pattern, we investigate the electrostatic induced inkjet printer head for micro droplet generation and drop-on-demand jetting. In order to achieve the drop-on-demand micro droplet ejection by the electrostatic induced inkjet printer head, the pulsed DC voltage is supplied. In order to find optimal pulse conditions, we tested jetting performance for various bias and pulse voltages for drop-on-demand ejection. In this result, we have successful drop-on-demand operation and micro patterning. Therefore, our novel electrostatic induced inkjet head printing system will be applied industrial area comparing conventional printing technology.

This paper describes design techniques of general purpose thermal array printer, especially easily applicable to medical measurement equipment. The'general'means that the proposed thermal array printer can be applied to not only medical field but other industrial field by establishing the eligible protocol. The thermal array printer is composed of i)MPU and its peripherals ii)printer head control, iii)diverse protection circuits, and iv)serial communication. In this paper the performance of the proposed thermal array printer was evaluated by applying to an 3 channel electrocardiogram recorder. The propped system can support'Hangul'text as well as alphanumeric characters and any bitmap image.

In this paper, we intend to develop optimized design algorithm by deciding design parameters which are considered in the first design stage of inkjet printer head. thus, the parameters are such as electric pulse, input voltage of actuator to operate actuator, shape dimension of actuator an so on. in the first design stage, according to such parameters, a lot of time and money to develop inkject printer head are needed. to reduce trial and error and to save development time in the first design stage, optimized design algorithm is required all the more. design algorithm was developed via commercial FE analysis code(ANSYS & COENTOR) for the readability and convenience of algorithm. the reasonability of algorithm was verified by implementing analysis of system stage based on the data of piezoelectric actuator which was designed through algorithm.

This paper describes a method of precise estimation for printing time and material consumption which are directly related to the 3D printing cost. Printing process and head motion of 3D printers using digital printing head, which is analyzed by its digitized steps, is rapidly simulated without slicing to calculate estimated printing results. Using this method, printing time and material usage of 3D printer were estimated quickly and precisely and compared to the real printing result. Applying compensation using the printing parameters, transferred from the 3D printer to the printing estimation system, even more accurate estimation is achieved. This method is used in the 3D Sprint software.

SFF(solid freeform fabrication) is another name of RP(rapid prototyping). The SFFS for office type wishes to develop system that can produce small object such as hand phone, cup, accessory etc. with high speed, and also intend suitable system in office environment by compact design, and buy easily by inexpensive price. As can manufacture high speed in existent SFF process technology, representative process that have competitive power in price is 3DP (three dimensional printing) technology. The 3DP technology is way to have general two dimensional printing technology and prints to three dimension, is technology that make three-dimensional solid freeform that want binder doing jetting selectively on powder through printer head. We designed and manufactured SFFS for office based on 3DP process technology design and manufactured, and composed head system so that use 3 printer heads at the same time to improve the fabrication speed of system. We used printer head of INCJET company and cartridge used HP45 series model who can buy easily in general city. And we directly fabricated three dimensional solid freeform using developed SFFS for office type.

This paper proposes how to solve a problem of FDM 3D printer's irregular output when changing volume of extrusion, adjusting movement speed of the printer's head and a way to fill new inner part. Existing slicers adjust directly to change the rotation speed of the stepper. In this method, the change of the extrusion area is delayed due to the gap between the stepper and the nozzle, so that precise control is difficult. We control the extrusion area adjusting the moving speed of the print head and making constantly the rotation speed of the stepper. Thus, the output time can be shortened by generating an efficient path having a short travel distance. For evaluation, we applied our method to lithophanes with detailed variation. Comparing existing methods, our method reduced output time at least 30%.
