  • We wanted to check The feasibility of substituting the manual ceramic packaging technology with 3D digital technology using cotton pad packaging material was examined. To examine the shock absorption, vibration resistance and compression resistance of 3D packaging material printed out by using TPU material, composite vibration, and packaging compression and drop tests were conducted. As the results of the tests, the 3D packaging material displayed vibration resistance that has been improved by approximately 10~20% based on the damping ratio of the composite vibration test, compression resistance performances that are more than 5 times higher, and shock absorption performance was also improved as the packaged object was not broken in the six-sided drop test. Based on these results, it is determined that it would be possible to secure the reusability of the ceramic packaging materials and simplify packaging techniques, and to present diversity in the packaging materials and packaging technologies.

  • MRI scan is a useful method in the diagnosis of musculoskeletal excellent contrast of the organization. Depending on the patient's musculoskeletal examinations state the type of aids provided the aid is used there is also challenging as well as the costs do not vary. This study was produced by the use of 3D printing technology, an MRI aids. Aids in the production process, then through 3D modeling and then convert stl files using (3D MAX.2014, Fusion360) slicing programs (Cubicreater 2.1ver., Cura 15.4ver) converted to G-code printed on the FDM scheme (Cubicon Style, output was MICRO MAKE). Output is, but in the FDM to evaluate the SNR on the MRI images were compared to the test is the case before use, and then to produce a Water Phantom case of a PLA, ABS, a TPU thickness 3mm, using aids before, It was evaluated in a clinical image after qualitatively. Obtaining an image of SNR Warter Phantom appeared to have been evaluated as T1 NON $123.778{\pm}28.492$, PLA $123.522{\pm}28.373$, ABS $124.461{\pm}25.716$, TPU $124.843{\pm}27.272$. T2 NON $127.421{\pm}26.949$, was rated as PLA $124.501{\pm}27.768$, ABS $128.663{\pm}26.549$, TPU $130.171{\pm}25.998$. The results did not show statistically significant differences. The use of assistive devices before and after images Clinical evaluation method palliative $3.20{\pm}0.88$, $3.95{\pm}0.76$ after using the aids used to aid improved the quality of the image. Production of the auxiliary mechanism using a future 3D printing is expected are thought to be used clinically, it can be an aid making safe and comfortable than the inspection of the patient is an alternative to improve the problems of the aids used in the conventional do.
