Abstract

The present study investigates the effect of the concentration of flexible resin on the dimensional accuracy of mixtures product manufactured by 3D printing using SLA technology. Specimens were designed and according to the ASTM D412 standard. Ten variations of resin mixtures were examined. The concentrations of the flexible resins were varied from 10% to 100%. Measurements of accuracy dimension were conducted on the fabricated specimens, and the average deviation was used to estimate the dimensional accuracy. The study reveals the least deviation in dimensions in the 10% flexible resin containing mixture and the highest in the 60% flexible resin containing mixture. The results explain the fabrication tendency of flexible resins in dimensional accuracy for 3D printing.

Abstract

As toddlerhood is a golden milestone during children's growth, high-protein foods like fish are strongly recommended to avoid stunting. On the other hand, a series of proper aeration is often required to support aquaculture in fish farming. Here, the technology of microbubble generators (MBG) can be properly applied. In the present work, subsequent activities which were carried out comprised the design manufacturing, installation, and also trial of MBG units, followed by site exposures. During the first exposure, two sessions covering a talk show and another practical work were conducted. The working principle of MBG was discussed in the first session, while the installation and operation were practically elaborated in the second session. Additionally, in the second exposure, several units of microbubble generators were granted to be applied to the community’s fish farming.

Abstract

In the present work, a simple aeration technology, utilizing the concept of a microbubble generator (MBG), was applied to an aquaculture field. It aims to support aeration by increasing the dissolved oxygen (DO) in the water. Subsequent supporting activities were carried out, comprising design, optimization and manufacturing, installation, and trials of MBG units, followed by site exposures. During one of the exposures, two sessions covering a discussion and another practical work were conducted. The working principle of the MBG was briefly explained in the first session, while the installation and operation were practically elaborated in the second session. Additionally, two units of MBG appliances were granted to be applied on the exposure site, namely Usaha Budidaya Ikan Senandung Betta. During the following exposure, the MBG implementation was evaluated through a series of DO measurements. Here, the measurement reached a range of 5.7 – 5.9 mg/L by operating the MBG. This means that the MBG increases the DO by around 1.5 mg/L.

Abstract

A small leakage in the primary circuit of a nuclear power plant reactor may trigger the occurrence of countercurrent flow which probably develops into a flooding regime followed by the zero penetration caused core cooling failure. During extensive studies in the flooding phenomena in the PWR hot leg, the geometry effects have been widely investigated. The present study investigates the effects of I/D ratios of the riser on the interfacial fluctuations during the counter-current flow on a 1/30 scaled down PWR hot leg geometry. Here, the liquid film fluctuations were acquired by using parallel wire array probes on the basis of a conductance concept. Three I/D ratios which were varied consisted 1.9 (R1), 3.9 (R2) and 8.3 (R3). The obtained data were analyzed on the basis of both time and frequency domains. From the PDF the flooding regime obtains multimodal distributions, while the PSD approaches lower frequencies with higher magnitudes corresponding to either the occurrence of water blockage or slugs. Keywords: I/D ratio, water level fluctuation, counter-current flow, PWR hot leg, parallel wire array probe, stochastic analysis.

Abstract

Over the years, technologies of 3D printing have enhanced the opportunity to ease the production of complex geometries. In particular, it further implies that the flexibility of materials is of a great importance. Therefore, the works covering studies of applicability on novel materials in rapid prototyping contribute to the development of additive manufacturing. The present work experimentally investigates a mechanical property, namely tensile strength, of 3D printing materials on the basis of the concentration of flexible-standard resins. Tensile strengths were obtained by a series of tensile tests. Here, the result reveals that the tensile strength monotonously decreases as the increase of the concentration of flexible resin’s concentration. Moreover, an ANOVA analysis strongly implies a consistent relationship between the tensile strength and the material’s mixture.
