Abstract

The development of manufacturing technology to be able to result products with a good level of precision, high geometry complexity, time of production can be regulated by market absorptive capacity and product prices as low as possible. Technologies developed for prototyping is one breakthrough to shorten the process of preparation before deploying a mass production system. Multi Material Deposition Indirect Sintering (MMD-IS) is a development of Rapid Prototyping (RP) technology. Many methods are used as a tool deposition powder on RP technology method one of the most widely used method Screw Nozzle Feeder Hopper. In this study, expected to get the parameters to determine the nature of the powder can flow on the deposition method Screw Feeder Hopper Nozzle by varying several parameters including angle hoper, roughness hoper wall materials and the installation of the mixer so that the powder flow properties are able to optimum. Tests performed on silica powder material with 150 mesh size variation (100 μm), 200 (75 μm), 250 (58 μm), and 350 (43 μm). Hoper varied angles of 20°, 22°, and 25°. Deposition method using a screw feeder which has a helicoide surface as a carrier mechanism by varying the stirrer and the addition of devices without a stirrer. From the test results showed that the best flow capacity happens to hoper wall material made of glass material has the lowest surface roughness value with hoper angle 25° where there is a pattern of flow is funnel flow. While the addition of the mixer device proven to increase flowability of silica powder.
