| Abstract | Natural rubber latex (NRL), an abundant material in Thailand, has been researched as an alternative part material for Selective Vacuum Manufacturing (SVM). SVM is a simple and inexpensive rapid prototyping technique that combines sand casting and powder sintering processes to create a prototype layer by layer. A preliminary study on applying NRL to SVM technique had suggested replacement of support material to improve surface quality of the prototype. Presented in this paper is an investigation on using table salt as new support material and process parameters identification for filling and curing process. Table salt with controlled particle size between 52-76 μ m was experimented by premixing with various compositions of flour and vinegar in order to improve cohesive force between particles and to prevent NRL infiltration problem respectively. Results illustrated the support material prepared with flour 2% w/w and vinegar 3% w/w can improve surface quality of the rubber prototype. Another set of experiment was conducted to determine suitable condition of filling process. The result showed that flow rate of 0.058 ml/s could provide a good NRL layer appearance. Finally, the last experiment was to find suitable curing temperature. Results illustrated that 195ºC gave the shortest curing time at 90 seconds and did not degrade the NRL. |
