Abstract
The objectives of this research were 1) to design and develop Namo pattern molds using 3D printing technology, 2) to compare the thermal properties and material efficiency between ABS and PLA plastics in the batik production process, and 3) to develop and evaluate a knowledge set on mold fabrication for technology transfer to batik producers in Nakhon Si Thammarat province. Using a Research and Development (R&D) methodology, the study combined engineering testing with data collection from a pilot group and local batik producers. The results revealed that the developed molds were accurate to the traditional identity and reduced production costs by 94.60% compared to metal molds. ABS was found to be the most suitable material due to its high dimensional stability with a deformation rate of only 0.15% during immersion in hot wax, whereas PLA suffered structural failure. The developed knowledge set achieved an efficiency (E1/E2) of 93.20/90.00 with the highest level of user satisfaction. This research contributes a practical framework for integrating 3D printing technology into traditional crafts, enhancing self-reliance and creative competitiveness for community enterprises.
