• Micro-featured mold insert
• form accuracy
• cost reduction
• micro-hot embossing process

This study demonstrated a method for manufacturing a micro-featured mold insert of Fresnel lens. The transcription rate of this process is about 92.5%. A plastic Fresnel lens was fabricated using micro-hot embossing process. The transcription rate of the embossed part is about 95.1%. The micro-featured mold insert not only reduces the fabrication cost, but has higher form accuracy as well. In comparison with conventional method for fabricating a pair of mold insert, a cost reduction of 60.4% can be achieved using the hybrid method proposed in this study.
