ROI Calculation Logic

Assuming a company manufactures 1 million micro-droplets annually, conventional technology incurs an estimated ~$350K/year in device manufacturing and management costs (including labor, materials, and defect rates). This technology, with its hole-less structure and high-density arrangement, could reduce device manufacturing costs by 20% and management effort by 10%. This translates to an estimated ~$100K/year in direct cost savings (from ~$350K to ~$250K). Additionally, a 30% increase in productivity due to high-density integration could avoid ~$50K/year in lost sales opportunities, leading to a total economic impact of over ~$150K/year (AI est.).
