ROI Calculation Logic

Implementing this technology could automate manual printing processes on complex curved surfaces, potentially reducing personnel costs. Specifically, an 80% reduction in annual labor costs for two skilled operators (assuming $40K/operator annually) could save ~$64K per year (AI est.). Furthermore, reducing the defect rate from 5% to 2% is estimated to save ~$130K annually in material and rework costs (AI est.), based on an annual production of 100,000 units, $0.70/unit material cost (AI est.), and $1.30/unit rework cost (AI est.). The total estimated annual savings could reach ~$195K (AI est.).
