Why calculators disagree
An instant calculator has to choose assumptions quickly, often before the full use case is clear.
- Different tools estimate support cleanup, print orientation, failure risk, and finish differently
- Some include delivery, taxes, or handling differently while others show only a starting number
- Material, color, tolerance, infill, layer height, and quantity can change the practical quote
- A low instant estimate may still need review when the part is fragile, fit-critical, or hard to print
