3D pricing
Price per gram vs price per hour in 3D printing
Charging only for material or only for time can ignore part of the real production cost.
Per gram
Simple, but it can undervalue slow, lightweight parts.
Per hour
Reflects machine occupancy, but does not distinguish expensive materials or high consumption.
Combined model
A stronger formula combines material, time, preparation, risk, post-processing and margin.
