Accounting Formulas for Additive Manufacturing

Labor time and cost is 0 for Printing, Laser Sintering, Resin Curing, and Part Curing. Labor time depends on powder removal time for Metal Sintering (see Metal Sintering Formulas). The other processes use the following Labor Cost formulas:

Labor Cost = Labor Time * Labor Rate / Final Yield

Labor cost is a function of the following:

• Labor time (see formula below)

• Labor rate (specified by the machine property Labor Rate)

• Final yield (see Yield Formulas for Additive Manufacturing)

Labor Time = Cycle Time * Labor Time Standard * Number of Operators

Labor time is the product of the following:

• Cycle time (see the sections on the individual processes, below)

• Labor time standard: specified as the machine property Labor Time Standard. This multiplier is used to account for otherwise unaccounted for factors that affect labor time, such as operator fatigue or time spent by the operator for cleaning or maintenance.

• Number of operators (specified by the machine property Number of Operators)
