Additive Manufacturing calculator
Heat Treatment Batch Cost Calculator
Metal AM and some polymer processes require stress relief, annealing, or thermal post-cure. This calculator estimates the energy portion of a heat-treatment batch so finishing cost and batch economics are not overlooked.
What this calculator does
- Estimate additive heat-treatment energy cost per batch and per part from furnace load, cycle time, power rate, and parts processed.
- a post-processing engineer or estimator needs furnace energy cost for an additive batch
- Returns the energy cost for one additive heat-treatment batch and the cost per part.
Formula used
- Energy used = connected load × cycle time
- Batch energy cost = energy used × energy rate
Inputs explained
- Furnace connected load: undefined
- Heat-treatment cycle time: undefined
- Energy rate: undefined
- Parts in heat-treat batch: undefined
How to use the result
- Use it for metal stress relief, polymer annealing, thermal cure, and post-build cost estimates.
- It covers energy only; furnace labor, fixturing, gas, certification, maintenance, and outside processing fees may be larger.
Common questions
- Should warm-up time be included? Include warm-up, soak, controlled cool, and hold time if the furnace consumes energy and blocks the batch.
- What if the furnace cycles below connected load? Use an average measured kW if available instead of nameplate connected load.
- Can this price outsourced heat treat? No. Use supplier pricing for outsourced work; this estimates internal energy cost.
- How should the result be used? Add it to post-processing or part cost, especially for small batches where cost per part rises.
