Resin Cost Per Part Calculator
Resin cost per part should include the parts, supports, rafts, trapped resin, and rejected pieces that belong to the build. This calculator divides total resin spend by accepted parts for service bureau quoting and production cost tracking.
What this calculator does
- Calculate photopolymer resin cost per accepted part from total resin cost and good part count.
- an estimator needs a resin material cost per accepted SLA or DLP part
- Returns resin material cost assigned to each accepted printed part.
Formula used
- Raw resin cost per part = total resin cost ÷ accepted resin parts
- Reported resin cost per part = raw cost × conversion factor
Inputs explained
- Total resin cost: undefined
- Accepted resin parts: undefined
- Cost conversion factor: undefined
How to use the result
- Use it for resin quote lines, job costing, and comparing hollowing or support orientation options.
- It does not include wash solvent, UV curing, labor, machine depreciation, or inspection cost.
Common questions
- Should supports be included in total resin cost? Yes. Include supports and rafts because they consume resin needed to make the accepted part.
- What if the build has mixed parts? Allocate total resin cost by part volume, customer line item, or another consistent costing rule.
- Should rejected parts count as accepted parts? No. Keep rejected material in the numerator and divide by sellable parts.
- What decision does this support? Use it to set material pricing, compare orientations, or check whether minimum charges are needed.
