Additive Manufacturing calculator
Powder Usage Calculator
Powder bed jobs consume fused part powder, trapped cake, refresh material, and handling losses. This calculator estimates required powder mass from part count or build quantity, expected powder per part, and recovery efficiency.
What this calculator does
- Estimate powder required for SLS, MJF, binder jet, or metal powder bed builds from build quantity, powder per part, and recovery efficiency.
- an additive manufacturing engineer needs powder mass before releasing a powder bed build
- Returns powder mass to plan for the build after recovery losses.
Formula used
- Theoretical powder = build quantity × powder required per part
- Required powder = theoretical powder ÷ powder recovery efficiency
Inputs explained
- Build quantity: undefined
- Powder required per part: undefined
- Powder recovery efficiency: undefined
How to use the result
- Use it for SLS, MJF, binder jet, EBM, and DMLS material planning before loading powder or quoting a job.
- It does not validate powder chemistry, sieve results, oxygen pickup, lot traceability, or customer refresh requirements.
Common questions
- Should unfused powder be included? Include expected unrecovered or downgraded powder through the recovery efficiency input.
- Can I use pounds instead of kilograms? Use kilograms as labeled, or convert every powder input and result consistently.
- How is this different from refresh rate? Powder usage estimates mass required; refresh rate measures the new-powder percentage in the blend.
- How do I use the result? Reserve powder lots, confirm inventory, and estimate material cost or reuse savings.
