How do you calculate powder refresh cost for a quote?

Multiply the virgin powder mass added by the price per kilogram and the billable share, then add the sieving and blending charge. For 18 kg at $74/kg fully billed plus $160 handling, the quote cost is $1,492.

What is a typical powder refresh rate in metal AM?

Many titanium and nickel-alloy bureaus refresh at 30-50 percent virgin per build to hold spec, though some qualified processes run lower. The refresh mass you enter should match your validated dilution strategy for that alloy.

Why bill sieving and blending separately?

Sieving on an ultrasonic or vibratory sieve and homogenizing the blend is a fixed labor-and-equipment step per refresh, independent of how much virgin powder you add. Keeping the $160 charge separate keeps your virgin-powder math clean.

Should I bill 100 percent of the virgin powder cost?

Most bureaus do, because virgin feedstock is a hard cash outlay. The default 100 percent billable share reflects full pass-through; lowering it means you are subsidizing powder turnover to win price-sensitive work.

Does this account for powder that gets reused?

Yes indirectly — you only enter the virgin top-up mass, not the full bed. The recycled powder you carry over is already paid for, so the refresh cost captures only the new material plus conditioning labor.

Why is the effective price per kg higher than the virgin price?

Because the fixed sieving and blending charge spreads across the kilograms added. Here 18 kg of $74 powder plus $160 handling gives an effective $82.89/kg — the conditioning overhead per kilogram you should not forget.

Additive Manufacturing Service Bureau Quoting calculator

Powder Refresh Quote Cost Calculator

Powder Refresh Quote Cost is the dollar amount a metal AM bureau charges to top up its recycled powder bed with virgin powder so the blend stays within spec. Every LPBF or DMLS build consumes and partially degrades powder, and operators add virgin material at a defined refresh ratio to keep oxygen content, particle size distribution and flowability inside the qualification window. Quoting and powder-management staff use this number to recover the real cost of feedstock turnover instead of burying it in machine rate. Get it wrong and either your quotes lose to competitors or your powder budget quietly bleeds.

What this calculator does

Estimate powder refresh cost for SLS, MJF, or metal AM quotes from virgin powder mass, powder price, refresh capture, and handling charge.
a service bureau estimator needs to add powder refresh cost to a powder bed quote
It computes the quoted cost of refreshing a powder bed by combining the billable virgin powder top-up cost with a fixed sieving and blending charge.

Formula used

Captured refresh cost = virgin powder mass × virgin powder price × billable refresh share
Powder refresh quote cost = captured refresh cost + sieving/blending charge

Inputs explained

Virgin powder added per build:
Virgin powder purchase price:
Refresh mass billed to customer:
Sieving and blending charge:

How to use the result

Use it when quoting metal AM builds where you maintain a recycled powder lot and add virgin powder at a known refresh rate per build.
It models one refresh event at a single virgin price; it does not track lot-level powder aging, oxygen pickup over many cycles, or the eventual full lot disposal cost.

Current U.S. benchmarks

The producer price index for plastic resins and materials stands at 319.371 (BLS, May 2026), up 19.5% from a year earlier. Quotes priced off last quarter's material cost miss this move.
The U.S. prime lending rate is 6.75% (Federal Reserve via FRED, 2026-07-02). Payback and financing math should start from today's rate, not a remembered one.
