The price follows the physics.
MJF and SAF share the build-share arithmetic of SLS: a part pays for its fraction of a realistic full build, plus its own powder and handling. What differs is the consumables. Fusing agent is printed into the part, so it follows volume; detailing agent outlines the surface, so it follows area. A part that is all surface costs differently from one that is all mass, and a calculator that ignores the agents gets both wrong. Printhead wear, a lower refresh ratio and a faster build per millimetre are separate settings for the same reason.
- 01
Build share
As with SLS, a part pays for the share of a full build its cell takes, so packing decides much of the price.
- 02
Fusing and detailing agents
Bought by the litre and used by volume and by surface. Leave them out and every MJF price is too low.
- 03
Build height
Recoat and print passes per millimetre set the machine time for the whole build.
- 04
Cooling
Natural cooling holds a build unit for hours; fast cooling frees it sooner. Either way it is occupancy you pay for.
- 05
Powder refresh
MJF PA12 usually needs less virgin powder per build than SLS, but the refresh is still waste every build pays.
- 06
Depowdering, blasting and dyeing
Parts come out grey; bead blasting is standard and dyeing black is the common finish, each per-part labour.
Measured from the file. Priced on your machines.
Measured from the geometry
- The oriented bounding box and the gap you keep. The part’s cell, and therefore its share of the build.
- Volume and surface area. Fusing agent follows volume; detailing agent follows the surface it outlines.
- Height. Recoat and print passes per millimetre: the machine-time driver.
- Wall thickness and trapped volume. The same depowdering limits SLS has, at the finer resolution of MJF.
- Its size against the build unit. An oversize part is tried on the diagonal before it is refused.
Configured by you
- Gap and nesting efficiency. How densely your nester really packs a cake, alone and in a full build. Calibratable.
- Build time per mm of height. Usually faster than SLS, and yours to set, or to fit from your own builds.
- Refresh ratio. Usually lower than SLS on PA12, and yours to state rather than ours to assume.
- Agent usage per cm³ and per cm². Fusing agent per cubic centimetre of part and detailing agent per square centimetre of surface, priced as consumables. The cost most spreadsheets leave out.
- Cooling, printhead life and depowdering. Natural or fast cooling, printhead wear per build, and the labour after the build.
What your buyer sees
- Grey PA12 as it comes, or dyed black, or vibro-polished: whatever you offer.
- The quantity break that comes from sharing a build.
- A trapped-powder or thin-wall warning before they order, not a phone call afterwards.
- Lead times you set, which should allow for cooling, because cooling is real.
As with SLS, the build is the unit of cost: ten parts in one cake pay a tenth of it each, and nesting efficiency improves as the quantity grows. Agents, powder and depowdering stay per part, so the curve flattens once the build is full.

MJF quoting, answered
Is MJF just SLS with different numbers?
The build-share arithmetic is shared, and it lives in one place so both processes compute it identically. But the agents, the refresh ratio, printhead wear and the time per millimetre are genuinely different, and they are separate settings, so an MJF quote is not an SLS quote with a discount applied.
Where do the agent costs appear?
In your cost, as a consumable line computed from the part’s volume and surface area at the usage rates you set and the price you pay per litre. The buyer sees material and production, never the agent arithmetic, because rates and costs stay out of the buyer’s breakdown.
Can I offer fast cooling as an option?
Not as a buyer’s choice yet. Cooling is a setting of the configuration: natural and fast cool-down each have their own duration per build, so a shorter cycle releases the build unit sooner and costs less machine time. Natural cooling is the quality default; a shop that wants to offer both can run a second configuration set to fast cooling.
How is SAF handled?
SAF uses the same build-share model as MJF, with its own machine and powder settings: build time per millimetre, refresh ratio and the consumables the machine really uses. Set the numbers to what your machine does, then calibrate the nesting efficiency from your own builds.
