// nesting + costing for additive production

Every build, fully packed and priced to the part.

BuildFill nests your parts in 3D with the manufacturer's gaps, works out real build times, and prices every part from your own rates. For SLS, MJF, MJP, SLA and FDM.

How it works

STEP 01

Upload

STL, 3MF or OBJ — one part or a whole order. You can also forward the customer's email with the models attached.

STEP 02

Nest

Parts are packed in layers and inside each other, as low in the chamber as possible. Gaps and wall margins never go below the manufacturer's rule.

STEP 03

Quote

Build hours, material and your rates become a price for every part — with a 3MF build file and a quote PDF.

One engine, five technologies

SLS · MJF3D packing, density rule, powder refresh. A warning when the last build is nearly empty but still costs a full cycle.
MJPSingle layer or stacked — the layout that uses the least support wax, with the faster one shown next to it.
SLA · FDMSlicer-accurate time and material for each part, plate layout and a per-part price.
Your shopYour machines, materials, hourly rates, taxes and margin. Change anything by typing it — the built-in assistant updates the numbers.

The example above: 179 L-brackets on an HP Jet Fusion 5200 in one build, nested by BuildFill with HP's recommended gaps.

Questions

Does BuildFill print parts?

No. BuildFill is software. It calculates layouts and prices; printing is done by you, on your machines.

Which file formats are supported?

STL, 3MF and OBJ. Build layouts are exported as 3MF with every copy placed.

Can I use my own prices and rules?

Yes. Rates, materials, taxes and margin are yours. Gaps can be increased above the manufacturer's minimum, never reduced below it.

What happens to my files?

Uploaded models and calculation data are deleted automatically after 24 hours. See the Privacy Policy.

How do I cancel?

In your account, at any time. You keep access until the end of the paid period. See Refunds.
