Sheet 01 — part envelope check

Will your part
fit in one piece?

Most bureaus make you email them to find out. Type the size of your part and see the answer now — every build envelope we run, and which nylons each one gives you.

Every envelope we run

Seven build envelopes. No guessing which one you get.

These are the build sizes behind Primofort's published material list — the same figures that appear on the materials page. Nothing here is a machine we don't own, and nothing is rounded up.

160 × 160 × 300SLS · powder bed

Formlabs Fuse platform

Nylon 11, Nylon 12 and glass-filled Nylon 12. The workhorse for prototypes and small batches.

—

380 × 284 × 380MJF · HP Jet Fusion

HP Multi Jet Fusion

HP-certified PA 12, with HP's own per-material tolerance tables behind it. Best for repeatable batches.

—

420 × 350 × 350SLS · reinforced

High-strength nylon chamber

Nylon 6 with glass or carbon fibre — the stiffest material we run, at nylon weight.

—

420 × 420 × 450SLS · white PA 12

Bright-white & biocompatible

YP120 and YP120GF. Bright-white biocompatible nylon for wearables and medical models.

—

375 × 375 × 500SLS · tall parts

Tall-format chamber

Fibre-filled Nylon 12. The one to reach for when height is the problem, not footprint.

—

910 × 430 × 400^CONFIRMSLS · large format

Large-format SLS

Tough Nylon 12, and the reason to call us instead of a bureau that would cut your housing in half. Figure taken from Primofort's own material datasheet, still being confirmed as in service.

—

1,174 cm² × 190PolyJet · full colour

Stratasys J-series^CONFIRM

Full-colour, multi-material resin on a tray rather than a rectangular box — footprint area is the limit, so fit is confirmed by an engineer.

What that leaves you

The nylons your part can be made from.

Filtered live to the envelopes that fit. Published datasheet figures — the same ones on the materials page, not marketing rounding.

Manufacturer-published figures from Primofort's material datasheet. HP publishes its own tables for MJF. Full flexural data and downloads live on the materials page. Tolerance for your specific geometry is confirmed at quote.

If nothing fits whole

Send it anyway. An engineer will look at the geometry and tell you where it could be split, or whether it is simply the wrong process for that part. We would rather say so than take the order.

Fitting is not the same as printing well

Flat parts over about 180 mm across with walls under 3 mm warp — our own SLS design guidance covers wall thickness, escape holes and orientation. The checker answers geometry, not design.

Why we publish this at all

Because the alternative is you emailing four bureaus and waiting. If your part does not fit here, you have lost thirty seconds instead of three days.

Proof, not promises

These envelopes are on our own floor.

Primofort is the factory, not a broker. Every photo below was taken in our climate-controlled production hall in Dongguan — the machines that would print your part.
