Nine nylons,
every number from our own datasheet.

Not "contact us for specifications." This is the complete material line-up Primofort runs across SLS and MJF, transcribed straight from our printed material datasheet — tensile, flexural, modulus, elongation, heat deflection and build size, for all nine.

9 production nylons up to 910 × 430 × 400 mm^CONFIRM 2 imported / domestic tiers 1 biocompatible white PA 12

Three standouts

Capabilities most buyers do not know we have.

Every material below is genuinely in production. These three open doors that the current site barely mentions.

Large format

910 × 430 × 400 mm^CONFIRM

FS-YC3201 tough Nylon 12, printed on our large-format floor. Single-piece parts most bureaus would have to cut and bond. This envelope is Primofort's own operating limit, not a figure Farsoon publishes.

Biocompatible

YP120 white PA 12

Bright-white, biocompatible Nylon 12 — YF's own datasheet states biocompatible, which opens wearables and medical-adjacent models. We say biocompatible, not "skin-safe" — that would overstate what the datasheet supports.

Carbon fibre

110 MPa / 10.0 GPa

FS-YC6130CF carbon-fibre Nylon 6 — 110 MPa tensile strength and 10.0 GPa tensile modulus, stiffness in metal-replacement territory at nylon weight.

The complete datasheet

All nine nylons, every mechanical property.

Transcribed cell by cell from Primofort's printed material datasheet. Modulus figures are converted from the datasheet's MPa to GPa for readability — the datasheet value is the same number, just rescaled (1,000 MPa = 1 GPa).

Manufacturer/YF-published figures from Primofort's printed material datasheet. Modulus columns rescaled from the datasheet's MPa figures to GPa (1,000 MPa = 1 GPa); no value is rounded beyond the datasheet's own decimal places. "Imported" materials (Formlabs, YP120, YP120GF) and "domestic" materials (FS-YC series) are both genuinely in production — ask at quote which tier fits your budget and application.

How to choose

Which nylon fits your part?

Five common use cases, matched to the material that actually wins on that property — not just a guess.

FYC110

Most flexible / toughest

40% elongation at break — the highest on this sheet. Best for hinges, clips and parts that need to bend and spring back without cracking.

FS-YC6140GF

Stiffest

4.8 GPa flexural modulus and 110 MPa flexural strength — the least flex under load of any material here. Good for structural brackets and jigs.

FS-YC6130CF

Highest tensile strength

110 MPa tensile / 10.0 GPa tensile modulus — carbon-fibre Nylon 6, for parts that replace metal and need to survive real pulling loads.

FS-YC3201

Largest single piece

Build size up to 910 × 430 × 400 mm^CONFIRM — printed whole instead of split and bonded across multiple parts.

YP120

Medical-adjacent

Bright-white PA 12, biocompatible per our datasheet — for wearables and medical-adjacent models. Biocompatible is not the same claim as a medical-device certification; ask us for the exact scope before you rely on it.
