HP Nylon PA12 — MJF 3D printing

MJF Available Express available

Production-grade nylon from HP Multi Jet Fusion — dense, tough and consistent at volume.

HP Nylon PA12 3D printing material

HP's Multi Jet Fusion PA12 is a workhorse production nylon: no support structures, near-isotropic mechanicals and an excellent cost-per-part at batch volume. Parts come out grey and are typically dyed black. It is tough, chemically resistant and dimensionally consistent across a full build.

What HP Nylon PA12 is used for

MJF nylon PA12 is a true end-use production material. It is used for clips, ducting, housings, complex assemblies and enclosures — the sort of durable black plastic parts found inside consumer and industrial products.

Strengths

  • No support structures — internal and interlocking geometry prints freely
  • Dense, smooth parts with near-isotropic, production-grade mechanicals
  • Best cost-per-part of any production polymer at batch volume
  • Good chemical resistance to oils, greases and hydrocarbons

Know the limits

  • Ships grey — dyed black is the standard finish
  • Colour choice essentially ends at black
  • Slightly porous until sealed

Maximum build size

380 × 380 × 280 mm

Surface finish & colours

Clean, consistent matte grey off the machine; dyes black evenly and can be chemically smoothed.

Available grey as-printed or dyed black, per process.

Finishing & post-processing for HP Nylon PA12

Parts printed in HP Nylon PA12 in MJF can be finished a number of ways at KAD3D, from a clean functional surface to a fully painted, display-ready result. The treatments below are the ones we most often apply to this material.

Dyeing
The part is bath-dyed to a uniform through-colour, most effective on light or natural material and excellent for consistent black finishes.
Bead Blast
Fine media is blasted across the surface for an even, matte, uniform texture that removes powder and tooling marks.
Chemical Smoothing
A chemical process melts the surface smooth for a sealed, injection-moulded-like finish that also improves water resistance.
Sealing
A clear sealer closes surface porosity so the part resists moisture and is easier to clean — important on powder and colour parts.

What this material supports

✓ Paintable ✓ Threaded inserts
  • Paint & custom colour: HP Nylon PA12 primes and paints well, so parts can be matched to any brand colour, gloss level or metallic look.
  • Threaded inserts: heat-set or press-fit brass inserts can be installed for durable, re-usable metal threads for fasteners.

Most popular finish: Bead-blast and dye black for the standard production finish.

Reference #3DBenchy — like-for-like pricing

To make material costs easy to compare, KAD3D prints the same standard model — the #3DBenchy — in every material. The price shown is what that identical benchmark part costs in HP Nylon PA12, so you can weigh materials against each other on a genuine like-for-like basis before uploading your own file.

These prices were taken on 1 July 2026 and are still in place.

Where it fits

Bridge production, connectors, housings, ducting and brackets, from one to thousands of parts.

Well suited to mining-duty and automotive components for operations across Western Australia and Queensland, where its toughness, chemical resistance and low cost-per-part at volume make short production runs viable without tooling.

Behaves close to injection-moulded nylon without the tooling.
