Kings3D KSPA12GB Glass-Bead PA12 SLS Nylon Powder – Stiff, Heat-Resistant Parts | 150 °C Vicat, 10 kg
$750
What your process engineer actually checks
Stiffness and heat you can design around
With 40% glass beads, KSPA12GB reaches a 3000 MPa tensile modulus and a 150 °C Vicat softening point — well above unfilled PA12. It is the grade to reach for on stiff jigs, fixtures, and thermally-loaded parts that must hold their shape under load and warmth.
A materials engineer on the line
Questions on chamber temperature, part packing, or heat performance? We run a production SLS print center in-house, so our engineers answer from real build experience — not a script. Sub-4h reply, NDA standard.
Kings3D KSPA12GB is a PA12 nylon powder filled with 40% glass beads — the stiff, dimensionally stable, higher-heat grade for SLS. The glass reinforcement lifts modulus and Vicat softening well above unfilled PA12, so parts hold shape under load and warmth. It runs on Kings and other open glass-filled PA12 SLS systems, and we supply it from US stock with starting parameters.
Why engineers choose KSPA12GB
A glass-filled PA12 with production-ready stiffness and heat numbers.
40% glass-bead reinforcement
Glass beads stiffen the PA12 matrix to 3000 MPa tensile modulus and cut warpage — the reason to pick KSPA12GB over unfilled nylon for parts that must stay flat and true.
Higher heat resistance
150 °C Vicat softening and a 187 °C melting point give more thermal headroom than standard PA12 — parts keep their shape near warm air, motors, and enclosures.
Strong and rigid
46 MPa tensile, 70 MPa flexural, 2800 MPa flexural modulus and 36 kJ/m² Charpy impact — an engineering nylon for functional parts, not just concept models.
Runs across open SLS platforms
A 50 µm D50 powder that sinters on Kings SLS P440 Pro and P260 Pro and other open glass-filled PA12 SLS systems — laser and chamber parameters tuned per machine.
How we supply it
A production print center supplying proven powders — not a warehouse reselling boxes.
Proven, then stocked
We run a production SLS print center in-house. We only stock powders we have printed and validated ourselves — so what ships is a known quantity, not a catalog listing.
Stocked in California
KSPA12GB ships from our Los Angeles warehouse in 1–2 business days, sealed with a batch data sheet, plus starting laser and chamber parameters for common SLS platforms.
Custom formulation on request
Need a different fill fraction, colour, or a nylon tuned to a specific stiffness or temperature target? Tell us the goal and we will discuss a custom SLS powder option with our material partners.
