Kings3D KSPA12BK Black SLS Nylon Powder – Tough Impact-Resistant Parts | PA12, 10 kg
$750
What your process engineer actually checks
Toughness you can design around
With 38 kJ/m² Charpy impact and 20% elongation at break, KSPA12BK is the black PA12 grade for snap-fits, clips, and functional parts that must flex and take impact without cracking — durable end-use hardware rather than brittle models.
A materials engineer on the line
Questions on sinter settings, refresh ratio, or part durability? 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 KSPA12BK is a black PA12 (nylon-12) laser-sintering powder for tough, impact-resistant end-use parts — a durable functional grade with near-100% powder reusability. It runs on Kings and other open PA12 SLS systems with fiber or CO₂ lasers, and we supply it from US stock with the starting parameters to run it.
Why engineers choose KSPA12BK
A tough black nylon-12 powder with production-ready mechanical numbers.
Tough and impact-resistant
38 kJ/m² Charpy impact, 7.5 kJ/m² notched, and 20% elongation at break — black PA12 that survives snap-fits, clips and drops instead of cracking.
Durable functional parts
46 MPa tensile, 50 MPa flexural, 1600 MPa tensile modulus — a chemical- and abrasion-resistant nylon for jigs, housings and end-use hardware, not display models.
Near-100% powder reuse
A narrow 50 µm particle distribution and stable melt behaviour let unsintered black powder recover cleanly build after build, keeping cost-per-part low.
Runs on open SLS systems
Melting at 187 °C, KSPA12BK works with fiber or CO₂ lasers — compatible with Kings SLS (P440) and other open PA12 SLS platforms, with 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
KSPA12BK ships from our Los Angeles warehouse in 1–2 business days, sealed with a batch data sheet, plus starting sinter parameters for common PA12 SLS platforms.
