Kings P440 SLS 3D Printer: Selective Laser Sintering for Industrial Applications
What your process engineer actually checks
Locked, traceable lot chemistry
Every lot ships with a COA documenting PSD, sphericity, flow rate, apparent density, and full chemistry — and a lot number you can trace. Aerospace and medical teams reorder 4+ times without re-qualifying.
Qualified parameters, not just powder
Validated parameter sets for EOS M 290, Renishaw 500Q, SLM 280, and our own AO Metal LPBF ship with the order. Load the profile and hit density on the first build — no parameter-development burn.
A materials engineer on the line
Questions on ferrite content, flowability, recyclate ratios, or HIP response? A materials engineer answers directly — not a contact-form bot. Most replies in under 4 hours, NDA standard.
main features
The Kings P440 SLS 3D Printer is a powerful and efficient Selective Laser Sintering (SLS) 3D printer designed for industrial-grade applications. With its large printing size, high molding efficiency, and user-friendly software, this SLS laser 3D printer ensures superior performance and precision for various industries.
High-Speed Laser Sintering: Optimized scanning and heating systems allow up to 5KG to be printed within 24 hours. The beam size (>0.28 mm) enhances printing speed, while a variable beam size improves printing precision.
“>”>High-speed Laser Sintering
- Optimized scanning and heating system 5KG can be printed within 24h.
- Beam size >0.28 mm: beam size relate to printing soeed and variable beam relate to printing precision.
- 8-zone independent temperature zone control.
External powder
cylinder Supply
Save cost: The main machine can be smaller, better structure, easy maintenance, and cost saving.
Continuous supply: With continuously supplying powder to the machine, it simplifiesoperations and ensures continuous production.
One Powder cylinder can supply two machines: It simplifies factory layout for management and mass production.
Dual-scraper two-way intelligent powder supply
Dual-scraper two- way intelligent powder supply VS Roller powder supply.
Better printing surface: The powder bed will be pressed by roller , which may cause details blurring.
High consistency for precision and strength: It will cause higher deformation in the center and corner of thepowderbed for Roller powder supply.
High efficiency: Dual-scraper two-way intelligent powder supply is more efficient thanRoller powder supply.
self developed software
100% compatible with our own machine to reach best performance
User-friendly with customized languages supported EN,DE,SP,FR,CNetc.
Free updating, rich data packs for different application and industry
self developed materials
Material is 100% compatible with SLS machine, which will ensure better precision, stability, and accuracy.
Econimic and cost-effective.
1. It is 100% produced by Kings, price much less than other OEMbrands.
2. It makes the re-use rate close to 100%. 20% fresh powder and 80% used powder.
Production capacity reaches 15,00kg/day. It also performs well inEOSand many other models. The high performance is approvedbydomestic customers.
GFPA1200BK nylon powder (black). Black nylon powder with a particle size D50 of about 50 microns and a narrow and uniform distribution. It can be sintered using fiber laser or carbon dioxide laser, and the powder has high sphericity and extremely high fluidity.
GFPA12GB glass fiber reinforced nylon powder (blue gray). Excellent transparency. Excellent humidity and moisture resistance. Fast to build and easy to finish. Accurate and dimensionally stable.
GFPA1200 nylon powder (white). Nylon powder with high sphericity and fluidity. Maintain color stability in repeated use.

Full documentation — TDS, SDS, batch COA, and parameter sets for the major LPBF platforms. Everything you need for qualification under AS9100 / ISO 13485 workflows.
We atomize our own. Custom variants on request.
Tighter PSD, modified chemistry, custom blend? Our ATO atomization lab runs custom batches in 3–4 weeks. Biocompatible, refractory, proprietary — all in-house, verified before ship.
Complete the workflow
What teams add to an order so the first build runs clean — handling, plates, and a sample to qualify before you commit volume.
From process engineers running Kings P440 SLS 3D Printer: Selective Laser Sintering for Industrial Applications
Unedited feedback from customers who reorder Kings P440 SLS 3D Printer: Selective Laser Sintering for Industrial Applications.
Same lot 4 times in a row. We stopped re-running parameter sweeps after the second order — density was identical to the first build.
Asked about ferrite content on a Friday. A materials engineer answered Monday morning with actual data, not a sales pitch. That's why we keep ordering.
COA matches the bottle. PSD and flow are exactly what was on the sheet — we run it on a Renishaw 500Q and it hits density on the first try.
