Kings P440 SLS 3D Printer: Selective Laser Sintering for Industrial Applications
What your process engineering lead actually checks
Supported by the team that runs it
We run AO Metal and partner systems daily for our own print services, so install, training, and first builds are handled by engineers who actually operate the machine. When you call support, you reach the team that qualified it.
An applications engineer on the line
Questions on build volume, laser config, throughput, or material compatibility? A named applications engineer scopes it directly — not a sales rep. 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.
