Kings P440 SLS 3D Printer

High-Precision Printing with CO2 Laser

Overview

Experience a new generation of industrial 3D printing with the Kings SLS P440, designed for large-format production and maximum molding efficiency.

With an impressive 440 × 440 mm (XY) build area, the P440 delivers high-quality, detailed parts at scale. Its advanced temperature control and intelligent scanning path optimization ensure faster printing speeds, superior surface finish, and consistent accuracy across every build.

To keep your system always at its best, Kings3D offers lifetime free software and performance upgrades, ensuring your printer evolves with the latest innovations in SLS technology.

Advantages

The reuse rate of consumables is nearly 100%

With Kings3D’s original PA powder revival technology, the powder utilization rate approaches 100%—delivering exceptional sustainability without compromising performance. Every print maintains superior surface finish and strong mechanical integrity, ensuring consistent, high-quality results while minimizing material costs.

Ideal Applications

From medical applications to large prototypes, industrial parts, defense, and aerospace, the Kings SLS P440 delivers the reliability and precision demanded by the most advanced industries. Its versatility makes it the ideal choice for professionals seeking both performance and scalability.

The equipment utilization rate is nearly 100%

Thanks to optimized anti-oxidation technology for consumables, the Kings SLS P440 allows the completed build cylinder to be removed for independent cooling, while the next printing cycle can start immediately—even when the system remains at a high temperature. This innovative process significantly reduces cooling and warm-up times, improving productivity and lowering overall energy consumption.

The printer also features an external powder cylinder system, enabling automatic powder feeding and replenishment at any time during printing. This ensures continuous, uninterrupted operation and maximizes efficiency throughout long production runs.

Two-way intelligent powder spreading with double scrapers

The Kings SLS P440 is equipped with a multi-axis adjustable scraper, allowing fine-tuned calibration to ensure exceptional surface quality on all molded parts.

Its dual-direction powder supply and double-scraper system enable precise and uniform powder distribution, enhancing the stability of the temperature field while minimizing powder waste and spillage. The result is consistently smooth, high-quality prints with optimized material efficiency.
