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.
