Capability Meets Creativity

CPAP High-Pressure Turbo Fan

With a wind (air flow) speed of 40,000 rpm that changes according to the printing speed of different parts; automatically adjusts the wind speed to ensure the cooling effect.

Motion Control Algorithm

self-developed delta structure control algorithm to improve printer speed

Binocular Structured Light System

○ Components：two high-definition camera and a micron-sized laser 

○ Function: Capture print details accurately—through the first layer detection, accuracy calibration, flow calibration

AI Detection

○ AI real-time detection and issue identification

○ The detection of debris and spaghetti 

Intelligent Zoned Heating

○ Precise heating control

○ Improvement of quality

Fully Automatic Levelling

With one-click the S1 will calibrate and adjust the bed level making getting thatperfect Z height simple and easy to master.

Vibration Compensation

With the S1 optimized algorithms, it will ensure print accuracy and avoid surface roughness and deformation.

Consumables Weighing

timely alerts when consumables (filaments) are running low.

Material Break Detection

Printing will be paused immediately when the consumable runs out, never destroying the part of the model that has already been printed and causing the print to fail.

Filament Drying

This unique function will ensure that the current filament are in a dry state during printing and the other is to dry any humid filament.
