Advantages of IEMAI LF YM-NT-1200

• Working area for large products. The build volume allows for models up to 1200 mm on each axis.
• Two independent IDEX nozzles. Each nozzle moves separately, and the system has calibration of the distance between nozzles along the XYZ axes. The design includes two modular nozzles.
• Temperature system for technical polymers. The standard nozzle temperature is 350 °C, with an optional limit of 450 °C. The platform heats up to 120 °C, and the chamber and filament box up to 60 °C.
• Productive extrusion. The maximum print speed is 200 mm/s, with acceleration of 10000 mm/s². A flow rate of 60 mm³/s is specified for a 0.6 mm nozzle, speed of 100 mm/s, and PLA.
• Working with various materials. The 3D printer supports common engineering plastics, materials with carbon or glass fiber, modified polymers, and support printing materials. It uses 1.75 mm diameter filament.
• Automatic control functions. The model has power outage recovery, filament end sensor, automatic leveling, and automatic shutdown.
• Local and cloud management. Data transfer is available via Ethernet, USB, and Wi-Fi.

Extrusion System and Nozzles

The IEMAI LF YM-NT-1200 3D printer has two modular nozzles with independent IDEX movement. The standard nozzle diameter is 0.6 mm, with a 0.4 mm option available. The nozzle material is hardened steel. The extrusion system cooling is air-based. The recommended layer thickness is 0.05–0.3 mm.

The maximum print speed is 200 mm/s, with acceleration of 10000 mm/s². A flow rate of 60 mm³/s is specified for PLA at a speed of 100 mm/s and a 0.6 mm nozzle. The page also indicates synchronous control of material feeders and calibration of the distance between two nozzles along the XYZ axes.

Temperature Modes and Platform

The printer's nozzle in standard configuration heats up to 350 °C, and the platform with magnetic fixation and PEI coating up to 120 °C. The working chamber and filament box support heating up to 60 °C. Thanks to automatic PID tuning, the temperature is maintained with high stability within ±2 °C.

3D Printing Process Management

The model is equipped with a 10.1-inch color touchscreen with a resolution of 1280 × 800 pixels. The RAM is 2 GB, and the internal flash storage is 32 GB. The processes are managed by an eight-core logic controller RK3576 with Arm Cortex-A72 cores at 2.2 GHz and Arm Cortex-A53 at 1.8 GHz, while the precision of movements is ensured by an STM32 ARM Cortex-M4 processor at 168 MHz.

Thanks to this hardware platform, a wide range of automatic functions is implemented: platform leveling, filament end detection, print recovery after power failure, automatic shutdown, and synchronous feeder control. Calibration of the distance between nozzles, PID temperature regulation, work with a magnetic platform, and remote cloud OTA updates are also supported.

Materials for 3D Printing

The printer works with thermoplastic filament with a diameter of 1.75 mm. Compatible materials are divided into five groups.

• Carbon fiber reinforced: CF-PPS, CF-PPA, CF-PAHT, CF-PA12, CF-PA6, CF-PC, CF-PET, CF-ABS, CF-ASA, CF-PETG, CF-PP, CF-PLA.
• Glass fiber reinforced: GF-PPS, GF-PPA, GF-PAHT, GF-PA12, GF-PA6, GF-PC, GF-PET, GF-ABS, GF-ASA, GF-PETG, GF-PP, GF-PLA.
