Iemai HT SPAC-HT-920 3D Printer

Large-Format High-Temperature 3D Printing with Structural Polymers

Iemai HT SPAC-HT-920 is an industrial-grade high-temperature 3D printer designed for manufacturing large-scale parts from highly heat-resistant and high-melting polymers such as PEEK, PEKK, PEI (Ultem), and PPSU. The model features a large build area of 900 × 900 × 1000 mm, a dual-nozzle system with nozzle heating up to 500 °C, platform heating up to 180 °C, and a thermostatic chamber with temperatures up to 150 °C. The 3D printer operates with a 1.75 mm filament, is equipped with an enclosed body, and supports automatic leveling and 3D printing control systems.

Main Advantages of IEMAI HT SPAC-HT-920

• Large-format build area. The build volume of 900 × 900 × 1000 mm allows for the production of large solid parts and large-scale functional blocks without splitting the model into parts.
• Thermal chamber with heating up to 150 °C. The working chamber maintains a stable temperature regime, preventing shrinkage, deformation, and delamination between layers when printing PEEK, PEKK, and Ultem.
• Dual extrusion system up to 500 °C. Two liquid-cooled nozzles allow for the combination of the main material and auxiliary breakaway or soluble support structures.
• High-temperature platform up to 180 °C. Rapid heating of the working surface ensures strong adhesion of the first layer with heat-resistant engineering plastics.
• Filament drying and box up to 70 °C. The built-in material compartment protects hygroscopic thermoplastics from moisture absorption during prolonged printing.
• Automatic control systems. The model features print recovery after power failure, filament end detection, automatic platform leveling, and automatic shutdown.
• Network interfaces and cloud management. Connectivity options via Ethernet, USB, and Wi-Fi simplify remote monitoring and software updates.

Extrusion System and Nozzles

The IEMAI HT SPAC-HT-920 3D printer is equipped with a dual extrusion system with water cooling. The maximum nozzle heating temperature is 500 °C. The standard nozzle diameter is 0.6 mm, with additional options of 0.4 mm, 0.8 mm, and 1.0 mm available. The nozzles are made of hardened steel for resistance to abrasive and high-temperature filaments.

The positioning accuracy on the X/Y axes is 0.0125 mm, and on the Z axis is 0.00125 mm. The recommended layer thickness ranges from 0.05 to 0.4 mm, and the maximum 3D printing speed reaches 150 mm/s.

Temperature Modes and Platform

The printer's working chamber is a fully enclosed design with forced hot air convection up to 150 °C. The extruders heat up to 500 °C, and the platform surface up to 180 °C. The material storage compartment supports filament drying at temperatures up to 70 °C.

The 3D printing platform is equipped with a magnetic or vacuum fixation system for removable plates, simplifying the removal of finished large-scale parts. Temperature parameters are controlled by PID regulators with an accuracy of ±2 °C.

3D Printing Process Management

Management is carried out via a 10.1-inch color touch display. An industrial controller running Linux processes complex controlled trajectories and ensures a stable 3D printing process.

Control functions include multi-point automatic platform leveling, material presence sensors, a system for resuming work after a power outage, and power management.

Materials for 3D Printing

The IEMAI HT SPAC-HT-920 works with 1.75 mm diameter filament. Compatible polymers are divided into the following groups:

• Superstructural polymers: PEEK, PEKK, PEI 1010 / PEI 9085 (Ultem), PPSU, PSU.
• Reinforced composites: CF-PEEK, GF-PEEK, CF-PEI, CF-PA, GF-PA.
• Structural plastics: PA6, PA12, PC, ABS, ASA, PETG.
• Standard thermoplastics: PLA, TPU, PVA.
• Support materials: ThermaX HTS, E-Water, E-Remove, and breakaway materials.

Applications of IEMAI HT SPAC-HT-920

Thanks to the combination of a 900 × 900 × 1000 mm working area and high printing temperatures, the device is used in the following areas:

• aerospace and aviation industry, manufacturing of large-scale heat-resistant assemblies;
• defense and automotive industry, production of strong body-like elements;
• manufacturing of forming equipment, molds, and technological jigs;
• small-scale production of parts from high-melting plastics instead of metal counterparts;
• 3D printing of large-scale models and functional prototypes from PEEK and PEI.

Compatibility and Connectivity

For preparing 3D printing programs, IEMAI 3D SLICER, Cura, Simplify3D, PrusaSlicer, and OrcaSlicer slicers are used. The printer accepts STL, OBJ, STP/STEP, 3MF, and G-code formats.

Data transmission is carried out via USB, Ethernet, or Wi-Fi interfaces. 64-bit versions of Windows 10/11, Linux, and macOS are suitable for PC operation.

Tips for Working with IEMAI HT SPAC-HT-920

• Before starting 3D printing with PEEK, PEI, or PEKK polymers, preheat the chamber to 130–150 °C for 45–60 minutes.
• Keep hygroscopic filaments in a heated box at up to 70 °C throughout the entire manufacturing cycle.
• Monitor the circulation and fluid level in the external or built-in water cooling system.
• Select adhesives and platform coatings according to the recommended types for specific thermoplastics.
• Run automatic platform leveling after it has fully heated to the working temperature.
• Clean the nozzles with special technical compounds immediately after finishing work with high-melting materials.
