• Easy to use. Intuitive controls and a user-friendly interface simplify operation for both beginners and experienced users alike.

Why Is a 180 °C Heated Chamber So Important?

1. An ambient temperature of 180 °C is the temperature required for annealing PEEK material.

Therefore, once the device has printed a PEEK model, it can be annealed directly inside the machine.

Advantages:

1. There is no need to remove the model from the build plate to avoid loss of adhesion between the bottom of the model and the plate — which would cause the internal stress of the lower model to lose its platform fixation, leading to deformation of the model's base after post-processing.
2. Avoid switching off and cooling the model in order to remove it. There is no exchange between hot and cold environments, which would cause the model to experience a large temperature differential in a short period of time, fixing the internal stress and making effective heat treatment impossible.
3. After printing, the annealing process can be configured directly within the printer without delay. For example, it can be pre-set to hold at 180 °C for 5 hours after printing, followed by 120 °C for 5 hours for complete annealing of PEEK parts.

2. 180 °C is the temperature at which PEI material can be printed to perfection.

1. Print environment temperature requirements: generally set between 160 °C and 200 °C to ensure the material can be fully extruded and adhered, and to reduce internal stress after moulding, preventing cracking. An ambient temperature of 180 °C is recommended to improve flowability, achieve greater bond strength between lines, and improve heat and chemical corrosion resistance by reducing moulding internal stress.
2. PEI has hygroscopic properties and can cause material degradation. The moisture content must be below 0.02%. Drying conditions are 150 °C for 4 hours; drying can be carried out directly within the chamber.
3. PEI materials also typically require post-moulding annealing to eliminate internal stress arising during the moulding process. The advantages of direct annealing are the same as for PEEK.

Why Is It So Difficult to Raise the Chamber Temperature to 180 °C?

With the benefit of prior knowledge, we know that a high-temperature chamber is a necessary condition for quality moulding of polymer materials such as PEEK and PEI. But why do large industrial machines struggle to reach a chamber temperature of 180 °C?

70–80 °C is the temperature limit for most printed circuit boards, motors, belts, and other components. Exceeding the ambient temperature will cause these parts to fail. This is why the cavity temperature of common printers is kept at this level.

120 °C is the temperature limit for high-temperature motors and belts. At the same time, they must be adequately cooled, shielded, and thermally insulated — or heat-dissipated for circuit components — along with thermal insulation for the cavity.

150 °C requires a fully independent enclosed chamber design and thermal insulation design. In addition to thermal shielding and heat dissipation design for all heat-resistant components, long-term durability and heat uniformity of the heating device are also required. A multi-layer thermal insulation design of the equipment housing is likewise necessary.

For an ambient temperature of 180–200 °C, an aerospace-grade thermal insulation protective cover is also required. The excellent aerospace thermal insulation material can completely isolate the air below and above the nozzle, as well as circulate and replace the hot air accumulated in the upper cavity with hot air from the housing under balanced pressure. This ensures that the exterior temperature of the housing meets safety standards for human use.

Ultra-High-Temperature Extruder System

Equipped with a dual-tooth silicon carbide extruder, it features high torque, exceptional wear resistance, and zero step loss. It can print all filaments at temperatures below 500 °C, including carbon fibre and glass fibre materials.

A water-cooling device is required — this is the key to smooth printing of high-temperature filaments. The hotend is an injection-moulded wear-resistant integrated nozzle that can be replaced in 30 seconds without removing any other parts or screws.

Thermally Uniform 200 °C Chamber

A specially designed baffle device allows hot air to circulate 360° within the cavity, ensuring uniform heating throughout, so that the polymer material model crystallises uniformly at any angle and achieves an ideal form.

Excellent Chamber Thermal Insulation and Safety

This professional-grade machine is the first to use an aerospace-grade thermal insulation protective cover. Thanks to its intelligent design, multi-channel heat dissipation, custom high-temperature-resistant components, and multi-layer thermal insulation materials, when the chamber temperature reaches 180 °C, the temperature of the front door, top door, screen, housing, and side panels remains within 40 °C — ensuring user safety.

200 °C High-Temperature Build Plate

• Aerospace-class ultra-flat build plate + polymer coating.
• Natural flatness of 0.05 mm.
• High-temperature flatness of 0.1 mm (chamber temperature 180 °C).
• No manual or automatic levelling required, avoiding manual levelling or sensor failure under high-temperature conditions.

All-in-One Annealing Function

After printing the model, there is no need to remove it from the build plate, cool it naturally, or anneal it in a separate annealing oven.

You can pre-select the "direct annealing after printing" function on the screen for the appropriate material, such as PEEK, PEI, etc. You can also adjust the built-in annealing temperature and time in the settings to achieve one-click annealing.
