Chamber thermal insulation/safety

For the first time, an aviation-grade heat-insulating sports protective cover is used in professional-grade 3d printer.

Through clever design, multi-path heat dissipation, customized high-temperature resistant parts, and the use of multi-layer heat-insulating materials, when the chamber temperature reaches 180°C, the temperature of the front door, top door, screen area, body, and side panel area of the machine is within 40°C, ensuring the safety of users.

200°C thermally uniform chamber

High temperature platform 200°C

• Aviation-grade ultra-flat platform + polymer-based coating
• Natural flatness 0.05mm
• High temperature flatness 0.1mm (cavity temperature 180°C)
• No manual or automatic leveling required, avoiding manual leveling or sensor failure in high temperature environments

One-stop annealing function

After the model is printed, there is no need to peel the model from the platform, cool it naturally, or anneal it in the annealing furnace.

You can select the “direct annealing after printing” function for the corresponding material such as PEEK, PEI, etc. on the screen in advance. You can also modify the built-in annealing temperature and time in the settings to achieve one-click annealing.

Why is a 180°C and above heated chamber important?

②180°C is the temperature at which PEI material can be perfectly printed.

• (1)Printing environment temperature requirements: Usually set between 160°C and 200°C to ensure that the material can be fully extruded and bonded and reduce the internal stress after molding to prevent cracking. The recommended ambient temperature is 180°C to improve fluidity, obtain higher combined line strength, and improve heat resistance and chemical corrosion resistance by reducing molding internal stress.
• (2)PEI has hygroscopic properties and can cause material degradation. The humidity value is required to be less than 0.02%. The drying conditions are 150°C and 4 hours of drying treatment, and the drying treatment can be carried out directly in the cavity.
• (3)PEI materials also usually need to be annealed after molding to eliminate the internal stress generated during the molding process. The advantages of direct annealing are the same as PEEK.

Why has it previously been so difficult for 3D printers to raise the internal build chamber temperature to 180°C and above?

Through the previous knowledge popularization, we know that a high-temperature build chamber is a necessary condition for good molding of polymer materials such as PEEK and PEI, but why can’t the build chamber temperature of many other large industrial-grade 3d printers reach 180°C+?

70-80°C is the temperature limit of most circuit boards, motors, belts and other parts. Exceeding this ambient temperature will cause these parts to break down. Therefore, the temperature of ordinary printers with cavity temperature is at this level.

120°C is the temperature limit of high-temperature motors and belts. At the same time, they need to be well cooled, shielded and heat-insulated or heat-dissipated for circuit parts, and heat-insulated for the cavity.

150°C requires a completely independent cavity closure design and heat-insulation design. In addition to the heat screen and heat-dissipation design for all heat-resistant parts, the long-term durability and heat uniformity of the heating device is also required and the multi-layer heat insulation design of the equipment shell.

For an ambient temperature of 180°C-200°C, an aviation-grade heat-insulating sports protective cover is also required.

The excellent sports heat-insulating material can completely isolate the air below and above the nozzle, and circulate and replace the hot air gathered in the upper cavity with the hot air in the shell under balanced pressure. Ensure that the external temperature of the shell meets the safety standards for human use.
