Applications of 3D Printing Vacuum Furnace

The ZYLAB 3D Printing Vacuum Furnace is specially designed for the post-processing of metal and ceramic 3D printed components. It is ideal for:

• Stress relief annealing to eliminate internal stress and prevent deformation or cracking.

• Alloy homogenization and diffusion under high-temperature vacuum or inert atmospheres.

• High-temperature sintering of ceramic parts to enhance density and mechanical strength.

• Atmosphere-protected sintering (e.g., nitrogen or hydrogen) to control phase transitions and prevent oxidation.

• Thermal treatment of high-temperature alloys and composite materials, including carbon fiber-reinforced parts.

Precautions for Using

1. Pressure Limit:
   During operation, the internal pressure of the quartz tube must not exceed 0.15 MPa (absolute pressure) to prevent equipment damage due to overpressure.

2. Temperature Limit Under Vacuum:
   When operating under vacuum, the maximum working temperature should not exceed 1000°C.

3. Gas Supply Regulation:
   Gas cylinders typically have high internal pressure. A pressure regulator must be installed when introducing gas into the furnace tube. It is recommended to use a low-pressure regulator for laboratory use with a range of 0.01 MPa to 0.15 MPa (gauge pressure) for greater safety and precision.

4. Vacuum Restrictions Above 1000°C:
   When the furnace temperature exceeds 1000°C, the quartz tube must not be under vacuum. The internal pressure should be kept at atmospheric pressure to avoid damage to the quartz chamber.

5. Maximum Operating Temperature at Atmospheric Pressure:
   For long-term use at atmospheric pressure, the maximum safe temperature for the high-purity quartz tube is ≤1150°C.

6. Exhaust During Heating:
   The exhaust valve should be opened during heating and sintering to prevent pressure buildup inside the chamber. If the exhaust valve must be closed during heating, monitor the pressure gauge constantly. If the absolute pressure drops below 0.05 MPa (vacuum) or rises above 0.15 MPa (positive pressure), the exhaust valve must be opened immediately to prevent chamber rupture.

7. Cooling System Requirement:
   A water chiller must be connected before conducting high-temperature sintering to prevent the high-temperature silicone sealing rings from melting.

8. Material Caution:
   Avoid sintering materials containing alkaline ions, as these may cause devitrification or damage to the quartz chamber.
