AI Technical Summary

Technical Problem

At this stage, the forming temperature of FDM additive manufacturing technology is generally around 250℃, which is difficult to form high-performance engineering plastics with higher melting points, and it is easy to cause warping and deformation due to the fast cooling speed and poor interlayer bonding performance.

Method used

A 3D printing device with an insulation chamber was designed. Through the coordinated control of the temperature-controlled fan module, the insulation chamber heating layer and the forming platform, the printing consumables are formed at the optimal printing temperature, and the online heat treatment function is provided to avoid warping and deformation caused by excessive cooling speed.

Benefits of technology

It effectively solves the problem of difficult to form high-performance engineering plastics, optimizes the interlayer bonding performance, reduces the occurrence of warping and deformation, and reduces stress through online heat treatment, improving the performance of printed workpieces.
