AI Technical Summary

Technical Problem

Carbon fiber reinforced polyphenylene sulfide 3D printing materials are prone to nozzle filament snagging and die head accumulation during fused deposition modeling. Furthermore, existing improvement methods can easily damage the conductive network, leading to unstable antistatic properties. A single lubricant or process adjustment cannot simultaneously address both melt processability and mechanical properties.

Method used

By employing a specific ratio of silicone and TPSiV elastomer compound modification technology, silicone acts as an interfacial lubricant, migrating at the interface between the melt and the nozzle to form a lubricating isolation film, while TPSiV elastomer improves the melt fracture behavior. The two work synergistically to solve the material accumulation problem and maintain the integrity of the conductive network.

Benefits of technology

It effectively reduces the adhesion between the melt and the nozzle, avoids wire snagging and material accumulation, maintains stable antistatic properties, broadens the printing process window, improves printing success rate, and enhances the toughness and strength of the material.
