PVDF Additive Manufacturing Interlayer Bonding
Sorun Belirtisi
【Problem Phenomenon】PVDF 3D printed parts have weak interlayer bonding, warpage and cracking, and low printing success rate
Neden Analizi
In FDM printing, if the extrusion temperature is too low, interlayer diffusion is insufficient and bonding is weak; higher temperature benefits bonding but dimensional accuracy decreases and there is HF release risk above 290℃; KTU research gives a 200-260℃ processing window
Çözüm
Take printing temperature values within 200-260℃ by weighing bonding strength against accuracy; control heat bed and environment temperature to reduce internal stress warpage; under no circumstances exceed 290℃ to prevent HF
Temel Çıkarım
The PVDF printing window is 200-260℃, with interlayer strength and accuracy trading off against each other; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
