PBAT 3D printing application
Problem Phenomenon
PBAT 3D printing filament processing and printing quality, interlayer bonding and dimensional accuracy.
Cause Analysis
PBAT 3D printing temperature window; interlayer bonding; cooling rate; dimensional shrinkage; support structure.; when troubleshooting on site, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solution
①Optimize printing temperature; ②strengthen interlayer bonding; ③cooling control; ④dimensional compensation; ⑤support design.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
PBAT 3D printing is an emerging application; process parameters require fine management; verification ensures quality.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
