PP FDM Warpage
Fenómeno do problema
【Problem Phenomenon】PP printed parts warp and have poor adhesion
Análise das causas
PP has large crystallization shrinkage and is prone to warpage and poor adhesion; open environment aggravates it; during on-site troubleshooting, verify item by item according to this mechanism to avoid blindly adjusting the machine based only on experience; this mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
Solução
Bed temperature 80-100°C; PP-specific adhesion; chamber insulation; brim; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability; change only one variable at a time and record parameter changes to facilitate locating effective measures
Conclusão principal
PP printing has the dual difficulties of warpage and adhesion, special glue plus insulation; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for similar problems in the future
