PP FDM Warpage
Fenómeno del problema
【Problem Phenomenon】PP printed parts warp and have poor adhesion
Análisis de la causa
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
Solución
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
Conclusión clave
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
