PP FDM Printing Temperature
Problem Phenomenon
[Problem Phenomenon] PP filament printing warps with poor adhesion; improper parameters
Cause Analysis
PP FDM nozzle 230-260°C, bed temperature 80-100°C; PP's crystallization shrinkage is large, easily warping with poor adhesion; dedicated adhesion needed (PP tape/glue stick)
Solution
Nozzle 230-260°C, bed temperature 80-100°C; PP-specific adhesion; chamber insulation to reduce warpage; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Key Takeaway
PP printing adhesion is the difficulty; dedicated 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 future problems
