PEEK Printing Platform Adhesion and Warpage
Problem Phenomenon
【Problem Phenomenon】PEEK printed parts have poor first-layer adhesion, and corners warp and detach from the platform
Cause Analysis
PEEK is semi-crystalline with large shrinkage; a cold platform has insufficient adhesion and uneven cooling causes warpage; a bed temperature of about 100℃ combined with a special fixing agent can improve adhesion; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solution
Heat the platform to 100℃ and use special adhesives such as DimaFix; enclose the chamber to reduce ambient temperature difference; slow down and thicken the first layer and optimize the model placement orientation
Key Takeaway
Printing adhesion relies on a heated bed plus a special agent; chamber insulation simultaneously prevents warpage; 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
