ABS FDM warpage
Problem Phenomenon
[Problem Phenomenon] ABS printed part warpage and layer cracking
Cause Analysis
Shrinkage and uneven cooling internal stress; open environment with large temperature difference; during on-site troubleshooting, verify item by item according to this mechanism, avoid blindly adjusting the machine based only on experience; this mechanism has been repeatedly verified by industry materials and should be confirmed first during troubleshooting
Solution
Enclosed chamber; bed temperature 100-110℃; adhesive brim; after adjustment, continuously sample to verify the effect, resume mass production only after confirming stability; change only one variable each time and record parameter changes to facilitate locating effective measures
Key Takeaway
ABS printing warpage relies on chamber, heated bed, and adhesion; 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 later
