ABS FDM adhesion and warpage
Fenómeno do problema
[Problem phenomenon] ABS printed parts have corners lifting off the platform, severe for large parts
Análise das causas
ABS shrinkage is about 0.4-0.7% but cooling stress is large and prone to warpage; heated bed plus adhesion aids (slurry, tape) and chamber heat preservation are the three major countermeasures; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blind machine adjustment based solely on experience
Solução
Level the platform and use adhesion agent; add brim; chamber heat preservation; reduce printing speed for large parts; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Conclusão principal
ABS printing warpage is solved by the three moves of leveling, adhesion and chamber; 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 subsequent similar problems
