PCL insufficient interlayer bonding
Problembeschreibung
PCL 3D printing has insufficient interlayer adhesion, delamination, collapse, and decreased mechanical properties.
Ursachenanalyse
PCL has a low melting point and slow cooling speed, prolonging interlayer bonding time; improper melt temperature; excessive printing speed; environmental temperature influence; insufficient interlayer diffusion.
Lösung
①Printing temperature optimization; ②Printing speed control; ③Environmental temperature management; ④Interlayer pressure or hot air assistance; ⑤Post-processing strengthening.；After adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Wichtigste Erkenntnis
Interlayer bonding in PCL 3D printing is the core of quality; balance of temperature and speed; auxiliary means improve bonding.；After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
