← ScienceWhich consequence rapidly degrades 3D printer resin when exposed to unexpected laser intensity?
A)Excessive crosslinking happens throughout material✓
B)Thermal expansion bends the printing platform
C)Viscosity sharply drops reducing resolution
D)Polymer chains crystallize causing opacity
💡 Explanation
Excessive laser intensity yields overcuring because photoinitiation occurs far beyond design limits, therefore widespread crosslinking occurs throughout the entire volume rather than localized curing, because less initiator is not activated everywhere simultaneously
