Which consequence results when a laser engraver's beam defocuses?

💡 Explanation

Increased thermal stress occurs upon defocusing, because the lowered energy density causes slower material removal. The thermal conduction mechanism heats a larger volume; therefore stress concentrates rather than ablating perfectly, rather than increasing speed.
