Spart Geld und behebt zugleich das Problem, dass die Composite Platten mit der Zeit schwächeln

Wie verhält es sich kostenmäßig, wenn wir überall Alu anstelle von Alu-Kunststoff-Verbundplatten nehmen? Die Aussage:
…because the plastic core tends to weaken after prolonged laser radiation. This would cause the panel to start sagging after a while, hence the aluminum-only panels for the bottom. gibt zu Denken!
Weiteres Zitat:
Under normal conditions the laser beam goes through the lens which means it has the highest energy density after about 76mm and then looses its energy density quite rapidly.
For example, after 0.2m the beam has a diameter of ~20mm and an energy density of 1/400. In the failure mode where the beam stays unfocused and hits the bottom panel as a ~8mm beam
