I regulary read messages about laser-change or power-loss on lasers wich are used for stereolithography. Are lasers wich are used for SLS also subject to change after functioning for a certain period? If so, what is the lifecycle of an 'SLS-laser'; If not, why not?
Does DTM apply another kind of laser system than EOS (?); DTM claims to handle many materials (polymers and metals) on one machine where as EOS has different machines for each type of use/material (P & M series machines)
Thak you in advance for your reply, with kind regards,
