The two previous posts by SLS users did a good job of answering this question
from a customers prospective. Thank you.

The CO2 lasers that are uses in the Sinterstation 2500plus are rated for 25,000
hours life.

Subject: Question laser-liftime SLS

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,
