Abstract
A machine for machining workpieces and/or for producing molded bodies by location-selective solidification of material powder to form connected regions by means of a focused laser beam, including: a process chamber which can be closed by a process chamber door and which encloses a process space, a material powder container cabinet, which can be closed by a door, for storing material powder, and a suction system. The suction system has a fan for generating an air flow, a first suction apparatus fluidically connected to the fan by a first waste air duct to suction particles out of the process space, and a second suction apparatus fluidically connected to the fan by a second waste air duct to suction particles out of the material powder container cabinet. The first suction apparatus has means for controlling its suction power and/or the second suction apparatus has means for controlling its suction power.
