  SLM Solutions Industrializing Metal Additive Manufacturing
ADVERTORIAL
 The tallest powder bed
fusion chamber on the
market, the SLM®800 effi-
ciently builds large compo-
nents and opens new
production possibilities.
Using SLM Solutions’
proven quad-laser technol-
ogy, the SLM®800 also uti-
lizes a patented sintered
wall gas flow that prevents
disruption of the laser for
consistent quality and the
durable metal recoating
brush ensures stable pow-
der recoating while en-
abling error correction
during the build. Vertically
extending the build enve-
lope reduces exposure per
layer and internal stresses
with a higher surface quality for long com- ponents. Decreased supports through ver- tical orientation also reduces material usage and post-processing.
The SLM®800 is equipped with a per- manent filter module that traps process soot in a sintered plate filter and purges with gas. The waste material is coated with an inhibitor and stored in a bin for dry disposal, while clean gas returns to the process chamber, stabilizing gas flow to ensure part quality throughout long builds without interruption. The elimination of consumable filter cartridges increases safety while improving machine uptime and reducing costs. Operators no longer need to flood filters, and waste manage- ment is simplified as controlled diffusion renders a standard dry material for dis- posal.
Each SLM®800 features an integrated powder tank to supply the machine with a direct source of material. The additional central powder supply unit (CPS) features two 220-liter tanks, one fixed for delivery to the machine and one portable for pow-
der refill. Sieves are located both in be- tween the two CPS tanks and on the ma- chine directly before use to ensure powder quality throughout the process.
The SLM®HUB utilizes a linear axis to drive build cylinders between three inte- grated stations and directly into or out of the SLM®800 machine. Setup of new sub- strate plates and removal of finished parts takes place in the handling position while dedicated locations in the parking cham- ber allow for pre-heating of cylinders be- fore or controlled cooling after a build. The integrated powder removal chamber sep- arates the build cylinder from the sub- strate plate and rotates the build with vibration motions. A specially designed gas flow ensures safe depowdering within an inert atmosphere. All powder can be recovered and returned to the centralized powder supply. As many as five SLM®800 machines can link to one SLM®HUB to optimize utilization with full automation to minimize costs.
