Laser-sintering (LS) is an additive layer manufacturing process that creates three dimensional solid objects directly from CAD data by using one or more CO2 lasers to selectively sinter powdered materials in a controlled chamber and part bed. The chamber is maintained at a temperature just below the melting point of the powder so the laser energy raises the temperature by only a few additional degrees.  

After a layer (typically .075mm to .125mm) is sintered, the part bed lowers and a subsequent layer of material is then deposited over the previous layer and sintered. The process is repeated until all of the object’s layers have been sintered together. As the part is continually lowered in the part bed during the build process, it ultimately rests in a bed of loose power and does not require additional support structures. After the part is removed from the powder bed, the excess powder is simply brushed away and then part is ready to use. 

The EOSINT P 800 offers companies the ability to use high performance polymers such as PEEK and PEKK for prototype development and low-run manufacturing of complex geometries that has not previously been possible in any other rapid manufacturing process.

Royal is currently working with the US Navy, the US Air Force and OEM’s in the aerospace, medical and energy industries to develop and optimize laser-sintered high temperature materials for end-use applications.
