Title:
ROUNDED-PARTICLE PLASTIC POWDER IN PARTICULAR FOR APPLICATION IN LASER SINTERING, METHOD FOR PRODUCTION OF SUCH A POWDER AND LASER SINTERING PROCESS USING SUCH A POWDER
Document Type and Number:
WIPO Patent Application WO2004050746
Kind Code:
A8
Abstract:
The invention relates to a laser sintering method for production of a three-dimensional object in which sequential layers of the object to be formed, made from setting powder material are set in positions corresponding to the object, whereby the material of construction used is a powder in which the grain size upper limit for the powder particles is less than 100ñm, the D0.5 value is less than 55ñm, the BET surface area is smaller than 5 m<2>/g and the powder grains have an essentially spherical form.
