摘要
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 100µm, the D0.5 value is less than 55µm, the BET surface area is smaller than 5 m2/g and the powder grains have an essentially spherical form.
