Selective laser solidification apparatus and method

摘要

A selective laser solidification apparatus including: a powder bed onto which a powder layer can be deposited, a gas flow unit for passing a flow of gas over the powder bed along a gas flow direction, a laser scanning unit for scanning a laser beam over the powder layer to selectively solidify at least part of the powder layer to form at least one object and a processing unit for selecting a scanning sequence of the laser beam based on the gas flow direction.

1. A selective laser solidification apparatus, comprising:
a build carrier for supporting a powder bed onto which a powder layer can be deposited; a gas flow unit for passing a flow of gas over the powder bed along a gas flow direction; a laser scanner for scanning a laser beam over the powder layer to selectively solidify at least part of the powder layer to form one or more objects; and a processor for selecting a scanning sequence of the laser beam based on the gas flow direction.
