Title:
DISK-TYPE MULTI-MATERIAL SELECTIVE LASER MELTING-BASED PROTOTYPING APPARATUS AND METHOD
Document Type and Number:
WIPO Patent Application WO/2018/133599
Kind Code:
A1
Abstract:
A disk-type multi-material selective laser melting-based prototyping apparatus, comprising a prototyping chamber (16) and powder supply means. The powder supply means is a rotatable disk-type powder cylinder; the disk-type powder cylinder is of a cylindrical structure; the interior of the disk-type powder cylinder is divided into four equivalent powder cylinders (11, 5, 7, 9) by means of partitions (8); the four powder cylinders are used for holding powders of different materials; when a rotating shaft (6) of the disk-type powder cylinder rotates, the four powder cylinders are driven to respectively and alternately align with a powder spreading position (13) of the prototyping chamber (16), so that the powders in the powder cylinders are spread onto a prototyping cylinder (12) by means of a powder spreading mechanism. The present invention also relates to an operating method for the apparatus. The apparatus features high flexibility, a simple structure, small space occupation, and low costs, satisfies the prototyping requirement of machining one part using a plurality of powders, greatly improves the efficiency and quality of prototyping, and greatly improves the favorable metallurgical bonding performance of different materials of a part due to that a prototyping chamber does not need to be opened for powder changing during a machining process.
