Abstract: A selective laser melting technology-based apparatus for preparing a gradient material, comprising a laser scanning array lens, and a powder storer, a powder mixer, a powder scraping plate, and a working platform that are provided in sequence from top to bottom; the powder storer is provided with two or more partitions; a bottom portion of the powder storer is provided with an outlet; the powder mixer is provided under the powder storer and is a horizontally provided rotational mixer; the powder scraping plate is disposed under the powder mixer; the working platform is provided under the powder scraping plate; the laser scanning array lens is provided on the working platform. The present invention further relates to a method for preparing a gradient material, comprising powder storing, powder scraping, powder mixing, powder laying, and printing. The method can guarantee the two-phase powder ratio in each layer of powder not change.

Abstract: A method of operating a laboratory sample distribution system is presented. The laboratory sample distribution system comprises a number of sample container carriers. The sample container carriers are adapted to carry one or more sample containers. The sample containers comprise samples to be analyzed by a number of laboratory stations. The laboratory sample distribution system also comprises a transport plane. The transport plane is adapted to support the sample container carriers. The method comprises allocating an area of the transport plane as a buffer area. The buffer area is adapted to store a variable number of sample container carriers. The method also comprises controlling the buffer area using a puzzle-based control scheme or using an aisle-based control scheme as a function of a storage density of the buffer area.

Abstract: A method of operating a laboratory sample distribution system is presented. The system comprises sample container carriers comprising a magnetically active device and configured to carry a sample container, interconnected transport plane modules configured to support carriers, and electro-magnetic actuators arranged in rows and columns below each transport plane module and configured to move a carrier on top of the transport plane modules by applying a magnetic force to the carrier. The method comprises assigning transport plane modules to a route category. At least two traffic lanes are formed on the route categorized transport plane module. The carriers are moved within each traffic lane in a transport direction. The transport directions are opposite to each other. The method also comprises assigning another transport plane module to a waypoint category. A change from one transport direction to the opposite transport direction is possible on the waypoint categorized transport plane module.
