Abstract: A multi-material printer for using multiple materials, e.g., bioinks, to quickly fabricate structures, such as high-throughput screening microfluidic chips. The printer’s light projector for emits light in an exposure sequence to cure material in an additive manufacturing process. The printer further includes a motion stage operable to move a build platform into and out of the reservoir in coordination with the exposure sequence. The printer further includes an indexing stage having a work table for supporting the reservoir. The indexing stage is operable to selectively align the build platform with multiple different materials of the reservoir. The multiple materials may be arranged at distinct angular positions within a single reservoir, and the indexing stage may be operable to rotate the work table to align the build platform with different materials during the exposure sequence for a quick transition among different materials without refilling of materials, exchange of reservoirs, etc.

Abstract: A receptacle for recyclable materials includes an outer housing with a plurality of separate containers removably held therein for receiving different types of recyclable materials, such as glass, metal, plastic and paper refuse normally encountered in a typical household. The outer housing has a removable cover with a plurality of openings therein and a separate pivotable lid closing each opening. Each opening and associated lid is in alignment with a respective container held in the housing, so that material can be placed through the openings in the cover and into the respective containers without the need for removing the cover from the housing. When one or more containers are full, the cover can be removed and the container or containers lifted out by a handle attached to the container. Provision on the housing cover of a lid for each container simplifies emptying of the individual containers when they are removed from the housing.
