Abstract

The invention discloses a dynamic cylinder powder laying type 3D printer, and belongs to the field of material increase manufacturing. According to the dynamic cylinder powder laying type 3D printer, a powder box is fixed, and a powder laying scraping cutter is arranged on the lower portion of the powder box, so that a powder supply device and a powder laying device form an integrated structure. When a forming cylinder retreats and a forming cavity of the forming cylinder is located below an opening of the powder box A, as a piston moves downwards, the forming cylinder has a gap, powder to be used flows into the forming cylinder from a cavity of the powder box A, and powder supply is achieved. When the forming cylinder moves forwards, the forming cylinder takes away the to-be-used powder on the upper surface of the forming cylinder, as the scraping cutter is arranged on the lower portion of the powder box A, the scraping cutter moves relative to the forming cylinder, the to-be-used powder on the upper surface of the forming cylinder is flattened in a scraping mode, and powder laying is achieved. After powder laying is finished, a sintering (or curing) device starts to work, and the to-be-used powder is sintered (or cured) in the area needing sintering (or curing). After sintering (or curing) is finished, namely one time of circulation of the printer is finished, the forming cylinder retreats again, circulation begins again and is repeated, and that is the printing process of the 3D printer. The dynamic cylinder powder laying type 3D printer is simple in structure and high in efficiency.
