Abstract: The present invention provides a residue removing device for removing residues in a partition plate, and a related 3D printer for use on a working platform. The partition plate e.g. of a 3D printer has a plurality of openings arranged in an array, and residues may be filled in the openings. The residue removing device includes a base plate and a plurality of jutting pins disposed on an upper side of the base plate. The jutting pins are arranged in an array corresponding to the openings array such that the jutting pins are capable of being inserted into the openings, in order to easily remove the residues in the openings of the partition plate.

Abstract: The present invention is to provide a resilient switch mounted in a housing and comprising a flexible arm including a first seat formed on one end of the flexible arm and a second seat formed on the other end of the flexible arm. After fastening the second seat on a first inner surface of the housing, the pressing member projects out of the housing through an opening on the first inner surface of the housing. A first projection is formed on a second surface of the flexible arm opposite the pressing member and is disposed proximate the second seat. A portion of the first projection opposite the flexible arm is extended to be proximate a second inner surface of the housing opposite the first inner surface of the housing. By utilizing this resilient switch, the first seat moves toward the second inner surface of the housing when a pressing force is exerted upon the pressing member.
