In-space-capsule 3D printing device for microgravity environment

Abstract

An in-space-capsule 3D printing device for a microgravity environment comprises a printer, wherein a function composite closed case is arranged outside the printer, an air outlet of the printer in the function composite closed case is connected with an air inlet of an atmosphere and temperature control device, an air outlet of the atmosphere and temperature control device is connected with an air inlet of the printer in the function composite closed case, the function composite closed case of the printer is connected with a vibration reduction platform, and a printing platform is connected onto the vibration reduction platform; a heat-insulating layer capable of keeping the temperature field in the case stable is contained in the inner surface of the function composite closed case, a noise reduction layer for shielding noises produced during printing is arranged outside the heat-insulting layer, and an electromagnetic shielding layer for preventing mutual electromagnetic interference between the printer and the outside as well as a protection layer for ensuring the printer strength are arranged outside the noise reduction layer. The device is adapted to the space microgravity environment and ensured to be matched with a space navigation platform, and space manufacturing is realized.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a 3D printing device in a space capsule facing a microgravity environment. Background technique [0002] With the development of aerospace technology, the concept and implementation methods of "space manufacturing" are gradually developing and improving. "Space manufacturing" refers to the on-orbit rapid on-demand production of vulnerable and consumable parts, spare parts, special tools, micro-satellites, radars, and solar receiver panels in spacecraft, space stations, and alien bases. manufacture. The biggest influencing factor of "space manufacturing" is the microgravity environment, which refers to the environment in which the apparent weight of the system is much smaller than its actual weight under the effect of weightlessness. In a microgravity environment, the subsidence phenomenon caused by the density difference and the convection caused by gravity will almost disa...
