Problems solved by technology

However, this technology still has the following technical problems: (1) the glass-forming ability of amorphous alloys is extremely high; (2) in an open environment, the heat loss of supercooled liquid amorphous alloys is very fast, which seriously affects the performance of amorphous alloys. viscosity
High viscosity will inevitably affect the diffusion connection, resulting in weak welding between layers, or even detachment, seriously affecting the mechanical properties and reliability of formed parts

Abstract

The invention discloses a 3D printing system suitable for a micro-gravity space environment. The 3D printing system comprises a housing (1) and a control unit (2) as well as a workbench (12) arrangedinside the housing (1), a base plate (11) arranged on the workbench (12), a feeding unit, and a processing head part, wherein the feeding unit comprises a storage device (4), a feeding mechanism (6) arranged at one end of the storage device (4) and an ejecting-out mechanism (3) arranged at the other end of the storage device (4); and the processing head part comprises a small laser unit (7). The invention further discloses a 3D printing method suitable for the micro-gravity space environment. The system avoids the crystallization risk that an amorphous alloy is connected and formed in a thermoplastic mode under a long-time high-temperature condition, can achieve coaxial feeding, is high in forming efficiency, guarantees uniform and continuous discharge, can form a part of any shape, can obtain a large-dimension amorphous alloy part with high forming quality, can keep good equipment work stability, and is especially suitable for on-track manufacturing in the space environment.

Description

technical field [0001] The invention belongs to the technical field of metal 3D printer manufacturing, and more specifically relates to a 3D printing system and method suitable for a microgravity space environment. Background technique [0002] With the rapid development of aerospace technology, research projects such as exploring deep space, building alien bases, and alien immigration will gradually be put on the agenda. However, to achieve long-term on-orbit material and life support, the construction of space application facilities, and the construction and operation of alien bases, it largely depends on how to achieve efficient, reliable, and low-cost "space manufacturing", so as to overcome the existing rocket launch. The method restricts space exploration activities in terms of load, volume, and cost. Space manufacturing can directly use space resources such as solar energy and raw materials to achieve self-sustainment. It is worth noting that the microgravity enviro...
