Abstract

The invention discloses a three-dimensional printing joint method and structure. The three-dimensional printing joint method comprises the steps that in the step 101, a to-be-jointed position of a component is machined into a groove structure, and the groove structure and a technology cushion plate are machined; in the step 102, the technology cushion plate and the component are fixed, and a specific interval is reserved between the technology cushion plate and the component; in the step 103, the three-dimensional printing technology is adopted for conducting three-dimensional printing at thegroove structure, and accordingly an integral component is subjected to joint connection through the groove connection and / or a cracked component is subjected to joint repairing through the groove structure; and in the step 104, the component obtained after three-dimensional printing in the step 103 is subjected to technology cushion plate removal. The space of 2mm-3mm is reserved on the upper surface of the technology cushion plate and the lower surface of a component additional material connecting area, the enough allowance is reserved for technology cushion plate deformation in the preventing connection and repairing process, the aftertreatment procedures are simplified, and the aftertreatment procedure cost is saved. The invention further relates to the three-dimensional printing jointstructure.

Description

technical field [0001] The invention relates to the field of three-dimensional printing, in particular to a three-dimensional printing joint method, and the invention also relates to a three-dimensional printing joint structure. Background technique [0002] In the past half century, the integration of laser technology, computer technology and new material technology has created a new era of additive manufacturing (3D printing) technology. Different from traditional casting and forging, which require molds to form blanks and then cut and process them, additive manufacturing is a direct net shape technology without molds. Based on computer-aided design, materials are either solidified and deposited layer by layer, or Layer-by-layer stacking and block group welding connection have become an emerging manufacturing technology for the overall structure. [0003] Due to its shape and structure, traditional castings and forgings have uneven thermal stress and are prone to cracks, ...
