Abstract

The invention relates to a 3D printing forming method, and relates to the technical field of 3D printing. The 3D printing forming method comprises the following steps that a printing model is established, at least two kinds of supporting holes are reserved in the printing model, and the at least two kinds of supporting holes are arranged in a staggered mode; and printing is started according to the printing model, the supporting holes are filled, and a plurality of supporting columns are formed in the product formed through printing. When the 3D printing forming method is used for printing, original printer equipment does not need to be changed, only the printing model needs to be subjected to adaptive planning, and an arrangement space for forming the supporting holes of the supporting columns is reserved; and original printing materials do not need to be changed, only the reserved supporting holes need to be filled while normal printing is completed so that the supporting columns can be formed, the interior of the product can be connected through the supporting columns, so that the internal printing layers of the printed and formed product are reinforced, and the layering or fracture problem is solved.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a 3D printing forming method. Background technique [0002] 3D printing technology is based on digital simulation files and prints models layer by layer. Its application fields are becoming wider and wider, especially in FDM (Fused Deposition Modelin, hot melt deposition solidification molding method) hot melt technology, which has low cost. , high strength, non-toxic, non-chemical pollution, so it is widely used and liked by more and more users. However, the workpiece printed by FDM is often affected by layer-by-layer accumulation, and the bonding strength between layers is low, resulting in the manufactured model being prone to delamination and fracture, which will greatly affect the quality of the printed product. Contents of the invention [0003] Based on this, it is necessary to provide a 3D printing molding method for the technical problem that the 3D printing model...
