Additive technologies for prototyping. Control of geometrical characteristics of abs plastic details for determining the original print sizes

Abstract

Plastics of various types, such as ABS, PLA, etc. are used to create prototypes of parts by the method of layer-by-layer deposition (FDM). The low cost of these plastics determines the relevance of using this type of prototyping when developing models. One of the main problems with the use of 3D printing is plastic shrinkage when using heating platforms. The article presents the results of the study of the “Cube” detail after different printing modes to determine the most preferable mode when using universal ABS plastic. For the production of products with high requirements to the geometric characteristics, recommendations on making changes in dimensions at the stage of modeling parts are proposed, which allows us to eliminate the problem of material shrinkage.
