Additive Technologies in Prototyping Parts of Binocular

An overview of prototyping methods available for small businesses is provided. Prototyping is carried out using two types of 3D printing: SLA and FDM. Through the above printing methods, operable structural elements of the head of a binocular were obtained. The final prototype was assembled, during which a number of defects in the obtained parts were revealed, such as insufficient product strength and low manufacturing accuracy when using FDM technology. These defect are taken into account in future versions of parts with the refinement and modification of existing CAD models. Also, an analysis of the time and material costs of the production of elements of the prototype. The materials are presented showing the differences between the virtual CAD model and its implementation in the material.
