Abstract. The traditional method of replicating shoe accessories using a silicone mask is characterized by a discrete process, a significant proportion of manual labor and low productivity (the full cycle from a wooden standard to a finished aluminum mold takes from two to four weeks).

The advent of industrial selective laser melting (SLM) installations has opened up the possibility of a partial modernization of the chain — replacing a wooden billet with a polymer 3D model. Despite the increased accuracy of prototyping, this approach does not eliminate the main barrier to mass production: the need for subsequent milling or die casting, the accumulation of errors during reshooting and high consumption. The article provides a justification for the effectiveness of additive technologies to eliminate intermediates, which boils down to the development of an optimized technological process for creating functional molds for the production of shoe soles by directly switching from a digital 3D model to metal or polymer tooling using SLM/DMLS and SLA methods, bypassing the stages of physical prototyping and injection molding. To do this, we conducted a content analysis of the main categories of technology for subtractive and additive manufacturing of a master sole model, developed an optimized technological process for creating functional molds for the production of shoe soles through a direct transition from a digital 3D model to metal or polymer tooling, compared and evaluated materials for the manufacture of sole molds (temperature conditions, speed and a resource). This research was conducted as part of the dissertation of L.A. Kireeva «Research and development of constructive and technological solutions for the bottom of shoes using digital technologies».
