On applicability of additive technology at agricultural engineering enterprises

INTRODUCTION: This article discusses the experience of using additive technologies at agricultural engineering enterprises for manufacture new types equipment. A comparative analysis strength properties materials used 3D printing is presented. The calculation economic efficiency use technology also given.
 BACKGROUND: Currently, are being actively introduced into production, and in particular parts enterprises. In this regard, current research topic to create parts.
 AIMS: Introduction methods creating their prototypes, with aim import substitution improvement own production enterprises.
 METHODS: course study, an was carried out. At same time, it noted that ABC plastic well machined has highest bending strength. Flex high elastic properties. PLA more tear resistant than plastic, but rigid, which limits its connectors. As a result, chosen further work on technology. manufactured working samples were installed seeder experimental crops out.
 RESULTS: result analysis, positive aspects application noted. characteristics given. An made from can be made. plastics presented characteristic given traditional manufacturing parts. order introduce one Omsk, Details according drawings enterprise: sleeve connecting seed tube coulter seeders. To do this, models created КОМПАС-3D program and, 3d printer, elements sowing machine printed: plug, small-seed large-seed coils. These СС-11 seeder.
 CONCLUSIONS: may due following factors: part unloaded or lightly loaded, there sufficient supply time before product delivered customer, resulting prototype meets all technical requirements, passed tests. experiments, found deviation seeding rate coil original does not exceed allowable 5% amounted 10-20 gr. conducted experiments justification show
