APPLICATION OF ADDITIVE TECHNOLOGIES IN THE TECHNICAL SERVICE OF GARDEN EQUIPMENT

Abstract

The paper considers the analysis of the market for garden equipment. The authors consider some information on garden equipment failures, using an example of Husqvarna trimmers. They also assess a possibility of using additive technologies to manufacture sliding bearings for mechanical drives of garden equipment. For testing the physical and mechanical properties, a batch of samples was prepared by means of 3D printing using FDM (FFF) technology. According to the ASTM D638-14 standard, samples were prepared on a PICASO 3D Desingner X Pro 3D printer. Samples were made of ABS-plastic and PA12 with diff erent degrees of fi lling: 20, 50 and 100%. It is noted that the destruction pattern of samples made of diff erent materials is signifi cantly diff erent. Samples made from ABS plastics are more fragile than samples made from PA12. According to the test results, PA12 with 100% fi lling have shown the best results, which makes them suitable for use in the manufacture of slide bearings by means of 3D printing.
