Abstract
In recent years, additive manufacturing technologies have been increasingly used in both unique and small series production. In such cases, the component must remain functional under real-life conditions and be able to bear the load. In many cases, the materials are already suitable from a strength point of view, but sometimes (machine parts, outdoor use) the models must also operate reliably at higher temperatures. This is enabled by a new heat-tolerant material, HT PLA, in the case of the most common additive manufacturing technology (FDM). In some cases, cooling is required during production, especially for parts with large overhangs, where it is necessary to solidify the material as quickly as possible to achieve the required surface quality. In this paper, we investigated the effect of cooling on mechanical strength during the manufacturing process.
