Abstract


The research object is the cooling of polymeric materials in additive technologies.

The purpose of the work is the study of the cooling of polymeric materials while blowing a solidification zone in 3d-printer with air flow through a cooling nozzle.

As a result of the calculations performed according to the proposed methodology, it was demonstrated that blowing the zone of solidification of polymeric materials by air flow through the cooling nozzle allows for a flow rate of w = 8.5 m/s to reduce the cooling time of the material by almost 2 times, which, in turn, enables to increase printing performance. In addition, cooling with a strictly directed air flow through the nozzle eliminates the need for thermal protection of the print head of a 3d-printer that occurs when blowing fans are used.
