THE INFLUENCE OF TECHNICAL LIQUIDS ON THE PROPERTIES OF ELASTOMERS PRINTED USING 3D TECHNOLOGIES

Abstract

One of today's technologies, 3D printing, known as adaptive manufacturing, can often be a successful solution for creating new products, restoring broken parts, re-modelling, refining, redesigning. 3D printing in polymeric materials is currently very popular. However, over time, depending on the operating conditions, polymer products age - change and deteriorate. For this technology to work, you need to know whether the printed parts will be reliable and durable. The manufacturer will usually provide the resistance properties of the raw materials for 3D printing to chemically aggressive environments. The properties of the printed product may be different. This research work presents the results of a study on the absorption of coolant and engine oil by FDM and SLA 3D printed elastomer parts and the effect of these fluids on the product properties. The parts were soaked for 36 days. The study showed that all the tested products absorbed the technical fluids with an increase in their mass. However, the properties of the materials printed with FDM and SLA technologies are different. FDM elastomers absorb coolant a little (0.08 - 0.09 g in 36 days), oil - more 0.14 - 0.21g. SLA-type resin products absorb more coolant (0.1 g per 36 days) and used oil (0.03 g to 0.22 g). Coolant and oil act as softeners for SLA printed elastomers.
