Original Abstract

Currently, 3D printing is used in various industries from the production of prototypes to final products. From the point of view of sustainable development, materials based on polylactic acid (PLA) are suitable, for which it is possible to ensure controlled degradation. In terms of aesthetics, but also applicability, it is important to know the thermal properties of filaments, but also the final products with different types of additives. In the present paper, PLA samples with various pigments and conductive materials are studied. The transient step wise method was used to study the thermal properties. This method allows determining all three basic thermal parameters (thermal conductivity λ, specific heat capacity cp, and thermal diffusivity a). It was found that for samples with pigments, these parameters were in the range of values λ=(0.15 - 0.25) W/m/K, cp=(900 - 1100) J/kg/K, and a ≈ 0.15 mm2/s. For samples with electrically conductive admixtures, are the equivalent parameter in range λ=(0.22 - 0.30) W/m/K, cp=(400 - 600) J/(kg.K), a ≈ 0.17 mm2/s. It turned out that electrically conductive materials (PLA with metal admixtures) show a very good coefficient of thermal conductivity and lower specific heat capacity, while materials with admixtures of pigments show a lower thermal conductivity and higher specific heat capacity. These materials we use, in present time, for construction of boxes for measuring thermal properties of low temperature PCM materials (up to 50 °C) and an electrode system for measuring the electrical properties of thin film semiconductors and crystals.
