Thermal characterization of laser sintering of nylon-12

To improve the overall product and thermal characteristics of laser sintering of nylon-12, the transient plane source (TPS) method was used to measure the thermal conductivity of nylon-12 powder. The spiral nickel sensor of was sandwiched between the samples of nylon-12 powder packed at 0.547 g/cc, and as the temperature of the sample rose from 40 °C to 170 °C, the thermal conductivity increased linearly. Knowing these trends will help to make ...

Thermal conductivity of polyamide 12 powder for use in laser sintering

In order to better understand how the laser sintering process affects polyamide 12 powder, the authors measured the thermal conductivity of polyamide 12 powder at various densities and conditions. The investigations determined that thermal conductivity of polyamide 12 powder is influenced by temperature and density. The researchers hope to improve the thermal control in laser sintering processes....

Thermal model and measurements of polymer laser sintering

Thermal conductivity measurements were performed on nylon-12 powder over the temperature range from 40-170oC. The thermal conductivity was found to increase linearly over this temperature range. These measurements were performed in order to help better understand how properties of the powder change throughout the process of laser sintering. A one-dimensional model of the thermal energy transport in the powder bed was developed, and it was found to be qualitatively ...

Thermal Conductivity Measurements of Polyamide 12 

The thermal conductivity of polyamide 12 (also known as nylon 12) in loose powder and bulk forms were determined at varying temperatures. The authors stated that there was a lack of information available on the thermal conductivity of this polymer, which is necessary for assessing the material’s performance during laser sintering. It was determined that the thermal conductivity of the powder increased with increasing temperature, while the thermal conductivity of the ...
