INFLUENCE OF PRINTHEAD NOZZLE DIAMETER ON MECHANICAL PROPERTIES OF FDM PRINTED PLA MATERIAL AND PRINTING TIME

Abstract

There are various 3D printing parameters that affect the mechanical properties of FDM printed materials as well as the final price of the finished product. One of the influential factors on printing time is certainly the diameter of the print head nozzle. In this paper influence of print head nozzle diameter on the mechanical properties of FDM printed PLA material was analysed. Tensile and flexural mechanical properties were examined, and tensile strength, elastic modulus, flexural strength, flexural modulus, and strain are presented in results. Also, the influence of the nozzle diameter on the total printing time was analysed because the printing time directly affects the final price of the product.
