Abstract

The dissertation thesis research 3D printing using the FDM method in order to achieve faster printing, reduce the cost of 3D printing and improve the mechanical and physical properties of 3D printed parts. The principle of 3D printing and reasons why it is good to reduce cost of 3D prints and speed up printing are described. The thesis presents a method called filled 3D printing, which should significantly reduce printing time, reduce cost of 3D prints and improve mechanical and physical properties of 3D printed parts. This method consists from 3D printed hollow part, which is then filled with a hardenable liquid material. Some filling materials were tested and described, including epoxy resins, polyurethanes and concrete. The principle of filled 3D printing method was tested on several parts - rods for bending test, plate for vibro-acoustic test and loudspeaker cabinet for acoustic test. These tests examined the mechanical and physical properties of filled 3D printing and were compared with traditional 3D printing and other materials (metals, MDF, wood).
