Modifications techniques for wood/thermoplastic filaments used in 3D printers
A 3D prototype manufacturing has become quite widespread nowadays. Particularly, there is increasing interest to desktop 3D printers because they allow the user to easily produce objects directly as 3-Dimensional CAD (Computer Aided Design) images. The main reasons in the increase of 3D printers are unlimited product customization, less waste than traditional subtractive methods, and easy to use. As a function of increasing 3D printer, the demand for the filaments have also increased in last decade. The filament used in the 3D printers can be produced different materials. Although the neat fossil-based thermoplastics was still the most used filaments, environmentally friendly filaments are preferred by the user because of harmful effects of fossil-based thermoplastics to the environment. The filament producers have focused on the production of natural fiber/thermoplastic filaments as an alternative to petroleum based thermoplastic filaments. The major drawback of natural fibers is incompatibility with biodegradable or non-biodegradable polymers, which negatively affect the physical and mechanical properties of filaments, as well as printed objects. This study gives the modification techniques for wood/PLA filaments used 3D printers.
