Abstract

The paper discusses methods of welding or joining of two separate filaments for FFF/FDM Technology of 3D printing. Article also concerns advantages and disadvantages of mentioned methods. Various materials used in this printing technology are described, their welding capability and physical properties such as working temperatures and their suitability. The article describes various devices and prototypes used in solving the above mentioned problems. The aim of the article is to point out the efficiency and ecological recycling of filament shavings for non-degradable materials used in 3D printing, such as Acrylonitrile butadiene styrene (ABS).
