Constructive Solution for Multi-filament 3D Printing

The article presents a new 3D printer constructive model using an extruder that can work with three types of thermoplastic filaments as raw material. The designed and realized 3D printer has the ability to produce multilayer multi-colour parts of materials with different properties and characteristics due to the extrusion head with a special construction - diamond type, which allows the control and combination of the three types of filaments.
