Design of dual-head 3D printer

Abstract

Fused Filament Fabrication (FFF) printers are usually designed to create a product with one single material. Some of them allow fabricating items in multiple colours but creating a single product consisting of two different materials remains an advantage of industrial 3D printers only. The aim of this research was to develop a design of a device with two printheads which enables to print products with two different materials, compatible with a cheap and commonly available FFF device Prusa i3MK2S, and the subsequent production of a prototype. A key aspect of the design was the hardware compatibility of the device with the given printer while maintaining the maximum possible printing area.
