摘要：
Disclosed herein is a process and a device to colour a part manufactured by using a 3D printing process of the "Fused Filament Fabrication" (FFF) or "Fused Deposition Modelling" (FDM) type, using UV ink dispensed by inkjet printing processes. Specifically, it consists on an upgrade for common 3D FFF printing machines that allows them to print coloured parts.
技术问题语段：
The technical problem addressed in this patent is the difficulty of effectively coloring parts manufactured by FFF 3D printing. Previous methods have led to poor quality, difficulty in controlling color, and problematic adhesion of coloring materials. The patent seeks to provide a new method for achieving high-quality coloration in FFF 3D printed parts.
技术功效语段：
The invention is about a process and equipment upgrade for 3D printing using FFF technology to allow for the coloration of parts as they are manufactured. Previous methods have not been effective in achieving true freedom in color choice, and existing systems have limitations in terms of pigment adhesion and the size of color spaces. The invention uses UV radiation curable ink that can be applied using an inkjet system, and a radiation emission apparatus with the required wavelength. The technical effect is the improvement of coloration in FFF 3D printing, allowing for the freedom to choose pigments and the ability to control color change in each layer.
权利要求：
1. Apparatus for colouring 3D prints fabricated with an extruding head characterized by being formed by an inkjet head and an UV curing implement.
2. Apparatus for colouring 3D prints fabricated with an extruding head according to claim 1, characterized by the inkjet head being mounted in such a way as to point to and permit the painting of the outside perimeter of the part.
3. Apparatus for colouring 3D prints fabricated with an extruding head according to claim 2, characterized by the inkjet head being mounted on a rotating fashion.
4. Apparatus for colouring 3D prints fabricated with an extruding head according to claim 3, characterized by the inkjet head working with a CMYK colour scheme.
5. Apparatus for colouring 3D prints fabricated with an extruding head according to claim 3, characterized by the inkjet head working with a single colour.
6. Apparatus for colouring 3D prints fabricated with an extruding head according to claim 3, characterized by the inkjet head working with a more than one colour, at will.
7. Apparatus for colouring 3D prints fabricated with an extruding head according to claim 3, characterized by the inkjet head working with a specific colour, besides others, used specifically as a primary layer.
8. Apparatus for colouring 3D prints fabricated with an extruding head according to claim 1, characterized by the UV curing implement being mounted in such a way as to point to and permit the curing of the outside perimeter of the part.
9. Apparatus for colouring 3D prints fabricated with an extruding head according to claim 8, characterized by the UV curing implement being mounted on a rotating fashion.
