Dual Paste Extruder

The project consists of the design, execution and start-up of a numerical control system capable of extruding two types of pasty materials, without these having to come in wire format as usual. In this way, 3D printing of chocolates and sugar pastes is made possible with remarkable results, in addition to other inedible pastes such as ceramics as well as the combination of two of these. Its operation consists of a rack and pinion system that, activated by the stepper, directly pushes the plunger of a syringe.

With this system, the range of materials for our printed parts is expanded, admitting a great variety of viscosities in adapting tips of different diameters in the syringe, and also the possibilities of this technology in different market sectors such as culinary or construction.
