Discover the process

The design process followed naturally and continuously, which enabled the complete success of the process and the product.

2D Design

As a first step and after many hand sketches, various 2D design proposls were created, from which one was chosen as the final one and the starting point reference for 3D modeling.

3D Model

2D design was followed by 3D modeling. 3D modeling took over a key development phase with the goal of respecting technological limitations, design guidelines and overall approach as it is a family of products.


The next step after 3D modeling was the creation of 3D printed prototypes, followed by the technological development of molds and the start of production.


Global competitive product

The main imperative was to create a competitive global product based on superior innovations in design, use and features, taking into account the specifics of the product and the global use.
