How it works

Digital prototyping: how to visualize an idea and quickly transform it into a real object!

Working together with customers, we evaluate all elements of the project and we discuss the technical and planning choices in relation to the tools, machines and the flow of production.

Defined all the parameters, we proceed in supplying the finished files to 3Dprinting, to create a resin prototype or a metal prototype, ready for the mouldmaking.

What does the customer furnish us with?

What do we furnish  to the customer?

The handmade or digital drawing
in 2D or 3D.


The technical information about
the raw material to use
(for example: gold type, approximate size of the stones
and the total final weight of the object)




A 3D prototype ready for production:
a file ready to be printed in resin or to be melted in metal, and then to be mouldmade.

The work process explained step
by step, optimized for  the current flow
of production and the customer's equipment.
