Additive Manufacturing

More powerful, more competitive

Prosilas has 15 years of experience, a machine park with more than 10 industrial machines for 3D printing, more than 20 operators and over 500 customers.

With the third P770 we have an increasingly productive machine park. In this evolved scenario we can define ourselves as a digital factory.

Entreprise 4.0

Prosilas incorporates in his model all the characteristics of a digital native company:

Smart production

New production technologies that create collaboration between operator, machineries and instruments.

Smart service

Technical and “IT infrastructures” that allow to integrate the systems in a collaborative manner and to integrate the companies (supplier – customer) one another

Additive manufacturing

The Observatory Industry 4.0 of the Polytechnic of Milan recognizes Additive Manufacturing among the innovative “intelligent operational technologies”.


Selective Laser Sintering

Selective Laser Sintering

The Selective Laser Sintering is a technique of laser prototyping that employs thermoplastic powders of materials sintered by using a laser beam. Thanks to the rollers, the powders are spread and compacted, the laser scan will then heat them up to a temperature slightly lower than the melting one, just covering up the area identified by the slicing, without any interest for the rest of the powder, and thus creating all the parts of the item, based on the forms prepared through the 3D software. At the end of the production, the extra powder that is not sintered is removed. Then the item can be refined through shaving removal procedures, colouring or metal plating.

This technology enables to accelerate significantly the prototyping processes, to handle quickly possible changes and to realise complex shapes, even with internal holes and cavities, hardly feasible using traditional technologies. Thanks to SLS, indeed, it is possible to obtain high-performance prototypes, with functional characteristics similar to the final material for assembly checking, for size amd shape tests. This is making possible to study a project and its development prior to the production, in order to evaluate the functionality or the design of a product in a very flexible way.

According to the selected material, it is possible to obtain items that can offer mechanical performances or items that are simple models. Moreover, this technology is also really popular among companies that does not require a large-scale production, and sometimes the rapid prototyping is used for “micro-productions”, aimed at creating a set of items (even non-identical items), without the need for moulds and other machinery.

Rapid prototyping differs from traditional mechanical manufacturing processes that work by substraction of material. In substractive manufacturing, the desired shape is obtained by removing pieces from a block of raw material; whereas in additive manufacturing, such as Rapid Prototyping techniques, the items are created by adding material layer by layer.


Automotive parts 1:1 printing

We mould polymer parts of any size, assembled or monolithic parts, minimizing costs thanks to our P770, which ensure a very high production capacity even for large parts.
Our assembly does not require further reinforcements, we deliver the already usable and mountable prototype, resistant to mechanical stress.



The SLA printing is a technology based on the photopolymerization of a resin placed in a vat, on which a laser emits a UV radiation to which the resin is sensitive, and traces high precision shapes layer by layer.

It is used for all these projects that need high precision. Thanks to the stereolithography, it is possible to produce complex models in a high level of transparency. These characteristics make it suitable for the production of parts for the automotive, medical and consumer electronic sectors: particularly for lenses and car lighting, packaging, silicon mold models, wind tunnel tests and quickcast patterns. The parts made with resin through stereolithography have an optimal dimensional stability in the long term and functional properties that makes it one of the most requested prototyping processes.

The parts made thanks to stereolithography lend themselves really well to superficial finishes such as sanding and painting and they are suitable supports for the application of metal inserts and screw threading.


Reverse engineering

Through Reverse engineering it is possible to:

  • reconstruct a mathematics of the object being scanned, ensuring a very high level of detail;
  • Make a comparison between the fabricated object and that initially conceived by the designer, highlighting any discrepancies with the CAD file;
  • Accurate dimensional control on products based on the mathematics sent by customers and certified reports;
  • Control service to company that manufactured the parts with other technologies and check of any changes between part wanted by the customer and part actually realised;
  • Reconstruct CAD mathematics on objects that have gone out of production or that have lost their equipment.
