The opportunities offered by 3D printing are now multiple and the continuous developments of technology allow us to respond promptly even to the needs of sectors that were considered too specific such as hydraulics and hydrothermohydraulics.

An innovative solution

In particular, the innovative combination of industrial 3D scanning and 3D printing with SLS tencology offers a wide range of opportunities. In particular, in the hydro-hydraulic sector, the production of implementation and replacement parts on furniture, taps, sanitary ware, air conditioning and convector systems represent one of the greatest challenges and needs.

It is precisely here that additive manufacturing represents an excellent alternative, with numerous advantages over more traditional technologies, both from the point of view of the aesthetic and mechanical performance guaranteed on the parts produced, both for its ability to reproduce obsolete or discontinued components, intervening if necessary on the optimization of geometries quickly and functionally .

Rebuilding spare parts that are now out of production or whose mold has been lost has never been so simple and fast!

A process that we at Prosilas know well and that through the use of our 3D scanners and the application of reverse engineering has allowed us to produce a particular model of hydraulic tap breaker and a shower customized to the specific request customer’s.

With the 3D file  from the scanning of the part out of production, the SLS technology used in our laboratories Prosilas allows  to 3D print functional elements, also offering the possibility to work on large results or series (working chamber 680x380x540 mm), being able to choose from a wide range of materials: PA12, PA12+Glass spheres, PA12 + Carbon fiber, PP (Polypropylene). 

An opportunity, that of putting back on the market spare parts out of production getting the reconstruction through additive technology, that not only allows to answer to a specific need without looking for solutions of fortune or sketched, but which makes the production itself much more sustainable and performing. 

On-demand warehouse


The case of the 3D reconstruction and printing of the tap and a custom shower model shows how on the one hand 3D printing allows to have a production according to the needs, thanks to a virtual warehouse on demand without the need to manage a physical storage and from the other offers the opportunity to rethink the component in additive, in order to obtain an improvement of the mechanical performances. 

Innovative and customized additive solutions that we propose, supporting companies in all sectors, even those universally recognized as the most demanding just like the world of hydrothermohydraulics.

Prosilas for Philipp Plein, the shoe revolution starts from a 3D sole

Philipp Plein Case History

Prosilas: AM Service & Consulting 

Since the beginning of our entrepreneurial adventure, in 2003, we have chosen not to specialize in a particular production sector, preferring to offer as a service to customers in different sectors. Thus, we have maintained a flexibility that has proved particularly successful when, in our transition from prototyping service to manufacturing ally, we were commissioned the sole of a shoe for one of the brands symbol of fashion luxury: Philipp Plein.


R&D on Tpu 

In 2020 we enabled the use of TPU, a rubber material widely used in the moulding of soles, on our SLS production systems.  This gave us the opportunity to start the collaboration with Philipp Plein, with the aim of creating a capsule collection of footwear in which to combine innovation and luxury, dedicated to a specific niche of the brand’s customers.   At the heart of the work, for us, was the creation of an attractive model in line with the taste of the brand and the development of a product that exceeded a series of requirements of strength and durability.

 3D Sole

In fact, the sole is one of the crucial elements of a shoe and one of the most stressed by the use. We then conducted a detailed study and a deep work on design and process to ensure replicability. For this reason we also supported the company that would then assemble the final shoe, facing and solving together specific processing problems that usually do not concern those who make prototypes.

The result ?

First, we got a sole completely out of the standard of a traditional ones, with a latticed structure; then, the opportunity to innovate the style thanks to the possibilities offered by 3D printing; finally, we opened doors to unique pieces, unthinkable (or infinitely more expensive) when all the process of creation must use injection moulding. 

Thank to a work like this, a progressive set of know-how is created that is completely new but can be used in all subsequent experiments. So, for example, for Philipp Plein shoes, we conducted several tests on the tightness of the colors of the soles, especially white – which should not turn yellow or turn on other shades – and black – which should not shin, so it can not be painted.

How was that possible?

The problem-solving business approach was essential

“There are no closed doors,” explains our CEO Vanna Menco, “We always accept challenges, we like to evolve and find solutions”. In this the imprinting of my father was fundamental, because – she continues – he “loves to crack his head on problems” and not by chance he still leads the Research and Development department.

Our transition from suppliers to consulting service  has been made possible by a know-how developed to support the customer at all stages of production, making available our deep expertise in 3D printing. So, we went from consulting at the prototype stage to consulting for all product development, also providing knowledge on specific steps, such as the blend of the material to be used to achieve a certain result.

Our constant commitment to be the best possible consulting service for AM world.

Biocompatible material for 3D printing: Polycaprolactone

Biocompatible material for 3D printing: Polycaprolactone

Case History – Medical

Application in the Medical sector realized through the use of biocompatible and absorbable materials – Polycaprolactone – processed with 3D printing technologies and additive manufacturing SLS – Selective Laser Sintering.


Polycaprolactone – PCL: biocompatible material for 3D printing

Our team of experts has perfected a particular formulation of material capable of producing functional parts implantable in the human body.

In this specific case we produced a biocompatible and absorbable material composed of Polycaprolactone and Hydroxyapatite. The chemical composition of the material made possible the realization of a special stent that was implanted in a 5 year old child suffering from bronchcomalacia at the Bambino Gesù Hospital in Rome.

Bronchial stent in 3D printing:  design and implementation

The process of producing the stent was the result of 3 years of research and development that Prosilas has faced pro-bono in order to realize the part in question. The realization was possible through a design phase and a production phase.

The design phase of the geometries was performed on the basis of a computed axial tomography (CT) showing the area to be reproduced. The acquired images were useful to create a new geometry completely customized on the patient.

The case study is the first and only in Europe.

Once the geometry was validated, hundreds of tests on 3D printing (SLS) technologies and materials were performed. The right balance between process parameters and chemical composition of the material led to the creation of the stent.
