Prosilas: Technologies for Additive Manufacturing

Production and prototyping systems

3D printing technologies and additive manufacturing

“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 fleet. In this advanced scenario we can define ourselves as a
digital factory.

Technologies 4.0

Prosilas has all the features of a digital native company:
– Smart production
– New productive technologies able to create a collaboration between operator, machines
and tools
– Smart service
– “Informatics infrastructures” and techniques that allow systems to be integrated
collaboratively and companies (supplier – customer) to be integrated with each other
– Additive manufacturing – The Industry Observatory 4.0 of the Polytechnic University of
Milan recognises Additive Manufacturing as one of the innovative “intelligent operational

SLS – Selective Laser Sintering

Selective Laser Sintering (SLS) is an Additive Manufacturing technology based on the powder bed fusion – PBF.
The material used by SLS technology is a set of powders with controlled particle size that are
deposited in a uniform layer inside the processing chamber.
These powders are sintered by applying thermal energy provided by a high-power laser beam (two lasers in the case of machines with a larger print volume) that allows the particles to be sintered locally. The process is iterated up to the manufacturing of the part(s).
SLS technology has been commonly used in rapid prototyping for over twenty years and it is
subject to evaluation and use in serial production thanks to its high productivity compared to
other 3D printing techniques.
Among the principal advantages of this technology there is the geometric freedom.
By exploiting the bed of unfused powder as a support, SLS technology allows you to create parts with freedom of design. The absence of supports for the construction of the part allows to
increase productivity and reduce post-process costs.

 SLA – Stereolitography

Stereolithography (SLA) is a 3D printing technology based on photopolymerization of a resin
contained in a tank, through the action of a laser beam that emits an ultraviolet radiation.
It is used in rapid prototyping where high precision and high surface quality are required.
Thanks to stereolithography, it is possible to produce prototypes in transparent material.

features make it suitable for many applications: car lenses and lights, masters for silicone moulds, wind tunnel tests etc.

Products printed using SLA have an excellent aesthetic effect with regard to surface finishes such as painting and metallization by means of a galvanic process.

DMLS – Direct Metal Laser Sintering

Direct Metal Laser Sintering (DMLS) or Selective Laser Melting (SLM) represents the Additive
Manufacturing for metallic parts.
Similarly to SLS, DMLS / SLM techniques are based on the concept of powder bed fusion (PBF).
These techniques make it possible to build metal parts starting from a powdered raw material that is sintered or melted.
The pieces made with DMLS / SLM have mechanical properties equal to or superior to those built with traditional techniques and they can be used in rapid prototyping or as definitive components for serial production.
Both technologies offer remarkable precision and the materials are suitable for numerous post-
processes such as CNC machining, heat treatments, surface treatments both aesthetic and

FDM – Fused Deposition Modeling

FDM (Fused Deposition Modelling) is one of the most common additive manufacturing

Parts are constructed layer by layer by depositing a thermoplastic that comes from the fusion of a filament. Parts produced with this technology are resistant to heat, chemicals, mechanical stress and environmental variables.

Thanks to the very high resistance and excellent thermal stability of our materials, it is possible to build products for the aeronautics, motorsport and aerospace sectors.

CNC –  Mechanical processing

Realization of parts using 3 and 5 axis machining centres, with the possibility of processing:
• Epoxy resins and PU
• Aluminium

Lamination of composites

Realization of parts through autoclave lamination of:
• Carbon fibre
• Fiberglass

Vacuum Casting

Realization of parts through vacuum casting of polyurethane resins inside silicone molds.
