ADDITIVE MANUFACTURING
Technologies used to produce small batches of components, including complex objects, in
a very short timeframe. To be used for drastic reductions in TIME TO MARKET
SLA - Stereolithography
The material is a laser beam-hardened resin
• Standard
• High resistance (gray)
• Transparent
• Similar characteristics to Ceramics
(high thermal performance 180 to 200°C, can be used with hydrocarbons)
SLS - Polystyrene
Used to create wax masters for casting.
SLS - Sintering of powders
The basic material is a PA (nylon) powder. To create the object, the
powders are sintered by a laser beam, one section at a time.
The dimensional tolerance is normally 1-2/10 mm for objects up to
100 mm size.
The PA powders can be used together with the following additives:
-
-
Glass fiber loads to improve resistance to wear and tear and heat
Metallic loads (aluminium) to increase machinability for
modifications or adaptations. The material retains its isolating capacity
and acquires good heat conduction characteristics.
Additional treatments: It is possible to carry out
impregnations in order to close the cavities in the
sintered resin and subject it to a vacuum or pressures of
up to 7 bar.
Painting, chrome and aluminium plating.

FDM - Fused Deposition Modelling
The material is a 0.2 mm diameter in ABS, PC, Ultem wire (flame-retardant certificate). The wire is melted
by a mobile nozzle that generates the object section by section. The prototypes may be coloured as
requested (RAL). Dimensional accuracy varies depending on the size of the object. On average, it is
possible to achieve an accuracy of +/- 0.1 mm.
Vacuum Casting
By using a “Master” prototype
in SLA or SLS (depending on
the size of the object) it is
possible
to
create
the
negative in a vacuum casting
Silicone resin mold. The
resulting silicone mold is
used to vacuum create
castings using resins that
simulate the characteristics
of most widely available thermoplastics
Resins for use at temperatures up to 180°C or with glass fiber
loads.
It is possible to reproduce the full range of
RAL colours and degrees of transparency.
Other resins can be used to produce
coloured and transparent soft (rubberlike) parts with hardness between 40 and
70 Shore.
POLYJET polymer jet 3D printing
This material is a UV-solidified polymer resin. In the same way as stereolithography, it can be used to create patterns
with a high degree of dimensional accuracy in a very short timeframe. Both rigid and soft materials are available for
testing and product checks.
