1. Moulds &
casting

2. Introduction
• Traditionally in Industrial Design and Sculpture
students and professional artists still use clay for
modeling and plaster for moulds. This method
requires some skilled knowledge in handicrafts.
• In some cases (according to mould design) the
moulds are reusable and many casts would be
made.

4. Clay modeling and final
resin cast for prototypes

5. Even today, also the interior is
made this way

6. Sculpture modeling in clay
• It requires a whole understanding of the
form to be represented. Several previous
studies are drawn or photographed.
• This material is so sensitive that allows
many modifications.
• Most schools of art and design includes
core courses with this procedure.

8. Plaster Moulds

9. Simplified process
• The traditional method allows us making
large works in sections (see PDF doc in
Spanish).
• For a faster and accurate registration
urethane, silicone or liquid latex are
used.
• With these materials we can obtain more
copies than with plaster moulds

19. Is a CAM software application that
accepts IGES, DXF* and STL files
exported from most popular
industrial 3D CAD software
programs. It is used to generate
proportional 3D scaling, identify
milling direction and to
automatically generate and display
the tool path. MODELA Player 4
supports tool changing when used
with the Automatic Tool Changer
(ATC) and automatic side cutting
when used with the Rotary Axis
Unit. It can also be used for 3D
engraving.

21. Actually, replication is possible in a
short term using a 3D scanner and
a 3D printer even in different scales

25. CAD for 3D moulds

26. Art
A set of attached parts is used, hollow inside but with the
details and impressions in negative for the future solid
Rigid and flexible molds, molds depend on the shape of the
part to duplicate, determined by the degree of complexity of
the details and the its symmetry.

27. Industry
Injection Molding
Semi-continuous process which involves injecting a molten
state polymer or ceramic in a closed mold through a small
hole
Injection molding is a very popular technique an example of
this is the interlocking pieces of lego.
The popularity of this method is explained with the versatility
of parts that can be obtained, the scalable design from rapid
prototyping processes, high levels of production at low costs

28. Medicine Reconstruction of the Pinna
Microtia
Selecction of Cartilage Silicon made mold Operation and post
operative results
Congenital malformation of variable
severity that affects the outer ear.
Usually affects the proper hearing

29. Medicine
The use of a mold as a support for
the framework of autologous
cartilage in auricular reconstruction
for microtia can achieve an
adequate definition of the details
and build one ear similar to the
oppossite one, with better cosmetic
results.
