May be this question is too silly to this forum but... here it goes.

As everybody knows, the cost of injection moulds is high. A plastic
injection molded piece is feasible only if thousands or thousands
of parts are to be produced.

This is a real problem whre only some dozens or even hundreds of
parts are to be made. This is the case, for example, of HO scale
model trains, cars and locomotives.

The variety of model cars and locomotives in the HO scale here in Brazil
is very scarce. The main cause, of course, is the high price of the
injection molds...

A group of rail fans approached me and asked if RP could be used for
the production of small series of specific model locomotives and
cars in the HO scale. As this technology is very new to me, I do
not know if this is feasible, so I am forwarding the question to the

Nevertheless, I think that some toys eventually used RP during its

Thanking you very much in advance!

All the best,
