Abstract

Additive Fabrication technologies are well known from the last two decades.
In that time Additive Fabrication technologies have evolved from strictly
prototype part production into an option that can also be used to produce
end-user parts. With development of Additive Fabrication machines capable
of producing metal parts, a complete substitution of conventional metal
casting technologies is possible. However, direct Additive Fabrication of
metal parts is still not time/cost effective when producing large volume
parts, and nowadays there is still lack of materials that can be used on
those machines. This paper presents a method how a conventional sand
casting process can be assisted by Additive Fabrication technologies. A
sand mould pattern is produced by Selective Laser Sintering. Additive
Fabrication is also used in direct manufacturing of cores.
