It is now becoming possible to produce multi-material objects with
functionally graded material. There are several RP machines which have the
capability to make multi-material objects. Application of parts with
heterogeneously and anisotropically varying material properties include
weight reduction, improved structural and other mechanical properties and
the promise of embedded sensors. For example prosthetic implants are
designed to have superior wear resistance, superior bonding with bones,
maximum strength, and to exhibit bio-compatibility.
The conventional manufacturing processes did not have the capability to
produce heterogeneous objects. As there was no need, the solid modelers had
the capability to model homogeneous objects only. We at NIST are working on
representation of heterogeneous objects.
It would be interesting to know the RP processes which have the capability
to produce multi-material and functionally graded material objects. I would
like to hear from you the name of the processes which can make such parts
and a brief description of the process. SDM can make multi-material parts
and embedded sensors. I would compile all your responses and sent back to rpml.
Thanking you,
Sanat
