structure. Honeycomb scaffold architectures were made of layers of directionally
aligned PCL microfilaments within a geometrical 3D structure. Analysis of the
mechanical properties contributed to a better understanding of the anisotropic nature
of different designs. Examination of the mechanical deformation indicated that the
porous PCL scaffolds demonstrated stress–strain behaviour highly similar to that of a
typical porous material undergoing compression. The mechanical properties were
found to be generally dependent on its porosity, regardless of the lay-down pattern
and channel size which is in parallel with theoretical concepts on the structure–
properties relationships of porous solids.
One of the primary goals of any rapid prototyping system is the production of metallic
prototypes for functional applications and testing. In 1995, M Gruel et al [11]
developed a new rapid prototyping process known as the “multi phase jet
solidification”. The basic idea was to extrude material with low viscosity through a jet.
The material was supplied in different phases as a powder-binder mixture. The
material is heated above its solidification point, squeezed out through a nozzle by a
pumping system and deposited layer by layer. The part is then sintered and
analyzed for its properties.
Different requirements of this type of rapid prototyping system have been researched
upon for its quantification purpose. In order to model and optimize the RP process, a
virtual reality system was proposed by Choi et al [12]. This system‟s main idea was
to improve the quality in a product development cycle by reducing the manufacturing
risks involved and in result it reduced the cost factor of the repetitive design, build
and test cycle. This system primarily involves in designing and simulation of the rapid
prototyping process in a virtual system which helps in getting various parameters of
the system like built time, accuracy, part quality, hatch distance and layer thickness.
Hardware and software of the RP system are two major areas which are always
concentrated upon for improving the part quality of the parts produced by the FDM
process.
To improve the finish of the parts produced and to be able to use more variety of
materials like ceramic materials, a lot of attempts has been made to improve the
hardware part of the process. To prototype a variety of ceramic components, a new
