The support structure‟s dimension is 28mm L x 20mm W x 4.8mm H. Under strict<br />

parameters and quality control, the parts are printed in the fab at home machine<br />

using silicon and the output result is shown in Fig. 3.11.<br />

The same support structure would be needed for both curved and flat layer and a<br />

number of parts would be required for testing the strenth, hence a good number of<br />

support parts may be printed at a stretch, side by side so that they are ready to go,<br />

to be used for printing on top. Once the desired number of support structures are<br />

created, they are left to cure overnight so that main parts can be printed the next<br />

day. The main part which would be used in this research paper to compare the<br />

strength, needs to be printed under the same strict conditions and quality control the<br />

material is to be printed. The material for the main part would be Fabepoxy, which is<br />

to be prepared first.<br />

Fab epoxy comes in tubs of two – a epoxy and a hardner. Equal quantities of epoxy<br />

and hardener are taken, measured and then mixed together in a mixing bowl. The<br />

epoxy and the hardener are first in pure white and dark brown color respectively to<br />

start with, and they are nicely mixed till they reach a light brown to pink color. It is<br />

also made sure that the material is in fluid / paste composition which can easily flow<br />

through the nozzle attached at the end of the syringe. In case when the material is<br />
