still thick when mixing the two parts, it implies that the white part – the epoxy may be needed more in the mixture and it may be added as desired. This mixture which is now ready to be put into the syringe and printed in the fab at home machine. Flat and curved layered parts are then printed one by one on top of the support structures printed earlier. A flat layer part being printed in Fig 3.12. Fig 3.12 A flat layer part being printed on the Fab at home machine Flat and curved layer models are then printed on alternative support structures while modifying speed of deposition. Sample flat and curved layer printed parts shown in fig 3.13. 82
machine Fig 3.13 Flat and curved layer parts being printed side by side on the Fab at home As a variation to the standard part, and for statistical analysis the curvature of the main part is increased slightly creating a second part, Model 2 with height 11mm. The length, width of the new part is kept the same as Model 1. A change in curvature would mean that there would be an increased gap between the bottom surface and the top surface of the main part and hence a new support structure model is created to support this change. Fig 3.14 shows main and support structure model of Model 2. Fig 3.14 Model 2 – Main part and support structure model Similar to the previous model, support structures are prepared first and the main part is then printed over them by changing parameters like style of deposition – flat or 83
