Today I performed a test print of the insulin pump. Due to the reality of the pump shell being injection moulded and how thin and compact the device was. I was concerned over thickness of the walls and how they could be replicated by 3d printing. Therefore a test print was necessary. Due to previous models being made out of  foam there were also sizing discrepancies so by moving forward with 3d prints I will have a far greater accuracy and reference to the real form.
