Form Development

form development

With a knowledge of the form size and components contained within, I can now move forward developing the shape improving its aesthetic appeal and giving the actual pump and monitor some design value, features.

3d Print test

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.

Thinking About Pump Technologies

I have been analysing different pump technologies and sterility for transporting the insulin. I have finally decided on the technology and best configuration available. I have been studying different piezoelectric pumps and contacting manufacturers. Using a cartridge based or standard piezoelectric pump in a cartridge form with the needle mounting element all in a disposable part enables the actual pump body to contain a far greater chamber for insulin as well as the battery and circuit board parts. I am now moving on developing the form of the pump thinking more about its appearance and interaction with a charging hub.
