For prototyping purposes, I just recently purchased the following items, for a total of $252.34 (including $62.37 in shipping).

Humanoid Head with Camera & RGB Eyes Hexapod Body (includes battery) EZ-B v4 Wi-Fi Robot Controller

Just for the purpose of discussion, suppose that I am lucky enough that the first order placed with my future startup business is for 25 of these heads along with an abundance of back-end proprietary software required to process data generated by each of the bots. That means passing along hardware costs totaling about $6,300. So I’m wondering about cutting those costs somewhat.

I imagine there would be some volume discount available for, say, a quantity of 25 of each of the three items above. But what about saving on the cost of the humanoid heads? If I were to purchase a $2,000 3D printer for say $2,500, how many of the heads would I need to print in order to offset the cost of the printer and materials? Any guesses?

On the other hand, choosing in-house production of heads means that I would need to piece-meal order the other items that come in the Humanoid Head with Camera & RGB Eyes kit. Woof!
