    Senior Project Viability

    I am an engineering student in the US and my senior project is a new type of hotend. I am curious what the market looks like for my proposed product. I am hoping to get feedback as a potential user and, ideally, some advice on how to research it's viability as an actual product.

    I cannot disclose anything else, but I have the following stats:
    heating time (22C-210C) ~12 seconds
    power requirements 3-15 watts
    size - comparable to existing heating blocks

    I am curious what kind of price you might be willing to pay, how likely you might be to purchase it as a retrofit (assuming compatible mounting method), and if there is some place where I can get more information about the market.
    Thanks for your help!

    People would pay about what they pay for current hot ends. Looks like the only advantage you are claiming is heating time. That means you have a low thermal mass. Because hotends are activated once and kept hot during the whole print saving 60 seconds in warm up time on a 4 hour print does not mean much. Some people might be concerned about the low thermal mass causing cold spots when extruder flow changes rapidly. The PID controller would also need a shorter cycle time to prevent over/under shoot. Seems like you would need to do a good job selling advantages (assuming there are some) and how to configure for proper control to sell at a premium price.
