>>111298763d printed rockets are easier to make, store, set up and fly, but they have only two major drawbacks:
1. They MUST be stored loaded and heavy, which makes making, storing, setting them up and flying them a royal pain in the ass
2. they're enormous fireworks that will explode at a moment's notice, which makes storing, loading, setting them up and flying them a royal, dangerous, pain in the ass
combined this means that solid rockets are always better and cheaper and easier right up until the rocket starts to too heavy to put in the back of a pickup truck, which is when all that extra complexity of liquid fuels starts to make sense
coincidentally, it's also about when the performance advantages of liquid fueled rockets start to kick in
