I've seen PLA pumps on youtube and they work, but you're probably looking at high pressures if you want the rocket engine to work. First of all I suggest looking into the more 2d versions of pumps (pic related) because they're both easier to model and make. How did you make the aerospike? BTW it's a turbopump if it's powered by a turbine.
