I don't understand the question.  Do you want to change one of the core's during a print?  Or do you want to change the nozzle on the core (not during a print)?


The AA core is slightly better at not leaking.  The BB core doesn't have a crack for the PVA to caramelize in.




so where do you find this picture about the difference between AA and BB?I can’t find it at the official website.

Thank you.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
