That should work out well.
I have been checking out this new Creality Ender-5 Max for some prototyping, which has just hit the market. It has a 400 x 400 x 400 build area and it looks like it can handle the technical filaments like PA6-FG, PA6-CF, and PAHT-CF with it's high(er) temp print head and heated chamber.
What filament do you expect to use for the final product?
