I'm working on a project where I have to design a Cartesian 3D concrete paste printer, in which I aim to make the build plate fixed with a 500 mm × 500 mm build area. But I'm confused as to how I should implement the motion of the Z-axis. I am thinking between:
- Using a Z-axis that moves the entire X and Y frame.
- Using an independent Z-axis that moves by itself only without the X and Y frame.
What are the differences between the two methods in terms of:
- Ease of design & assembly
What design is more reasonable from a mechanical design point of view?
An example of the first method is the TITANXY (Fixed Build Plate, Quad Z Screw, CoreXY)
An example of the second is the Maximus 3D Printer
