Question: what is the difference between the ender 3 and ender 3 pro?
Answer: For starters, the Ender 3 Pro has been redesigned with a more sturdy, 40×40 aluminum extrusion for the Y-axis base. ... Another aspect that makes the Ender 3 Pro superior is the upgraded Meanwell Power Supply Unit (PSU), which is thinner, quieter, and all-around better than the version featured on the original Ender 3.
