What is the difference between Ender 3 V3 and V3 SE?

The Ender-3 V3 is the more capable, faster, and more premium printer; the Ender-3 V3 SE is the budget-friendly, easier-entry version. If the price gap is reasonable, pick the Ender-3 V3 for better performance and longevity. Pick the V3 SE if you mainly want a low-cost first 3D printer for PLA/PETG and don’t need top speed or premium mechanics.
