The Creality Ender 3 is a great printer, especially for its price point. However, if you’re looking to buy one, you may have heard mixed reviews on what is the actual vs advertised Ender 3 bed size.
The Ender 3 has an advertised and usable print area of 220 x 220 mm. However, the size of the print build surface actually measures 235 x 235 mm. That means an astonishing 14% of the print bed is going unused!
Keep reading to learn more about why this is and what you can do to fix it.
So now we know that the Ender 3 bed size is 14% larger than what’s being used. But now you may be asking yourself, why is that?
Here are a few reasons why the actual Ender 3 bed size would be larger than the usable area:
Tired of losing that extra 14% of build space? We have your solution. First, instead of using and fighting with the binder clips that came with the stock Ender 3, you can change how the print bed attaches to the frame. There are two options, change the clips or change the print bed.
Now that the print is clear of the bulky binder clips, let’s talk about the second step: programming your 3D printer to actually use this space. To unlock your Ender 3 bed size’s true potential, you’ll need to update the mainboard computer’s firmware. There are two essential steps to opening a larger bed size:
Creality decided to set the firmware with the usable Ender 3 bed size to be smaller than the actual size of the build platform, at 220 x 220 mm. When you consider the tolerance and bed fastening, this actually sounds logical. But does it really need 15 mm on each edge?
Technically, the answer is “no.” A 5-mm lip should be sufficient. Therefore, we’ve reviewed how to achieve a 230 x 230 mm print area by modifying the 3D printer’s print bed and firmware.
We don’t recommend setting the Ender 3 bed size to the full 235 x 235 mm, as printing right on the edge is likely to cause issues. However, feel free to play around with it and find what works best for you and your Ender 3.
As always, happy printing!
