If you have a 3D printer, I don’t see why you shouldn’t try making some custom keycaps for your mechanical keyboard. It’s a very simple way to get a unique look on your keyboard and make it much more enjoyable.

If you wonder how good they will be or how they are better than other keycaps, I can help you with that. I will go through an overview of these keycaps so you can get the idea and decide whether you want to go for them or not.

3D printed keycaps overview

There are several things you can look at when it comes to 3D printing your mechanical keyboard keycaps. Also, it’s not all good. There are some limitations or drawbacks to consider as well. So, you have to go through all that to decide on printing your keycaps or buying them pre-made.

Let’s get going with the considerations.

Why use 3D-printed keycaps?

Well, the apparent reason for 3D printed keycaps is enhancing the look of your keyboard. There is no typical benefit in terms of performance or functionality when you use printed keycaps. It’s solely made for the looks of your keyboard.

Let’s say you are planning to build a custom keyboard or want to customize the look of your keyboard. You can use some 3D printable designs for keycaps and print them out to style up your keyboard. This way, you end up with a unique-looking keyboard that might not be available as a pre-built version.

Adding to that comes the factor of likeability. For example, if you are a fan of Star Wars, you can get some custom printed keys based on the Star Wars theme. This will make your keyboard look much more exciting to you as well as others.

It’s also a great way to customize the keyboard if you play a particular game professionally or just for fun. You can print out the in-game functions as logos on your 3D keycaps. This makes the keyboard look unique and makes it easy for you to recognize the key bindings of a game.

For example, if you play a lot of Valiant, you can use custom-made keys based on your agent abilities. This way, you won’t have to worry about pressing the wrong button and using the wrong ability in the middle of the game.

When and where should you use these keycaps?

Now, there are several things that you should keep in mind when you choose to go for these types of keycaps. While it adds a unique touch and makes your keyboard look interesting, don’t replace all the buttons on your keyboard with these keycaps. Only use these kinds of keycaps for specific purposes.

It would help if you didn’t replace the A-to-Z letter keycaps with any 3D print keycaps because those are functional. You have to make sure those keycaps are your normal keycaps. Because with 3D printed keycaps, you won’t be able to type as fast as you would do with regular keycaps.

So, the best method is going for a blend of keycaps. You can use the regular keycaps for all the letters and numbers. And you can get 3D printed keycaps for unique buttons.

For example, many people use 3D printed keycaps in their “Esc” key on the keyboard. You can also do this for other functional buttons like the backspace, enter, shift, ctrl, etc. And if you have macro buttons on your keyboard, you can replace them with these keycaps.

In one particular instance, you can use printed keycaps for the letter keys for specific games. If you don’t do too much official work or have any typing-related work, then you can replace some letters with the key bindings of your favorite game. Other than that, it would help if you only used replacement keys for letters and numbers.

Drawbacks and limitations of 3D printed keycaps

There are some limitations to 3D printable keycaps, which are also the limitations of 3D printing as a whole. The first thing is coming up with the filament material or the material for printing those keycaps.

There are two popular choices here; you can either go for FDM or go for DLP resin. So, if you have a filament printer, you will have to go with FDM, and if you have a resin printer, you can go with DLP resin. The limitation here is that you can’t go with FDM with a resin printer and vice versa.

Among these two choices, resin is a better material than FDM. There are two reasons for that. The first one is that you get cleaner and smoother keycaps right out of print with resin. Whereas for FDM, you have to do some cleaning and sanding to make them better.

Secondly, if you are printing multiple keycaps, then resin works much faster than FDM. With resin, you can print various keycaps at the same time. While with FDM, the more keycaps you print, the more time it will take.

The final drawback is that you will be doing a whole lot to get your hands on some 3D-printed keycaps.

First of all, you have to look for the 3D printable files or design them yourself. Then going through all the printer settings and filament material management can be pretty troublesome. After that, you may need to do some clean-up work on the printed keycaps, which adds up to work.

It feels too much work for some keycaps on your mechanical keyboards. Because you can easily find various themed keycaps out there to enhance the look. However, to make it unique and customized cost-effectively, 3D printing probably is the best bet.
