How to Make Custom Sublimation Phone Cases

Personalized phone cases are all the rage these days. But why spend big bucks on a pre-made design when you can make your own custom case using sublimation? Sublimation is a printing technique that allows you to transfer a design onto a substrate (in this case, a phone case) using special inks and high heat. The end result is a beautiful, full-color design that won't fade or chip over time. Plus, making your own phone case is a fun DIY project that you can do at home!

What You'll Need

To get started, you'll need the following supplies:

- A Sublimation Printer:

This type of printer uses specially-formulated inks that are designed to withstand high temperatures. Not all printers can handle sublimation inks, so be sure to check compatibility before making your purchase.

- Sublimation Paper:

This paper is coated with a polymer that helps the ink to bond with the substrate. You can find sublimation paper at most craft stores or online.

- Heat Press:

A heat press is an appliance that applies heat and pressure to your project, allowing the ink to transfer evenly. If you don't have access to a heat press, you can use an iron instead; just be sure to use the steam setting and place a towel over your project to protect it from direct contact with the iron.

- Phone Case:

For this project, you'll need a white or light-colored phone case that is made of polycarbonate plastic. Once again, you can find these at most craft stores or online retailers.

Creating Your Design

Once you have all of your supplies, it's time to create your design! If you're not confident in your design skills, there are plenty of phone case mockups available online that you can use as a starting point. Just remember to flatten your design before printing so that all of the layers are merged into one image. Once your design is complete, print it out on your sublimation paper using your sublimation printer. And your sublimation phone cases will be ready.

Applying Your Design

Now it's time to apply your design to the phone case. If you're using a heat press, set it to 400 degrees Fahrenheit and preheat for 5 minutes before adding your project. Place your phone case face-down on the bottom plate of the heat press, then top with your sublimation paper (design side up). Close the heat press and let it run for 60 seconds. If you're using an iron instead of a heat press, set it to the steam setting and preheat for 5 minutes before beginning. Place your phone case face-down on an ironing board and top with your sublimation paper (design side up). Cover with a towel and press down with the iron for 30 seconds before moving on to another area. Repeat until the entire design has been transferred.

Once your design has been transferred, allow the phone case to cool completely before handling further. That's it—you're done! Now you have a one-of-a-kind phone case that was made entirely by you.


Sublimating phone cases is a fun and easy way to create unique personalized cases for yourself or as gifts for friends and family members. All you need is a few supplies and some creative flair! So what are you waiting for? Give it a try today!
