How to Make Custom Phone Cases

The custom phone accessories market is exploding, valued at $25.51 billion in 2024 and projected to reach $53.33 billion by 2033. The biggest share is of custom phone cases. Wildly popular among Gen Z, who treat their phones like personal billboards.

The margin potential in this business is massive. Plain blank cases cost $1–2 in bulk. Scroll through Etsy, and you'll find those same cases, customized with a design, selling for $15 to $36. At mall kiosks, that’s even higher.

Who wouldn’t want to enter this lucrative venture? Surprisingly, getting into custom phone case production isn't complicated. You don’t need industrial equipment or a large warehouse space. What’s required then?

Read through this guide to learn how you can create custom phone cases at home with minimal setup, and launch a side hustle that scales without burning cash.

What Do You Need to Make Custom Phone Cases?

In general, there are multiple ways to make custom phone cases. For instance, one approach is hand-painting or decorating with stickers, rhinestones, or decals. Another involves printing techniques like sublimation,or UV printing.

Since the focus here is on the commercial side, we'll concentrate on UV printing: a method that not only offers quick customization with high-quality, textured prints but is also incredibly powerful at economies of scale.

Best Types of Phone Cases for UV Printing

Inherently, UV printing is very flexible in terms of materials and surfaces it can print on, and that's one of the reasons it's gaining popularity across different industries, from signage to promotional products.

However, you'll need to be strategic about your choice. Because of flexible materials, ink may not stick properly, and may require surface prep or specialized inks.

Some of the best phone case options are:

Polycarbonate (PC) has a rigid, smooth surface that provides an ideal canvas for UV printing, producing sharp, vivid results with excellent adhesion. PC cases offer military-grade drop protection and top-level impact strength.

TPU (Thermoplastic Polyurethane) has a non-porous surface, perfect for high-resolution UV printing, and its flexibility offers better shock absorption than rigid polycarbonate. TPU is highly customizable and supports various printing options, including UV printing. However, clear TPU cases can show visible yellowing within two to four months due to UV exposure and skin oils.

Silicone is possible but requires careful surface preparation and specialized primer layers to achieve reliable bonding. Even with proper preparation, UV ink on silicone may not achieve the same adhesion longevity as on TPU or polycarbonate. In the market, you may find some flexible UV inks to tackle such materials.

Hybrid Cases (PC + TPU). Many commercial phone case makers combine materials, typically a polycarbonate back panel (for printing) with a TPU bumper (for shock absorption). This gives you a PC's superior print surface with TPU's impact protection.

Tools & Materials Needed

For customizing phone cases with UV printing, you'll need:

1. Blank Phone Case/s

Choose from the materials mentioned above. Blank cases are widely available from suppliers like Alibaba, Amazon Business, or specialty case wholesalers, typically costing $1–2 per unit in bulk.

2. UV Printer

This is your core investment. We suggest the xTool UV Printer, purpose-built for this workflow. It offers dual print heads for enhanced printing speed, precise auto focus and design placement, exceptional color accuracy and vibrancy, and a compact footprint suitable for home studios or small shops.

3. Design Software

You can make a design from scratch using Adobe Photoshop, Illustrator, or Canva, GIMP, or source a pre-made design from the Internet. Another interesting option is AI-powered design. Use xTool's AIMake tool to construct print-ready files via simple text prompts.

How to Make Custom Phone Cases Step by Step

Now, with tools in hand, all you need is to follow these steps:

Step 1: Place the Phone Case Inside the UV Printer

Place your phone case with the backside facing up (inverted) inside the printer bed. The white foam insert that comes inside the case can stay in place. The foam provides support and helps catch any ink overflow around camera cutouts and buttons, ensuring clean edges.

Step 2: Create or Import Your Design

Once the case is placed inside the printer, its live preview appears in XCS (xTool Creative Space software). You can resize, rotate, and position your design to fit the printable area.

You are not essentially required to create a file with precise phone cutouts; the software overlays the case outline, so you can see exactly where cameras, logos, and edges fall. If pre-made templates or skins are available for your phone model, great, use them. If not, you can eyeball the placement and adjust on the fly.

Your design could be full-coverage print (edge-to-edge graphics), a logo, personalized text, or a mix of all.

Step 3: Adjust Print Settings

Before hitting print, configure your settings in XCS. Although preset settings are available for most materials, you can cross check too if any adjustments may be needed.

If your design includes transparent areas or you're printing on a clear case, enable the white ink underbase layer. This prevents colors from looking washed out.

Step 4: UV Print the Phone Case

Hit the Start button, and the magic begins. The printer deposits UV-curable ink layer by layer while simultaneously curing it with UV LED lights. The entire process takes anywhere from 2 to 8 minutes, depending on design complexity and quality settings.

UV Printing vs Sublimation vs Stickers for Phone Cases

Besides UV printing, sublimation and UV DTF/plain stickers are also common ways to customize phone cases. We wouldn't argue about what's best since each method has its own place depending on your design goals and workflow.

Sublimation is transferring dye-based ink onto a polymer-coated surface using heat and pressure. It's particularly useful if you're aiming for a full-color design that even covers the sides of the case. Since sublimation requires heat pressing, specialized presses like the xTool WonderPress are ideal. The WonderPress uses advanced vacuum-suction technology to wrap transfer film entirely around 3D objects, allowing you to sublimate vibrant, full-wrap designs onto curved items like phone cases with edge-to-edge coverage.

Stickers can be applied directly to phone cases without any printing equipment. This may be the best option if you're looking for sparse, minimalist designs rather than full-coverage prints (small logos, icons, or accent graphics). UV DTF stickers are pre-printed, peel-and-stick decals with a glossy, durable finish.

UV printing is ideal if you want to achieve minimalist designs, full-color graphics, or 3D textured effects, all with the same machine. It can be directly applied without any heat press, pre-treatment, or transfer film.
