The 3D Sublimation Process: An Overview AU

The 3D sublimation process is a sophisticated method for transferring dye onto three-dimensional objects, revolutionising the way custom designs are applied. At CustomLogoCases, we leverage this advanced technique daily to produce high-quality, bespoke phone cases and other custom items. Whether it’s a company logo or a complex design, 3D sublimation allows us to deliver vibrant, long-lasting results that adhere seamlessly to various surfaces.

3D Sublimation Overview: What Is It?

Unlike traditional sublimation, which is limited to flat, two-dimensional items, 3D sublimation opens up new possibilities for customisation. By using specialised equipment, we can imprint designs onto objects with curves and contours, such as mugs, phone cases, and promotional products. This process ensures that every detail of your design is captured, making it perfect for creating truly unique and personalised products.

The 3D sublimation process allows for patterns to be applied to every surface of an object. The term “sublimation” refers to the process where a solid dye is turned into a gas, which is then applied to the desired object using heat. The dye becomes absorbed directly onto materials such as clothing, mugs, phone cases, and more.

How It Works

A 3D sublimation heat press typically costs around a thousand dollars for machines from China, which are usually red and black. These machines use a medium called sublimation paper. The process involves wrapping the special sublimation paper around the object and then using an air-forced vacuum on a silicon pad to ensure the paper adheres tightly to the object. The procedure differs if an oven is used instead of a press.

Types of Sublimation Paper

A major distinction in 3D sublimation is between processes that use paper versus those that use film. Using paper for 3D sublimation can be problematic, particularly with rounded corners. The paper can sometimes cause the image or pattern to not fully adhere to the object, or creases in the paper can show up in the final product.

For instance, phone cases for devices with straight corners, like many iPhones, typically work well with paper systems. However, phone cases for devices with rounded corners, such as many Samsung models, can pose challenges. Sources suggest that using a vacuum with heat may result in poor alignment and colour issues, with only one case being produced per cycle.

While paper-based 3D sublimation systems are often more affordable, they may experience higher failure rates—up to 90%—with items that have rounded edges. As a result, companies using paper-based processes may offer lower prices for custom-made items like phone cases and mugs, but there might be a trade-off in quality.

Types of 3D Sublimation Film

An alternative to using paper is employing a 3D sublimation oven with film. This method is more expensive, with ovens costing around $10,000 or more, depending on quality. The advantage of using film is that it sublimates directly onto the blanks, eliminating the need for the extra step of printing and wrapping paper around the object.

Film-based systems are generally more efficient and faster than paper-based systems. As such, smaller operations often use paper, while larger operations that produce high volumes of products daily may opt for film. Although opinions vary, many in the industry regard film-based systems as superior to paper-based ones.

Pros and Cons of 3D Sublimation

Like any manufacturing process, 3D sublimation has its advantages and disadvantages. The suitability of this process depends on the specific needs of the project and other factors.

Pros of 3D Sublimation:

• All-over Designs: This method allows for designs to wrap around the entire object without needing separate presses for different sides.
• Good for Customisation: Ideal for smaller production runs, particularly with film systems, which require less labour and can offer high-quality results at a reasonable cost.
• Variety of Colours: Offers extensive colour options without additional costs for using multiple colours, provided the process quality is high.
• Material Flexibility: Suitable for a range of materials, including garments, phone cases, cups, and more.

Cons of 3D Sublimation:

• Imperfections: Potential for imperfections, especially around the edges and with vacuum and paper systems, which may result in weak transfers or errors at the corners.
• “Ghost” Effects: Some machines, particularly paper-based ones, may leave unwanted extra images or ghosting, depending on the quality of the process used.
