The Longer ePrint is the world’s first dual-printhead personal UV printer designed to turn a desktop workspace into a high-speed production hub.
By utilizing a 12-channel architecture, it solves the two biggest frustrations of desktop UV printing: agonizingly slow 3D texture stacking and the inability to print on flexible apparel.
It is built for small business owners, Etsy creators, and DIY artists who need professional-grade customization across more than 300 materials, ranging from rigid acrylic and wood to curved mugs and cotton T-shirts.
For those looking to scale a creative business, the Longer ePrint provides the capabilities of a industrial-grade machine at a fraction of the size and cost.
Key Takeaways
- Longer ePrint’s dual-printhead, 12-channel system directly targets the biggest desktop UV printing bottleneck: slow production speed, especially for 3D texture work.
- Its hybrid UV and DTF capability makes it useful for creators who want to sell both rigid custom products and apparel transfers from one workstation.
- Support for 300+ materials, high-gap printing, and rotary/conveyor modes gives small businesses more flexibility with irregular, curved, and transparent objects.
- Built-in AI tools reduce design and alignment time, helping nontechnical users move from image creation to finished prints faster.
Longer ePrint Dual-Head Architecture: Why 12 Channels Matter
Most desktop UV printers rely on a single printhead, which creates a bottleneck when trying to build depth or handle complex color layers. The Longer ePrint breaks this limitation by integrating two independent printheads and 12 dedicated ink channels.
This isn’t just a marginal improvement, it represents a fundamental shift in how quickly a project moves from a digital file to a finished product.
In standard flat printing, the dual-head system operates 1.5 to 2 times faster than single-head competitors, effectively cutting production time by 50% to 70%.
However, the most dramatic advantage appears during 3D texture printing. Because the system can dedicate six channels specifically to white ink, it can stack layers simultaneously to achieve a 3D relief speed that is theoretically six times faster than traditional methods.
This speed makes “tactile branding”, where customers can actually feel the texture of a logo or design, commercially viable for small-batch production rather than just a slow experimental feature.
The machine is constructed with a solid aluminum-alloy body and transparent acrylic panels, weighing approximately 35 kg.
Despite its compact footprint of 640 × 460 × 330 mm, it provides a substantial usable work area of 310 × 420 mm, large enough for medium-sized projects and batch processing of smaller accessories.
UV and DTF Printing in One Longer ePrint Workflow
For many creators, the choice between a UV printer for rigid goods and a DTF (Direct-to-Film) printer for apparel is a difficult financial decision, often requiring two separate $1,000 investments. The Longer ePrint eliminates this divide by supporting both processes in a single device.
One six-channel printhead is dedicated to standard UV printing for items like phone cases, acrylic, and glass.
The second head can be configured for DTF inks, allowing you to print high-definition transfers directly onto film.
Once printed, you simply apply hot melt powder, cure it, and heat-press the design onto cotton, polyester, or canvas.
This hybrid capability means you can sell custom-printed mugs and branded T-shirts from the same workstation.
It is important to note a specific design choice: during the initial setup, you must determine whether the second printhead will function for UV or DTF printing.
Once the ink system is configured, I don’t recommend changing it, ensuring the lines remain clean and the output stays professional for the life of the machine.
Longer ePrint Material Compatibility: Print on 300+ Surfaces
The ePrint is compatible with over 300 different materials, but its true strength lies in how it handles difficult surfaces.
Standard UV printers require a perfectly flat surface to maintain focus and prevent ink misting. The Longer ePrint uses 10mm high-gap printing technology.
This allows the printhead to stay safely above the material while maintaining a precise and stable ink ejection.
This feature opens up a range of “real-world” objects that were previously difficult to customize:
- Irregular Surfaces: Flawless prints on rough stone, embossed wood, and even wrinkled leather bags.
- Curved Objects: Using specialized modes like rotary and conveyor, you can print directly on stainless steel bottles, glass cups, and thermos mugs.
- Double-Sided Effects: The software allows for precise layering on clear acrylic, creating a matte finish on one side and a glossy finish on the other for high-end signage or keychains.
To support this variety, the printer features an open ink system. While Longer provides its own high-quality inks, the machine is compatible with third-party soft inks, hard inks, fluorescent options, and even food-safe inks for printing on tableware and food packaging.
The system also features twelve 200ml ink cartridges, ensuring you can run large batches without constant refills.
3D Texture Printing and Tactile Branding with Longer ePrint
A standout feature of the Longer ePrint is its 1440 DPI resolution and the ability to reproduce over one million colors with stunning accuracy.
This high resolution is critical when building 3D textures, as it ensures that each stacked layer is smooth, perfectly aligned, and free of rough edges.
Creators can use this to produce:
- Embossed Braille Signage: Making accessibility signage easier to produce in-house.
- Relief Sculptures: Turning a flat image of a lion or a floral pattern into a tactile piece of art where the shadows and lighting are physically represented by ink depth.
- Tactile Branding: Adding a premium feel to business cards or product packaging that customers can feel with their fingers.
Longer ePrint AI Tools for Faster Design and Batch Alignment
Longer has integrated eight specific AI tools into their dedicated software to remove the technical barriers often associated with professional printing.
These tools are designed to handle the labor-intensive parts of the workflow:
- Flat-to-3D Modeling: This tool automatically analyzes an image’s color to calculate depth, generating a raised 3D surface without requiring the user to manually create complex layer maps in Photoshop.
- Text-to-Image Generation: Users can type a simple description, such as “roses in a hand-painted style”. and the AI generates a professional print template in seconds.
- Auto-Positioning and Batch Alignment: This is perhaps the most practical efficiency tool. A built-in camera takes a snapshot of the print bed. You can drop multiple items (like a phone case and an earbud case) randomly on the platform, and the software will automatically detect their positions and align the logos for a perfect print in one click.
Longer ePrint Brand Background and Kickstarter Credibility
Longer is not a newcomer to the industry. Founded in 2016 by Dr. Lao and Dr. He, the company is built on a foundation of Ivy League-trained engineers and the technological legacy of RepRapPro, a British pioneer in 3D printing.
Over the last decade, they have developed more than 120 professional devices and successfully completed four Kickstarter campaigns, earning the trust of over 2,400 backers.
Final Verdict: Is Longer ePrint Worth Backing?
The Longer ePrint represents a shift away from “hobbyist” tools toward “production” tools that fit on a desk.
By doubling the printheads and automating the design process with AI, it removes the speed and complexity barriers that have kept many creators from adopting UV printing.
Whether you are looking to revitalize old items(like a leather bag), or launch a small-batch customization business, the Longer ePrint provides the technical precision and material versatility to make it possible.
