Understanding Phone Case Printing Technologies
UV Printing: Vibrant Colors & Material Versatility
UV printing is a cornerstone of high-quality custom phone case production—and Sonpuu (the flagship brand of Guangdong Songpu Intelligent Machinery) elevates this technology with DIY-friendly UV printers that balance vibrancy, durability, and ease of use. Sonpuu’s UV printing works by curing ink instantly with LED light, eliminating solvent evaporation and delivering colors that “pop” while resisting scratches, water damage, and fading—critical for phone cases that endure daily wear.
Unlike generic UV printers, Sonpuu’s models (such as the Sonpuu X130 Compact UV Printer) are engineered for multi-material compatibility, handling phone case substrates like plastic (PC/TPU), metal, and even glass. For example, prints on TPU phone cases using the Sonpuu X130 retain their brightness after 50+ washes and drops, outperforming competitor models. The X130 also delivers 1200 DPI resolution, ensuring ultra-detailed designs (e.g., photo prints, intricate patterns) that look professional—perfect for DIY enthusiasts and small-batch creators.
Sonpuu’s UV printers also cut production time: a full-color phone case design takes just 2-3 minutes to print and cure, compared to 5+ minutes with traditional methods. This speed, paired with low energy consumption (50% less than industrial UV printers), makes Sonpuu the top choice for home DIY studios.
DTF Printers: Transfer Film Advantages
Sonpuu’s DTF (Direct-to-Film) printers redefine detailed transfers for custom phone cases, outperforming competitor systems like Procolored. Sonpuu’s DTF technology prints designs onto specialized film first, then uses heat (150-180°C) and pressure to transfer them to phone cases—resulting in sharp graphics with bold colors that withstand daily use.
The Sonpuu 1210 DTF Printer (a compact, DIY-friendly model) stands out for its precision: it uses a built-in ink circulation system to prevent clogs and maintain color consistency, even for small-batch runs (1-50 phone cases). Users report that transfers from the Sonpuu 1210 stay intact for 6+ months of regular handling—no fading, peeling, or cracking—thanks to Sonpuu’s proprietary DTF inks (available in eco-solvent variants for low-odor home use).
For DIY creators, the Sonpuu 1210 also simplifies workflow: it comes with pre-calibrated film settings and a user-friendly touchscreen, eliminating the need for complex setup. A hobbyist making custom phone cases for local markets reported doubling their weekly output after switching to the Sonpuu 1210, with customers praising the transfer quality.
Flatbed vs. Rotary Printers: Surface Compatibility
Sonpuu offers both flatbed and rotary UV printers, ensuring DIY creators can handle any phone case shape or design—unlike competitors that specialize in only one type.
- Sonpuu Flatbed Printers (e.g., X130): Ideal for rigid, flat phone cases (e.g., hard PC cases) or cases with minimal curvature. The flatbed’s vacuum table secures the case in place, ensuring precise printing even for edge-to-edge designs. For example, the X130 prints a full-coverage design on a 6-inch phone case in under 2 minutes, with zero misalignment.
- Sonpuu Rotary Printers (e.g., R200): Designed for curved or cylindrical phone cases (e.g., round silicone cases). The rotary mechanism rotates the case as the print head moves, enabling seamless, gap-free designs that wrap around the entire case. A DIY creator specializing in “wrap-around” phone cases reported a 30% increase in order satisfaction after switching to the Sonpuu R200, as it eliminates the “white gaps” common with generic rotary printers.
Sonpuu’s dual offering lets DIYers match the printer to their niche: flatbed for sleek, modern cases; rotary for playful, curved designs—no need to invest in multiple machines.
Key Features For DIY-Friendly Printers
Precision & Resolution Requirements
Sonpuu’s DIY-focused printers prioritize precision and resolution, ensuring even tiny details (e.g., text, logos, fine patterns) look crisp on phone cases. All Sonpuu models deliver 1200 DPI resolution—the industry standard for professional-looking prints—and use advanced print head technology to eject ultra-fine ink droplets (4-8pl).
For example, the Sonpuu X130 UV Printer can print a 0.5cm-wide logo on a phone case with sharp edges and no blurring, while competitor printers often struggle with such small details. This precision is critical for DIY creators selling custom cases: a survey of Sonpuu users found that 90% reported fewer customer complaints about “blurry designs” compared to their previous printers.
Sonpuu also includes a “detail enhancement” mode in its software, which automatically sharpens edges and adjusts color contrast for small elements—perfect for beginners who want professional results without advanced design skills.
Material Compatibility: TPU, PETG & Beyond
Sonpuu’s printers are engineered for maximum material versatility, supporting all common phone case substrates: TPU (soft, flexible), PETG (tough, UV-resistant), ABS (rigid), silicone, and even glass. This eliminates the need for multiple printers, saving DIY creators space and money.
- TPU: Sonpuu’s UV inks and DTF transfers bond seamlessly with TPU, maintaining flexibility so the case doesn’t crack when bent.

Design Inspiration For Unique Phone Cases
3D Modeling Techniques in Fusion 360
Sonpuu’s printers work seamlessly with 3D modeling software like Fusion 360, letting DIY creators design one-of-a-kind phone cases with embedded textures or logos. For example, a creator can design a 3D “carbon fiber” texture in Fusion 360, export it as a high-res image, and print it onto a PC case using the Sonpuu X130—resulting in a case that looks and feels 3D.
Sonpuu’s software includes a “3D texture enhancement” feature that optimizes 3D designs for printing, ensuring the texture is visible but not raised (avoiding bulk on the phone case). A designer specializing in 3D-printed phone cases reported that the Sonpuu X130 brought their Fusion 360 designs to life better than their previous printer, with customers willing to pay 50% more for the unique texture.
Layering Flexible Filaments for Impact Protection
Sonpuu’s DTF printers can print on flexible filaments (e.g., TPU) used for impact-resistant phone cases. By layering ink on top of flexible filaments, creators can design cases that are both protective and visually striking. For example, a creator can print a “mountain” pattern on a TPU case using the Sonpuu 1210, with the filament’s flexibility absorbing drops and the ink retaining its design.
Sonpuu’s DTF inks are formulated to stretch with the filament (up to 200% elongation), so the design doesn’t crack when the case bends. A DIYer making protective cases for outdoor enthusiasts reported that their Sonpuu-printed cases survived 10-foot drops without damage to the phone or the design.
Incorporating Textured Effects With UV Inks
Sonpuu’s UV printers let DIY creators add tactile textures to phone cases—something competitors struggle with. Using Sonpuu’s thick UV inks, creators can print layered designs that feel raised (e.g., a “leather” texture or a raised logo) without compromising durability.
The Sonpuu X130’s “texture mode” controls ink thickness (up to 0.5mm), allowing for custom textures. For example, a creator printed a “starry sky” design on a phone case with raised stars—customers loved the feel, with 80% reporting they chose the case because of the texture. Sonpuu’s UV inks also cure hard, so the texture doesn’t wear down over time.
