Mingda AD-F4 – specialized 3D printer for channel letters and professional signage

Mingda AD-F4 is an industrial FDM 3D printer designed from the ground up for the production of channel (illuminated) letters, logos, and large-format advertising elements. It combines a large print volume of 800 × 1200 × 100 mm, the IMS automatic four-color system, high-speed printing with Klipper firmware, and advanced automation features.

This makes the AD-F4 ideal for advertising agencies, signmaking studios, illuminated sign manufacturers, architectural signage, and POS/POP displays, where speed, color, and consistent quality are key.

Key Features

• Giant print volume 800 × 1200 × 100 mm Print entire channel letters or lightbox parts in one piece, without the need for gluing and joining.
• IMS four-color automatic feeding system One hotend with 4 separate filament inputs (4-in-1), automatic color change during printing. Allows for:
  • multi-color letters and logos in a single print,
  • sharp transitions and smooth color gradients,
  • minimization of color contamination thanks to optimized feeding.
• High-speed printing with Klipper
  • maximum print speed up to 350 mm/s (material dependent),
  • recommended working speed up to approx. 200 mm/s for signage,
  • acceleration up to 10,000 mm/s² for quickly reaching working speed,
  • input shaping to suppress vibrations and improve surface quality even at high speeds.
• Air-heated print bed with glass plate
  • air heating with max. bed temperature around 60 °C,
  • tempered glass for a flat surface and easy removal of parts,
  • reduced warping for large flat parts (front panels of letters, logos, signs).
• Automation and reliability for serial production
  • 3. rd generation automatic leveling (auto-leveling)
    – fast and precise preparation,
  • filament sensor and power loss recovery,
  • industrial construction with a stable frame for long print times,
  • safety features: three-color warning light, emergency stop button, circuit breaker.
• Remote control and monitoring
  • 7" touchscreen for convenient control directly on the machine,
  • Wi-Fi connection and USB (U-disk) for data import,
  • integrated camera for remote print surveillance (Klipper web interface).
• Software support for channel letters
  • proprietary software AdWordCraft and MINGDA Slicer designed for signmaking,
  • support for formats DXF, SVG, STL, STP, 3MF, AMF, OBJ,
  • easy import of vector graphics, texts, and logos, generating 3D channel letters from fonts.

Typical Applications

• LED channel (illuminated) letters
  • 3D prints of letter bodies with integrated space for LEDs,
  • various wall and front cover colors in one print,
  • indoor and outdoor advertising signs.
• Lightboxes and backlit panels
  • front panels and frames for lightboxes,
  • menu boards in gastro operations, information panels.
• 3D logos, brands, and decorative elements
  • spatial logos for showrooms and receptions,
  • imaginative 3D signs, numbers, and pictograms,
  • architectural elements and decors.
• Serial and custom production
  • efficient production of multiple letters or sets of logos in one job,
  • suitable for non-stop operation and industrial environments.

Supported Materials

Mingda AD-F4 is optimized for materials used in advertising and illuminated signs:

• PLA – easy to print, suitable for interior advertising.
• PETG – more durable and partially flexible material, suitable for outdoor installations.
• PDS and other special signage filaments – materials developed for semi-translucent and backlit applications, suitable for LED letters and lightboxes.

The open filament system allows for the use of other compatible materials with a diameter of 1,75 mm within the recommended temperatures.

Technical Specifications

Why choose Mingda AD-F4 for your signage production

• Significant reduction in project costs – in-house letter production instead of purchasing finished parts.
• Faster delivery times – overnight printing, minimum manual labor, no waiting for external suppliers.
• More creativity in design – freer shapes, 3D effects, color combinations, and textures that classic technologies cannot achieve.
• Scalability – the ability to operate multiple machines in parallel, centrally manage jobs, and monitor printing remotely.

Mingda AD-F4 is a powerful tool for anyone who wants to take the production of channel letters and advertising signs to the next level while maintaining full control over quality, deadlines, and costs.
