Mingda - AD-F4-Mini 3D Printer

The Mingda AD-F4 Mini is a high-performance industrial FFF 3D printer, developed for the rapid and efficient production of channel letters, signs, logos, and other profiled products. With a generous build volume of 800 × 600 × 100 mm , an integrated 4-color material system, and Klipper firmware, you can go from design to finished product, whether it's a sign or a profile, faster, with less manual work, and higher productivity. The result is shorter lead times, lower production costs, and increased capacity for professional sign production.

Highlights

• Large build volume of 800 × 600 × 100 mm
• IMS system (4-in / 1-out) for automatic multi-color printing.
• Klipper firmware for fast and stable performance.
• Print speeds up to 300 mm/s (0.4 mm nozzle) or up to 150 mm/s with the standard 0.6 mm nozzle.
• Nozzle temperature up to 300 °C and heated bed up to 80 °C
• Automatic bed leveling, filament monitoring, and power outage recovery.
• 2D vectors can be converted directly into print-ready 3D models.
• Wi-Fi, Ethernet, and USB connectivity.
• Integrated emergency stop button and status warning light for safe operation.

Developed for professional sign production.

The AD-F4 Mini is designed for sign makers, advertising agencies, and companies that produce channel letters, LED signs, and other profiled products. Thanks to the large print volume, numerous signs and letters can be printed in one piece instead of several smaller sections. This reduces assembly time, ensures a cleaner final result, and helps reduce labor costs and increase production capacity.

From 2D design to finished sign in less time

The included SignMaker software and MINGDA Slicer allow you to import standard vector files such as .SVG and .DXF to quickly create print-ready 3D models. This minimizes the need for manual CAD work and allows existing logos and designs to be quickly converted into print-ready models. The result is a more efficient workflow, from the customer's graphic to the finished product.

Automatic multi-color printing without manual intervention

The integrated IMS 4-in-1-out system handles up to four filament spools simultaneously and automatically switches materials during the printing process. This allows you to create multi-color logos, letters, and signs without manually changing the filament, saving time, reducing production interruptions, and optimizing the workflow. Foldable spool holders also help make the workstation more compact and easy to maintain.

High productivity with Klipper

Klipper firmware, combined with XY movement speeds up to 500 mm/s, makes the AD-F4 Mini optimized for rapid batch production. With a 0.4 mm nozzle, print speeds of up to 300 mm/s can be achieved, while the standard 0.6 mm nozzle ensures high material flow for large signs and letters. This results in more finished products per day, shorter lead times, and makes the printer particularly suitable for companies with high or recurring production volumes.

Designed for stable and safe operation.

Automatic bed leveling, filament detection, and power outage recovery minimize the risk of print errors and material waste. The physical emergency stop button and status warning light help ensure a safe working environment even during extended production cycles.

Flexible material handling

The AD-F4 Mini supports 1.75 mm filaments such as PLA, PETG, AdPETG Tough, and PDS. The nozzle reaches temperatures of up to 300 °C and the heated glass print bed up to 80 °C , offering compatibility with various materials commonly used in sign and profile production. The standard equipment includes a 0.6 mm nozzle, while 0.4 mm and 0.8 mm nozzles are available as options to optimize details or print times.

Optimize the entire production workflow.

Thanks to the combination of a large build volume, high print speeds, automated multi-color printing, and intelligent 2D to 3D conversion software, the AD-F4 Mini offers a complete production solution for modern sign making. From the initial design file to the finished product, it reduces manual work steps while increasing production capacity and maintaining consistently high print quality.
