Unlimited Production of 3D Signs and Channel Letters

With a print volume of 1200 × 800 × 100 mm, the Mingda AD-F4 enables the production of large-scale channel letters and full 3D signs without compromising on quality or detail. Thanks to its advanced FDM technology and Klipper firmware, the printer reaches speeds of 200-300 mm/s, drastically reducing production times and multiplying the capacity for custom signage and LED letters.

Automatic 4-Color System

The exclusive four-extruder system allows printing multicolor channel letters, gradients, and branded designs in a single process, something no conventional printer can achieve. This ensures that every 3D sign and channel letter is produced with high-impact finishes and professional-quality results.

For a complete professional production workflow, the Mingda AD-F4 works in tandem with the MD-C02 UV curing machine, specially designed to handle printed parts. After 3D printing signs, channel letters, and LED signage, the MD-C02 provides fast, uniform curing, ensuring smooth surfaces, dimensional stability, and installation-ready finishes. This creates an advanced manufacturing solution that optimizes time, reduces rework, and elevates product quality.

Remote Monitoring and Smart Connectivity

Thanks to built-in Wi-Fi and camera, the AD-F4 allows remote monitoring and control of prints, optimizing the production of 3D signs and channel letters even in workshops handling multiple projects simultaneously.

Key Benefits for Signage Workshops and Manufacturers

• Save time and costs on every channel letter and 3D sign project
• Continuous multicolor production without manual intervention
• High precision and professional finishes with minimal warping
• Compatible with industrial and commercial LED signage production
