A3 UV Printer R1390 UV Flatbed with Rotary Axis - Compact A3 UV

Our review of the A3 UV Printer R1390 finds it best suited for small shops and makers who need a versatile, compact UV flatbed that can handle both flat and cylindrical objects. The biggest reason to buy is its simultaneous white and color printing with a dedicated white ink circulation system, which prevents nozzle clogging and keeps multi-layer prints consistent. For anyone printing phone cases, wood panels, or promotional bottles, this unit offers a practical A3 working area and rotary axis without an ink supply included, making it a tool-oriented purchase for users ready to source inks separately.

Key Features

• R1390 Printhead: Supports bidirectional printing and simultaneous white and color output for faster, full-color jobs with white underprint when required.
• White ink circulation: Automatic circulation moves white ink into an ink sac to prevent precipitation and reduce nozzle blockages during long runs.
• A3 working area: A platform size of 297 by 420mm with an effective UV print area of 267 by 420mm fits small signs, phone shells, and sample prints without wasted space.
• Flatbed and rotary capability: Includes a rotary axis and A3 T-shirt fixture so the machine can print on cylinders like bottles and cups as well as flat substrates.
• Wide substrate compatibility: Accepts plastics, acrylic, wood, leather, metal, ceramic tile and more, enabling diverse product runs from phone cases to golf balls and stone reliefs.
• Support and warranty: Two years machine warranty with remote assistance, manuals and operation video help reduce setup time and troubleshooting.

Who It's For

This printer is aimed at small production shops, custom goods makers and prototypers who need a compact UV printer capable of handling varied materials like PVC, acrylic, wood, leather and metal. It is especially useful for creators who need white-ink printing for opaque or layered designs and who will benefit from the included rotary axis for bottles and mugs.

Users who want a turnkey ink-inclusive solution should look elsewhere, since the package lists the machine and fixtures with 500ml UV hard inks but is sold without ongoing ink supply included; hobbyists unwilling to manage ink sourcing or those needing larger than A3 throughput should consider larger flatbeds or service providers.

Pros & Cons

Pros

• Simultaneous white and color printing reduces steps for multi-layer jobs and speeds production.
• White ink automatic circulation helps prevent nozzle clogging and maintains print reliability.
• Included rotary axis and T-shirt fixture broaden the range of printable items from flat boards to bottles.
• Compact A3 footprint fits small workspaces while supporting a useful effective print area.

Cons

• Sold without ongoing ink supply; buyers must plan ink sourcing and maintenance materials themselves.
