xTool OR1 Rotary Attachment for O1 Omni Printer

The xTool OR1 Rotary Attachment for O1 Omni Printer expands the O1 Omni’s direct UV printing capabilities from flat objects to a wide range of curved products. Designed exclusively for the xTool O1 Omni Printer, the OR1 supports popular cups, cans, ornaments, small spheres, candle jars, open glassware, and other securely clampable curved workpieces.

With its adjustable jaw chuck, tail module, angle-controlled 360° rotation, and Pixel-Scan™ vision system, the xTool OR1 Rotary Attachment for O1 Omni Printer is designed to make curved printing more precise and easier to set up. It can also extend O1 Omni printing effects to curved objects, including texture, raised relief, and fluorescent effects.

Key Features

Direct UV Printing on Curved Objects

The xTool OR1 Rotary Attachment for O1 Omni Printer allows the O1 Omni to print directly onto compatible curved surfaces. The rotary attachment supports a variety of everyday objects, including mugs, tumblers, straight cylindrical cups, tapered vessels, beverage cans, spherical ornaments, candle jars, and open glassware.

The OR1 is specifically designed for the O1 Omni Printer and is not compatible with other xTool printers.

Seamless 360° Full-Wrap Printing

The xTool OR1 Rotary Attachment uses a jaw chuck and angle-controlled 360° rotation to create full-wrap prints around compatible curved objects.

Unlike roller-based rotary systems that may require manual circumference measurements, the OR1 is designed to hold the workpiece securely and rotate it precisely. This helps reduce gaps, overlaps, and seam misalignment during full-wrap printing.

Pixel-Scan™ Vision System

The OR1 features xTool’s Pixel-Scan™ and CIS Imaging technology. The system can capture the object’s shape and surface details, detect handles, and help create a 1:1 preview for accurate design placement.

The software workflow also allows users to preview the workpiece in 3D before printing, helping verify the design position before processing.

Smart Handle Detection

When printing on handled cups, the xTool OR1 Rotary Attachment for O1 Omni Printer can identify handles, measure their height, and mark no-print areas.

This helps reduce the risk of printing into restricted areas and supports safer positioning around cup handles.

Automatic Leveling for Tapered Objects

The OR1 supports automatic leveling across a taper range of -8° to 12°. This allows compatible tapered cups and vessels to be aligned into a stable printing plane.

For cylindrical or tapered cups, xTool specifies that the printable area should stay within a 0.04-inch height difference for best results.

Adjustable Jaw Chuck

The xTool OR1 Rotary Attachment uses an adjustable jaw chuck designed to securely hold compatible open containers and cups.

The chuck supports cup openings with an inner diameter of 1.83 to 3.94 inches, while supported cup and container dimensions depend on the specific workpiece shape.

The jaws and tail module provide support at both ends for smoother and more consistent rotation.

Supported Workpieces

The xTool OR1 Rotary Attachment for O1 Omni Printer supports a variety of securely clampable and rotatable objects.

Compatible workpiece categories include:

• Mugs
• Tumblers
• Straight cylindrical cups
• Tapered vessels
• Beverage cans
• Spherical ornaments
• Candle jars
• Open glassware
• Select irregular drinkware
• Other compatible open-top containers

The workpiece must be capable of being securely clamped and rotated without wobbling, and the target print area must avoid rims, inner linings, handle joints, and food-contact surfaces.

Supported Workpiece Specifications

These specifications are from the official xTool product information.

Advanced Printing Effects

The xTool OR1 Rotary Attachment for O1 Omni Printer extends several O1 Omni printing effects to curved surfaces.

Texture Printing

Create multi-layer surface texture up to 0.2 inches for designs that can be seen and felt.

Raised Relief

The OR1 supports raised relief effects up to 0.2 inches, allowing names, logos, artwork, and other details to stand out from the curved surface.

Fluorescent Effects

Fluorescent effects can also be applied to compatible curved workpieces. xTool specifies that fluorescent ink printing is supported when the OR1 is paired with the dual UV version of the O1 Omni Printer.

Fast and Secure Installation

The xTool OR1 Rotary Attachment uses a magnetic connection to attach securely to the O1 Omni Printer’s extension base.

The official support guide explains that the printer’s extension base automatically ejects when the O1 Omni is activated, after which the OR1 main unit can be installed onto the base.

Easy Rotary Printing Workflow

Using the xTool OR1 Rotary Attachment for O1 Omni Printer involves calibration, workpiece installation, modeling, design placement, previewing, and printing through xTool Studio.

The official workflow includes:

1. Select Rotary mode in xTool Studio.
2. Start rotary attachment calibration.
3. Install the OR1 main unit.
4. Complete axis calibration.
5. Install and secure the workpiece.
6. Model the workpiece in the software.
7. Import and position the design.
8. Preview the 3D print placement.
9. Adjust Flat, Texture, or Relief settings as needed.
10. Process and print.

The 3D preview and full-wrap layout tools can help users check placement before beginning the final print.

Surface Preparation

Proper surface preparation is important when using the xTool OR1 Rotary Attachment for direct UV printing.

For glass or ceramic objects, xTool recommends cleaning the surface with the included cleaning wipe to remove dust and oil. After the surface dries naturally, a primer wipe can be applied to the print area to improve ink adhesion.

For stainless steel objects, xTool recommends using a dedicated primer wipe to improve ink adhesion.

Important Printing Limitations

The xTool OR1 Rotary Attachment for O1 Omni Printer is designed for securely clampable and rotatable objects. Objects that cannot be held or rotated stably are not recommended.

Examples include rolling pins, solid candles, complex multi-handle cups, or objects where the rim, base, or connection structure interferes with the intended print area.

UV ink should not come into direct contact with lips, drinks, food, or food-contact areas. Printing should be limited to suitable exterior, non-contact surfaces.
