To better meet the flexible production needs of small and medium-sized jewelry workshops, the WJ51C was designed with two distinct printing modes: single-channel and dual-channel. Each mode is built for a different type of workflow—whether you need fast prototyping or stable small-batch production.

In practical production scenarios, some orders require quick turnaround for design validation, while others focus on maximizing output over time. By balancing speed and productivity, the WJ51C allows users to choose the most efficient production method based on actual business needs.

1. Key Differences Between Single-Channel and Dual-Channel Printing

The WJ51C features a build volume of 235 × 138 × 100 mm. Within this space, the printer operates differently depending on how the printhead moves along the Y-axis.

Single-Channel Mode

In single-channel mode, the printhead operates within a fixed area without moving along the Y-axis. The printing path is simpler and more direct, allowing faster layer progression. This makes it ideal for time-sensitive tasks such as rapid prototyping.

Printing speed: ~7 mm/hour

Dual-Channel Mode

In dual-channel mode, the printhead moves across the Y-axis, utilizing the full build platform. Although this introduces more movement and slightly reduces speed, it allows multiple models to be printed simultaneously, increasing overall productivity.

Printing speed: ~3.2 mm/hour

2. Why Is Dual-Channel Slower but More Productive?

The advantage of dual-channel printing is not speed, but efficiency and platform utilization.

By working across a larger area, the printer can place more models in a single job and maximize the use of available space. This allows for higher-density production even though each layer takes longer to complete.

In addition, the WJ51C supports a build height of up to 100 mm, enabling:

• Multi-layer stacked production
• Overnight unattended printing (with sufficient material loaded)
• Higher output per production cycle

With this approach, the WJ51C can achieve a monthly output of 3–4 kg, approaching the capacity of larger industrial systems.

3. When Should You Use Each Mode?

Choosing the right mode depends on your current production stage and order type.

Use Single-Channel Mode When:

• Validating design concepts
• Creating quick prototypes for clients
• Adjusting ring size, thickness, or structure
• Producing display samples

Use Dual-Channel Mode When:

• Producing multiple pieces in one batch
• Handling multiple designs simultaneously
• Maximizing machine utilization
• Running overnight or continuous production

Conclusion

By offering both single-channel and dual-channel printing modes, the WJ51C provides a flexible balance between speed and productivity. Whether you are working on rapid design validation or small-batch production, you can adjust your workflow to match your business needs—without switching machines.
