Introduction
If you own an Asiga 3D printer and are using either a LowForce or an UltraGloss tray, you may have noticed a small hole near the bottom of the tray film. This feature might initially seem unusual or even a cause for worry, but it is an intentional part of the tray’s design.

Purpose of the Hole
The hole is designed to prevent air from becoming trapped between the layers of the tray film. During the printing process, negative pressure can build up between the resin and the film, potentially causing suction or vacuum-related issues. The small opening allows air to equalize, preventing such pressure buildup and ensuring smooth resin flow across the print area.

No Cause for Concern
Although it may look like a potential leak point, the hole does not cause resin to spill. The film and surrounding tray structure are engineered so that resin remains contained within the printing area. This pressure-release design keeps both the resin and the printer mechanism safe, maintaining consistent printing quality without causing damage or mess.

Conclusion
The small hole at the bottom of Asiga LowForce and UltraGloss trays is an intentional feature that helps equalize pressure and prevents vacuum-related issues during printing. It is not a defect and does not lead to resin spills. You can continue using these trays with confidence, knowing that the design is working as intended to support reliable and high-quality prints.
