Hoopat Quick Release Resin Vat Upgraded Version with Seal Ring

A: The pogo pin on the X4H resin vat has been upgraded with enhanced spring force and extended service life. Its exposed length is shortened to reduce contamination risks, ensuring reliable printing on your ELEGOO Saturn 4 Ultra.

A: Yes, the new release film with the sealing ring is fully compatible with older Hoopat resin vats.

A: No, the old release film without sealing ring is NOT recommended for use with the new Hoopat.

A: Yes — the Hoopat quick release resin vat works with any third-party release film (FEP, PFA/nFEP, or ACF). However, you'll need to punch the alignment holes yourself for a proper fit. For the best experience, we recommend our Hoopat Pre-Cut Films, available in high-quality FEP, ACF, and PFA (nFEP) options at a fair price — pre-cut and ready to install in seconds.

A: If your first print fails after installing the Hoopat vat, try these steps: First, re-level your building plate to ensure proper alignment with the new vat. Then, slightly increase the bottom exposure time in your resin print settings.

A: Resin leakage is usually caused by one of these installation issues: 1) Make sure to remove both protective films from the PFA sheet (one on each side) before installation — leaving them on prevents proper sealing. 2) Secure clips using both hands simultaneously — clipping one at a time creates uneven tension and gaps. 3) Avoid repeatedly clipping and unclipping the same film, as this stretches the alignment holes and causes irreversible deformation that prevents a tight seal.

A: If your print fails with ACF film, check whether the film is installed upside down. The matte (frosted) side of the ACF film must face downward toward the LCD screen. Installing it the wrong way increases peel force dramatically, leading to print failure and potential film deformation. Always verify: matte side down.

A: The Hoopat X4H resin vat includes a heating function for the ELEGOO Saturn 4 Ultra. During installation, the bottom probe must be aligned with the heating element located on the right side of the LCD screen.
