Replacing the release film on a traditional resin vat can be time-consuming. Multiple screws, film positioning, tension adjustments, and trimming all add steps to a task you may need to repeat regularly. The Chitu Systems Hoopat quick-release resin vat is designed to make resin vat film replacement simpler. Its screw-free clamping frame works with pre-cut, pre-punched PFA or ACF films, so you can spend less time on maintenance and more time printing. 01 | Snap. Seal. Done: A Faster Way to Replace Resin Vat Film Inspired by the straightforward action of a snap-on lid, Hoopat replaces the usual screw-by-screw film installation process with a quick-release frame. Screw-free film changes: The quick-release mechanism is designed for film replacement in around 30 seconds once you are familiar with the process. More consistent film tension: The frame applies even pressure around the film, reducing the need for manual tension adjustments. No manual trimming with compatible Hoopat films: Hoopat's pre-cut, pre-punched release films are sized for the corresponding vat. Choice of PFA or ACF: Select the release film type that suits your printer and printing settings. The result is a more repeatable maintenance process. The film still needs to be installed correctly, inspected for damage, and checked for leaks before printing. 02 | Built for Everyday Resin Printing The quick-release mechanism is only part of the design. Hoopat also includes practical features for handling resin and maintaining the vat: Full-metal construction: A durable metal frame replaces the earlier plastic approach and is designed for repeated use. Integrated pouring spout: Helps return resin to its container with greater control and less mess. Capacity markings: Make it easier to monitor the resin level when filling the vat. Consistent clamping: Helps keep the release film seated evenly across the frame. 03 | Updated Features: Seal Ring and X4H Heating Compatibility Hoopat has continued to evolve based on practical installation and printing needs. An Optional Seal Ring for Improved Sealing The newer seal-ring configuration adds a silicone gasket to help improve sealing around the release film. The correct seal-ring and film combination depends on which package you choose: Standard: No seal ring included. Best Value: Seal ring included in the film pack. Upgraded: Seal ring included in the vat pack. Hoopat also offers replacement PFA/ACF films, with or without seal rings . Select the film size and configuration that matches your Hoopat model. X4H Supports the Saturn 4 Ultra 16K Heating System The Hoopat X4H is designed for the ELEGOO Saturn 4 Ultra 16K and supports the printer's resin-heating function through the appropriate heating contacts. X4H does not contain a separate, independent built-in heater. Correct installation and clean contact points are important for heating detection and operation. The X4H design also incorporates spring-loaded contact components intended to improve connection reliability. If the printer does not detect the vat, check that it is seated correctly and that the contact area is clean. 04 | Hoopat Model Compatibility Guide Hoopat is available in several versions for selected ELEGOO Saturn and Anycubic Photon Mono resin 3D printers.

Compatible third-party film sheets may be used, but standard sheets are usually not pre-punched. They may require additional preparation to fit Hoopat's locating points. Hoopat's own pre-cut, pre-punched films provide the most convenient installation process. Should I choose PFA or ACF release film? PFA is a common general-purpose option, while ACF may be suitable for specific high-speed printing setups. Check the film originally specified for your printer and be prepared to adjust exposure and other print settings if you change film type. Can I use seal-ring release films with an older Hoopat vat? The newer Hoopat seal-ring film configuration is compatible with older matching Hoopat vats. Always choose the correct model-specific film and follow the current installation instructions. What should I check if my Hoopat vat leaks after a film change? Check for punctures or damaged film edges, remove all protective layers, make sure the film and optional seal ring lie flat, clean away cured resin around the sealing surface, and engage all clips evenly. Perform a leak check before reinstalling the vat on the printer. Where can I find the Hoopat installation instructions? Follow the official Hoopat installation guide for step-by-step film and seal-ring installation instructions.
