Resin Tray Guidelines
The membrane contained within each resin tray is the most fragile component of the Figure 4 Standalone Printer. It must be handled with care. Follow all resin-tray guidelines and procedures to avoid membrane damage and failure.
HARMFUL IRRITANT WARNING: Wear protective clothing, disposable nitrile gloves, and goggles while handling the resin tray.
CAUTION: If a leak/spill occurs, do not run the machine. UV curing will harden the resin on unwanted surfaces and will make the resin very hard to remove. A nonabrasive cloth and IPA will help clean up any spilled uncured resin.
CAUTION: Failure to clean the resin tray of partially cured resin will lead to membrane failure and failed prints.
- Expected lifetime of the resin tray is around 900 builds.
- Do not apply pressure to the membrane. Deformations form easily and permanently, and may lead to membrane failure and degradation of print quality. Never touch the membrane with sharp objects.
- Do not touch the membrane with bare skin. Skin oils may cause print-quality degradation.
- Always verify that all printed parts and supports have been accounted for after a build. Be sure to inspect the resin tray for partially cured material. Cured material (also called green material) that is clear, or tiny bits of cured material may not be visible to the naked eye. If you suspect that partially cured material might be present in the tray, you must clean the tray before building again.
- Always ensure there is enough print material in the resin tray to complete a build before starting the print job. Adding additional material during a print job is not recommended, as it would require opening the printer lid during printing.
- With thorough cleaning of the resin tray in between builds, it is possible to use different resins in the same resin tray (not at the same time). Please see the section Resin Tray Resin Cross-Usage for information on which resins may share a single resin tray. Do not mix two or more types of resin in the resin tray. Doing so will cause both materials to become ineffective.
- Avoid transporting a resin tray that is filled with resin so as to avoid spills. Always carry resin tray with both hands to help ensure that it does not drop on the floor. Any damage to the resin tray would mean that the resin tray needs to be replaced.
- Do not move the printer while there is a resin tray inside that is filled with resin. Even moving the printer a few inches with resin inside can cause a resin spill.
- Uncovered resin trays should not be left outside the Figure 4 Standalone Printer when containing any amount of print material. Material will cure when exposed to ambient light. Cured material is extremely difficult to remove from the resin-tray membrane without causing damage. If you store a resin tray containing material outside the printer, use the resin-tray garage and store the tray in a cool, dark place.
- Resin overflow from the resin tray will be channeled into the catch tray. Discard the resin in the catch tray according to all government regulations.
- When pouring print material back into its bottle, be sure to use a filter, as seen in the section Clean Resin Tray.
- Always ensure the resin tray is clean of uncured liquid resin and partially cured bits before each print.
- Always ensure that the resin tray is not damaged in any way, particularly on the membrane. Resin-tray damage could cause build failure and/or resin leakage. Resin-tray damage can be: membrane puncture, dent, scratch or discoloration.
