Resin Tray Guidelines

The membrane on each Resin Tray is the most fragile component of the Figure 4 Modular system. 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 light will harden the material on unwanted surfaces and will make the material very hard to remove. A nonabrasive cloth and IPA will help clean up any spilled uncured material.

CAUTION: Failure to clean the Resin Tray of partially cured material may lead to membrane failure and failed prints.


  1. With proper care and handling, the expected lifetime of a Resin Tray is approximately 900 builds.
  2. 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.
  3. Do not touch the membrane with bare skin. Skin oils may cause print-quality degradation. If contaminated, clean membrane with IPA and lint-free cloth
  4. 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 run a resin-tray cleaning before printing again.
  5. With thorough cleaning of the Resin Tray in between builds, it is possible to use different materials in the same Resin Tray (not at the same time). Please see the section Resin Tray Material Cross-Usage for information on which materials may share a single Resin Tray. Do not mix two or more types of material in the Resin Tray. Doing so will cause both materials to become ineffective.
  6. Take care when transporting a Resin Tray that is filled with material, so as to avoid spills. Always carry Resin Tray with both hands to help ensure that it does not drop on the floor. This can avoid spills and resin-tray damage.
  7. Do not move the Printer while there is a Resin Tray inside that is filled with material. Even moving the unit a few inches with material inside can cause a material spill.
  8. Uncovered Resin Trays should not be left outside the Printer when containing any amount of 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.
  9. Material overflow from the Resin Tray will be channeled into the catch tray. Discard material and thoroughly clean or replace catch tray. If discarding catch tray, do so according to all government regulations.
  10. Never pour material from the Resin Tray back into its cartridge, nor into any container of common material. Failure to follow this guideline risks contamination, and/or improper mixture, of material in the cartridge.
  11. 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 material leakage. Resin-tray damage can be: membrane puncture, dent, scratch, discoloration, and damage to the frame (cracks, chips, etc.)
  12. If the printer will be sitting idle for more than a few days: Remove the Resin Tray from the printer or cover it with the garage lid. Whenever the Resin Tray is removed, or covered inside the machine, place the red cap onto the material-delivery tube's fitting above the Resin Tray. You should also place the red cap onto the tubing anytime you remove the material-delivery tube from its holder above the Resin Tray.
