Harztank
| Item | Description | Image |
|---|---|---|
| Resin tank | Resin is dispensed out of the resin cartridges into the resin tank. During a print, two lasers pass upwards through the flexible film of the resin tank and cure resin onto the build platform to form a printed part. Only use approved materials and procedures to clean the resin tank. | ![]() |
| Tank handles | Handles on each side of the resin tank allow for easy insertion, removal, and carrying of the resin tank. Use the tank handles to avoid touching the resin tank’s underside, as fingerprints leave smudges that obstruct the optical path. | ![]() |
| Tank spout | A spout at the right of the resin tank sits underneath the cartridge dispense hole and receives resin from the resin cartridge. | ![]() |
| Flexible film | A durable, dual-layer film comprises the resin tank’s underside. Parts print in the resin-filled gap between the flexible film and the build platform. The print quality depends on the flexible film being clean and clear of damage and debris. | ![]() |
| Resin tank RFID sticker | Each resin tank has an RFID sticker attached to the back wall of the tank frame. The printer reads the RFID sticker to detect the unique tank ID and current resin type. | ![]() |
| Mixer | Each resin tank includes a mixer that improves print consistency by clearing the build area and circulating the resin. The mixer moves with the LPU housing via magnetic coupling and rests at the right side of the resin tank when not in use. Scrapers on the top and bottom of the mixer clear the build platform and flexible film, respectively. | ![]() |
| Tank case | Each resin tank includes a container and a lid for storing the resin tank when not in use. | ![]() |
| Tank tool | A two-part scraper for inspecting and cleaning the resin tank interior. Separate tool for scraper function or combine for tongs. Together with the cleaning mesh, this is the only tool to clean the flexible film inside the resin tank. | ![]() |
