After an incomplete print, resin may be contaminated with cured resin debris. For the best print quality on subsequent prints, filtering the resin in the tank removes particles and will lead to better prints and higher surface quality.
Consider filtering the resin tank when:
- A print has failed, either completely or partially
- Layers or pieces of cured resin stick to the bottom of the tank
- You can visually see particles in the tank
Resources for Filtration
- Paint or oil filter with ~190 micron mesh size
- Formlabs Finish Kit Scraper
- Opaque plastic container
- Optional: ring stand - simplifies the filtering process and reduces the risk of spillage
Steps to Filter
- Suspend the filter above the plastic container, using a ring stand or by placing directly on top.
- Wear gloves to remove the tank and wiper from the Form 2. Place the wiper aside on a protected surface.
- Hold the edge of the tank, taking care not to touch the tank’s optical window. Tilt the resin tank with the spout aligned directly above the filter. Pour the resin through the filter, into the disposable container.
- Use the scraper tool included with the Formlabs Finish Kit to move across the resin tank’s silicone layer, pulling resin toward the spout.
- Once all resin passes through the filter, dispose of the dirty filter and pour the resin back into the tank.
