What You’ll Need

• Mixing Buckets Kit for Epoxy Resin Art – Easy Clean Flexible Design: collect and store unused resin or waste safely.
• Pure Isopropyl Alcohol 99.9% – 1000ml Bottle for Epoxy Resin Projects & DIY: suitable for cleaning resin residues from the tank if required.
• Strong Technical Degreaser for Resin Projects – 100% Natural Formula: for removing stubborn grease or resin build-up in or around the tank area if necessary.
• Nitrile gloves and protective eye-wear
• Lint-free cloths or paper towels
• A well-ventilated workspace

Step 1: Prepare the Workspace and Protect Yourself

Begin by ensuring your workspace is clean and free from clutter. Wear gloves and protect skin as uncured resin can irritate or stain. Position the printer in a well-ventilated area to avoid inhaling any fumes, and have a Mixing Buckets Kit at the ready for pouring out or temporarily storing leftover resin. Place absorbent materials or paper towels nearby in case of spills.

Step 2: Safely Remove the Resin Tank

Lift the Form 3 printer cover and gently disengage the resin cartridge if present, following manufacturer guidelines. Carefully unlock and lift the resin tank out of the printer, holding it level to prevent any drips. Always handle the tank by its dedicated grips or edges to minimise the risk of contamination and spillage. Do not pour resin down the drain as this may harm plumbing and the environment.

Step 3: Transfer the Resin and Clean Residues

Pour unused resin into a clean container such as a Mixing Buckets Kit; store reusable resin in an opaque, sealed bottle, labelled and away from sunlight. If the tank contains cured residue or stubborn marks, carefully wipe with lint-free cloths. For tacky or sticky residues, dampen a cloth with Pure Isopropyl Alcohol 99.9% and gently clean—avoid saturating the tank to protect its film or seals. When handling more persistent contaminants like grease or ink, a sparing application of Strong Technical Degreaser can be effective. Wipe thoroughly and allow the tank to air dry before reinstallation or storage.

Step 4: Dispose of Waste Responsibly

Gather any spent resin, cleaning materials, and contaminated gloves for proper disposal in accordance with local hazardous waste regulations. Never dispose of liquid resin with household rubbish or down sinks. Work in a ventilated area and seal waste bags tightly before removal. Document the cleaning and emptying process so all users of the Form 3 know the tank’s current state.

Tips, Common Mistakes, and Troubleshooting

Always check for cured resin stuck to the tank window, as missing this can affect future prints. Avoid using excessive force or sharp tools inside the tank to prevent punctures. Double-check that all surfaces are dry and residue-free before reinstalling the tank. If streaks or cloudiness remain after cleaning, repeat a wipe-down with isopropyl alcohol or degreaser, but do not scrub aggressively. Familiarise yourself with Form 3’s manufacturer recommendations for tank maintenance and storage.
