To wash and cure resin prints, remove uncured resin with the solvent or method specified for your resin, let the print dry fully, then cure it as directed. Wear suitable gloves, protect your work area, and follow the resin and solvent safety instructions.

The right setup depends on your resin, the size and shape of your parts, and how often you print. A small container and separate curing method may suit occasional prints, while a wash and cure station can organize repeat jobs and larger batches.

How do you wash and cure resin prints step by step?

Wash the print, inspect it for residue, let it dry, then cure it according to the resin instructions. Keep uncured resin and contaminated solvent off your skin and work surfaces.

1. Read the resin instructions and safety data sheet. Check which wash method and cure process they call for.
2. Put on the protective equipment required by the resin and solvent instructions, and cover the work area.
3. Remove the print carefully over the protected surface.
4. Wash it using the recommended method. Move the part gently so the wash reaches its exposed surfaces.
5. Inspect crevices, undersides, and support areas for residue.
6. Let the print dry fully, then cure it using the specified time and method.

Don't choose one wash or cure time for every material. Resin type, part geometry, and the equipment you use can change the instructions.

What should you prepare before washing a resin print?

Set up a ventilated work area, suitable gloves, a protected surface, and the wash supplies specified for your resin. Keep food, drinks, children, and pets away while you work.

Liquid resin and resin-coated parts can irritate or sensitize skin. Formlabs advises wearing gloves when handling liquid resin or unwashed parts, and washing skin with soap and water if uncured resin gets on it.

Read the Formlabs resin safety guidance and your resin’s safety data sheet before handling it. If you use isopropyl alcohol (IPA), keep it away from ignition sources and follow its safety instructions; OSHA’s chemical data page identifies IPA as a flammable liquid.

Keep clean and used wash liquid separate if your process calls for multiple rinses. Label containers clearly, close them when they aren't in use, and follow local rules for handling contaminated materials.

Which wash method suits your prints?

Use the wash method and solvent your resin instructions recommend. If those instructions allow a two-stage wash, an initial rinse followed by a cleaner final rinse can help keep the last wash from carrying as much surface resin back onto the part.

Agitate gently so solvent reaches exposed surfaces, including small details and the spaces between supports. Avoid a longer soak than the instructions recommend, since extended solvent exposure can affect some materials.

Formlabs recommends considering part geometry and multiple rinse stages where appropriate in its best practices for washing prints. Check holes, grooves, deep recesses, and support attachment points after washing because they can hold liquid.

For hollow models, check the design and resin guidance for drainage and cleaning instructions. Liquid resin trapped inside can remain even when the outside looks clean, so plan access and drainage before printing where possible.

Why should you dry a resin print before curing?

Let the print dry fully before curing it. Solvent left on the surface or in recessed areas can affect the finish and make it harder to judge whether the part is clean.

Check seams and narrow openings as well as broad surfaces. If a part still looks wet, give it more time and consult the resin instructions; use gloves when handling unwashed or resin-contaminated parts.

Don't rush from washing straight to curing to save a few minutes. A deliberate inspection and drying step helps you catch residue before it becomes harder to remove.

How do you cure resin prints evenly?

Use the cure method and time specified for your resin, and expose the relevant surfaces as directed. Reposition the part only when your curing setup or resin instructions call for it.

A dedicated station combines washing and curing equipment in one workspace. For larger prints or batches, the Anycubic Wash and Cure 3 Plus has a 7.6 L washing basket and a dual-layer curing platform.

The Anycubic Wash and Cure 3 has a 4 L cleaning bucket and adjustable basket heights. It is sized for LCD printers up to 7.3 inches, making it a more compact fit for smaller models and platforms.

The Elegoo Mercury Plus 3.0 has a 7.5 L cleaning capacity, basket and hanging wash modes, and a 360-degree curing setup. The hanging option can help when you want to wash a platform without placing it in the basket.

These stations handle different print sizes and washing needs, but they don't replace the resin instructions. Choose based on the parts you make and the space you have, then use the station manual to set up each step.

What mistakes should you avoid when washing and curing?

Don't skip drying, use an unapproved solvent, or guess at cure times. These shortcuts can leave residue behind or produce a result that doesn't match the resin instructions.

Avoid handling uncured prints with bare skin, leaving solvent open near an ignition source, or pouring used solvent down a drain. Follow the resin and solvent safety instructions, and check local rules for contaminated materials.

Don't assume a clean-looking outer surface means a hollow print is clean inside. Plan for drainage, inspect accessible openings, and follow the resin guidance for cleaning the part's interior.

A final inspection before curing is useful: check for shiny liquid, residue in recesses, or uncured material near supports. If you find any, return to the appropriate cleaning step before curing.

Which wash and cure station should you choose?

Match the station to your printer size, typical part dimensions, and batch size. A station that's too small can make the workflow awkward, while extra capacity may not help if you only clean small parts.

Choose the Anycubic Wash and Cure 3 Plus if your prints or platforms need more room, or if you cure several models on its double-layer platform. Its basket supports printers up to 10.6 inches, so it suits a larger resin setup.

Pick the Anycubic Wash and Cure 3 for a more compact workflow with printers up to 7.3 inches. Skip it if your usual prints or platform exceed its size range.

Choose the Elegoo Mercury Plus 3.0 if you want both basket and hanging wash modes, especially for cleaning a platform. Its larger cleaning and curing capacity suits bigger models; skip it if its footprint and capacity are more than your workspace needs.

If you don't print often, a compatible container and separate curing method may be enough. Whatever setup you choose, confirm it fits your parts and follow both the station manual and resin instructions.

Do you need a new resin printer as well?

A wash and cure station is post-processing equipment; a resin printer is a separate purchase. You don't need a new printer just to wash and cure prints from a compatible machine.

The Elegoo Mars 5 Ultra is a printer, not a wash and cure station. Its 9K mono LCD and 18 μm XY resolution make it relevant if you're also choosing a printer for detailed models.

If you need a printer, compare options in our guides to the best resin 3D printers for beginners and best resin 3D printers for miniatures. For a wider setup checklist, see what you need to start 3D printing at home, or browse the resin and detail guides.

How should you choose a setup for washing and curing resin prints?

Pick a container and curing method for occasional small prints, or a station when repeat washing, platform cleaning, or batch curing matters. Size the equipment around the parts you actually print, then follow the resin's steps for washing, drying, and curing.

For larger batches, compare the Anycubic Wash and Cure 3 Plus with the Elegoo Mercury Plus 3.0 by capacity and washing modes. For smaller printers, the Anycubic Wash and Cure 3 offers a more compact basket and adjustable heights.

The reliable sequence is wash off uncured resin, inspect, dry completely, and cure as directed. Choose equipment that fits your print size and workspace, and use the resin instructions to set the process.

Frequently asked questions

How long should you wash a resin print?

Use the wash time in the resin and washing station instructions. The right time depends on the resin, solvent, part shape, and washing method.
