Resin 3D printing allows for the creation of models with an impressive level of detail. However, many users are familiar with the challenges of the process: handling strong-smelling chemicals like isopropyl alcohol (IPA), a laborious cleaning process, and the need for a well-ventilated workspace. Water-washable resin was developed to reduce these exact hurdles.
This article serves as a guide for anyone looking to simplify their resin 3D printing workflow. We will highlight the key properties of water-washable photopolymer resin and present a selection of products that enable a more efficient and cleaner process—from material selection to final post-processing.
Before you decide on a product, several technical aspects should be considered to ensure the material is compatible with your printer and meets your requirements.
Most commercially available LCD, DLP, and SLA 3D printers operate with a UV light source that uses a wavelength of 405nm to cure the liquid resin layer by layer. Before purchasing, check that the selected 405nm UV resin is explicitly approved for your printer model. The manufacturer's specifications on the product page or packaging will provide this information. Proper compatibility is the foundation for successful prints.
A key advantage of modern resin formulations is the reduced odour. A low-odour resin significantly contributes to a more pleasant working environment, especially in living spaces or small workshops. Look for terms like "low odour".
The viscosity of the resin also affects the printing process. A low-viscosity resin flows more quickly, making it easier to clean the model and the resin tank. It can also allow for shorter layer exposure times, which speeds up the entire printing process.
The term "water-washable" means that water can be used as the primary cleaning agent for printed objects instead of IPA. This simplifies the process and reduces the need for harsh solvents. For even more thorough and structured post-processing, using a Wash and Cure Station is recommended. These devices combine the washing process and the final UV curing in one compact unit, which not only saves space but also ensures consistent and clean results.
Here is a selection of products geared towards a clean and efficient workflow with water-washable resin.
Why It Stands Out: This resin from Anycubic combines the benefits of being water-washable with technical properties for precise printing results. According to the manufacturer, it has a low viscosity (190–230 mPa·s) for faster printing speeds and a low shrinkage rate (2.2–5.5%), which supports the dimensional accuracy of the printed parts. The formulation is declared as low-odour.
Pros:
Who It's For: Users who create transparent or translucent prototypes, art objects, or functional parts and value a straightforward and clean post-processing workflow.

Why It Stands Out: The Wash & Cure 3 is a 2-in-1 solution that streamlines the entire post-processing workflow. With a large cleaning volume of 4 litres and a maximum cleaning size of 165×100×180 mm, even larger models can be processed with ease. A special feature is the combination of a UV LED panel and an additional gooseneck light, which allows for targeted and uniform curing of hard-to-reach areas.
Pros:
Who It's For: All resin 3D printer users who want to professionalise their workflow, save space, and achieve consistently clean and fully cured results.

Why It Stands Out: This resin offers the same technical advantages as the clear version—water-washable, low odour, and high precision. The grey colour is particularly popular for prototyping and figurine printing, as it visually enhances fine details and surface textures, providing an ideal base for later painting. Its mechanical properties, such as a flexural strength of 48–60 MPa, make it suitable for functional parts.
Pros:
Who It's For: Makers, designers, and engineers who print detailed prototypes, miniatures, or technical models and prefer a straightforward cleaning process. If you plan to paint your models, this is an excellent choice.

Workspace cleanliness is just as important for precise results as cleaning the printed objects themselves. For specialised cleaning solutions that keep your equipment and workspace in optimal condition, you can find a selection of products in our Computer Cleaners category.
Yes, cleaning with tap water is the main advantage of this type of resin. For stubborn residue or a particularly fast clean, IPA (≥95%) can also be used, according to the manufacturer. Proper disposal of the contaminated water is crucial: leave it in a transparent container in the sun until the dissolved resin cures. The solid material can then be disposed of as plastic waste, and the water can then be poured down the drain.
Most of these resins are marketed as "low-odour," not completely odourless. Compared to traditional standard resins, the odour is significantly reduced, making work in enclosed spaces more pleasant. Nevertheless, it is recommended to ensure good ventilation in the workspace.
A dedicated station is not strictly necessary; cleaning can also be done manually in a container of water, and curing can be done under a UV lamp or in the sun. However, a Wash and Cure Station automates and standardises this process. It ensures more uniform cleaning and curing, reduces direct contact with chemicals, and leads to a cleaner and more efficient overall result.
