Let’s delve into the science behind these Elegoo Water Washable Resin products and compare them with traditional resins.

The Science Behind Water Washable Resins

Water washable resins are a type of photopolymer resin that cures (hardens) when exposed to a specific wavelength of light, usually UV light. The monomers and oligomers in the resin form cross-links when exposed to this light, transitioning from a liquid to a solid state.

The unique aspect of the best water washable resin products lies in their formulation, which incorporates water-soluble components. Traditional resins require isopropyl alcohol (IPA) and other solvents to eliminate uncured resins. However, water washable resins can be cleaned using water because their resin formulation contains hydrophilic components. These components ensure that the uncured resin can be dissolved or loosened by water, making post-processing significantly easier and safer.

Comparison of the Chemistry of Water Washable Resins versus Traditional Resins

  1. Solubility

Traditional photopolymer resins typically require organic solvents like isopropyl alcohol for cleaning because they do not have components that are water-soluble.

The formulation of water washable resins includes water-soluble components, allowing for cleaning with water.

  1. Cross-linking Mechanism

Both traditional and water washable resins rely on the same mechanism of cross-linking under UV light exposure. However, the formulation differences may result in varying degrees of cross-linking density, which could affect the mechanical properties of the final print.

  1. Safety and Environmental Impact

The requirement for organic solvents in post-processing traditional resins can pose safety and environmental hazards. Proper disposal of used solvents is crucial to minimize environmental impact.

The ability to clean with water reduces the safety risks associated with handling organic solvents and lessens the environmental burden.

  1. Mechanical and Optical Properties

The variation in chemistry can also affect the mechanical and optical properties of the final print. For instance, water washable resins may offer different levels of clarity, flexibility, or strength compared to traditional resins.

  1. Cost and Accessibility

Customary resins tend to be more cost-effective and readily available because they have been in the market for many years. Conversely, water washable resins provide long-term cost savings owing to their ease of use and the decreased post-processing times.

The exploration into the chemistry of water washable resins unveils a horizon of possibilities in the realm of 3D printing.
