What is Somos WaterShed XC 1112? Material Overview
Somos WaterShed XC 1112 isn’t just another clear resin. It’s a high-performance liquid photopolymer specifically engineered for Stereolithography (SLA). Engineers choose it because it offers a rare combination of near-colorless transparency and robust mechanical properties. Unlike standard resins that can be brittle or cloudy, this material provides a low-viscosity formula that ensures every fine detail of your CAD model is captured with precision. It’s the go-to solution for projects where you can’t compromise on looks or strength.
The name “WaterShed” is a direct nod to its most famous property: extreme water resistance. It was designed to mimic the durability and look of engineering plastics like PBT and ABS, but with a critical advantage. While many resins absorb moisture and swell over time, Somos WaterShed XC 1112 sheds water effectively. This makes it the industry standard for functional testing where fluid contact or high humidity is a factor. If your prototype needs to survive a flow test or a damp lab, this is the material you want.

The Science of Moisture Resistance
Dimensional stability is the backbone of any successful engineering prototype. When a part absorbs water, it loses its shape and its mechanical strength degrades. Somos WaterShed XC 1112 solves this by maintaining an exceptionally low water-absorption rate. This ensures your parts stay within tight tolerances even in high-humidity environments. It’s the difference between a prototype that fits perfectly on day one and one that still fits six months later. For automotive and electronic housings, this stability is non-negotiable.
Optical Clarity vs. Translucency
There’s a big difference between a part that lets light through and one you can actually see through. As-printed SLA parts usually have a matte, translucent finish due to the natural layer lines of the process. However, the refractive index of this resin is remarkably close to clear plastics like acrylic. With the right post-processing, such as the professional polishing and clear coating services we provide at VPrint3D, these parts transform from “milky” to “glass-like.” This allows for true optical testing of lenses, light pipes, and fluid manifolds.
Technical Performance: HDT, Tensile Strength, and Clarity
When evaluating a material for high-stakes prototyping, the data sheet tells the real story. The Technical Performance of Somos WaterShed XC 1112 is characterized by a tensile strength ranging from 47.1 to 53.6 MPa. This puts it in the same league as many traditional engineering thermoplastics. For you, this means prototypes aren’t just for show. They can handle the mechanical stresses of functional assembly and real-world handling without snapping under pressure.
Thermal stability is another critical factor. With a Heat Deflection Temperature (HDT) of approximately 50°C at 0.45 MPa, this resin is well-suited for automotive interiors and electronic housings that might experience moderate heat. It’s tough enough to maintain its shape where other resins might warp. Plus, an elongation at break of 11% to 20% provides the necessary “give” for snap-fit components. You can assemble and disassemble parts with confidence, knowing the material has the flexibility to resist brittle failure.
Longevity matters, too. Many clear resins turn a sickly yellow after just a few hours of UV exposure. Somos WaterShed XC 1112 is specifically formulated to resist this degradation. It maintains its water-clear appearance far longer than budget SLA materials. This makes it ideal for long-term displays or components that will be used in brightly lit environments.
Achieving Near-Glass Transparency
Clarity isn’t just about the chemistry; it’s about the geometry. We often use thinner layer heights to minimize the “stair-stepping” effect that causes light to scatter. By reducing these internal refractions, the part becomes naturally more transparent. However, to reach true optical-grade results, professional surface finishing is essential. If you’re looking for that perfect glass-like look, our team can help you select the right finishing level for your specific needs.
Moisture and Chemical Resistance Data
One of the most impressive stats for this material is its 0.35% water absorption rate over a 24-hour period. This is significantly lower than standard SLA resins, which often act like sponges. This resistance extends to industrial fluids, too. Whether your part is in contact with engine oils, machine coolants, or mild chemicals, it won’t swell or lose dimensional accuracy. It’s a reliable partner for rigorous R&D environments. If you have a specific testing requirement, you can always reach out to our technicians for expert advice on material compatibility.
Industrial Applications for Somos WaterShed XC 1112
Somos WaterShed XC 1112 has become the go-to material for engineers who need to see what’s happening inside their designs. Its unique balance of clarity and water resistance opens doors that other resins keep shut. From high-tech labs to consumer product testing, its impact is widespread. It’s not just about looking good; it’s about providing the functional visibility required to validate complex engineering concepts.
Fluid flow visualization is one of its most powerful uses. Engineers print transparent manifolds and valves to observe turbulence and flow patterns in real time. Because the material doesn’t swell or cloud when exposed to liquids, it provides consistent results throughout the R&D process. Beyond fluid dynamics, it’s a staple in the automotive and electronics sectors for light pipes and lenses. Designers can prototype complex lighting systems without the high cost of custom-molded optics.
We also see it frequently in FMCG packaging development. Brands use it to test the ergonomics of bottles and to verify how liquid levels appear through the container wall. For electronic housings, clear covers allow technicians to inspect internal component placement and LED alignment without ever opening the device. It’s an invaluable tool for ensuring everything fits and functions as intended before moving to mass production.
Fluid Dynamics and Waterproof Testing
Wind tunnel models and water flow rigs require parts that stay dimensionally stable under pressure. Somos WaterShed XC 1112 excels here. It’s a cornerstone of our rapid prototyping services, allowing teams to iterate on complex fluid systems faster than ever before. If your design involves moving air or water, this material provides the transparency needed to catch design flaws early in the development cycle.
Optical Components and Light Transmission
Designing for internal reflection requires a material with a stable refractive index. While the resin is naturally clear, your design choices matter. We recommend keeping wall thicknesses consistent to avoid clouding in thicker sections. Light pipes should be designed with smooth transitions to maximize light guidance. When you combine smart design with our precision SLA process, you get prototypes that rival production-grade acrylic. Ready to see your design in high-clarity?

Frequently Asked Questions
Is Somos WaterShed XC 1112 truly waterproof?
Yes, it’s one of the most water-resistant resins available for stereolithography today. It features a remarkably low water absorption rate of 0.35% over a 24-hour period. This ensures that your parts don’t swell or warp when used in fluid dynamics testing or high-humidity environments. It’s the industry standard for parts needing long-term dimensional stability and performance in damp conditions where standard resins would fail.
How do I get my 3D printed parts to be completely clear like glass?
You must use professional polishing and clear-coating to achieve near-glass transparency with this material. Parts printed with Somos WaterShed XC 1112 come off the machine with a matte, translucent finish due to natural layer lines. By sanding the surface with progressively finer grits and applying an optical-grade clear coat, light scattering is eliminated. This process transforms the part into a fully transparent component suitable for lenses and light pipes.
Can Somos WaterShed XC 1112 be used for outdoor applications?
It’s suitable for limited outdoor exposure, but it’s not designed as a permanent outdoor solution. While it resists yellowing much better than cheaper SLA resins, all photopolymers eventually degrade under intense sunlight. For parts that need to survive outdoor testing, we recommend applying a UV-protective clear coat. This extra layer significantly extends the part’s life and maintains its clarity against environmental stressors like moisture and UV rays.
What is the difference between Somos WaterShed XC 1112 and standard clear resin?
The main difference lies in its engineering-grade durability and superior moisture resistance. Standard clear resins are often brittle and prone to yellowing or swelling in humid air. Somos WaterShed XC 1112 is specifically formulated to mimic the properties of ABS and PBT plastics. It offers much higher impact strength and stays clear far longer than standard materials. It’s designed for functional testing where accuracy must remain stable over time.
Is this material biocompatible for medical prototypes?
No, this material is not rated for biocompatibility or long-term human contact. It’s a high-performance industrial resin designed for engineering prototypes and fluid-flow analysis. While it’s perfect for printing anatomical models, surgical planning guides, or medical device housings, it shouldn’t be used for implants. Always verify the specific ISO 10993 requirements for your medical project before selecting a material for any clinical or skin-contact applications.
