As high-precision additive manufacturing becomes more deeply integrated into the development of end products, the demand for engineering-grade materials with exceptional optical performance continues to grow. NextShapes has optimized its Precision Clear 3D resin specifically for industrial-grade 355nm SLA 3D printing technology. This material aims to address the core challenges in professional fields where transparency is critical for visualization, optical testing, and appearance validation: achieving the purity and light transmittance that closely matches optical glass.

"This is not just a simple upgrade. When transparency itself becomes a function, the purity of the material directly determines the credibility of the prototype."
— Senior Engineer, Optical Laboratory

Precision Fluid Dynamics Visualization Models

In the automotive and aerospace industries, transparent models used for flow field visualization must be flawless internally. Any tiny bubbles or light scattering can distort observations such as Particle Image Velocimetry (PIV). A system engineer responsible for fuel flow analysis in engines faced this challenge.

"Traditional transparent 3D printing resins often introduce cloudiness or bubbles when printing complex internal channels, making it impossible to trust visualization results. Post-processing polishing often compromises internal geometric accuracy."
— Powertrain System Engineer

The team used Precision Clear 3D resin to successfully print an integrated flow channel model with intricate internal cavities. With a light transmittance of up to 90.8% and almost no bubbles, the model met the initial requirements for laser flow field observations without excessive polishing. More importantly, its low viscosity ensured that uncured resin left in fine structures was thoroughly washed out, preventing post-cleaning yellowing or cracking, thus ensuring the authenticity of the data.

"Precision Clear has made us believe for the first time that SLA 3D printed transparent parts can be directly used for rigorous qualitative flow field analysis. It provides not just 'looks transparent', but 'functional transparency'."

Medical Anatomical Models and Surgical Guides

In surgical planning and medical education, highly transparent anatomical models clearly demonstrate the spatial relationships between lesions and surrounding tissues. A bioengineering expert needed to print a transparent brain model for pre-surgery simulation that could withstand high-temperature sterilization.

"The model must be absolutely pure, colorless, and able to endure sterilization cycles. Any discoloration or yellowing would lead to misjudgment of tissue layers, which is unacceptable."
— R&D Director, Medical Device Company

Previously used materials often yellowed or became brittle after high-temperature sterilization. Precision Clear, with its excellent post-curing stability and colorless properties, allowed models to retain excellent transparency and dimensional stability even after autoclave sterilization. Moreover, its easy-to-clean properties significantly reduced residuals at support contact points, resulting in smoother, cleaner surfaces, especially in intricate areas such as blood vessels and nerves, thereby improving the surgeon’s experience and diagnostic accuracy.

"For demanding medical visualization applications, consistency and biocompatibility of the material are equally important. The performance of Precision Clear after multiple sterilizations provides us with a reliable new option for creating long-lasting educational models and custom surgical guides."

Transparent Casings and Optical Components for Consumer Electronics

The consumer electronics industry places high demands on transparent prototypes, requiring them to have a high-quality visual appeal, be free of discoloration and fingerprints, and quickly validate internal structural layouts. A design manager responsible for smart wearable devices was looking for a material suitable for market demonstration and optical testing of transparent casings.

"Our transparent casing is not only an aesthetic part but also integrates optical sensors. The material must be clear both inside and out, with uniform light transmission, free of swirl marks or cloudiness, as these would affect sensor calibration and first impressions."
— Design Manager, Consumer Electronics Company

The casing prototype 3D printed with Precision Clear exhibited extremely high transparency and color consistency after a simple polishing process, allowing the internal component layout to be clearly visible. Its outstanding light transmittance ensured that optical sensor performance testing could be accurately performed during the prototype stage. The entire post-processing flow—from removing the build platform to cleaning and final curing—was significantly expedited due to the material’s easy cleaning properties, shortening the design validation cycle.

"From design review to functional testing, Precision Clear has provided a high-quality, transparent solution throughout. It transformed our transparent prototype from a 'model' to a 'working prototype' that is incredibly close to the final product."
