About the Material

Accura 25 is a photopolymer resin used in Stereolithography (SLA) 3D printing technology. It is known for its high transparency and clarity, making it ideal for applications where optical properties are essential. Here are some common applications for Accura 25 in 3D printing:

Optical Prototypes: Accura 25 is often used to create optical prototypes and components, such as lenses, prisms, and light guides, to test and validate optical designs.

Clear and Transparent Parts: It’s suitable for producing clear and transparent parts for various applications, including windows, covers, and enclosures.

Medical Devices: Accura 25 can be used in the production of medical devices that require transparency and biocompatibility, such as optical components for diagnostic equipment and clear housings for medical devices.

Consumer Electronics: Accura 25 is used in the production of clear or transparent casings, covers, and screens for consumer electronic devices, including smartphones, tablets, and wearables.

Aerospace Components: In aerospace applications, where optical clarity is critical, Accura 25 can be used to create components like windows, lenses, and sensor covers.

Automotive Lighting: Accura 25 is suitable for producing lenses and covers for automotive lighting systems, including headlights, taillights, and signal lights.

Architectural Models: Architects and designers use Accura 25 to create architectural models with clear windows and facades to accurately represent building designs.

Display Prototypes: Accura 25 is used for creating prototypes of displays, screens, and visual communication systems where optical clarity is necessary.

Lighting Prototypes: It’s used to prototype lighting fixtures, light diffusers, and optical elements in the design of custom lighting solutions.

Art and Sculptures: Artists and sculptors use Accura 25 to create clear or translucent art pieces and sculptures.

Educational Models: Accura 25 is used in educational institutions to create models that demonstrate optical phenomena and principles.

Fluid Visualization Models: In scientific and engineering research, Accura 25 is employed to create clear models for visualizing fluid flow, heat transfer, and other phenomena.

Microfluidics: Accura 25 is suitable for producing microfluidic devices used in various research and medical applications.

Optical Test Components: It’s used to create test components and fixtures for optical testing and calibration.

Accura 25’s excellent optical properties, including high clarity and transparency, make it a valuable material for applications where visual and optical performance are essential. It’s important to note that post-processing steps such as polishing or coating may be required to achieve the desired optical finish.

Material Finish

Accura 25 has a semi-glossy, white appearance. Surfaces in contact with support structures may have a slightly rougher texture as a result of support removal.

Design Recommendations

Max Part Size [x, y, z]

10 x 10 x 10 inches
(635 x 736 x 533 mm)

Min Clearance + Gaps for Fit

0.5 mm between parts that need to be assembled
0.2 mm between shells of an interlocking part

Min Wall Thickness

1 mm

Text Guidelines

Embossed features should be at least 0.1 mm from the surface below. Debossed features should be at least 0.4 mm wide to avoid the opposing walls from fusing together.


3D Printing vs Injection Molding

3D printing and injection molding are each used to produce plastic parts. However, these processes are not mutually exclusive because some projects that begin with 3D printing end with injection molding.  3D printing is typically used for early-stage prototypes, evolving designs, and part geometries that can’t be produced with other methods. Because this form of […]
