About the Material

Accura 25 is a durable and flexible SLA 3D printing material. With a Shore D Hardness of 80, Accura 25 can be used as an alternative to machined Polypropylene and ABS. It’s ideal for snap-fit part designs, as a master pattern for urethane casting, and conceptual modeling. Accura 25 can be used for functional prototyping or end-use parts, but parts with this purpose are typically restricted to short production runs. In terms of aesthetics, the material has excellent resolution, dimensional accuracy, and can be primed and painted after printing.

Material Properties

Tensile Strength

38 MPa (5510 psi)

Elongation at Break

16%

Modulus of Elasticity

1620 MPa (325ksi)

Flexural Strength

57 MPa (8267 psi)

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
(254 x 254 x 254 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.

Best Practices for Adding Ribs and Gussets to 3D Printed Parts for Structural Integrity

When designing plastic components, it’s often necessary to add ribs and gussets to improve the stiffness and strength of load-bearing features. This reduces material volume and optimizes print time for 3D printed parts, since it takes longer to make these features solid structures (print time is largely driven by the volume of material for a […]
