Technical specifications
Windform SL is the twelfth material in the Windform TOP-LINE range for selective laser sintering. Its exceptional lightness, with a density of 0.87 g/cc, coupled with carbon fiber reinforcement, positions it as an optimal choice for applications demanding lightweight components without compromising structural integrity.
The stiffness of Windform SL is evident in key metrics such as the XY-axis Tensile Strength at 52.82 MPa and the XY-axis Tensile Modulus at 4033.40 MPa. These properties empower the material to maintain form and structural stability even under substantial loads, ensuring reliable performance in demanding scenarios.
Windform SL distinguishes itself with notable heat resistance, boasting a Heat Distortion Temperature (HDT) of 182.5°C at 1.82 MPa. This feature makes the material suitable for operational contexts requiring superior thermal stability, preserving its performance in adverse environmental conditions.
Impressive impact resistance is another strength of Windform SL, as evidenced by Charpy and Izod tests, showcasing its ability to withstand dynamic forces without compromising structural integrity.
The post-processing surface finish is equally noteworthy, with Ra values of 5.44 µm after the SLS process, 1.56 µm after manual finishing, and 0.83 µm after CNC machining. These values ensure the achievement of smooth and precise surfaces, establishing Windform SL as a technologically advanced material for demanding applications.
Applications
Windform SL finds extensive applications in the drone/UAV sector, such as in the manufacturing of the central body and arms. The material’s lightweight nature translates to increased flight autonomy, while its stiffness provides the necessary robustness to withstand various operational conditions. Furthermore, its high-temperature resistance allows greater versatility in scenarios where temperatures may vary significantly.
