Voluminous component: Cardan suspension
The range of parts that can be manufactured with PBF is expanded by the 500 °C preheating option of the TruPrint 5000. The residual stress of the parts is significantly reduced, especially in the case of volume changes and support connections.
The 500 °C preheating feature makes it possible to print the Cardan bearing, also called a gimbal. This significantly reduces the residual stress in titanium components, thereby opening up entirely new possibilities in design, especially in the construction of more solid components.
3D printed cardan suspension with 500 °C preheating
The gimbal printed with 200 °C preheating has significant internal stresses. Compared to a temperature of 500 °C, the preparation and post-processing effort is significantly higher due to the increased need for simulations and support structures.
At 500 °C, the internal stress in the titanium component is significantly reduced
