A method of making a throttle body assembly, includes casting a main body portion having a passage there through and mounting features for pivotally mounting a throttle valve within the passage. An annular spigot is formed by 3-dimensional printing and is welded to the main body portion in order to provide a quicker less expensive method of prototyping. 制造节气门体组件的方法，包括铸造主体部分，主体部分具有穿透其中的通道和用于枢轴式安装位于通道内的节流阀的安装特征。通过3维打印来形成环形插口，环形插口焊接到主体部分，以提供较为快速和廉价的原型成型方法。
