摘要：三维重建及3D打印技术目前是较为前沿的技术，逐渐吸引了大众的眼球，成为国内外学者研究的重点。由于三维重建与3D打印技术与所需创造的物体结构复杂程度无关，所以现阶段我国创造出利用三维技术和3D打印技术形成成形块用于一种新型焊接定位的技术，从而达到高精度的定位和焊接，快速高效完成产品，提高产品质量，从而实现了现代汽车产业复杂钣金的快速高质量制造，三维重建及3D打印技术还可以应用于多方面焊接工作中，可以大幅度提高焊接精准度。

Abstract： Three-dimensional reconstruction and 3D printing technology are currently relatively cutting-edge technologies， which have gradually attracted the attention of the public and become the focus of research by domestic and foreign scholars. Since three-dimensional reconstruction and 3D printing technology have nothing to do with the complexity of the object structure to be created， at this stage， my country has created a new type of welding positioning technology that uses three-dimensional technology and 3D printing technology to form a shaped block to achieve high-precision positioning And welding， complete products quickly and efficiently， and improve product quality， thereby realizing the rapid and high-quality manufacturing of complex sheet metal in the modern automobile industry. Three-dimensional reconstruction and 3D printing technology can also be applied to various welding tasks， which can greatly improve welding accuracy.

在我国汽车领域行业中，汽车零件的批量生产前会经过一系列的试制环节，相对于正式批量生产来说，试制环节具有一套比较完整的流程，生产周期长，对其投入的资金力度大。但这些满足不了现代社会的需求，零件在批量生产的过程中，往往更希望达到快速、低成本、高质量的标准。因此，对零件生产采用三维重建和3D打印技术，可以进一步缩短复杂钣金的生产周期，降低了复杂钣金在生产时所花费的费用;采用三维重建和3G打印技术，对复杂钣金件进行生产，可以达到高效生产，低经济成本生产等一系列人们所追求的目标。下面通过用三维重建和3D打印技术在汽车仪表台金属管梁支架试制方面的应用为例，来探索三维重建及3D打印技术在复杂钣金试制焊接工装中的实践应用。……
