With the increasing use of glulam in construction industry, low efficiency of material and time in complex glulam production process has been widely recognized. While single curved glulam components are normally achieved with the aid of heavy molds, double curved ones are difficult to be produced directly without massive subtractive fabrication. In this context, a mold-free approach for complex glulam production is proposed, which consists of a mechanical system that spatially shapes the curved beam, and a vision system to inform the fabrication directly with design model. Through the integration of digital design, simulation and physical process, different types of curved glulam could be produced following the same workflow. This approach could eliminate the use of complex molds in curved glulam production, greatly reduce wastes in post-processing process. With the feasibility initially verified through fabrication experiments, the system will be further developed so as to be transferred to industrial practice.

随着胶合木在建筑业中的使用越来越多，在复杂胶合木生产过程中，材料的效率低和时间短已广为人知。尽管单弯的胶合层部件通常借助重型模具来实现，但双弯的胶合层部件很难在没有大量减法制造的情况下直接生产。在这种情况下，提出了一种无需模具的复杂胶合木生产方法，该方法包括在空间上对弯曲光束进行整形的机械系统和通过设计模型直接通知制造过程的视觉系统。通过数字设计，仿真和物理过程的集成，可以按照相同的工作流程生产出不同类型的弯曲胶合层。这种方法可以避免在弯曲胶合胶生产中使用复杂的模具，大大减少了后处理过程中的浪费。通过通过制造实验初步验证了可行性，该系统将得到进一步开发，以便转移到工业实践中。
