这项研究提出了一种新颖的和破坏性的方法，同时设计和结构优化的零件制造使用纯添加剂，纯减法和混合添加剂-减法制造工艺（HASP）。这项研究是为了满足越来越多的需求，能够有信心地说，一个特定的零件设计可以通过一个特定的过程制造。这被认为是增材和混合制造工艺有利可图的主要障碍。通过描述已知的部分约束和组成制造过程的机制（限制），部分设计使用生物启发的多智能体系统称为“混合蚂蚁”。通过将制造过程抽象为一组规则，限制材料的加工方式和加工位置，混合蚂蚁创建的所有零件几何形状在当前的制造能力描述下都是固有的“可制造”。从这个系统中可能引出新知识的可能性是一个令人兴奋的新范例，它可能会改变未来开发增材（或混合）制造过程的设计方式。正如本文所示，混合蚂蚁是一个闭环系统，它生成部分的几何形状，然后使用有限元方法评估这些几何结构的结构性能。应力值然后用于下一个循环迭代中，以无限细化几何体。这个系统类似于蚂蚁（或白蚁）的巢穴形态发生，其中巢穴布局针对温度调节和通风进行了优化。在这项研究中，温度调节类似地交换为应力，用于工程部件的结构优化。
This research presents a novel and disruptive approach to the simultaneous design and structural refinement of parts manufactured using purely additive, purely subtractive and hybrid additive-subtractive manufacturing processes (HASPs). This research is responding to the increasing need to be able to state with confidence that a particular part design can be manufactured by a particular process. This is viewed as a major barrier to the profitable exploitation of additive and hybrid manufacturing processes. By describing the known part constraints and the mechanisms (limitations) of constituent manufacturing processes, parts are designed using a bio-inspired multi-agent system called ‘Hybrid Ants’. By abstracting manufacturing processes into a set of rules that limit how and where material can be processed, all part geometries created by the Hybrid Ants are inherently ‘manufacturable’ under the current description of the manufacturing capability. The possibility that new knowledge may be elicited from this system is an exciting new paradigm, which could change the way design for additive (or hybrid) manufacturing processes is developed in the future. As will be shown throughout this paper, Hybrid Ants is a closed-loop system, which generatively creates part geometries and then appraises these geometries for structural performance using the finite element method. Stress values are then used in the next loop iteration to refine the geometry ad infinitum. This system is akin to ant (or termite) nest morphogenesis, where nest layouts are optimised for thermoregulation and ventilation. In this research, thermoregulation is analogously exchanged for stress for structural optimisation of engineering components.
