我们引入了一种新形式的低成本3D打印机，用于打印带有缠绕线圈的交互式机电对象。该打印机的核心是一种用于在五自由度（5DOF）熔融沉积成型（FDM）3D打印机内沉积金属丝的机制。铜线可以与这种机制一起使用，以形成线圈，当电流通过线圈时，线圈会感应磁场。软铁丝还可以用于形成具有高磁导率的部件，从而能够将这些磁场成形并引导到需要它们的地方。当使用结构塑料元件制造时，这允许简单但完整的定制电磁设备被3D打印。作为例子，我们展示了一个螺线管致动器的幸运猫雕像的手臂，一个6极步进电机定子，磁阻电机转子和磁流体显示器的制造。此外，我们展示了如何印刷线圈，产生小电流响应用户的动作，可用作输入传感器在交互式设备。
We introduce a new form of low-cost 3D printer to print interactive electromechanical objects with wound in place coils. At the heart of this printer is a mechanism for depositing wire within a five degree of freedom (5DOF) fused deposition modeling (FDM) 3D printer. Copper wire can be used with this mechanism to form coils which induce magnetic fields as a current is passed through them. Soft iron wire can additionally be used to form components with high magnetic permeability which are thus able to shape and direct these magnetic fields to where they are needed. When fabricated with structural plastic elements, this allows simple but complete custom electromagnetic devices to be 3D printed. As examples, we demonstrate the fabrication of a solenoid actuator for the arm of a Lucky Cat figurine, a 6-pole motor stepper stator, a reluctance motor rotor and a Ferrofluid display. In addition, we show how printed coils which generate small currents in response to user actions can be used as input sensors in interactive devices.
