“…Another method to embed electronic components is the one presented by Kayfi et al [21], in which copper wire and capacitive sensors are encapsulated within a 3D printed structure; this combination allows practical applications such as material and biomedical sensing. The manufacture of soft robots is another relevant application.…”

Recent interest in additive manufacturing (AM) technologies (also known as 3D printing) has led to embedding multi-material and electronic components into 3D-printed structures. However, current 3D printing technologies fail to provide all the required materials to fabricate complex devices. Besides, the process of inserting individual building blocks into the impression is usually carried out manually. This paper presents the design of a robot that integrates 3D printing and automated assembly. The robot utilises two modules. The first module fabricates the body of a device by using fused deposition modelling (FDM) technology. The second module grasps preassembled building blocks and inserts them into the device. To this end, the feasibility of this integration is validated with the fabrication of a device (non-fabricable with traditional 3D printers) that contains a development board.

“…Consumer-grade 3-D printers are generally equipped with NEMA17-size electric stepper motors driven by a suitable stepper motor driver [10]. Trinamic developed the TMC2130 (Trinamic Motion Control, Hamburg, Germany) which can also detect stalls by means of current sensing [11].…”

Absolute position detection in sensorless electric stepper motors potentially allows for higher space efficiency, improved shock resistance, simplified installation, reduced number of parts and lowered cost.A prototype is demonstrated measuring 42 × 42 × 34 mm 3 with seven coils arranged in a star configuration. The rotor is 25.8 × 12.5 mm 2 and has 51 teeth which are irregularly spaced. At the driver side, the coil currents are measured during motion in order to reconstruct the absolute position of the motor. Calibration and smoothing techniques are used to reduce systematic and stochastic measurement errors, respectively.The motor is able to detect and correct its position after externally-induced stalls at the tested motor speeds from 40 rpm to 108 rpm. The holding torque is 0.23 N m at an armature current of 1 A; on average the torque is 7% lower than that of a reference bipolar stepper motor with the same dimensions.The results show that dynamic position sensing and correction are possible for a range of velocities, but not at standstill. The driver requires seven current sensors and sufficient computational power, and proper calibration of motor intrinsics is required beforehand. The presented technology could make existing 3-D printers and other machines with open-loop stepper motors more robust and increase the range of operating speeds and accelerations, without the adverse side-effects of increased complexity and cost associated with dedicated position sensors.
