This study explores aerosol jet‐printed (AJP) surface roughness, its effects on the performance of microwave electronics, and its process contributors. First, an electromagnetic model is vetted for AJP's unique roughness signature. Simulations are built which show process‐induced roughness is as significant as conductor resistivity in driving microwave

This study investigates the effect of a NiAl coating on additively manufactured (AM) IN939 to improve its cyclic oxidation resistance at 1050 °C. The coating promotes protective α‐Al2O3 formation, allowing durability for up to 240 cycles, while uncoated AM‐IN939 experiences spallation and weight loss due to nonprotective oxides.

Data-Driven Extrusion Force Control Tuning for 3D Printing [PDF]
The quality of 3D prints often varies due to different conditions inherent to each print, such as filament type, print speed, and nozzle size. Closed-loop process control methods improve the accuracy and repeatability of 3D prints. However, optimal tuning of controllers for given process parameters and design geometry is often a challenge with manually

Fabrication of Poly (ε-Caprolactone) 3D scaffolds with controllable porosity using ultrasound [PDF]
3D printing has progressed significantly, allowing objects to be produced using a wide variety of materials. Recent advances have employed focused ultrasound in 3D printing, to allow printing inside acoustically transparent materials. Here we introduce a Selective Ultrasonic Melting (SUM) method for 3D printing of poly ({\epsilon}-caprolactone) (PCL ...

Laboratory protocols for producing thin‐film pH electrodes for sterilized single‐use technologies have been successfully developed into a semiautomated workflow, with higher throughput and precision of membrane thickness. Accuracies are within 0.05 pH units versus ground truth, and uncertainty analysis reveals the largest sources of error to be derived

When realized as inserts in high‐pressure die casting, aluminum cooling channels for electric powertrain components and similar applications typically require a stabilizing filler to survive the process. The present study investigates relinquishing this filler using additively manufactured inserts promising performance improvements.

Capillary Flow Printing of Submicron Carbon Nanotube Transistors [PDF]
Although printed transistors have a wide range of applications, the limited resolution of printing techniques (10-30 um) has been a barrier to advancement and scaling, particularly down to submicron dimensions. While previous works have shown creative approaches to realizing submicron channel lengths with printing, reliance on chemical processes unique
