“…Further advancements of the AJ-P technology consist of collimated aerosol beam direct writing (CAB-DW), a modification developed by OPTOMEC and North Dakota State University that utilizes an optimized nozzle design to enable improved resolution and the writing of structures smaller than 5 μm, , and electro-aerodynamic jet printing (e-jet printing) . The latter technology combines the standard aerosol jet concept with the addition of an applied electric potential, charging the aerosol particles with respect to the substrate surface.…”

Additive manufacturing (AM) alias 3D printing translates computer-aided design (CAD) virtual 3D models into physical objects. By digital slicing of CAD, 3D scan, or tomography data, AM builds objects layer by layer without the need for molds or machining. AM enables decentralized fabrication of customized objects on demand by exploiting digital information storage and retrieval via the Internet. The ongoing transition from rapid prototyping to rapid manufacturing prompts new challenges for mechanical engineers and materials scientists alike. Because polymers are by far the most utilized class of materials for AM, this Review focuses on polymer processing and the development of polymers and advanced polymer systems specifically for AM. AM techniques covered include vat photopolymerization (stereolithography), powder bed fusion (SLS), material and binder jetting (inkjet and aerosol 3D printing), sheet lamination (LOM), extrusion (FDM, 3D dispensing, 3D fiber deposition, and 3D plotting), and 3D bioprinting. The range of polymers used in AM encompasses thermoplastics, thermosets, elastomers, hydrogels, functional polymers, polymer blends, composites, and biological systems. Aspects of polymer design, additives, and processing parameters as they relate to enhancing build speed and improving accuracy, functionality, surface finish, stability, mechanical properties, and porosity are addressed. Selected applications demonstrate how polymer-based AM is being exploited in lightweight engineering, architecture, food processing, optics, energy technology, dentistry, drug delivery, and personalized medicine. Unparalleled by metals and ceramics, polymer-based AM plays a key role in the emerging AM of advanced multifunctional and multimaterial systems including living biological systems as well as life-like synthetic systems.

“…Aerosol. CAB-DW is a technology developed at NDSU [9,17] which consists of a three-component converging-diverging-converging nozzle ( Figure 2) capable of reducing depositions from the Aerosol Jet system to 5 μm by further collimating and focusing the aerosol beam. Other characteristics of CAB-DW are nearly identical to that of Aerosol Jet.…”

“…Benefits associated with A-DW are a consequence of the ability to print lines as thin as 5 μm which affords a reduction in shadowing, series resistance, and production costs. Due to the noncontact approach utilized with aerosol spray, thinner wafers (i.e., 100 μm) can be used without the breakage associated with contact print methods such as screen printing giving a higher number of solar cells per Si single crystal boule [17,108]. We printed silver-based traces as thin as 7 μm on heterojunction with intrinsic thin layer (HIT) solar cells produced in collaboration with NREL.…”

“…We printed silver-based traces as thin as 7 μm on heterojunction with intrinsic thin layer (HIT) solar cells produced in collaboration with NREL. The HIT cells utilize an indium tin oxide ITO transparent conducting oxide (TCO) lateral transport layer, so no burn-through was required [17,109]. Results of this work concluded that an improvement in solar cell efficiency is realized when approximately 5 μm traces are used in place of 90 μm traces with similar geometric shadowing.…”

Aerosol-based direct-write refers to the additive process of printing CAD/CAM features from an apparatus which creates a liquid or solid aerosol beam. Direct-write technologies are poised to become useful tools in the microelectronics industry for rapid prototyping of components such as interconnects, sensors, and thin film transistors (TFTs), with new applications for aerosol direct-write being rapidly conceived. This paper aims to review direct-write technologies, with an emphasis on aerosol-based systems. The different currently available state-of-the-art systems such as Aerosol Jet CAB-DW, MCS, and aerodynamic lenses are described. A review and analysis of the physics behind the fluid-particle interactions including Stokes and Saffman force, experimental observations, and how a full understanding of theory and experiments can lead to new technology are presented. Finally, the applications of aerosol direct-write for microelectronics are discussed.
