Aerosol Jet 5X

General Introduction

The Aerosol Jet 5X is a multi‑axis, high‑precision aerosol jet printing system designed for industrial‑grade electronic 3D printing and high‑end research prototyping. It combines exceptional process flexibility, material compatibility, and print accuracy, making it ideal for fabricating electronic components across diverse sectors, including consumer electronics, aerospace, semiconductors, and medical devices. Built on aerodynamic focusing technology and featuring five‑axis motion control, the AJ 5X enables non‑contact, high‑precision printing on planar, curved, and complex 3D substrates, overcoming the traditional limitations of conventional electronics manufacturing in terms of substrate shape and size. The AJ 5X accommodates a broad range of viscosities, from low‑viscosity conductive inks as low as 1 cP to high‑viscosity pastes up to 1,000 cP, with stable processing capabilities. It supports a wide array of functional materials—conductive, resistive, dielectric, and more—enabling direct fabrication of electronic structures ranging from fine 10‑micron traces to large‑area coatings spanning millimeters. Integrated modules for in‑situ sintering and curing, along with a high‑precision vision alignment system, enable seamless “print–cure–form” integrated processing. Additionally, the system features a 300 × 300 mm heated vacuum platform, ensuring optimal processing conditions for various substrates. The AJ 5X has been adopted by leading global companies and research institutions, such as Samsung and Northrop Grumman, establishing itself as a core tool for 3D electronics manufacturing, device prototyping, and small‑batch production. While maintaining industrial‑grade reliability, the AJ 5X also prioritizes ease of use, supporting offline CAD/CAM programming that allows rapid translation of design concepts into physical products, thereby significantly shortening the R&D and production cycles for electronic components.

Working principle

The Aerosol Jet 5X is built around aerosol jet printing (AJP) technology, with its entire workflow organized around five core stages: atomization, aerosol transport, aerodynamic focusing, precise deposition, and in‑situ post‑processing. The process is entirely non‑contact, ensuring the integrity of both the substrate and the printed structure. First, the system atomizes liquid printing materials using either ultrasonic or pneumatic atomization. Ultrasonic atomization is suited for low‑ to medium‑viscosity materials ranging from 1 to 10 cP, employing ultrasonic vibrations to break the material into uniform droplets approximately 15 µm in diameter. Pneumatic atomization accommodates a broader viscosity range, from 1 to 1000 cP, using high‑pressure gas to generate aerosol droplets; these two methods can be flexibly switched based on material properties. Next, an inert carrier gas transports the atomized aerosol droplets to the print head, where droplet selection takes place during transit—excessively large or small droplets are removed to ensure aerosol uniformity, laying the groundwork for high‑precision printing. Subsequently, an annular protective gas flow within the print head creates an aerodynamic focusing stream, compressing the aerosol droplet beam into a narrow, high‑velocity jet capable of reaching speeds up to 100 m/s. This jet maintains focus even at standoff distances exceeding 3 mm, enabling non‑contact conformal deposition that meets the demands of complex 3D substrates. Following this, the system’s five‑axis motion control drives either the print head or the substrate along pre‑programmed CAD paths, precisely depositing the aerosol jet at the target location and building up the desired electronic circuits or structures layer by layer. During deposition, a vacuum platform secures the substrate, while a heating function allows temperature adjustment to enhance interlayer adhesion and overall build quality. Finally, the integrated continuous infrared laser performs in‑situ sintering of metallic conductive inks, and UV lamps enable in‑situ curing of photosensitive materials—eliminating the need for secondary processing and completing the formation of electronic structures directly, thereby ensuring both processing efficiency and consistent structural performance.

Advantages and Key Features

The Aerosol Jet 5X’s core advantages lie in its multi‑axis machining flexibility, broad material compatibility, and high‑precision non‑contact printing, while also offering integrated processing capabilities and industrial‑grade stability—key differentiators from conventional electronic manufacturing equipment. In terms of motion control and machining flexibility, the system supports five‑axis simultaneous motion, enabling printing at arbitrary spatial angles and overcoming the limitations of traditional 2D printing. It can fabricate conformal electronic circuits on curved surfaces, complex geometries, and 3D substrates, meeting the needs of non‑planar electronics such as aerospace‑grade custom components and wearable medical devices. Additionally, the device features an adjustable lift‑off distance of 1–5 mm, eliminating the need for close contact with the substrate and thereby preventing scratches or damage to delicate materials. Regarding material compatibility, the system accommodates viscosities ranging from 1 to 1000 cP, covering conductive nanometal inks (silver, copper, gold), dielectric pastes, resistive materials, polymers, and even bio‑materials. It can directly print conductive traces, embedded resistors, dielectric layers, sensors, and other functional electronic structures without requiring replacement of specialized print heads, significantly enhancing versatility and reducing material‑change downtime. In terms of printing accuracy and quality, the system achieves a resolution of up to 10 µm, with exceptional motion‑control precision. Coupled with a high‑accuracy vision‑based alignment system—including Blob, Edge, and PatMax tools—it enables micron‑level deposition, with line width and pitch that can be finely tuned to meet the demands of intricate electronic structures. Moreover, its non‑contact printing approach eliminates physical contact between the substrate and the print head, minimizing defects and boosting yield. Furthermore, the device integrates on‑site sintering and curing modules, enabling seamless integration of printing and post‑processing steps and obviating the need for separate sintering and curing stages in conventional workflows, thus shortening cycle times. A 300 × 300 mm heated vacuum platform provides stable substrate fixation and precise temperature control, with heating temperatures tailored to accommodate most electronic materials and compatible with a wide range of substrates, including metals, ceramics, plastics, and flexible polymers. In terms of operation and production efficiency, the system supports offline CAD/CAM programming, allowing rapid conversion of design files into print paths, and is equipped with a digital recipe‑control system for precise adjustment and storage of printing parameters, ensuring consistent batch‑to‑batch performance. Its compact, industrial‑grade design meets the demands of extended continuous operation, making it suitable for both research prototyping and small‑batch industrial production. Compared with traditional screen printing and inkjet printing, the AJ 5X eliminates the need to fabricate dedicated screens or molds, enabling mold‑free fabrication and substantially reducing production costs for small‑run, customized products, while delivering superior printing accuracy and material compatibility.
