Product Introduction
Aconity MICRO Micro- and Nano-Scale Metal 3D Printer
General Introduction
The Aconity MICRO is a compact, non‑configurable laser powder bed fusion (LPBF) metal 3D printer launched by the German company Aconity3D. Designed specifically for micro‑ and nano‑scale additive manufacturing, it serves as the brand’s flagship entry‑level solution for precision microstructure fabrication. Featuring a plug‑and‑play assembly design, it operates on a 380 V three‑phase power supply, with power consumption compliant with laboratory‑equipment standards. This system focuses on the practical implementation of micro‑LPBF technology, integrating Aconity’s proprietary vibratory powder‑dispensing technique to achieve uniform powder spreading even with ultra‑fine metal powders, thereby meeting the forming requirements of microscale functional components. Its fully retractable powder hopper and build tray significantly reduce material‑change times, while its WebSocket‑based remote‑access capability enables rapid initiation of print jobs. The Aconity MICRO is well suited not only for micro‑ and nanofabrication research in academic institutions but also for small‑batch prototyping of precision micro‑components in industrial settings. As a dedicated platform for micro‑ and nano‑scale metal additive manufacturing, it balances compactness with professional‑grade performance, eschewing unnecessary features and precisely addressing the core needs of microfabrication.
Working principle
Aconity MICRO employs micro‑ and nano‑scale laser powder bed fusion as its core technology, with the entire process following a discrete‑additive manufacturing paradigm and undergoing comprehensive technical optimization for microscale fabrication. Upon startup, users first design the microstructural part model using 3D CAD software; the model is then sliced into micron‑level layer data by slicing software. After importing this data into the Aconity Studio control software, the system enters automatic operation mode. The device’s vibratory powder‑dispensing system evenly spreads ultrafine metal powder—matched to an appropriate particle size—with layer thicknesses below 10 μm onto the build platform. Once powder spreading is complete, the fiber laser emits a beam that, after being focused by a high‑precision optical system into a 40‑μm spot, selectively scans the powder bed according to the layer data. The laser energy is absorbed by the metal powder, rapidly raising its temperature above the melting point and inducing localized melting and fusion. Following each scan, the build platform advances downward by a microscopic step of 5 μm, completing one layer. The powder‑spreading mechanism then re‑applies powder, and the laser continues selective melting, repeating the cycle of layered melting and solidification until the entire microstructural part is fully built. Upon completion, the system recovers excess powder via a removable powder hopper, and the finished part undergoes post‑processing to yield the final product. Throughout the process, Aconity Studio continuously monitors key parameters such as laser power, scanning speed, and powder‑spreading accuracy, ensuring stable microscale fabrication.
Advantages and Key Features
Aconity MICRO’s advantages lie in three key areas: micro‑ and nano‑scale forming accuracy, specialized design, and ease of operation, while also featuring technical characteristics tailored to microfabrication applications. Paired with vibratory powder deposition technology, the system can fabricate honeycomb‑ and lattice‑structured microfeatures with wall thicknesses as low as 40 μm, meeting the precision requirements of micro‑ and nanomanufacturing. In terms of design, it employs a non‑configurable architecture with no superfluous functional modules, resulting in a compact footprint and low power consumption that aligns with typical laboratory space and power‑supply constraints. Additionally, its fully removable powder cartridge and build tray enable material changes without disassembly, significantly boosting the efficiency of multi‑material prototyping in microfabrication workflows. On the operational side, the device integrates Aconity Studio web‑based control software, supporting WebSocket‑based remote access, import/export of print jobs, and independent adjustment of all process parameters. Operators can monitor the printing process remotely, eliminating the need for on‑site supervision. Furthermore, the system is compatible with mainstream slicing tools such as Autodesk Netfabb and Materialise Magics, offering robust file‑format support, and adopts a plug‑and‑play design that allows for rapid assembly and commissioning right out of the box, thereby lowering the barrier to entry for micro‑ and nanoscale 3D printing. At the same time, the equipment boasts high powder utilization; microscale printing requires only minimal metal powder to complete prototypes, effectively containing material costs in both research and small‑batch production settings.
Application Areas and Use Cases
Leveraging its micro‑ and nano‑scale additive manufacturing capabilities, Aconity MICRO is primarily deployed across four key domains: precision medical devices, microelectromechanical systems (MEMS), aerospace micro‑components, and the prototyping of research‑grade microstructures. It serves core R&D and small‑batch production scenarios that demand stringent part‑size and precision requirements, with well‑established application cases in each field. In the precision medical device sector, the system can fabricate miniature medical implants, such as ophthalmic micro‑stents and cardiovascular micro‑filters. For instance, it was used to produce a titanium‑alloy ophthalmic micro‑stent for a German medical‑device company; the stent wall thickness is only 50 μm, with forming accuracy meeting the medical standards for human implantation, while laser‑melting technology ensures both structural strength and biocompatibility. In the MEMS domain, it enables the fabrication of metal micro‑electrodes and critical sensor components. A European microelectronics research institute employed this equipment to produce copper‑alloy micro‑electrodes, achieving dimensional tolerances within ±2 μm—fully compliant with the assembly requirements of MEMS devices. In aerospace micro‑component manufacturing, it supports the prototyping of miniature metal parts for satellites and drones, such as micro‑drive gears and micro‑heat‑dissipation channels. One aerospace research institution utilized the system to print titanium‑alloy micro‑heat‑dissipation channels, delivering highly efficient thermal conduction at the microscale and addressing the lightweighting and miniaturization needs of space‑borne systems. Finally, in the realm of research‑oriented microstructure prototyping, the platform is ideally suited for universities conducting studies in micro‑ and nano‑additive manufacturing, including mechanical property testing of metallic micro‑lattices and investigations into the melting behavior of ultrafine powders. Its precise control over process parameters provides a reliable experimental platform for scientific research.
