Researchers develop 3D printed interfaces for enhanced signaling in neurological devices

A team of Chinese and Taiwanese researchers from such institutes as Zhejiang University (ZJU), Taipei Medical University, and National Central University (NCU) have used Aerosol Jet Printing (AJP) to develop 3D nanostructural coatings that enhance signaling in 3D printed neurological devices.

The research paper, published in Advanced Materials explains, “Over the past two decades, prosthetic devices have been successfully applied to treat neurodegenerative disease. However, the long-term utilization is limited by adverse biological reactions in host tissues, resulting in signal failure of the implanted devices.”

“It is more important to design biocompatible coatings for the implanted devices to mimic mechanical and structural properties of brain tissues in order to reduce inevitable tissue responses for long-term utilization.”

Aerosol Jet Printing and neural implants

The AJP process involves spraying metal-based inks onto existing 2D and 3D substrates, creating emulating a multi-layer circuit board interconnections. This method also eliminates the need for complex wire bonding conducted within LED chip fabrication.

Due to its low-temperature technology and contactless nature, the team used AJP to directly fabricate nanogels onto a membrane of the microscaled patterned polyimide-based neural probe. The nanogels were created by the researchers using a “new type of anti-inflammatory nanogel,” based on the amphiphilic polydimethylsiloxane-modified N, O-carboxylic chitosan (PMSC) incorporated with oligo-proanthocyanidin (OPC), called OPMSC.

The OPMSC nanogels were constructed to mimic the structural and mechanical properties of brain tissue and sustain non-fouling (a surface’s ability to shed potential contamination) for tissue encapsulation.

“With the integration of nanomanufacturing technology and multifunctional nanomaterials into the neural implants, we can extensively reduce the reactive tissue responses, provide continuous protection of surviving neurons, and ensure long-term performance reliability of implants,” the researchers explained.

The research paper, titled “Multifunctional 3D Patternable Drug-Embedded Nanocarrier-Based Interfaces to Enhance Signal Recording and Reduce Neuron Degeneration in Neural Implantation,” is co-authored Wei-Chen Huang, Hsin-Yi Lai, Li-Wei Kuo, Chia-Hsin Liao, Po-Hsieh Chang, Ta-Chung Liu, San-Yuan Chen, and You-Yin Chen.

German RepRap introduce first production LAM 3D printer – Technical specifications

German RepRap, manufacturers of FFF 3D printers, has introduced its first Liquid Additive Manufacturing (LAM) production-ready 3D printer, the L280. The company stated:

“LAM is a very interesting 3D printing process because it works with a material that is in a liquid form that is vulcanized under heat exposure to its final form, contrary to the FFF technology.”

“In this way, objects can be produced that have the same properties as injection-molded parts – a clear advantage because insights from the 3D printed prototype can be transferred directly to injection-molded serial parts.”

Liquid Additive Manufacturing

Last year, German RepRap presented the first prototype LAM system at Formnext in Frankfurt, to demonstrate how liquid materials, such as Liquid Silicone Rubber (LSR), can be processed in LAM 3D printers. Differing from FFF hardware, the LAM 3D printer deposited layers of silicone from a syringe whilst using thermal energy to ensure crosslinking.

During this process, the application direction and the vulcanization, a chemical conversion process used in the Digital Light Processing (DLP) at the macromolecular level, can be altered. As a result, parts can be made stronger when compared to injection molding.

The L280 3D printer

The L280 provides a heated print bed and high-temperature halogen lamp to enable optimal cross-linking during the LAM process for durable parts. In addition, the printer features a pressure chamber of  280 x 280 x 200mm (X x Y x Z) and network connectivity. The L280 also includes safety technology which monitors the curing process and immediately stops the process according to irregularities.

Moreover, a maintenance contract and a professional on-site service are available as an option from trained technicians using the L280. According to German RepRap, the L280 3D printer has “proven its reliability in continuous operation in extensive tests and pilot applications in practice.”
