VSParticle NanoPrinter

Easy and controlled printing of nanostructured layers

The VSP-P1 NanoPrinter is the ultimate prototyping and R&D platform for material development and small-scale production testing. Based on impaction deposition of spark ablated material, the system employs additive manufacturing to simplify production of nanoporous thin films and layers with a high surface-to-volume ratio.

Typical applications:

  • High-throughput screening of electrocatalysts
  • Ink-free catalyst coated membrane (CCM) fabrication
  • Multi-layered gas sensor fabrication
  • Surface-enhanced Raman spectroscopy substrate fabrication

Integrated technology: years in the making

By integrating the nanoparticle production source, namely two separate VSP-G1’s, into the tool itself, the whole platform becomes a complete solution for accelerated materials development. This was only possible through numerous years of prototyping and development to yield the commercial version which is available today.

Core Technology

After nanoparticles are produced via spark ablation, the resulting aerosol stream is accelerated through the nozzle using rough vacuum. The driving force for impaction printing onto the substrate is therefore the pressure gradient between the VSP-G1 system and the deposition chamber. Printing of specific patterns is possible through XYZ stage control, a microscope camera module, and an intuitive user interface.

Controlling layer thickness

Different layer thicknesses from sparse agglomerates to continuous layers up to a few microns thick are possible using the VSP-P1. The parameters that impact the layer thickness are:

  • Nozzle distance to substrate
  • Power of ablation
  • Printing speed

Patterning

You can determine the desired printing pattern by running a script through the user interface. Both complex patterns and in-series production of more than one samples are possible using different or modified scripts.

Next generation CCM production

Development of efficient catalyst coated membranes (CCM) is critical for the transition towards green hydrogen economy. The NanoPrinter enables one-step fabrication of CCMs with drastically reduced catalyst loading while maintaining performance and durability.
