Portfolio 5: Materials, manufacturing and applications

fdThe research

The aim of Portfolio 5 is that by 2025 New Zealand will be selling new customised products, equipment and materials based on New Zealand’s biological resources and distributed manufacturing; and new companies are fuelling the growing global green sector.

We see a big opportunity for New Zealand in the application of biopolymers – natural products, to create new engineered products such as new plastic-like materials suitable for 3D printing into engineering components and furniture.

While New Zealand has significant scientific capability in this area, we recognise the science must be driven by commercial opportunities, with a tight focus on the areas in which New Zealand firms already have, or can build, a competitive edge.

Not only will there be applications for industries where New Zealand has already demonstrated market share such as aerospace and marine products, farming equipment and medical devices, but also in established industries with aspirations to diversify into new product lines for export.

The research will therefore be underpinned by materials and process modelling, materials science and design and engineering. It will predict the behaviour of the engineered biopolymers and biopolymer composites and the design required for the appropriate equipment to process new materials. 

bjiAdditive manufacturing and 3D and/or 4D printing of bio-composites

sdThe spearhead project for Portfolio 5 is additive manufacturing and 3D printing of bio-composites. It has four main areas of focus:

  • engineering lignin and protein biopolymers alone and in combination for processing by additive manufacturing
  • engineering molecular interactions to improve properties when made by additive manufacturing
  • engineering cellulose, lignin and protein nano/micro fibres for low shear interactions and aligning and layering
  • new additive manufacturing equipment for biopolymers to enable larger-scale processing and gradient structures.

Potential application areas include furniture, appliances, electronics, sensors, marine components, aerospace components, agritech and medical devices.

In the first year, the project team will consult with industry and the science community to confirm the specific application area for bio-based additive manufacturing that the spearhead will address in its research programme.
