Provisional Patent Application Filed

In 3D printing, the currently used microcrystalline cellulose (MCC) and cellulose nanocrystals (CNC) have much lower molecular weights and lower degrees of polymerization than raw cotton-based cellulose, which is why they are much easier to dissolve. This technology provides a potentially novel method to produce raw cotton cellulose based conductive materials with the use of (1) a specific freeze-drying pretreatment methodology to increase viscosity and allow homogeneity to meet 3D printing cellulose standards and (2) a 3D printing layer-by-layer technique to incorporate conductive properties. 

Reference Number: D-1166 

Market Applications:

  • 3D printing, electrical engineering, consumer products
  • Further, this method has the potential for use in photovoltaic applications such as solar cells, conductive material for biological signal delivery, and as electrical paper and conductive fabric. 

Features, Benefits, and Advantages:

  • Potentially increasing the current market for raw cotton because of the use of cotton derived cellulose.
  • Increases in 3D printing efficacy
  • Decrease in cost and material 

Intellectual Property:

A U.S. Provisional Patent application will be filed in the near future. 

Development Stage:

This technology has completed testing and there are no current sources of funding for the research. The next objectives are to replicate real market place products.
