POLYMER COMPOSITES FOR FUSED FILAMENT FABRICATION AND METHODS OF MAKING THE SAME

Patent ID: 9461 | Patent Number 10,744,695 | Status: Granted

Abstract

Material formulation for additive manufacturing (AM) will be central to the progression of the industry as it moves from novelty to a mainstream, disruptive technology. We disclose in the document methods and techniques of formulating highly porous specially engineered materials for use in fused deposition modeling printers, achieving high loadings of several species of Metal Organic Frameworks (MOFs) combined with a sacrificial fluoropolymer process that enables the retention of the parent MOF chemical characteristics. We have achieved loadings up to 50% with MOFs while still retaining the ability to print the material on a standard FDM machine. Through a sacrificial process, we show that surface areas up to 712 square meters per gram of printed material can be achieved. We have further demonstrated that high loadings are required to attain the functionality of the parent MOF characteristics, and have defined the lower threshold for viability of this loading.
