The present disclosure relates to a system for optimizing an additive manufacturing (AM) process. The system may use a printing component for using a material to form a component in a layer-by-layer process. An electronic controller may control movement of one of the printing component or a substrate on which the component is being formed, in a manner to optimize a toolpath for the printing component as each layer of the component is formed. Optimization operations are performed using an optimization subsystem which enables manufacturability constraints, as well as optimized toolpaths for each layer of the component, to be defined using contours of a level-set function. The level-set function may be used to define the optimized toolpaths within a fixed, predetermined grid, and the optimized toolpaths then used to generate suitable code for controlling movement of the printing component relative to the substrate to create the part or structure in a layer-by-layer process, using the optimized toolpaths.

Optimal toolpath generation system and method for additively manufactured composite materials

The invention provides a metallopolymer coordination network comprising one or more coinage or similar metals and a glyme or glyme-equivalent. The composition has an amorphous polymer network that is significantly stronger than previously reported supramolecular hydrogels synthesized without glyme. Glyme chain length and water content strongly influence the mechanical, electronic, and optical behavior of the network.

Reversible metallopolymer network

The invention provides novel gold nanoclusters of the formula Au(SR)(weak ligand), wherein each R is independently an organic group, and the weak ligand is a weakly associating gold ligand of Formula I as described herein. The nanocluster can have an approximate molecular weight of 6 kDa. Corresponding dimers of the nanocluster can have an approximate molecular weight of 10 kDa (by SEC). The invention also provides methods of making and using the gold nanoclusters.
