An Algorithm solution for the computation of nonplanar continuous interweaving 3D Printing tool path for polymers and polymer composite material

Summary of the technology

An implemented algorithmic solution for the generation of continuous interweaving algorithms toolpath for additive manufacturing of medium to large parts using stable polymer matrices

University of Alberta, Technology Transfer Services

Details of the Technology Offer

The University of Alberta researchers have developed an algorithm for a 3D printing toolpath. The project is intended to develop a solution capable of manufacturing carbon fiber parts using additive manufacturing while conserving the structural and mechanical properties of commonly manufactured parts. This project implements a non-planar continuous interweaving toolpath for medium to large-volume parts with similar properties to those observed with common composite matrix part production. The map encodes the vertical motion of the nozzle according to the average height of material deposited in its close neighborhood to avoid any collision between the nozzle and the previously deposited matrix.
