This paper introduces and investigates NiChrome wire sintering, a novel fabrication technique in the field of additive manufacturing. With a combination of differentiated material states and material properties, this research generates forms with different sintering strategies through computation and fabrication systems. Rather than creating objects through selectively depositing melted material in a predetermined path, layer-by-layer, this rapid prototyping methodology generates 2D or 3D spatial wireframes by weaving NiChrome wire and sintering thermoplastic polyurethane (TPU) onto it by utilizing the instantaneous high temperature of NiChrome wire after electrification. A series of experiments is presented utilizing a proportional integral derivative (PID) temperature control system in cooperation with thermal camera equipment to ensure consistent results under the same conditions. In addition, the project focuses not only on developing NiChrome wire sintering systems but also on the applicabilities of this technique by fabricating wireframe surfaces under different situations.
