Description

ABSTRACT:Lynntech proposes one of a kind Hybrid Additive Manufacturing Machine with Error Rectification (HAMMER), which is exclusively designed to 3D print different material classes (plastics, metals, and ceramics). To efficiently manufacture parts with minimal waste, HAMMER will be equipped with optical precision alignment and feedback control system. Current multimaterial Additive Manufacturing machines are capable of processing only one type of material (e.g. liquid photopolymers). While it allows for creation of functionally graded objects that contain plastic-like and rubber-like sections, it does not permit fabrication of truly hybrid parts. Fabrication of hybrid materials where different classes of materials deposited simultaneously will allow parts to be produced with properties tailored by location. Hybridization and shape complexity promises to significantly improve functionality of manufactured components, reduce their weight, and cut down cost of manufacturing. Lynntechs technology promises fabrication of hybrid 3D components with polymeric, metallic, and ceramic sections. Furthermore, HAMMER will have a capability of self-alignment thus providing geometrically accurate prints. This unique technology will be faster, more power efficient, and less expensive than selective laser sintering or electron beam technologies. BENEFIT:The HAMMER will enable production of hybrid objects by using polymers, metals, and ceramics simultaneously. This will lead to more efficient manufacturing of structural components for military purposes, reducing their weight and improving functionality. Moreover, Lynntechs technology will allow for more efficient component production, thus reducing amount of base materials used and decreasing manufacturing costs. In addition to military markets, Lynntechs HAMMER is highly applicable to commercial sectors including advanced parts manufacturing in aerospace, automobile, medical, and education sectors.
