Abstract
A method and apparatus for additive manufacturing that includes a material guide for directing a supply of working material. An advancement mechanism comprising one or more pistons, pushers, plungers and/or pressure regulation systems are positioned behind at least a portion of the supply of working material for advancing the working material forward. The working material is heated using an electro-magnetic heating element and the melted or molten working material is deposited from a tip positioned at an end of the material guide.
Claims21
A printing nozzle for use in deposition for additive manufacturing comprising:
- an advancement mechanism for advancing a working material forward during operation;
- a primary material guide for permitting a desired flow of the working material;
- a secondary material guide positioned in parallel with the primary material guide;
- a gate positioned between the secondary material guide and the primary material guide, the gate selectable to alternatively close off at least one of the secondary material guide and the primary material guide;
- a tip positioned at an end of the material guides for depositing the working material in an appropriate position in space;
- and
- an electro-magnetic heating element positioned with respect to the primary material guide.
