Abstract
A method and apparatus for additive manufacturing that includes a material guide for directing a supply of working material. An electro-magnetic heater is provided to heat and deposit molten working material as a new supply of working material is forced through the material guide. A single or twin screw extruder is provided within for advancing, mixing and/or depositing the working material through a tip positioned at an end of the material guide.
Claims15
A printing nozzle for use in deposition for additive manufacturing comprising:
- an extruder for advancing a working material forward during operation;
- a material guide for permitting a desired flow of the working material;
- a tip positioned at an end of the material guide for depositing the working material in an appropriate position in space;
- and
- an electro-magnetic heating element positioned with respect to the material guide.
A printing nozzle for use in deposition for additive manufacturing comprising:
- an extruder for advancing a working material forward during operation;
- a material guide for permitting a desired flow of the working material;
- a hopper in fluid communication with the material guide, the hopper for providing a supply of filler material to the material guide during operation;
- an electro-magnetic heating element positioned with respect to the material guide;
- and
- a tip positioned at an end of the material guide for depositing a molten build material resulting from the working material and the filler material in an appropriate position in space.
A method of additive manufacturing comprising:
- providing a supply of a working material;
