Abstract
A three-dimensional printing apparatus includes a material receiving area for receiving material, a plasticizer, a discharge pump and an auger. The material receiving area receives material to be used to be used in the three-dimensional printing process. The plasticizer includes a heating zone which places the material in shear. The discharge pump controls the flow of the material. The auger extends from the material receiving area through the plasticizer and terminates proximate the discharge pump. The material is maintained under pressure in the discharge pump until the material exits a nozzle provided at the end of the discharge pump for depositing on a build plate.
Claims21
A three-dimensional printing apparatus comprising;
- a material receiving area for receiving material to be used in the three-dimensional printing process;
- a plasticizer having a heating zone, the plasticizer places the material in shear;
- a discharge pump which controls the flow of the material;
- an auger which extends from the material receiving area through the plasticizer and terminates proximate the discharge pump;
- wherein the material is maintained under pressure in the discharge pump until the material exits a nozzle provided at the end of the discharge pump for depositing on a build plate.
A three-dimensional printing apparatus comprising;
- a material receiving area for receiving material to be used in the three-dimensional printing process;
- a plasticizer having a heating zone, the plasticizer having a first auger which extends therethrough from the material receiving area and terminates proximate a discharge pump;
- the discharge pump having a second auger, the second auger moves the material from the first auger to a nozzle, the second auger is in line with and cooperates with the first auger to control the flow of the material, thereby maintaining the material under pressure until the material exits the nozzle.
A three-dimensional printing apparatus comprising;
- a material receiving area for receiving material to be used in the three-dimensional printing process;
- a plasticizer having a heating zone and an unheated or cooled zone, the plasticizer places the material in shear, the heating zones cooperate with material to melt the material;
- a discharge pump which controls the flow of the material;
- wherein if the flow of material through the plasticizer and discharge pump is stopped or slowed, the unheated or cooled zone will solidify the melted material, preventing the backward flow of melted material.
A three-dimensional printing apparatus comprising;
- a material receiving area for receiving material to be used in the three-dimensional printing process;
- a plasticizer which places the material in shear;
- a discharge pump which controls the flow of the material;
- a first auger which extends from the material receiving area through the plasticizer and terminates proximate the discharge pump;
- a second auger is provided in the discharge pump
- wherein the second auger cooperates with the first auger to maintain the material under pressure until the material exits the nozzle.
