Appl. No.:

16/833540

Inventors:

Karl Joseph Dodds Gifford - Norcross GA, US
Tue Nguyen - Fremont CA, US

International Classification:

B29C 64/245
B29C 64/295
B29C 64/209
B29C 64/241
B29C 64/232

Abstract:

A rotatable and shrinkable platform for a 3d printer system can include multiple segments disposed next to each other around the axis of rotation. The segments can move between a printing configuration and a shrunk configuration. In the printing configuration, the segments are continuously and smoothly disposed next to each other to present a printing surface suitable for printing. In the shrunk configuration, the segments are overlapped to break the adhesion of a printed object with the platform to facilitate the removal of the printed object from the platform.

Abstract:

A modular 3D printer system can include a base subsystem and multiple exchangeable components. The base subsystem can have a 3D motion module, a printhead module and a platform module. The multiple exchangeable components can include printheads having different configurations and functionalities, which can be exchangeably installed in the printhead module. The multiple exchangeable components can include platform supports having different configurations and functionalities, which can be exchangeably installed in the platform module.

Appl. No.:

15/291038

Inventors:

Karl Joseph Gifford - Norcross GA, US
Tai Dung Nguyen - Fremont CA, US
Tue Nguyen - Fremont CA, US

International Classification:

B29C 67/00
A61M 5/31
A61M 5/315
B33Y 30/00

Abstract:

The coupling between the plunger and the piston can be removable. The removal of the plunger can form a split syringe, which can be used for ease of transport. The split syringe can be mounted on a print head for printing using a 3D printer.

B33Y 50/02
B33Y 10/00

Abstract:

A print head comprising two shafts disposed in opposite sides of a filament to drive the filament to a heated chamber for delivering a molten material. The shafts are actively driven, for example, by two independent motors. The two shaft configuration of the print head can improve a control of the filament movement rate, especially for soft filament materials.
