High resolution, high throughput additive manufacturing

A system for high-resolution three-dimensional (3D) printing, the system comprising:

• a photo-thermal curing subsystem comprising a first laser source coupled to an optical fiber positioned to deliver a first laser light to a scanning optical device;
• an optical projection subsystem comprising a second light source configured to provide a second light to a digital projection device;
• a dichroic mirror positioned to receive light corresponding to the first laser source from the scanning optical device and to receive light corresponding to the second light source from the projection device;
• and
• an objective lens positioned to provide illumination to a target material for 3D printing, wherein:
• the dichroic mirror is configured to allow one of the light corresponding to the first laser source or the light corresponding to the second light source to pass therethrough to the objective lens, and to allow the other of the light corresponding to the first laser source or the light corresponding to the second light source to be reflected towards the objective lens, and
• wherein the objective lens allows simultaneous illumination of the target material with both the light corresponding to the first laser source and the second light source.

A system for high-resolution three-dimensional (3D) printing, the system comprising:

• a first light source configured to produce a laser output in an infrared (IR) region,
• a second light source configured to produce a laser output outside of an IR region, both the first and the second light sources configured to provide illumination to an optical scanning device to allow 3D printing based on two-photon polymerization (TPP);
• a third light source configured to provide illumination to a first digital projection device, the third light source configured to produce an output in an IR region,
• a fourth light source configured to provide illumination to a second digital projection device, the fourth light source configured to produce an output in an ultraviolet (UV) region;
• and
• an objective lens positioned to receive light corresponding to the first through the fourth light sources and to provide illumination for 3D printing, wherein:
• the objective lens allows simultaneous illumination of a target area designated for placement of one or more target material with light corresponding to the first, the second, the third or the fourth light sources.

A method for three-dimensional (3D) printing a component that includes multiple materials, the method comprising:

• pouring, placing or positioning a first material in the area designated for placement of a target;
• using a 3D printing system to print a first part of the component;
• pouring, placing or positioning a second material in the area designated for placement of the target such that at least a portion of the second material is situated between the printed first part of the component and the objective;
• and
• using the 3D printing system to print a second part of the component.

A method of three-dimensional (3D) printing a component, comprising:

• using a subsection of a 3D printing system to print a first section of the component using two-photon polymerization (TPP);
• and
• using another subsection of the 3D printing system to print a second section of the component based on illumination provided by one or more projection devices, wherein:
• the first section of the component has a higher print resolution than the second section of the component, and
• printing of the first section and the second section of the component are carried out simultaneously.
