SAT Question b07a7634: Answer & Explanation

While researching a topic, a student has taken the following notes:

• Digital Light Synthesis (DLS) is a form of additive manufacturing that utilizes light to rapidly cure liquid resin into high-quality, 3D objects.
• Step 1: Ultraviolet (UV) light images are projected up into a pool of liquid resin, where the object’s first layer takes shape.
• Step 2: The partially cured resin object is raised, leaving a thin space (a “dead zone”) beneath it for oxygen and liquid resin to flow through.
• Step 3: The UV light passes through the dead zone—maintaining the flow of resin—and partially cures additional layers of the object.
• Step 4: When the resin object is complete, it is baked in an oven to complete the curing.

The student wants to describe how DLS cures 3D objects. Which choice most effectively uses relevant information from the notes to accomplish this goal?

DLS is a form of additive manufacturing that creates a “dead zone” in which UV light solidifies layer by layer before being baked in an oven, creating a high-quality, 3D object.

DLS cures 3D objects by passing through a “dead zone,” adding layers to the object, then curing the object in an oven.

In DLS, UV light images are projected into a liquid resin pool to cure a 3D object layer by layer; once solidified, the object is baked in an oven.

In DLS, UV light is projected into layers of liquid resin until the resin solidifies and passes through a “dead zone,” wherein the curing is completed.
