Final answer:
Janice should use the STL file format to compress her animation for 3D printing, as formats like JPEG, PNG, and GIF do not contain necessary dimensional data for 3D printing. Option c is the correct answer.
Step-by-step explanation:
When it comes to 3D printing, the file format plays a critical role in the outcome of the printed object. For Janice to print her animation with a 3D printer, she must use a file format compatible with the printer, which can convert her design into a tangible 3D object. The file formats like JPEG, PNG, and GIF are primarily used for storing raster graphics and are not suitable for 3D printing processes. These formats lack the dimensional data needed for a 3D object.
On the other hand, STL (Stereolithography) is the correct option for this purpose. The STL format is widely used in 3D printing as it contains all the necessary information for a 3D printer to construct the object, such as the geometry and layout of the finished design. It breaks down the surface of a 3D model into triangles, allowing the printer to interpret the shape and dimensions accurately. For Janice, using an STL file will allow the 3D printer to comprehend the design accurately, thereby ensuring a better-printed result.
Therefore, the correct option for compressing Janice's animation for 3D printing is c. STL. This file format will maintain the integrity of her design and ensure that her animation is accurately represented in its printed form.
