Facilitating extraction of three-dimensional object with printed hint

In a digital medium environment for three-dimensional (3D) printing, at least one computer-readable medium storing processor-executable instructions that, responsive to execution by a processing system, cause the processing system to perform operations comprising:

• determining a location at which a 3D object is to be printed in a printer bed of a 3D printer, the determining based at least in part on an object description used to control printing of the 3D object by the 3D printer;
• determining a cross section of the 3D object based on the object description;
• generating a hint indicating the determined location, including generating a description of the hint and a position in the printer bed for printing the hint, the hint having a shape of the cross-section of the 3D object;
• controlling printing of the 3D object in the printer bed by the 3D printer, the controlling based on the object description and the determined location;
• and
• controlling printing of the hint in the printer bed by the 3D printer based on the description and the position of the hint, the printed hint indicative of the determined location of the 3D object in the printer bed.

In a digital medium environment for three-dimensional (3D) printing, a method implemented by at least one computing device, the method comprising:

• determining, by the at least one computing device, a location at which a 3D object is to be printed in a printer bed of a 3D printer, the determining based at least in part on an object description used to control printing of the 3D object by the 3D printer;
• determining, by the at least one computing device, a visual appearance of the 3D object from the object description, the visual appearance including:
• a texture of the 3D object;
• an image of an overall structure of the 3D object;
• an image of particular parts of the 3D object;
• or
• a cross section of the 3D object;
• generating, by the at least one computing device, a hint indicating the determined location and the determined visual appearance;
• and
• controlling, by the at least one computing device, printing of the hint in the printer bed by the 3D printer as having the visual appearance as indicated in 3D relief as part of the hint.
