3D printing rapid prototyping is a process that involves the creation of a physical object from a 3D computer model by building it layer by layer. Some of the key process characteristics of 3D printing rapid prototyping include:

1. Layer-by-layer fabrication: 3D printing rapid prototyping creates objects by adding material layer by layer, which is known as additive manufacturing. This allows for highly precise and complex geometries to be produced.

2. Computer-aided design (CAD): The process begins with the creation of a 3D computer model using CAD software. The software slices the model into layers and generates instructions for the printer to build the object.

3. Material selection: Different 3D printing technologies use different materials, such as plastics, metals, ceramics, or even food. The choice of material depends on the requirements of the object being printed.

4. Printing speed: The printing speed can vary depending on the complexity of the object and the printing technology used. However, 3D printing rapid prototyping is generally faster than traditional manufacturing methods for creating prototypes.

5. Post-processing: Once the object is printed, post-processing steps such as polishing, painting, or sanding may be necessary to achieve the desired finish.

6. Cost-effectiveness: 3D printing rapid prototyping can be a cost-effective way to produce prototypes since it eliminates the need for expensive tooling and can reduce the time and cost of design iterations.

7. Customization: 3D printing rapid prototyping allows for easy customization of objects since each layer can be individually designed and produced. This makes it ideal for creating one-of-a-kind objects or small production runs.
