Question: Which of the following is the first step of the rapid prototyping process?
A 3D Modeling
B Data Conversion
C Building
D Postprocessing
Answer: 3D Modeling
| Steps of the rapid prototyping process | Description | |
| 1 | CAD Solid Modeling | · Create a digital 3D model of the object using CAD software. |
| 2 | Model Conversion to STL | · Convert the CAD model into an STL (Stereolithography) file format. · The STL file represents the 3D model as a collection of triangles. |
| 3 | STL Model Slicing | · Slice the STL model into thin horizontal layers or cross-sections. · This step is crucial for technologies like 3D printing. |
| 4 | Model Fabrication | · Utilize rapid prototyping technology (e.g., 3D printing) to build the physical prototype layer by layer, following the slicing instructions. |
| 5 | Post-Processing | · After fabrication, the physical prototype may require post-processing. · This can involve removing support structures, surface smoothing and applying finishing touches to achieve the desired appearance and functionality. |
| 6 | Resulting in a Physical Prototype | · The outcome of the rapid prototyping process is a physical prototype, allowing for testing, evaluation and design verification. |
