The legacy can be any component that has passed the glory days, so it is no longer new. Over the years, these parts have been difficult to replace and have forced owners to spend thousands of dollars on new machines.
Fortunately, due to advances in 3D manufacturing technology, it has become easier to re-create these components; here are a few ways to create old parts to make CAD files:
High resolution 3D scanning:
High-resolution 3D scanning is the easiest way to create digital 3D CAD files of physical real-world objects. 3D scanning produces a highly detailed, accurate 3D mesh at a relatively economical price, making it ideal for product applications that require precise fit and functionality.
In some cases, the grid can be printed as is; otherwise, 3D Designer can optimize the file to make it ready for 3D printing. The range of optimization can range from touching the model (closing small gaps, rounded corners, hollowing out holes that the scanner may miss, etc.) to reversing the grid into solid parametric CAD files. The degree of file repair required depends on the complexity of the component and the expected functionality.
Although 3D scanning is not suitable for every project, it is ideal for projects that require precise duplication, as well as projects that may be difficult to solve by manual reverse engineering.
View the part and recreate the part. Reverse engineering is the process of creating a technical drawing of a part by a trained designer or engineer and then generating a 3D CAD file.
This CAD file creation method requires a complete existing part that can be measured using the available tools. Dimensioning dimensions, the designer will recreate the part within the necessary tolerances. The end result is a dimensional drawing of the 3D CAD files and parts that can be manufactured.
Reverse engineering is best suited for smaller mechanical components such as gears, brackets and housings. All reverse engineering requires physical access to the part; whether to ship parts that are measured or measured on site.
Creating a CAD file from a dimension drawing is very simple. This is much like reverse engineering, but all measurements are documented.
If the customer needs a 3D CAD file and already has a dimensional drawing or DWG file, the designer will simply draw the 3D CAD version of the drawing based on these dimensions.
