What is 3D Scanning? 3d scanning is a technology used to collect a 3d data set of an object or part. 3D scanning companies use the digitization process to capture the exact size and shape of a part without need for cutting or destruction. The data is then used to construct a 3d model. Surface variations can be analyzed with user-definable color patterns. Cross sections give the ability to see otherwise hidden features. Materials of different densities and surface finishes are a good fit for 3d scanning as well. There are a variety of technologies used to acquire x, y, and z coordinates of a real-world object. Some 3D scanning companies don't invest in suitable or precision equipment. If you choose to work with Nel PreTech, you’ll find we employ metrology-grade 3d scanning technologies.

Each have their own benefits and applications. 3D Scanning Output Options Getting to know the customer, the part, and intended use of the 3d scan data we provide helps us determine the best delivery method for your objectives. 4 Key Outputs: 1. Raw data: A cloud of points. Sometimes a company may want this data for archival purposes or to test a tool over time to see if there is any wear. 2. STL file: Polygon mesh 3. Surface Wrap: Exact and true representation of the part “as is” in a.step file. 4. Parametric Model: Builds perfect surfaces on top of an imperfect part or scan data. FAQ: 3D Scanning & Reverse Engineering We can provide scanned data as-is in an STL format. Models that are reverse engineered can be provided in a STEP, IGES, or Parasolid format. In some cases, we can also provide files in a native SolidWorks format. However, this is determined on a case-by-case basis. Dimensional accuracy depends on the method used to capture the data. Each measurement tool has its own accuracy. Generally speaking, our CMM’s provide data that is accurate to ± 15 µm. Our structured light scanner provides an accuracy of ± 16 µm for parts up to 300 mm. For parts that are 300 - 900 mm, our structured light accuracy is ± 37 µm. For items CT scanned in our Zeiss Metrotom 800, our accuracy is ± 9.7 µm. For items CT scanned in our Zeiss Metrotom 1500, our accuracy is ± 11 µm. For items that are reverse-engineered and modeled using our scan data as a template, the results can be somewhat variable depending on the material of the original part and the condition of the original surfaces that we are interpolating. Typically, models that are created from steel parts usually have a surface accuracy of ±.001” or less to the original scanned surface. The accuracy of models that are produced from plastic injection molding usually has a surface accuracy of ±.001” to.005”. For large parts like auto body panels or bumpers, the surface deviation of the final model may be much larger, depending on part condition and customer needs. Yes. We have the ability to provide accurate external geometry for items like these. Yes. However, it is easiest to provide scan data on these types of objects if they can be brought in or sent to our laboratory. Our ability to blue light scan on location is somewhat limited due to our current restriction of scanning objects up to a maximum of 4 feet. Yes, we can provide CAD drawings in a 2D DXF format. We can usually quote most items from detailed photographs that have a size reference with them. For specialized parts like manifolds or assemblies, we may require that the parts be sent to us for evaluation prior to quoting the project. 3D files or drawings are also helpful if they are available. The more information, the better. An STL file is already sufficient to 3D print parts. If the customer requires a custom CAD model be produced from parts that have already been scanned by a 3rd party, we have the ability to do so. However, we cannot guarantee the accuracy of the original scan method.
