Using 3D scanning for engineering is the fastest and most cost effective way to make alterations to an existing part or product. The traditional method of taking measurements with a calipers to create a 3D model from scratch is both time consuming, and often inaccurate for items with complex curves and designs.
AccuScan's 3D scanning technology captures huge amounts of cloud point data to an accuracy of 0.05mm. Using specialised software, this data is fused into a high polygon mesh with a resolution of up to 0.1mm. This mesh can be exported in an 3D file format such as obj. or stl., ready for 3D printing, visualisations, and quality control analysis.
3D CAD Conversions
For reverse engineering purposes it is usually desirable to have the high poly mesh converted into a NURBS model format so it can used in a 3D CAD program such as Solidworks. While it is possible to make slight alterations to the polygon mesh without converting it to a nurbs surface, you will be limited to minor fixes. When more accurate or demanding changes have to be made you must convert the mesh.
Converting the polygon mesh model to a NURBS model is a manual process of modelling around the scan to create a clean, solid object with a perfectly smooth surface finish. We use deviation analysis software to ensure that the new solid model is accurate to the original scan. Finished files are manufacture ready and can be used for 3D printing or for technical drawings.
These files can be exported as STEP, IGES, Parasolid and more. We offer this additional file conversion service as an add-on package to having an object 3D scanned.
