3D Scanning

Anything but superficial

The 3D scan is a non-contact, high-precision geometric 3D acquisition.

Here we differentiate according to the size of the object to be measured and the purpose of use. Individual components up to a size of approx. 1m³ can be precisely measured with high-precision, optical and tactical 3D scan measuring instruments. We can carry out the measurements both in our measuring laboratory and at the customer's site.

Benefits for Area measurement of components

In order to "secure" the quality, we carry out an investigation between your real product and the CAD reference object.

The 3D scan is aligned according to your specifications (e.g. via references, RPS points or bestfit) and any dimensions are compared.

Deviation analysis is the fastest quality control method that compares the 3D scan with existing CAD data. The false color comparison shows the deviations in size and shape from the theoretical data set.

The 3D scan describes the entire surface of your component so that you can change the alignment at any time and thus open up the possibility for further analyses and evaluations.

  • Alignment and data comparison area-wide for the entire object
  • Nominal/actual comparison of sections, form elements and discrete points
  • Initial sample test report (EMPB)
  • Evaluation according to DIN EN ISO 1101 - GPS - Geometric Product Specification
  • Characteristic check according to shape and position from drawing
  • Virtual assembly of assemblies
  • Evaluation of machining allowances and wall thicknesses
  • Statistical process control / analysis of variance
  • Presentation of results in analogue and digital form

Your original component as a CAD model.

  • Complete recording of the original component
  • parametric structure of a 3D CAD solid
  • New design of individual parts on the basis of measurement data
  • Reverse Engineering of free-form surfaces (surface and solid models from NURBS)
  • Computer Aided Engineering (CAE) (simulation models - DMU, FEM, CFD, CAM)

For the fast creation of 3D data, the polygon mesh is the direct and currently fastest way to make digitized models available for further processing. We scan your object and deliver the 3D data - depending on customer requirements - as cut data, STL data or point clouds.

  • Waterproof polygonal model for 3D printing
  • Data basis for rapid product development
  • Control data for CNC systems.
  • Design: Design of new models
  • Art and Culture: Documentation, Restoration and Reproduction of Cultural Assets
  • Redesign of classic car parts

In the area of halls or building surveying we use terrestrial laser scanners for the measuring range from approx. 10m to 150m measuring distance. Using a laser scanner, the entire environment is completely captured using 3D point clouds and a 3D model is created at the CAD workstation.


Benefits for hall and building surveying

Your complete production halls as a 3D model.

A great strength of laser scanning lies in the large number of points that can be determined in a high point density on the surface of an object. With the help of more suitable software, CAD models are created from these point clouds. For this purpose we provide the CAD data in the common file formats DXF, DWG as well as IGES and STEP.

Depending on your further processing requirements, various Autodesk products such as AutoCAD + Revit or Inventor can be used to create the CAD data.

Building Information Modeling (BIM) enables architects, designers, engineers, manufacturers, CGI experts, developers and contractors to collaborate. By working with the same 3D building information model, projects can be designed, constructed and managed with greater efficiency and accuracy. sigma3D's 3D laser scanning service helps create a factual and accurate foundation that captures and expands the required dimensions of complex environments and geometries for BIM.

Once there - everything in.

Terrestrial laser scanning (TLS) is the ideal replacement for the classic manual measurement with tape measure and plumb bob.

There are no more kilometres between a missing measurement and you. You simply open the scanned building model with the software supplied by us and take the measure you need at the moment. For this purpose we provide you with the complete scan project, from which sections can be exported or measurements can be taken. Before this, the hall, the room, the piping system or your production facility is digitally, precisely and completely recorded. So you can't overlook anything anymore or missing dimensions can be easily determined by simply tapping into the software afterwards.

The 3D measurement avoids expensive journeys between the measuring location and the office:

  • Complete 3D acquisition of buildings, indoors and/or outdoors
  • Detailed and high-resolution recording of the system inventory
  • Measuring missing hand measurements at any time
  • Creation of plans based on 2D sections
  • Reconstructable representation of actual states
  • Further evaluations up to the CAD model

Of course, we are also happy to provide you with point clouds in the usual point cloud formats: FLS, PTC, PTS, PTX, XYZ, E57, ...

We would be pleased to inform you about our possibilities and advantages in a personal conversation. We are looking forward to your interest.
