3D Scanning

The volumetric accuracy (XYZ) is 0,020 mm plus 0,060 mm for 1 meter:

0,020 + 0,060 mm/m = accuracy

For example: When the largest dimension of a product is 200 mm: 0,020 + (0,060 x 0,2) = 0,032 mm.

The calibration report of the HandyScan 700 is available at request.

The scanning itself doesn’t really take much time. For an average part several hours, including preparation.

Depending on the aim and type of part reverse engineering takes most of the time. This depends most on complexitiy of the part. Furthermore there’s some interpretation involved on tolerances for example. For example if a dimension of 23,673mm is measured; was this meant to be 23,5 +0,2 or 23,75H7? 

Most important is to define the desired output. Is the file needed to compare to an existing CAD file, or is needed to fully reverse engineer the design?

For creating a featurebased model based on solids (and surfaces if necessary) for example for CNC machining an STL file is used regularly. This file type is based on a large number of triangles representing the threedimensional object. This file can be used to take measurements and to compare to native CAD.

Some file types that are common used:

• STEP (.stp)
• IGES (.igs)
• STL (.stl) 
• Solidworks (.sldprt / .sldasm / .sldrw)
• ParaSolid (.x_t / .x_b)
• ACIS (.sat)
• AutoCAD (.dwg)
• CATIA (.CatPart)
• PTC Creo (.prt)
• Autodesk Inventor (.ipt)

3D scanning often takes place at critical moments. For example when a machine is down because of a broken part or when a machined part is finished and needs to be ready for transport.

It’s preferable to plan 3D scanning ahead, when you have an urgent case please get in touch directly: +31 132 600 018

The HandyScan is a mobile (hand)scanner and therefore is often used at site. It’s also possible to send products directly to Estema.

For parts smaller than few centimeters or larger than 3 meters it can be better to choose another type of scanner. 

No.

Depending on the objects’ color it can be desired to use a non-reflective coating. Most of the time this is not needed with the HandyScan but in some cases it can drastically improve results. The spray we use is easily removable and not dangerous. Certificates are available at request.

For 3D positioning during scanning markers are placed on the product. Sticky or magnetic markers are used. Markers and any residue are always completely removed. If one of your products has surfaces where markers could be of any risk please mention this. 

Normally only geometry than can be seen by eye can be scanned. Possibly difficult situations can be deep holes, hard to reach areas and parts covered by shade. This differs a lot and can be estimated beforehand by picture.

Thanks tot he HandyScan being a mobile (hand)scanner not much is needed. A dry location and a wall outlet most of the time’s will do.
