DigiScan Dental and DigiScan Small Part Digitizer

Optical 3D digitizers for small objects and high accuracies

Being pushed by the availability of high speed and high precision image processing components, optical 3D scanners continue to find their places in an increasing number of demanding applications. This is where our DigiScan systems are defining new standards regarding result quality, user comfort, flexibility, versatility, and – last not least – cost-effectiveness. The measurement principle is based on a modification of the well-known structured light method (patent pending).

In many application fields there is a growing need for 3D replicae of physical objects that can not be created in traditional CAD. Numerous examples can be found in product design and presentation, manufacturing automization, and quality control. New and attractive applications coming up are in medical and anthropometric measurement (scanning human body parts or the entire body), requiring non-contact and reliable surface measurement in near-realtime, and in ergonomic design.

3D scanning of small and complex objects with high accuracies

Using standard 3D scanners from the market for digitizing small-sized or miniature objects is in general either impossible or does not produce satisfying results (due to low resolutions and/or accuracies, the inability to deal with mutiple or 360° scans, non-automatic operation, high pricing).It is especially this type of applications that DigiScan Dental Scanner and DigiScan Small Parts Scanner were developed for.

DigiScan Dental Scanner

The DigiScan Dental Scanner was exspecial developed for applictaions in a dental laboratory.
With the Dental Scanner it is possible to digitize as complete upper and lower jaws as well single teeth or bridges with a very high accurcy. The process of scanning and the post processing from a point cloud to a 3D model is automaticly. This is very comfortable for the user, because he doesn't need any previous knowleges of 3D scanning and he can work paralell during the scan process and post process.
The finished 3D polygonmodels of the DigiScan Dental Scanner have an accuracy of +-15µ and can used for other applications without problems.

DigiScan Small Part Scanner

The DigiScan Small Part Scanner was developed for scaning of small and complex objects but offers the same advantages like the DigiScan Dental Scanner. The DigiScan Small Part Scanner enables the semi- or fully-automatic capturing of small objects with a high level of resolution and detail accuracy. Not only from surface from given perspectives but also complete objects can easily and quickliy be scanned. For further use in downstream applications such as CAD/CAM, tooling & mold making, production (e.g. using a 3D printer), presentation; analysis, etc. standard formats are supported wich allow for direct model transfer into all respective software systems.

Typical objects for scanning with the DigiScan Small Part Scanner

- finger rings, gemsones, coins, medals, jewelry
- small technical parts like connector housing, screws, tools
- plastic mold parts
- small biological objects like bones, fossilized parts, etc.
- surface structures
- surface roughness
