• 100 data acquisition lines
• Enlarged scan area 312X204mm
• works up to an accuracy of 0.05mm
• Uses white light pattern
• highly efficient in capturing 3D models of medium to large objects
• Easily expanded with computer-controlled turntable or a color camera.
• It catches fine details, so it’s good for scanning geometrically complex objects
• Scans with precision and speed

A competitive 3D scanner, preferable for scanning small to medium sized objects and perfect for industrial and personal use. It has these features:

• Dual cameras to deliver high resolution scans
• Automatic scanning of whole objects with one click
• Active synchronization of model and camera views, allowing you to easily see the scanning positions and go for a rescan where needed.
• Automatic calibration that is convenient and lets you scan an object with a single click
• 3-axis turntable (TA300+) to facilitate scanning beyond limits
• Install on a tripod to scan larger objects
• No manual registration or targeting needed
• (Desktop HD Scan) 20fps 1,100,000 points / s

This handheld self-positioning scanner is perfect for industrial problems and features:

• Dynamic referencing, for high resolution images even with movement
• Can capture fine details
• High accuracy 0.025 mm (0.0009 in)
• Measurement rate of 1,300,000/s
• Can scan a large area (11 laser crosses)
• Lightweight, portable and requires no tripod or other devices to operate

A 3D scanner that uses blue light technology and is capable of measuring millions of points per scan. It has the following capabilities and features:

• Easily detects shiny surfaces, fine edges and fissures
• It’s great for inspection analysis
• It can measure and inspect objects of different sizes, from small to extra large
• Triple Scan functionality allows for scans in any type of lighting, faster, accurately and with less scan requirements
• The scanner is photogrammetrically expanded, allowing it to capture multiple components at the same time.

While doing reverse engineering manually, we are able to generate parametric features wherever useful. These features can be used on parts with regular geometry in every CAD software.

Parametric features are very beneficial when working with CAD files.

• 3D scans – for example clay models, as explained in the sample above
• Simulations – FEM, ANSYS or material flow in moulds (Cadmould / Moldflow)
• Optimizations – product tolerance optimization (GOM inspect Pro)

When working with 3D scan data, we follow these steps to remodel into parametric CAD data:

1. Make an impression on paper
2. Build detailed units of the model
3. Modify the units until they fit on the pointcloud
4. Add parametric features to the units
5. Remodel the units some more
6. Continue adding parametric features
7. Compare pointcloud and cad data regularly to ensure fit
8. Assemble the parts together
9. Double check to ensure tolerances between STL and CAD data are below requested figures.

If tolerances are not reached, the engineer will modify the structure into smaller elements and go back to step 5 of above list, until his reverse engineering arrives at the required tolerance.

Pointclouds in this case, are a result of simulations done with original straight and clean CAD data. Each simulation affects the structure of the original file. As a result, we need to rebuild many free forms faces and implement the models into the original CAD software.

The general steps followed when creating native CAD data from Pointclouds based on simulation data include:

1. Check original CAD and pointcloud after simulation
2. Identify geometrical parts and free form faces
3. Rebuild first geometrical units of the model
3. Modify the units until they fit on the pointcloud
4. Rebuild free form areas and implement them into the geometrical base
5. Continue remodeling the units further
6. Compare pointcloud and CAD data regularly to ensure allowable tolerances
8. Assemble all the parts together.
9. Ensure requested tolerance between simulation file and CAD data are below requested figures

If tolerances can‘t be reached on the first attempt, the engineer will modify the structure into smaller elements and progress from step 5 of the above list, until the target tolerance is reached.
