3D scanning with Next Engine

Setup Controls

Scan

• Enter the Scan Panel by clicking the Scan button
• 360:
  • - Select the "360" scan option in the scan panel to scan the object from every angle.
  • - The number of divisions will control the degree of rotation between scans and the total number of

scans

• • - The individual scans will be grouped as a family.

I had a thing that was about 250 mm height, so I chose

• Wide = 0.015" accuracy, 10x13" field of view
  • - Place object 17 inches from the front of the scanner

Align

• Click on Align
• Alignment for 360
  • - Place 1 pin on a common location between 2 scans within the family.
  • - Drag the pin to the location or double click on the point to place the pin.

• Connect the 3D scanner tool with the Modela

• Load the object to be scanned on the 3D scanner

• Start Dr. Picza

Choose the communicaton port

• Click File -> Preferences
• Choose the communication port. (e.g. COM1)
• Click OK

Set the scanning conditions

Choose Scanning Area:

Make the settings for X scan pitch and Y scan pitch

• X scan pitch:
• Y scan pitch:
• Z -Bottom : Set the height of the Z reference surface.

Double click to make the sensor descend at this location

Z-upper limit.

• Set the upper limmit for the height of the scanning area
• Double click to check out if the right point is selected.

3 D Scanner Cola scanner

Project with Saethor Vido based on the idea of the Milk Scanner . Since we didn't get the program to work on that site we copied the ideas based on our knowledge.

• Put item in container.
• Take picture (use tripod and keep the camera still)
• Pour fluid with contrasting color to the item, 0,5 dl
• Take picture after every filling until you have filled above the item.
• Use Gimp or other photo editor to increase contrast set images in monochrome
• Use Inkscape or other 2D Vector program to trace bitmap and turn it to vector.
• Save vector-images as .svg
• Open Blender
• Import each .svg file to blender
• Go to edit mode and extrude each .svg equally.
• Align model together and save as blender file.

3 D print of Cola-scanned item

• This is actually not real 3 D print.
• Use the .svg files, that we had
• Set strokes to 0,01 mm save as .pdf
• Laser cut in cardboard.
