3D Scanner - Android based

NO, this is not Starship Enterprise even though It looks like.

It is my interpretation of a 3d Scanner. With a few additionally parts, an android phone has all the capabilities to help you

3D scanning an item of interest.

Just follow the instructions!

Highlights about this scanners are:

• small printing time, only the disk takes little more time
• No microcontroller and firmware needed, only laser and motor

I would really appreciate if you posted some fotos and some scan results!

Instructions

PartList:

• All the STL Files above once but 3dscanner_base two times
• An Android Phone or Tablet
• A red line laser like http://www.ebay.de/itm/281562839777
• A small rotating Motor (only 3RPM) like this http://www.ebay.de/itm/261549739071 . A Microwave motor like http://www.ebay.de/itm/261301609520 is probably also fine.
• 2 Aluminium square profile rods 10mm square - about 200mm and 300 mm length should be sufficient.
• 2 Aluminium round rods Diameter 8mm X 100 mm
• 2 M3x10 screws +_ 2 M3 nuts for inserting into the base
• A rubberband to mount the android phone

Assembly/Setup

• Print the parts
• prepare the rods
• insert the m3 screws and nuts into the base
• mount the motor into the motor house
• put everything together
• connect the laser and the motor electrically. I used a 12V power adapter and an LM7805 to supplpy the laser
• adjust the laser(1. adjust lens for minimal laser line thickness, 2 adjust laser to be exactly vertical, 3.) adjust laser to point exactly to center of dish)
• Get Android app "scan3doid" from the Google Playstore (make sure to use at least 1.3, older versions are quite unstable)
• Mount the Android Device to the phone holder
• Finish with the instructions in the Android App

Some hints for succesful 3D scanning

• First trial is not always the best. Retry with different settings to improve the result.
• Care for a good setup. What the laser does not touch, and the camera does not see, will not be translated to the STL File

Happy 3D scanning
