OPENSCAN

Head-Scanner

Status: ongoing

Aim: Cheap and fast Scanner for human face/head and/or medium sized objects

+ first try of a multi-cam rig :)

Lessons learned: 

• Don't use longer camera cables as they won't work due to interference

• Wire Management is quite a serious business

• ...

OpenScan Cloud

Status: ongoing

Aim: Add various functions to the OpenScan User Interface, e.g. feature preview, feedback on the scan quality, possibly one-click online reconstruction

​

Lessons learned: 

• DSGVO is important

• There are great libraries available, that might have quite a potential..

Larger Scanner

Status: ongoing/paused

Aim: Larger Scan Volume

​

Lessons learned: 

• need new controller with support for 3 stepper motors + endstops

• difficult to control lighting

• aluminium extrusion is a great material and can be easily combined with 3d printed parts :))

Wheel-Scanner

Status: canceled

Aim: 3D Scanner using photogrammetry and one axis for the camera and one for the turntable

Lessons learned: 

• great feedback from the community

• quite inflexible, as the distance between camera and object can hardly be varied

• weak design, as the construction is quite wobbly

• PLA is a great material and surprisingly stiff and can be easily modified/filed

• compatible with the current scanner sketch and only minor changes to some parameters are needed

DIY Soldering Robot

​

status: activ

Aim: Automating the soldering process for small-scale production of the scanner control units

Lessons learned: 

• at the beginning the overwhelming feedback was: "this will never work"...

• after not even 20h in the process, I've achieved a success rate of 92/100 soldering points

• No need for professional equipement ;)

• a lot of fine-tuning of the tool-path and timing are necessary

• ...
