Optimizing 3D Scans: What is the right shutter speed?
TL;DR: We tested the OpenScan Mini to determine how shutter speed impacts 3D reconstruction quality. We found photogrammetry is surprisingly robust to exposure variations. In our test, there's a w...
Optimizing 3D Scans: How Many Photos Do You Really Need?
TL;DR: Is more always better? When it comes to photogrammetry, the clear answer is no! We performed tests, which align with our experience, showing that there is an optimal number of images for tur...
Testing the influence of JPEG quality on the 3D scan results
TLDR: With high contrast surface preparation of the object, JPEG quality can be reduced to under 20% without any noticeable influence on the 3D mesh. Furthermore, the experiment indicates that the ...
Bambu Lab A1 Mini - InfiniMod - Endless 3d printing
TLDR How to modify existing gcode files (.gcode.3mf) for Bambulab A1 Mini for repetitive printing of the same build plate (PLA only!). Make sure to see the shortcomings/results Motivation We run a ...
Polarizer Module for OpenScan Classic
Cross-polarisation can greatly improve the image quality and thus the resulting 3D scans. Therefore, we have developed the polarizer module for the OpenScan Classic, that does exactly that. Left: w...
Worlds first fully automated 3d copy machine
It has been a long-standing dream to have a machine into which you can simply place an object, press a button, and obtain an exact copy. Through the power of open-source software and open hardware,...
