"otto & alwin" in colour

Vor einigen Jahren hatte ich "Otto & Alwin" modelliert,  bekannte Comicfiguren aus dem DDR-Pioniermagazin Frösi. Dank des 3D-Druck-verfahrens konnte ich beide endlich reproduzieren, vor allem kleiner als im Original. Ob sie nun in Farbe ihrem Erfinder Jürgen Günter gefallen hätten? Some years ago I sculpted "Otto & Alwin" two comic characters from the GDR magazine Frösi. Now I was able to 3D-print them in a preferred smaller size. Finally painted with colours I wonder if they would have got the approval of their creator Jürgen Günther...

Aber um zu diesem Resultat zu kommen, bedurfte es vorher noch ein paar Arbeitsschritten, die es zu durchlaufen galt: 3D-Scan per Photogrammetrie, 3D-Druck,  Bemalung mit Pinsel und Farbe. In order to get these results some production steps had to be carried out beforehand: 3D scan using photogrammetry, 3D printing, painting with waterproof colours.

Above: up to 150-200 photographs where shot, from as many angles as possible so the software 3DF Zephyr could calculate a detailed 3D model. Before the calculation process, masks needed to be created to separate the object from the background. Right: to correct and clean-up minor surface errors Blender was used. Below: the different stages Alwin went through.

Otto needed some tinkering to figure out how to divide the 3D model into suitable printing parts (I am still looking for a better solution).

Ich könnte mir gut vorstellen, mein 35 Jahre jüngeres Ich hätte diese beiden Figuren liebend gern und mit leuchtenden Augen in den Händen gehalten... I could imagine my 35 years younger self would have loved to hold these figurines in his hands...big-eyed with delight.
