Memory Forest explores the relationship between digital and craft processes, and between wood and aluminium. Sections of a birch tree from a garden in Cologne were 3D scanned, digitally edited and 3D printed before being transformed into aluminium and bronze casts. The tree had been suffering from the effects of living in the city and was eventually cut down, making the scans a way of recording a memory of it. The project explores emotional attachment to trees and human dependence on them, while questioning how they are treated as material resources. Throughout the process, human and technological errors create glitches that become part of the final objects.
