Dov Ganchrow 3D prints multicolored trucks using FDM

Dov Ganchrow prints multicolored trucks on a single-extrusion-head FDM (Filament Deposition Modeling) 3D printer using filaments composed of assorted color segments in his Purgey project. Through Purgey, the artist explores the intersection of technology and color. A notable feature of this FDM printing process is the creation of a purge block. As the printer switches between colors, it must clean the extruder by depositing excess plastic next to the printed object. This results in a secondary body, a randomly colored cube, forming beside the desired multi-colored object. In the case of the Purgey trucks, this purge block becomes a significant element. The trucks are printed standing on their heads, and upon completion, the purge block is moved onto the truck as its cargo, ready to be driven away.

Purgey Trucks’ design highlights the printing process

The reverse design process of the project by Dov Ganchrow starts by unraveling a virtual object to define the sequential color composition of the filament. The filament is then physically created by cutting and fusing different colored segments, which are heated and deposited to produce the final multi-colored object. The truck by the product designer adheres to a ‘no supports’ directive, leading to the creation of angled forms. One of the trucks carries a spool of fused filament, representing a stage before being printed along with its purge block, highlighting the process and the materialization of the object. Purgey Trucks was commissioned by the Holon Design Museum for the exhibit Colors. Dov Ganchrow, a professor at the Bezalel Academy of Arts and Design in Jerusalem, often creates works driven by curiosity and the potential of digital-physical shifts. The Purgey Trucks project, curated by Liora Rosin and Yuval Saar, embodies this approach, showcasing the intricate relationship between technology and color.
