# Danish brand hand bends 3D printed seats to push large-scale extrusion post processing boundaries

Danish design studio Oberdoerfer & Krebs has presented two [3D printed seating pieces](https://www.voxelmatters.com/extrabold-and-honoka-show-off-resin-3d-printed-furniture-in-milan/) at Ukurant, a group show of emerging designers held during 3daysofdesign in Copenhagen. The Bend Chair and Bend Stool took large-scale extrusion as their starting point, then departed from the fixed side-profile silhouette that has come to define much of printed furniture.

Both pieces were printed flat using pre-programmed bend zones written into the toolpath. After printing, those zones were reheated until selected sections softened before others, at which point the pieces were bent into their final form by hand.

## Material states over material change

The studio printed the pieces in [colorFabb LW-PLA (lightweight polylactic acid)](https://www.voxelmatters.com/colorfabb-foaming-lw-pla-3d-printing-filament/), an expandable filament that causes middle layers to foam when exposed to specific temperatures, reducing material volume without switching to a different feedstock. 

By varying temperature and print strategy, the same filament can produce sections that differ in density and stiffness, giving the designers a way to work through material behavior rather than material substitution.

The Bend Stool originated as Krebs' third-semester project at the Royal Danish Academy in Copenhagen.

## A broader practice built on process interruption

Oberdoerfer & Krebs extended the same logic across two further projects shown separately. UpsideDown, a wall-mounted rack, was produced by deliberately sending the printer off-path mid-print, extruding plastic into open air and allowing it to sag before the machine resumed. Once cooled and flipped, the sagging material became functional hooks.

Human Layers, presented at the Biennale for Craft & Design, applied timed manual color changes to pellet-extrusion printing, drawing on the sequencing logic of ikat textile dyeing to control how pigment appeared across a printed vase.
