PLA, Resin, Wood-Fill: A Material Guide
The honest differences between the materials we use — and why we choose each one.

A Material Guide
We work with five material families. None of them are perfect. Each is honest about what it is.
Matte PLA
Plant-based. Cool to the touch. Beautiful in off-white and sage. Suitable for almost any indoor object.
Wood-PLA Blend
PLA mixed with recycled wood fibre. Has the grain of wood and the printability of plastic. Develops character over time, like wood.
Marble-PLA
Mineral-filled PLA. Dense, weighted, closer to stone than plastic. The Quiet Bookends are made from it.
Concrete-Look Resin
Slate-toned, urban, sculptural. Used for our larger wall pieces and sconces.
Recycled PETG
Post-consumer recycled. Strong, sharp, sustainable. The black Madras tray is PETG.
