Case Study: Deeptime achieves studio-quality, design-forward 3D-printed speakers with ExOne sand 3D printing

How a small startup in Czechia is challenging the giants of the audio industry with the help of 3D printing

Deeptime, a five-person startup in Bustehrad, Czechia, set out to create visually striking desktop speakers that deliver studio-quality sound without the bulk or cost of traditional monitors. Faced with the limits of conventional MDF enclosures and plastic 3D prints, Deeptime partnered with ExOne and its binder-jet sand 3D printing services (via the ExOne Adoption Center) to realize complex, non-box housings that match both aesthetic and acoustic goals.

ExOne prints the raw sand housings at its Adoption Center in Germany and ships them to Deeptime within about seven days; the parts are then impregnated and slowly cured over two months to become airtight and dense. A two-year study at Brno University of Technology verified the result: the ExOne-produced sand structure is 86% more rigid than MDF and yields double the internal sound damping, enabling Deeptime’s Spirula speakers to achieve markedly better acoustics and distinctive organic designs—backed by ExOne’s fast turnaround, quality and professional support.
