The Finnish designer Janne Kyttanen has continued to develop his explosion ans creative welding techniques, melding volcanic stone and 3D-printed copper into two furniture pieces.

Janne Kyttanen is an artist and designer who is best known for his work in design for 3D printing. He is the founder of Freedom of Creation and the current Creative Director of 3D Systems, an American-based manufacturer of 3D printers.

The new side table and shelf join his prow-shaped Metsidian table, unveiled at last year’s Design Miami fair.

Explosion welding uses chemical explosives to bond materials that can’t be joined through conventional welding.

“[These] are dynamic works that represent a moment in time — an eruption that melds two divergent materials together,” said Kyttanen.

In Kyttanen’s collection, volcanic obsidian is melded together with a 3D-printed copper grid to form the furniture pieces.

“The result is a compelling metamorphosis; the impossible becomes reality,” he said. “Metsidian designs traverse the boundary between sculpture and furniture, a harmonious union of otherworldly form and everyday function.”

Kyttanen is a digital sculptor who has been at the forefront of 3D printing technology together with the studio he founded, Freedom of Creation.

In 2015 he produced a 3D-printed sofa made of a minimal mesh, informed by spiderwebs and silkworm cocoons.

He also created a range of shoes that can be 3D printed overnight from a digital file at home and worn out the next day.

Alongside the new Metsidian pieces, Los Angeles-based Gallery ALL is presenting a curated collection of Kyttanen’s other works as part of the Collective Design Fair in New York.

These include the infinite spiral of the Rollercoaster tables, exhibited in a sandblasted champagne finish, and the Sedona dining table in polished aluminium.
