German designer Annika Frye has designed a rotation-moulded lighting range with visible seams.

The SEAM polymer plaster lights are created using a rotation-moulding machine, which Annika Frye constructed herself.

The lampshade evolved over months of experimentation with various mould shapes and additives such as wood and textiles.

The process is made up of three stages by incorporating various coloured layers into the product.

Firstly, the mould is screwed together and attached to the centre of the machine. The mould is then filled with the first polymer plastic mixture.

The machine moves in three separate rotations simultaneously, powered by an electric motor. The liquid covers the inside of the mould.

After drying another coloured layer of mixture is added to the inside of the mould and the rotation process is repeated.

The mould is discarded after final drying, leaving the product with a smooth outer surface and the seam of the mould visible.

The bottom of the lamp is cut off and sanded, revealing the irregularities of the casting process on the inside.

The light comes in three colours, green, white and red and the fixture is made from sandblasted plexiglass.
