Bonsai Lab Inc showed a 3D printer using the fused deposition modeling (FDM) method as a toy and a filament whose melting temperature is 80°C.

The Tokyo-based company exhibited them at Spielwarenmesse, a trade show on toys, which runs from Jan 28 to Feb 2, 2015, in Nuremberg, Germany.

In general, 3D printers based on the FDM method melt filaments at a temperature of about 200°C. This time, Bonsai Lab employed the filament, "LT80 (Low Temperature)," with a low melting temperature to improve safety. It plans to release the toy, "BS Toy," at the end of 2015.

BS Toy measures only 200 (W) x 200 (D) x 200mm (H) and weighs 2.0kg but can form an object as large as 130 (W) x 125 (D) x 100mm (H). The standard diameter of its nozzle is 0.4mm, but Bonsai Lab offers nozzles with four different diameters ranging from 0.2 to 0.5mm. The recommended deposition pitch is 0.1mm.

LT80 is a flexible filament that Polymakr LLC developed for BS Toy. In consideration of the safety of children using the toy, the company used raw materials approved by the US Food and Drug Administration (FDA). The filament is also highly biodegradable. Currently, the filament is available only in one color (colorless). It will come in multiple colors when released.
