Dasyn joined 46th Design Festa, which was held on November 11 to 12 at Tokyo Big Sight. Main focus in this time was Christmas, although it is still long time to Christmas. A Christmas tree with a set of illumination LEDs with 3D-printed shades and with 3D-printed ornaments was displayed. Bulbs with 3D-printed covers, light and transparent globes, and USB stands and pendants with 3D-printed shades were also displayed. These shades and ornaments were printed by the helical 3D printing method using transparent plastic (PLA).
