This is a brand new type of filament, as the actual colour changes by UV light, just pop it outside and watch it transform! So sit back, watch the video below, marvel at its properties.
Please note, following several tests by customers and ourselves, we have found that the UV colour change reaction only lasts for about 3 weeks if the print is kept outside 24/7.
The filament is delivered to you FREE OF CHARGE in a sealed, clear plastic bag, complete with a sachet of silica gel.
The frequency of UV light is from 100~400nm (thanks Daniel) You can view the wikipedia entry on Electromgnetic Spectrum here
