Coil of 1kg PLA phosphorescent diameter 1.75mm compatible with 3D printers Up! Box, Up! Plus 2 and Up! Mini from TierTime.

PLA (polylactic acid) is biodegradable because it is made from renewable materials (corn starch). One of its main features is its small shrinkage in 3D printing, which is why a hot plate is not needed when printing.
