PLA is the default filament choice and is suitable for most modelling applications, although has limited resistence to solvents and may be problematic in a laboratory environment where other materials may be more suited. The filament is cheap and non toxic, including during the printing process and is available in a very wide range of colours. The colours listed below are normally available in Teaching Labs, and their element assignments for molecular models are indicated along with the reorder code for Bambu. The filament reels include RFID tags allowing the printer to automatically identify the material and colour being used.

PVA is a water soluble printing material which is used to provide supports or support interfaces for models during the printing process. The filament can be easily removed following printing completion.

This is a more resistant plastic compared to PVA is is better suited for items used in the laboratory and has some resistance towards solvent splashes. However, the material requires higher printing temperatures and is significantly more expensive.
