PLA — Polylactic Acid
The most widely used FDM material. Easy to print, great surface finish, biodegradable.
FDM
PLA
Standard Polylactic Acid
FDMBiodegradable
The entry-level filament for good reason. PLA is derived from corn starch, prints cleanly at low temperatures, and produces excellent surface detail. Best suited for visual models, prototypes, and light-duty indoor parts.

PETG — Polyethylene Terephthalate Glycol
The sweet spot between ease of printing and real-world performance. Chemical and moisture resistant.
FDM · Engineering
PETG
Polyethylene Terephthalate Glycol
