What is PLA?
PLA is a corn-starch-derived bioplastic, the most widely used 3D printing filament since 2014. It prints reliably at low temperatures (200-220°C nozzle, 55-65°C bed), produces minimal odor, and works on essentially every consumer printer without enclosure. Mechanical properties are solid for indoor decorative and light-functional use, but PLA softens above ~55°C ambient and degrades under direct UV.
Best for
- Decorative parts, miniatures, props, gifts
- Prototypes and form-validation models
- Indoor functional parts under low load
- Multi-color / silk / matte aesthetic prints
- Large display models (low warp risk)
Avoid for
- Outdoor parts (UV degradation in 6-12 months)
- Car interior parts (glove box temperatures soften it)
- Mechanical parts under sustained load
- Anything near heat sources (kitchen, machinery)
Printing tips
- Cool aggressively: part fan 100% after layer 2 for crisp overhangs
- Bed adhesion rarely a problem — most PEI and textured surfaces work without glue
- Retraction 1-3 mm direct drive, 4-6 mm bowden, prevents stringing
- Print speed 100-300 mm/s on modern CoreXY (Bambu, K1, Core One)
- Drying not required if spool is fresh and used within 6-8 weeks of opening
Cost notes
PLA is the cheapest reliable filament in 2026. Mid-tier brands (Bambu Basic, Hatchbox, PolyTerra) land at $19-23/kg in 5-kg bulk. Premium (Prusament, Bambu Matte) at $26-32/kg. Budget (Sunlu, Esun) at $13-16/kg. For LATAM imports add 35-50% over US sticker price. Material cost share on a typical 42 g part: 8-12% of total production cost.
