10 Differences Between pla and pla+

What is PLA?

PLA, which stands for Polylactic Acid, is a biodegradable thermoplastic polyester derived from renewable resources such as corn starch, tapioca roots, or sugarcane. It is widely used in various industries, including packaging, medical devices, 3D printing, and more. PLA is known for its eco-friendly nature and its ability to break down in composting facilities.

Examples of PLA

– Disposable cutlery and food containers
– Packaging materials
– Medical implants
– 3D printing filament
– Biodegradable plastic bags

What is PLA+?

PLA+, or PLA Plus, is an enhanced version of PLA that offers improved mechanical properties, durability, and heat resistance compared to traditional PLA. It is formulated by adding additives to the PLA polymer, resulting in a stronger and more robust material. PLA+ is often preferred for applications requiring higher performance and strength.

Examples of PLA+

– Industrial prototypes
– Functional parts
– Automotive components
– Musical instruments
– Engineering applications

Differences between PLA and PLA+

Difference Area PLA PLA+
Strength Relatively lower strength Higher strength
Tolerance to heat Lower heat resistance Higher heat resistance
Printability Easier to print Slightly harder to print
Surface finish Less smooth surface finish Improved surface finish
Flexibility More flexible Less flexible
Impact resistance Lower impact resistance Higher impact resistance
Price Lower cost Higher cost
Availability Widely available Less common
Shelf life Shorter shelf life Longer shelf life
Environmental impact Biodegradable and eco-friendly Biodegradable and eco-friendly


PLA and PLA+ both have their unique characteristics and applications. While PLA is suitable for general use and offers good biodegradability, PLA+ provides enhanced strength, durability, and heat resistance. The choice between the two depends on the specific requirements of the intended application.
