PLA

3D Printing in PLA

Polylactic Acid (PLA) is a widely used, eco-friendly filament for 3D printing, renowned for its ease of use and low printing temperatures. Derived from renewable resources like cornstarch and sugarcane, PLA is an excellent choice for creating detailed prototypes, decorative items, and low-stress functional parts.

PLA lacks the durability and heat resistance of materials like ABS or PETG, but its outstanding smooth finish and industrial compostability still makes it a popular option for many professional applications.

PLA Summary

Use PLA to print cost-effective prototypes and end-use parts for non-demanding applications

PLA is a great allrounder material that should be considered as the default material, if you are unsure which to choose. It's affordable, strong, and available in multiple colour options, with a great surface finish.

PLA Material Properties

PLA is a general use filament suitable for low-stress and low-temperature applications. It has an outstanding surface finish when printed, and is available in a wide variety of colours and finishes. PLA is one of the cheapest options for 3D printing at Printpool, so consider it for large prototypes and models that would be cost prohibitive in other polymers.
