Prusament PLA

PLA - THE EASIEST MATERIAL TO PRINT
It is inexpensive and suitable for both beginners and advanced users. It is capable of printing detailed models, figures and rapid prototypes that do not require increased mechanical, chemical or temperature resistance. PLA is the most widely used filament, known for its beautiful appearance and ease of printing. It is an excellent choice for large objects due to its low thermal expansion, resulting in minimal deformation. At the same time, its low melting point also makes it suitable for small parts. While PLA may not be as strong or durable as some advanced materials, its versatility makes it ideal for a variety of applications, including large objects, miniatures, concept models and prototypes that do not need to be extremely durable.

What can you expect?

Prusament PLA is our own filament, manufactured in-house. The entire production process is closely monitored and tested – we guarantee a precision of ±0.02 mm (±0.03 for blends) and very consistent colors. You can inspect the parameters of every spool we produce at prusament.com. Check out the sample spool !

Manufactured in-house by Josef Prusa

We weren't satisfied with the quality of the filaments available on the market. So we decided to make our own! Prusa Research is the only 3D printer manufacturer with its own filament production.

Premium quality materials and thorough testing

The entire production process is closely monitored and tested – wire thickness, color consistency and mechanical properties – to ensure that every single spool is perfect.

± 0.02 mm guaranteed production precision

We believe that the industry standard of 0.05 mm is not sufficient for perfect 3D printing. That's why we guarantee ±0.02 mm precision (±0.03 for blends) and highly consistent colors in our filaments.

High quality you can control yourself

We are the only manufacturer that allows you to inspect the parameters of each filament spool. Scan a QR code on the spool to see all the details online ( check the sample spool ).

Before printing, you should read our dedicated article and materials table on preparing printing surfaces.

Basic properties

Tips and tricks for beginners
Popular among both beginners and advanced users

PLA is the easiest filament we make. It is reliable and does not require any special print preparation or complicated post-processing methods. If you are new to 3D printing, it is best to start with PLA before moving on to other materials.

Grinding

When finishing PLA, wet sanding is the best choice. Without water, you will quickly heat the plastic through friction, causing it to melt locally and deform. In addition, the sanding material will easily clog without water.

Gluing

PLA can be bonded with many different types of glue. We recommend using superglue for most parts. Some PLA filaments can also be bonded with acetone, but this depends largely on the additives and colors used.

Notes

• This PLA is manufactured in-house by Prusa Research.

• 1.75 mm filament is produced with a precision of ±0.02 mm (±0.03 for mixtures).

• Before printing, make sure the surface of the heated bed is clean, as described in the 3D Printing Handbook .

• If you choose a 2 kg spool, download and print a holder for 2 kg spools , as it will not fit on the standard holder that comes with it.

• Follow the instructions in Prusa's article if you need to dry the filament.
