Buddy3D PLA 1kg · Technical features from Buddy3D.

Buddy3D is a high-quality, reliable filament made for 3D printing at a reasonable price. This filament is manufactured in European facilities under the supervision of Prusa Research. That means faster shipping and lower import duties where applicable.

PLA is the easiest material to print and the first choice of most users, thanks to its good looks. It is inexpensive and suitable for beginners and advanced users alike. It is capable of printing both large and detailed models, figures, and quick prototypes that don’t require increased resistance.

The Buddy3D PLA has low shrinkage, which makes it possible to print large objects with little to no warping. This is especially useful for printing huge models glued from multiple parts.
The low melting temperature in combination with fast cooling enables easy printing of detailed parts, bridges, and overhangs.

New spools with OpenPrintTag
Starting July 2026, new Buddy3D filaments ship on a spool equipped with a fully rewritable NFC tag powered by the OpenPrintTag standard.
The OpenPrintTag attached to your Buddy3D spool contains essential data about the material and can be read with the Prusa mobile app. It works entirely offline, is free to extend, and is open for anyone to build upon.

To achieve the best adhesion, it is important to keep the surface clean. The best option is Isopropyl alcohol available in drugstores, which works the best for PLA and other materials as well. Pour a little amount on an unscented paper towel and wipe the print surface. The print sheet should be cleaned while cold for the best results.
PLA is less hygroscopic than most materials, so drying is not usually necessary. However, if you notice stringing, bubbling, or surface roughness after long storage, drying at 45–50 °C for 4–6 hours will usually resolve it.
When post-processing PLA, it’s better to use wet sanding. Without water you’ll quickly start heating the plastic by friction, it will melt locally and deform. Also, without water, the sanding material would clog easily.
PLA parts can be joined with suitable adhesives; Prusa recommends superglue for many applications. Solvent response varies with formulation, additives and colour, so do not assume all PLA can be solvent bonded in the same way.
