PLA filament 1,75 mm is the most universal material for FDM printing technology, suitable even for printing large objects. Thanks to its simple properties, we recommend PLA to all beginners starting with 3D printing. Another great advantage is 100% ecological degradability, as PLA is made from renewable resources such as corn starch. PLA material is hard and durable, like other plastics, but it is not a material suitable for outdoor use, as it degrades and becomes brittle under UV light in such cases.

Surface treatment of PLA

The material is difficult to sand during sanding (friction) as heat is generated and this causes "pulling" of fibers from the print. Therefore, during manual sanding, it is recommended to cool the print, for example by sanding under water. For the same reason, it is also difficult to drill holes in the print (again, a problem with heating). It is advisable to first spray the object with filler (putty used in modeling) and then sand and repaint and again and again - until the surface is completely smooth and finally spray with paint.

Gluing PLA

Superglue with an activator spray (sometimes superglue alone may be enough).

Recommended settings for PLA printing

Commonly used nozzles are suitable. You can choose diameters according to the surface fineness you want to achieve or according to the layer thickness settings during printing. Printing temperature: 210 °C. PLA filament requires a heated bed, but for better material adhesion it is recommended to heat it up to 55 °C. Furthermore, we do not recommend covering the printer in an enclosure for PLA filament printing, or leave it open. For a high-quality print surface, it is necessary to cool the plastic behind the nozzle as quickly as possible. We therefore recommend setting the plastic cooling fan on the printer to 100%.

We deliver the printing filament vacuum-packed along with a moisture absorber and placed in a cardboard box. The plastic spools on which the filament is wound may vary in embossing or color. We try to maintain 100% repeatability of the winding and spool color.
