PLA filament 1,75 mm is the most universal material for FDM printing technology, suitable even for printing large objects. Thanks to its easy-to-use properties, we recommend PLA to all beginners starting with 3D printing. Another big advantage is its 100% ecological degradability, as PLA is produced 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.

PLA Surface Treatment

The material is difficult to sand; during sanding (friction), heat is generated, which causes "dragging" of fibers from the print. Therefore, manual sanding is recommended to be done while cooling the print, for example by sanding under water. For the same reason, it is also difficult to drill holes into the print (again, heating issues). It is advisable to first spray the material with a filler (putty used in modeling) and then sand and paint over it again and again - until the material is completely smooth, and finally finish with paint.

Gluing PLA

Superglue with a spray activator (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 quality print surface, the plastic behind the nozzle needs to be cooled as quickly as possible. We therefore recommend setting the plastic cooling fan on the printer to 100%.

We supply 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 differ in embossing or color. We strive to maintain 100% repeatability of winding and spool color.
