Elegoo PLA Galaxy Black 1 kg

PLA filament 1.75 mm is the most versatile material for the FDM printing technology, suitable even for printing large objects. Thanks to its straightforward properties, we recommend PLA to all beginners starting with 3D printing. Another great advantage is its 100% biodegradability, as PLA is made from renewable resources such as corn starch. PLA is rigid and durable like other plastics, but it is not suitable for outdoor use, as it degrades and becomes brittle under UV light.

PLA surface finishing

The material is difficult to sand; sanding (friction) generates heat, which causes “stringing/pulling” of strands from the print. Therefore, during hand sanding it is recommended to cool the print, for example by wet sanding. For the same reason, drilling holes in the print is also difficult (again, heat buildup). It is advisable to first spray the part with a filler/primer (putty used in modeling) and then sand and clear-coat it, repeating as needed—until the surface is completely smooth—and finally spray with paint.

Gluing PLA

Cyanoacrylate (super glue) with an aerosol activator (sometimes the super glue alone may be sufficient).

Recommended PLA print settings

Commonly used nozzles are suitable. You can choose diameters according to the surface detail you want to achieve or according to the selected layer height. Printing temperature: 210 °C. PLA filament benefits from a heated bed, and for better adhesion it is recommended to heat it up to 55 °C. We also do not recommend enclosing the printer when printing PLA; keep it open. For a quality surface finish, the plastic needs to be cooled as quickly as possible after the nozzle. We therefore recommend setting the part cooling fan on the printer to 100%.

We supply the filament vacuum-sealed together with a desiccant 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.
