Elegoo PLA Silver 1 kg

PLA filament 1.75 mm is the most universal material for FDM printing technology, also suitable for printing large objects. Thanks to its easy-to-use properties, we recommend PLA to all beginners starting with 3D printing. Another great advantage is its 100% ecological biodegradability, as PLA is made from renewable sources such as corn starch. PLA material is hard and durable like other plastics; however, 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 strands to be “pulled” out of the print. Therefore, when 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, a heating issue). It is advisable to first spray the part with a filler/primer (a putty used in modeling), then sand and clear coat, and repeat as needed until the surface is completely smooth; finally, apply the top color.

Bonding PLA

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

Recommended settings for printing PLA

Commonly used nozzles are suitable. You can choose diameters based on the surface finish you want to achieve or according to the layer height settings during printing. Printing temperature: 210 °C. PLA filament benefits from a heated bed; for better adhesion it is recommended to heat it up to 55 °C. We also do not recommend enclosing the printer for PLA prints; keep it open. For a high-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 vent pattern or color. We strive to maintain 100% repeatability of winding and spool color.
