Prusament PLA Blend Viva La Bronze 970g
About PLA
PLA melts at a relatively low temperature of about 175 degrees Celsius. Unlike so-called thermoset materials, PLA can be heated past its melting point multiple times with very little degradation. It’s a hard material, but that also means it’s somewhat brittle, and once it breaks, it likes to shatter. Only this material is proven for 50 microns layer height.
However, PLA is not a perfect material and, just like every other plastic, has some disadvantages. The low melting temperature also means low-temperature resistance. Parts start to lose mechanical strength at temperatures over 60 °C.
The combination of being low in UV and temperature resistance means that it’s not ideal for outdoor use. Also, PLA is only soluble in chemicals like chloroform or hot benzene. So when connecting multiple pieces, you’re better off using just glue.
Even though PLA is on its own food safe, we do not recommend repeatedly drinking or eating from your 3D prints. Because of the small fractures on the print surface, bacteria can build up in there over time. You can prevent this by applying a food-safe coating. When post-processing PLA, it’s better to use wet sanding. Without water, you'll quickly start heating the plastic by friction, which will cause it to soften and make it hard to keep sanding.
Notes
This PLA is made in-house by Prusa Research.
1.75 mm filament is manufactured with precision of ± 0.02 mm (±0.03 for blends)
Before printing, make sure the surface of heatbed is clean as described in 3D Printing Handbook.
