Prusament PLA Galaxy Purple 1kg

What can you expect?

Prusament PLA is our own in-house made filament. The whole manufacturing process is closely monitored and tested - we guarantee ±0.02mm precision (± 0,03 for blends) and highly-consistent colors. You can inspect parameters of every spool we made at Check the sample spool!

Manufactured In-House By Josef Prusa

We were not satisfied with the quality of filaments on the market. So we decided to make our own! Prusa Research is the only 3D printer manufacturer with its own filament production.

Premium-Grade Materials And Thorough Testing

The whole manufacturing process is closely monitored and tested – string diameter, color consistency, and mechanical properties – to make sure that every spool is perfect.

± 0.02 mm Manufacturing Guaranteed Precision

We believe the industry standard of 0.05 mm isn’t sufficient for perfect 3D printing. Instead, we guarantee ±0.02mm precision (± 0,03 for blends) and highly-consistent colors in our filaments.

High Quality You Can Check Yourself

We are the only manufacturer that gives the option to inspect parameters of every filament spool. Scan a QR code on the spool to see all details online (check the sample spool).

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.

One of my absolute favorite colors - all the Galaxy filaments are just fantastic. As another reviewer mentioned, ignore the over-exposed photo of the vase and Thanos bust - in reality it prints darker, more like the lion photo. Personally I couldn't ask for a more perfect shade of dark purple.

This PLA is great! It prints really well, there really is almost nothing to tweak when using the default PrusaSlicer profile, it just prints great out of the box. Don't be mislead by the Thanos photo though, the colour is much darker and closer to the lion in the first photo. Single perimeter prints look almost translucent, but add 2 more walls and it becomes a rich dark purple. The glitter effect is very dependent on the light, sometimes it's barely noticeable, sometimes it's a sky full of stars. Very cool to look at from different angles. The prints themselves come out well, the filament holds the details well. IMO worth the price.

Considering a review rectification is tough -- there was stock, and I straight up ordered a whole bunch of rolls. Loaded them in my plastic rocket (RatRig V-Core + High Flow nozzle), and the tiny-rocket (Prusa Mini), and started printing -- the result, a D&D Mind Flayer inspired ship, is absolutely stunning. This filament plays nicely with light, and has to be seen to be appreciated (the effect is hard to photograph). Frigging loving it. Plastic rockets had no issue printing it as well - the V-Core 3 was set to 200mm/s print speed and it had absolutely no extrusion issues, skipped steps (LGX + Mosquito Magnum), or distortions compared to the off-the-shelf Prusa Mini. This is a high quality, high performance PLA that's well worth the money for high detail prints that also are really tough (and the rolls are great).
