Prusament PLA Opal Green 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.

+Nice color and sheen +PLA is easy to use +Good performance +Good bed adhesion -The stench I got this spool of filament to use on my Prusa Mini. Right out of the box it's a really nice dark green all the way through with a little glitter in it. The glitter is visible but pretty subtle in my opinion. I did have some jamming issues when I first loaded this filament but was able to determine the cause to be the PTFE lining in my hot end coming a little loose and letting filament leak around it rather than the filament itself. I started off with a 3d Benchy and was pretty happy with the results. Bed adhesion was great with the powder coated springsteel sheet with no adulterants on the surface. At Prusa Slicer's .25mm draft PLA preset the Benchy surface was smooth with no sagging around the bow of the ship and minimal stringing. The window bridges all looked clean without drooping and the smoke stack was solid and crisp without any appearing like melted wax. Next I ran off a low poly Bulbasaur at .15mm quality presets and it came out great. The ears are pointy and the top edge of the bulb is well defined. I particularly like the way the filament changes between shades of green depending on the thickness of the layer behind the surface and the orientation of layer lines in relation to the light. The filament is just slightly translucent so it can pass some light through from behind and I think this could make for some nice lighting effects in some objects. The only real problem I have with this filament is that whatever blend of plastics are being put into it smell awful when its hot. Personally I would say it smells like cat urine but I had someone else tell me it smelled spicy to them so your perception may vary.
