Prusament PLA Blend Pearl White 970g

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.

It's nice color, but you need to know one thing about it: it shrinks like CRAZY when cooling down.I compare to Prusa PLA White, Pearl Blue, Prusament Jet Black and Pearl Mouse. The Pearl White is unlike any of them in terms of thermal shrinking.For example if you load a filament with the extruder ~50-60mm above the bed the filament will never reach the bed -- it'll come one out of the nozzle but then start shrinking as the strand cools down and will rapidly shrink and shorten while getting thicker. It'll look almost like it's actually being sucked back into the nozzle. First time I saw I was amazed.The result of this is poor bridging, the first 5-10mm go fine, but then it cools down and start "pulling" from the nozzle and the bridge looks like "normal, super-thin, thicker, normal again", sometimes (rather rarely though) the bridge will actually fail as cooling down of the bridge will pull on the bridge so much it'll break it away from the nozzle.I never had issues with lifting though, but I maintain be print sheets very well, so I generally never had adhesion issues. But if your setup is prone to lifting I'd not be surprised if this filament gives you a bit more trouble than standard behaving one.So now I use it for solid prints with no details, overhangs, bridges, the models where rapid thermal shrinking is not an issue. For the future projects I'll stick to Prusa PLA White, it's been great.

Beautiful colour. A bit harder to print compared to non blend - small details don’t stick to smooth sheet but to you need to use satin one. Satin sheet, Bed 55, nozzle 215 first layer, the 210.

Super quality, as you would expect from Prusament. The pearl effect comes well with models which catch the light nicely.
