Prusament PLA Blend is our own in-house made filament. The whole manufacturing process is closely monitored and tested - we guarantee ±0.03mm precision and highly-consistent colors. You can inspect the parameters of every spool we made at prusament.com. Check the sample spool!
Manufacturing tolerance: ±0.03 mm (it is a blended PLA).
Warning: Last items in stock!
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.
The whole manufacturing process is closely monitored and tested – string diameter, color consistency, and mechanical properties – to make sure that every spool is perfect.
We believe the industry standard of 0.05 mm isn’t sufficient. We guarantee ±0.02mm precision for the vast majority of materials (±0.03 mm for blended materials), and highly-consitent colors.
We are the only manufacturer that gives customers the option to fully inspect parameters of every filament spool. Just scan a QR code on the spool to see all details online (check the sample spool).
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 both biodegradable and having low-temperature resistance means that it’s not ideal for outdoor use, not to mention low UV-resistance. 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 biodegradable, and the material on its own is food safe, we do not suggest to repeatedly drink or eat 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, it will melt locally and make it hard to keep sanding.
Easy to print

Hard and tough
This PLA is made in-house by Prusa Research. We chose Natureworks 4043D resin which is the best and most widely used in 3D printing.
This filament is manufactured with precision of +- 0.03 mm
Before printing, make sure the surface of heatbed is clean as described in 3D Printing Handbook.
Please note that due to the new and improved manufacturing process, the color has changed slightly comparing to the original Ms. Pink (Blend) batches.
