What is Replitech PLA Recycled filament?

  • 2 min read

At Replitech, we make premium, high-quality 3D printing filament. To ensure the filament meets the high standards of quality we aim for, we established a carefully tuned manufacturing process. We continuously monitor the process parameters such as the filament diameter accuracy, the ovality and the colour consistency.

However, extruding 3D printing filament is very delicate and depends on many parameters. We try to keep as many as possible under control. Still, sometimes some of them vary for minimal periods, for reasons out of our control. As a result, there might be instances where the spool would not meet the quality standards we promise. During extrusion, we continuously measure the diameter of the filament on two different axes, so we know for sure the variation for each spool. We also label this information on each spool so that every customer will know their specific spool dimension variation exactly. For some spools, on 600m of filament length, the diameter accuracy is within ±0.02mm. Such spools will fit our "Precision" filament range. For others, the accuracy is within ±0.05mm. Such spools will fit our "Everyday" range, and we pack and label them as such.

Crashed filament material for recycling

Still, there are some spools for which the variation limits jump more than ±0.05mm. These are not passing the QC checks. Some spools do not pass the QC checks due to inconsistencies in colour or ovality.

We recycle the material in these spools. We make sure we protect the material against contamination. We crush, dry, and extrude it again into these "Recycled" filament spools colouring them in black or dark green.

However, this "Recycled" filament is NOT a premium material.

Our premium PLA - "3D850", "Vivid", and "Sleek" lines are meant for high-quality 3D printed parts. Those parts would be made from material melted only two times - once when we extrude it into filament and again when it is extruded from the customer's 3D printer nozzle into the printed part. We use the base resin 3D850 PLA from NatureWorks to manufacture these premium products. This was specifically developed for 3D printing. The scientists put a lot of research into ensuring that this process of melting the material twice will result in 3D printed parts with the proper qualities and properties.

Replitech Recycled filament

When you print the "Recycled" filament, you will get a part that would have been melted three times.

However, the "Recycled" filament will work fine for many use cases. We tried it extensively and did not encounter printing problems.

Have fun printing and
Embrace the layers!
