rPET is a material, that is made from 100% recycled PET bottles.

The advantages of this material include: good flexibility and strength, good adhesion, environmental friendliness and 100% recyclability.
Due to its mechanical, thermal, chemical resistance and dimensional stability, it is great for printing large objects.

Despite all its advantages, however, it also has disadvantages, such as high moisture absorption and complexity of printing. For this reason, we recommend it to highly experienced printers who are determined to “play around” with the material a bit and find the right print settings for their printer.

If you have no experiences with rPET filament we recommend to order this small testing package before you order a big 1kg package.

Storage condition

  • Store in a dry environment and protect from air humidity

  • Or you can also use filament or fruit dryer.

Recommendations for printing the rPET material.

First of all, it is necessary to ensure that the filament is thoroughly dried, which is why we recommend drying the new filament before using it. We dry it in a hot air oven at 60-70°C for at least 6 hours, you can also use a modified fruit dryer or filament dryer, from which you can print the material directly and thus eliminate re-absorption of any moisture.

We recommend printing our material at 250-260°C with a heated bed set to at least 80°C. For printing we advise to use a 0.6 mm nozzle, but with the correct setting and after drying the filament, it is possible to use a 0.4 mm nozzle without any problems. For successful printing, we also recommend the use of either a heatbreak with a teflon tube, which must be shortened to the same length as the end of the heatbreak, or an all-metal titanium heatbreak (ordinary all-metal iron heatbreak has a high tendency to stick and clog).

rPET material works better at higher speed. The same applies to the first layer, for which we recommend setting the speed to at least 70% of the speed compared to the other layers.

It is not advisable to leave the material even for a short time without extrusion and it is therefore necessary to ensure a constant flow, otherwise the extruder and nozzle will become clogged.

The back pressure of the bed and the nozzle at the first layer simultaneously limits the flow and the collection of material in the heating part of the extruder. This can be partially changed by moving the nozzle away from the bed, but this is not always sufficient. Therefore, it is advisable to manually replace the material after completing the first layer using the following script:

(For Simplify3D copy to the section: Scripts and Additional terminal commands for post processing).

{REPLACE ” Z = ” ” Z=”}
{REPLACE “nM117 Layer 1, Z=” “nG1 X10 Y5nM600nM117 Layer 1, Z=”}
{REPLACE “nM117 Layer 2, Z=” “nG1 X10 Y5nM600nM117 Layer 2, Z=”}

Here are a few tips and recommendations from a successful printer who is using our rPET material:

In my experience, “the best recipe” is to use an all-metal titanium heatbreak and print at 260°C without using a cooling fan or with just a small amount of blow. I recommend using a 0.6 mm nozzle, but with correct setting it is possible to use a 0.4 mm nozzle as well. I have not noticed any problems with slow printing, and I found that it was not even necessary to maintain a constant flow as otherwise recommended. But when printing large, complex, or complicated objects, I recommend putting a sponge with a few drops of oil on the string just to be sure. It does not affect the strength of the object and when using the sponge, it never happened to me, that the hot end would clog.

Most importantly, with rPET material it is practically impossible to print unless it is completely dry (even right out of the original packaging). For example, even a dried spool starts to foam during printing after only 2 hours of an air access. As a result, the retractions stop working because the evaporated moisture constantly pushes the material out of the nozzle. For this reason, it is crucial to always dry the material properly (usually I let it dry for about half a day in a fruit dryer set at 70°C) and then print directly after removing the material from the dryer, otherwise the quality will start to deteriorate again during printing.
