Refill Easy PETG is a material developed by the renowned filament manufacturer Fiberlogy, which offers filaments with exceptional quality, perfect for a multitude of applications in various industries.

Refill Easy PETG is a thermoplastic copolyester (extruded polyethylene terephthalate glycol copolyester). Unlike PET filaments, it does not crystallise when heated, so it is very tough and flexible, in addition to its well-known chemical resistance (it is resistant to water, acids, alkalis and alcohols).

Refill Easy PETG filament is a modified version of the simpler PET; it is a non-toxic thermoplastic polymer used in the manufacture of clothing and products such as containers.

Refill Easy PETG is a high quality PETG filament. PETG filaments are gaining a lot of popularity due to its low melting temperature and durability, making it a good alternative to any ABS or Nylon. This filament is very useful for the production of final parts or functional prototypes.

Refill Easy PETG exhibits many properties similar to those of a PLA filament. On a mechanical level, PETG has better properties. In terms of thermal resistance, PETG achieves a lower value than ABS, but higher than the vast majority of PLA.

Properties of Refill PETG

Refill Easy PETG has a high adhesion to the base and adhesion between layers, so warping effect is practically nil.

Among the different Refill Easy PETG colours available are some translucent colours, which can be used to produce translucent parts, especially when printing parts with low wall thicknesses.

Refill Easy PETG is presented on a filament reel without a spool, i.e. its format is masterspool. This format requires the use of a spool holder. It is possible to download models of detachable spools ready for 3D printing, but sometimes these detachable spools do not adapt well to the dimensions of the masterspool. In these cases, it is very useful to use a variable sized spool holder that automatically adjusts to the inside diameter of the masterspool. For instructions on how to use the variable sized spool holder, please refer to the section "Tips for use".

Fiberlogy is one of the manufacturers to include this format in its range of materials. Its quality and applications are identical to those of the Easy PETG filament with a spool. The only difference is that the refill does not have a spool, thus saving resources and reducing the environmental impact.

When using the variable spool holder, the following guidelines should be observed:

The variable spool holder works very simply. Simply compress the product directly with your hands, insert it inside the masterspool and release it so that it returns to its original shape.
Then take one end of the filament and place it in the clamping slot. In this way, the start of the masterspool will be fixed. These slots are also used to hold the end of the filament each time a print is completed, thus avoiding possible overlapping of the filament.

To ensure optimal print quality, it is necessary to select the appropriate settings for each 3D printer, considering the printing conditions. The recommended printing temperature ranges between 220 and 250 ºC, and the best bed temperature is 90 ºC (Kapton tape on glass). The layer fan should be set between 0 and 25%, and the flow rate between 95 and 105%. The recommended print speed is < 100 mm/s. The ideal retraction speed is between 20 and 45 mm/s, with 2 to 3 mm retraction for direct extrusion and 3 to 5 mm retraction for Bowden.

Proper storage of Easy PETG filament is essential, as processing damp filament can lead to polymer chain degradation, fragility, poor layer adhesion, stringing, and oozing. It's best to store the filament in a sealed bag with desiccant or in a vacuum-sealed filament container. If the filament absorbs excess moisture, it should be dried in a filament dryer at 60 ºC for 4 hours before it can be extruded.
