The purefil refill packs are wound filaments that are supplied without a spool. With this product, the purefil plastic spools can be refilled with new filament. This means that the empty spool no longer has to be disposed of and resources are saved.
The use of high-quality raw materials creates a 3D printer filament that is particularly easy to process. Using a state-of-the-art manufacturing process, very low manufacturing tolerances are achieved, which leads to convincing printing results with all FDM 3D printers. Each coil is sealed in a high-quality bag.
- Made in Switzerland
- small diameter and roundness tolerances
- easy to print
In general, one can say that PET-G is characterized by clarity/transparency, odor neutrality and robustness.
Nevertheless, PET-G is very easy to print and there are no significant problem areas. These properties, together with high impact strength, excellent flexibility and shrinkage values close to zero, make PET-G an excellent material for FDM 3D printing.
Only before processing there is one very important point to consider. PET-G must be well pre-dried to prevent the material from forming bubbles and decomposing during processing. This fact also affects the storage of already used filament rolls. These must be stored in a dry and airtight manner (already humidity can severely deteriorate the filament). It is advisable to add small drying bags (silica) to the packaged roll. If it is noticed during processing that the filament is «damp», it can be dried in the oven at 80°C for 2h-4h. This filament meets the compositional requirements of European Regulation No. 10/2011 on plastic materials intended for food contact.
