PLA-based filament capable of purifying the air by reducing environmentally harmful particles.

The PLA Purifier is a filament capable of absorbing and purifying the environment, neutralising CO2, NOX and volatile organic compounds (VOCs), converting these harmful particles into harmless mineral gases.

This filament was developed by Recreus, which is a Spanish company dedicated to the 3D printing sector, founded in 2011 and supported by Repsol in order to develop and create new materials for 3D printing such as PP3D.

PLA, polylactic acid, is a biodegradable material obtained from 100% renewable resources, specifically from starch extracted from corn, sugar beet and wheat.

PLA Purifier is a PLA-based filament with a matt and odourless colour to which silicon oxide, aluminium oxide, ferrous oxide, magnesium oxide, calcium oxide and titanium oxide have been added. The addition of these compounds results in a filament capable of purifying the air by reducing environmentally harmful particles and contributing to the reduction of the greenhouse effect.

Recreus PLA is a filament known for the quality it offers. Now with PLA Purifier you can create parts that also purify the air by absorbing CO2 particles, NOx and volatile organic compounds that make up the air and are harmful to health and the environment.

One of the applications in which this filament could be implemented would be in the manufacture of air filters and figures or decorative pieces that require a matt colour.

Thus, with the PLA Purifier we will be able to make parts that help to improve the environment without losing the facilities and qualities provided by Recreus PLA, being able to print on any FDM/FFF 3D printer available on the market, improving the experience in the field of additive manufacturing.

Also, as a new feature, Reciflex and PLA Purifier materials are included in Ultimaker's 'Material Alliance Program'.

You will be able to download the profiles of both materials for the Ultimaker S5 printer from the Marketplace, improving the printing quality of these materials, offering a correct printing from the first time, without complications and making it easier to use.

To download the profiles use this link, or access the Marketplace from the Ultimaker website, and from the 'Materials' section by typing 'Recreus' in the search filter to find both material sheets.

As is well known, 3D printing with PLA is easier than with ABS. Although it is not necessary for the build plate to be hot, it is recommended that it is at a temperature of approximately 40 - 60 °C to ensure good adhesion to the hot bed. Recreus also recommends an extrusion temperature of between 215 - 225 °C together with a speed of between 20 - 100 mm/s.

If the 3D printer has a layer fan, it is recommended that it is active for best results. This is because, depending on the size of the part and the geometry, it may not have enough time to solidify the layer and it may appear to have melted. Nowadays code generators already have a system that slows down and waits for the layer to solidify to avoid this problem.

Adhesion of the first layer of material is critical for good printing results, so it is recommended to use Ziflex, BuildTakMagigoo or 3Dlac to provide optimal adhesion throughout the process, avoiding warping.
It is recommended to lower the fill density to prevent the part from storing too much heat. As for the brim parameter, it is recommended not to use thicknesses greater than 5 mm to prevent the first layer from peeling off.
