ColorFabb, a company dedicated to the development and manufacture of filaments for FDM 3D printing, stands out for its constant R&D work and for its wide range of filaments, both standard and experimental.
PLA Corkfill is a PLA-based filament filled with cork fibres. PLA (Poly Lactic Acid) is a biodegradable plastic obtained from natural resources such as starch extracted from corn, beet and wheat.
PLA is one of the most widely used materials in 3D printing today due to the fact that it does not give off harmful gases and that it is not necessary to have a 3D printer with a heated bed, which makes it possible to process this material on any FDM 3D printer.
Thanks to its PLA base, the PLA Corkfill filament is very easy to print and does not warp even when printed on an FDM 3D printer without a heated bed.
In addition to PLA, PLA Corkfill includes a percentage of cork fibres in its composition. Cork is the bark of the cork oak, a plant tissue called phelema in botany, which covers the trunk of the tree.
Cork is a material that possesses a set of unique properties:
Thanks to the filling of cork fibres, PLA Corkfill filament has inherited some of the properties of cork. PLA Corkfill filament is lightweight, with a density of 1.18 g/cm3 (lighter than standard PLA), and impact resistant. In addition, the result once printed offers a cork-like aesthetic.
This finish can vary, like most filaments with wood fibres, depending on the printing temperature; different shades can be generated in the same piece by playing with the printing temperature parameter. For more information on this subject, please refer to the following article.
Due to the particle load it contains, it is recommended to use a nozzle of at least 0.5 mm output diameter. However, as it does not contain abrasive particles, it would not be necessary to use a hardened steel nozzle like other filaments with fillers.
Corkfill PLA filament is ideal for 3D printing decorative elements. One of the great advantages of this FDM 3D printing material is that, by its nature, it can hide and smooth layer lines and other possible defects in the part. Thanks to the geometries that can be produced by FDM 3D printing and the various surface finishing possibilities offered by PLA Corkfill, very aesthetic and eye-catching results can be achieved.
Another field of application for this material is architecture. In the field of architecture, scale models are often required for each project. In order to correctly visualise the design, as well as the construction materials, it is important that the model is as faithful as possible to reality. Sometimes it is difficult to find materials that correctly simulate the real thing and that allow a good level of detail and finish.
Undoubtedly, the choice of filament to be used in each project can contribute to a more sustainable future. The use of biodegradable thermoplastics such as PLA or filaments composed of PLA and natural fibres has a lower impact on the environment than other thermoplastics derived from fossil fuels, such as ABS. Furthermore, thanks to filaments such as PLA Corkfill, it is possible to find filaments that realistically simulate the appearance and texture of cork, offering ideal qualities for manufacturing decorative elements or architectural models.

This filament is developed with a PLA base, so its printing is very similar to that of standard PLA.
3D printing with PLA Corkfill filaments is very simple. It is not necessary for the print base to be hot, although if a hot bed is available, it is recommended that it be between 50 - 60 ºC to avoid any small signs of warping.
The adhesion of the first layer is key to obtain an optimal result, so you can use Blue Tape, Buildtak, Magigoo or 3DLac, although it is not essential.
The recommended printing temperature is between 210 and 230 ºC. It should be remembered that by modifying the printing temperature parameters, different colour effects can be achieved on the surface of the 3D printed piece.
In terms of printing speed, PLA Corkfill filaments allow 3D printing at high speeds.
As with PLA 3D printing, when printing PLA Corkfill, the use of the layer fan is recommended.
When printing with filaments with fibres, it is recommended to clean the nozzle immediately after printing, using a cleaning filament such as SmartClean. This will ensure that any residue that might later cause a jam disappears.
