The PLA-90 PREMIUM Natural filament is a filament designed for all 3D printing users who wish to obtain advanced properties with a PLA filament. PLA-90 PREMIUM Natural is much less brittle than standard PLA and stands out for its high strength and stiffness. The main advantages of this filament are that it reduces shrinkage to a minimum and that the softening temperature is a little over 90ºC (hence its name).

The main advantages of this filament are minimizing the contraction and softening temperature is a bit higher than 90 °C (hence its name). The latter is the most prominent and well-known advantage of this filament. The standards PLA filaments having a softening temperature (Tg or glass point) of 55 °C; that is, once a piece printed with standard PLA, as is exposed to ambient temperatures of 55 °C decreases the glass temperature and happens to have visco elastic properties. (it starts to be "sticky" or slightly soft losing its mechanical properties).

This usually happens with printed parts PLA when exposed to ambient temperatures in hot weather (in excess of 55 °C), losing the desired properties. In contrast, the ABS has a Tg of 105 °C which makes parts printed with this material are resistant to room temperature, but in return the ABS is more difficult to print because it is necessary to have high temperature hot bed to avoid warping effect.

That is why the Natural PLA-90 PREMIUM emerges, which has a facility similar to printing and PLA also has a softening temperature similar to ABS (above the 90ºC, around 105 ºC). Properties that make it the ideal filament minimizing weaknesses and maximize the strengths of ABS and standard PLA.

Then in the next picture you can see a comparison between the ABS, standard PLA and PLA-90 PREMIUM Natural:

If your printer has a fan nozzle it is recommended that you activate it for best results. If you need to print very thin and tall pieces, you will see that the PLA plastic does not give you enough time to harden each layer, so that the piece will be as if it had melted. To solve this problem we give a very simple advice, it prints at the same time at least two pieces, and place them separate at the base. Thus while the extruder is moved from one piece to another, the plastic has time to harden each layer in achieving a better result.

The adhesion of the first layer is key and probably the most important factors for good prints, so you can use Magigoo, BuildTak, Blue Tape or 3DLac. It is also advisable to set the "raft", which is to create a first thick layer, such as media, who will not suffer that contraction and on which to print the piece. The disadvantage of using the "raft" is that this first layer will have a less smooth. It is advisable to lower the density of "infill" parameter for the part to store less heat. As for the "brim" (the membrane that is created around the piece) parameter is recommended to set it to never greater thicknesses of 5mm to help the first layer will not peel. As for the interior temperature where printed it is recommended to be controlled and no drafts.

If the piece has trouble peel off the glass or printer dock to finish printing a trick widely used it is to introduce the glass along with the piece a few minutes in a refrigerator to make it easier to take off one's own piece of the bonding base.
