Thermoactive PLA

When printing with Thermoactive PLA, it is recommended to take into account the following aspects:

For 3D printing with Thermoactive PLA, it is not necessary that the printing base is hot although, if possible, it is recommended that the base be at approximately 45ºC, to avoid the appearance of any small indication of warping.

The recommended extrusion temperature for this material is between 190 ºC and 220 ºC depending on the printer used, and it is recommended to print at a speed of between 40 and 110 mm / s. The article on our 3D printing blog explains about the main questions of 3D printing in PLA and ABS.

If your printer has a layer fan, it is recommended that you turn it on for best results. If you need to print very thin and tall pieces, you will see that PLA plastic does not give enough time to harden in each layer, so the piece will look as if it has melted. To solve this problem we give you a very simple tip, print at least 2 pieces at the same time, and place them separately on the base. In this way, while the extruder moves from one part to another, the plastic has time to harden in each layer, achieving a much better result.

Adhesion of the first coat is key and probably one of the most important factors in obtaining good impressions. so you can use Blue Tape, BuildTak, Magigoo or 3DLac.

It is also recommended to configure the "raft", which consists of creating a first thick layer, like supports, that will not suffer this contraction and on which the piece will be printed. The downside to using the raft is that this first coat will look less smooth.
It is recommended to lower the density of the “infill” parameter so that the piece stores less heat. As for the parameter "brim" (the membrane that is created around the piece) it is recommended to adjust it in thicknesses never greater than 5mm to help the first layer not peel off.

As for the temperature of the interior where it is going to print, it is recommended that it be controlled and that there are no drafts.

Regarding printed parts, it should be noted that, due to the softening temperature of PLA, from 55-60 ºC the material itself softens, so it's not recommended to expose printed parts to these temperatures.

We recommend confirming the results and final properties with own tests. For more information you should consult the technical data sheet of the product.
