This is a flexible filament with properties durable rubber.

The Soft-Flexible PLA filament is a flexible filament with durable rubber properties. It is useful for making parts that need to be flexible, not to break when bent (resistant) and also to be durable.

Standard PLA (polylactic acid) is a biodegradable plastic obtained from natural resources, in particular from starch extracted from corn, beet and wheat. This material is one of the most widely used materials in 3D printing today because it does not give off harmful gases and is easy to print on. The ease of use of this material derives from different factors:

  1. It does not require a warm bed, although if available, it is recommended to use it at about 60 ºC.
  2. It is generally printed at low temperatures (between 190ºC and 220ºC).
  3. It is a material with almost no warping (warping is the deformation of the pieces with respect to the base).

Standard PLA is very rigid and does not bend well, while Soft-Flexible PLA is flexible; its texture is reminiscent of rubber and has a Shore hardness of 92A. It is an impact resistant material and suitable for many industrial and domestic applications such as: tyre, machine parts - mechanical elements that must withstand force - or children's toys.

Soft-Flexible PLA is one of the most widely used materials for flexible parts. The main difference between Soft-Flexible PLA and other flexible filaments is its known strength and durability, as well as the ease of printing even with Bowden-type extrusion systems. Soft-Flexible PLA is printed in a similar way to standard PLA, although it must be printed at a lower speed than using standard PLA to obtain good results; as well as using a higher bed temperature.

Table 1: Comparison of properties of the flexible filament range

Like standard PLA, Soft-Flexible PLA filament is a bioplastic made from renewable resources such as corn. It is a biodegradable material and its carbon footprint is much smaller than that of other traditional 3D printing materials.

In addition, Soft-Flexible PLA does not contain any hazardous chemicals. It is a material suitable for human skin contact and food contact; meeting all the requirements of the European Union Regulation on Food Contact and the US Food and Drug Administration (FDA). In addition, this filament is RoHs certified and Reach compliant.

The principal difference with the standard print PLA filament is that needs more bed temperature (about 100C) and printing speed should be lower (range of 10mm/s to 30mm/s).

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, printed at the same time at least 2 pieces, and place them in separate 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.

It is always advisable to use Magigoo, BuildTakKapton TapeDimaFix or 3DLac. It's also advisable to set the "raft"which is to create a first thick layer, and supports that will not suffer that contraction and on which is printed 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 part) parameter is recommended never fit in greater thicknesses of 5mm to help the first layer does not come off. As for the interior temperature where printed is recommended to be controlled and no drafts.
