ZERO-WARP PLA (PLA-45) filament is designed for all users who want to make 3D printing large pieces that could pose filament warping effect. PLA filament ZERO WARP is currently existing filament that has less warping effect.
Warping effect (contraction) is that especially in large pieces are usually off the corners of the bed parts print due to contraction of the printed material itself due to the plastic exits the extruder at a high temperature and when cooling (after leaving the extruder) shrinks and make this problematic effect. That is why in all the plastic filaments always be to use warm bed (at different temperatures) to temperature change abrupt least possible. This problematic effect is minimized to the maximum with the help of the BuildTak, 3Dlac or Kapton Tape.
Although the standard PLA is one of the materials has less warping effect is always susceptible to this effect appears, especially in large pieces. So it is always advisable to print with a base temperature of 50 ° C, but can be printed with the base at room temperature without problems using or 3DLac Blue Tape.
With this filament there is virtually no contraction (without warping effect). The softening temperature is similar to a standard PLA as it is in the 45 °C. If you want to make a piece with a PLA filament that resists further softening temperature then you must use the PLA-90 supports up to 105ºC like the ABS itself.
In terms of flexibility PLA-ZERO WARP is a hard material such as ABS but slightly more flexible than the standard PLA. This is a material of high strength and stiffness.
Then in the next picture you can see a comparison between the ABS, standard PLA and ZERO WARP PLA (PLA-45):
