With the appropriate adjustment of the above parameters you get the ideal retraction for your 3D printer. If you need to use this parameter, we recommend using the same distance as the layer height. This elevation is only necessary in the case of making pieces with many details and with small areas of great detail to avoid leaving traces of material right in that area. Z-axis elevation when retracted (Lift z): At the same time that the retraction occurs, the HotEnd moves on the z axis the indicated distance.

With this material remains are avoided in the faces seen from internal parts of the pieces. Enable combining: By activating this parameter, which is in the section of advanced options of retraction of the program of lamination that is used ( Cura, Simplif圓D, Slicer, etc), apart from performing the retraction, the HotEnd is prevented from moving over holes.Minimum displacement : Minimum length from which you want the retraction to take place.Retraction speed: Speed at which the extruder motor drives back the filament. With this parameter it's necessary to be very careful if high speeds are used (greater than 70mm/s) because it can mark the filament in such a way that it's unusable to continue the 3D printing.It varies depending on the type of material, the type of extrusion system ( Direct or Bowden) and the type of HotEnd. For flexible materials, especially for the TPE type ( Filaflex), retraction must be deactivated to prevent the filament from coiling on the extruder pinion. Retraction distance : Length of material that recedes in the retraction process.

The parameters that configure the retraction are: Retraction is the recoil movement of the filament necessary to prevent dripping of material during movements and displacements that the vacuum extruder performs during 3D printing. This article tries to clarify the concept of retraction in 3D printing as it's a very important parameter to achieve quality prints, without material depositions on the exterior face of the model, or threads between pieces that are printed at the same time.
