Build Plate Adhesion Type
What this setting does is help improve different options for extrusion loading and attachment to the build platform. Once set the edge will add a single layer of flat area around the base of the model to prevent curling. The base adds a thick mesh with a top plate under the model, and the skirt is a line printed around the model but not connected to it.
There are three types of print platform attachments: skirt, edge and raft. You can also disable attachment type by setting it to None.
The edge is a single layer of flat area around the base of the model. The purpose is to keep the edge of the print down and allow for a larger contact area between the print and the build plate. • Larger surface area allows your prints to adhere better to the build plate. This is useful for almost any print target larger than a few centimeters.
• This edge also keeps the edge of the print down. Materials that shrink significantly when cooled, such as ABS, tend to deform severely when printed. A brim with sufficient width will prevent this warping by holding the corners in place.
The hem is a single line that goes around your print. It does not contribute directly to establishing plate adhesion. However, if you don't want to use other attachment methods, this method still serves two purposes.
• It causes your nozzle to prime before you start printing the actual model to ensure the material flows correctly.
• It allows you to see if the build plate is leveled correctly.
The base is the thick plate between the model and the build plate. The base protects your prints from the heat of the build platform. It will also have a large surface area to attach to the printing platform. The print target is placed on top of this raft and it will probably stick better. Be careful with thin print targets, though, as it may be difficult to remove the base without damaging the print target.
