For the bottom layers the important factor to consider is how the surface will look should there be a mistake whilst laying down the first layer, and for this reason it is recommended to have at least two bottom layers.Ī similar consideration is required for the top layers. The upper and lowermost layers that sandwich the model are filled with a Solid layers pattern. Unless the model requires single width walls it is generally recommended to have a minimum of two perimeters as this gives some insurance that if a section of the perimeter is not printed correctly then the second perimeter will help cover it. Perimeters defines the minimum number of vertical shells (i.e. A later goal will be to strike a balance between layer height, the speed of the printer, and the quality of the resulting print. Print speed - Shorter layers will result in smoother prints but each print will take longer, simply because the extruder must trace the pattern more times. Aesthetics plays a role here, but also the type of model, for example, a mechanical part may not need such a high resolution finish, whereas a presentation piece may do so. There are several factors that influence how high each layer should be:ĭesired resolution - Lower layer height should result in prints with less noticeable ribs or bands, as each layer is smaller. Layer height is the thickness of each layer, and it is the step along the vertical axis taken before extruding a new layer atop the previous one. You (or rather your slicer software) needs to know what unit value was used during export in order to import the model at proper scale.Print Settings: Layers and Perimeters General. This isn’t a problem with the STL or model it just reflects a different unit size assumption on import than was used during export and is an inherent limitation of the STL format (i.e., no unit specification in the STL). The same is true with other slicers if they assume a particular unit value, then STL files that were exported using some other unit value will be scaled incorrectly upon import.

If it was designed/exported to STL as Inches, then it will be TINY (1/25.4th scale) when imported to Cura (and scaling xyz up by 25.4 will fix that). Cura assumes (and assigns) millimeters on import, so if the file was designed/exported to STL as mm as yours was, then it will scale correctly when imported to Cura. The software importing the file has to assign a value to those units. The STL file’s internal structure contains units, but not a unit size. So is there any way I can normalize or ensure that this scale is right across all or most 3d printing software? I know blender uses blender units. It seems like my cura gets the scale right as well as ScottW’s. The last issue, the seemingly incorrect scale of the STL.
