Choose the right tolerance when exporting your 3D file In most 3D modeling software, when exporting you will be asked to define the tolerance for the export.

This tolerance is defined as the maximum distance between 3d printer file type original shape and the STL mesh you are exporting.

STL (file format)

It is advised to choose 0. Exporting with a tolerance 3d printer file type than 0. When exporting with a tolerance larger than 0. Of course, some people like the visible triangles if it works as part of their design.

An example can 3d printer file type seen in the wolf ring below, where you can clearly see triangles in both the STL file and the end result. A mesh model, on the other hand, is a collection of small triangles that make up a surface.

If you compare these two types of models to a 2D image file, a parametric model is like a vector file. DXF while a mesh model is most similar to a pixel image.

Just as a pixel image. PNG approximates a vector file. Ultimately these machines require a series of closed 2D contours that are filled in with solidified material as the layers are fused together.

A natural file format for such a machine would be a series of closed polygons corresponding to different Z-values. However, since it is 3d printer file type to vary the layer thicknesses for a faster though less precise build, it was easier to define the model to be built as a closed polyhedron that can be sliced at the necessary horizontal levels.


The STL file format appears capable of defining a polyhedron with any polygonal facet, but in practice it is only ever 3d printer file type for triangles, which means that much of the syntax of the ASCII protocol is superfluous.

To properly form a 3D volume, the surface represented by any STL files must be closed and connected, where every edge 3d printer file type part of exactly two triangles, and not self-intersecting. Since the STL syntax does not enforce this property, it can be ignored for applications where the closedness does not matter.

STL (file format) - Wikipedia

The closedness only matters insofar as the software that slices the triangles requires it to ensure that the resulting 2D polygons are closed. Sometimes such software can 3d printer file type written to clean up small discrepancies by moving vertices that are close together so that they coincide.

The results are not predictable, but it is often sufficient. Consequently, many computer-aided design systems can output the STL file format.

What is the standard file format for 3D printers? - Quora

In most cases, it is useful to implement a Boolean operation, which is a function that helps to merge several overlapping elements. A reversed face or inverted normal means that the surface of your model is facing in the wrong direction: Grouped Models Unfortunately, so-called grouped models are a common reason for us to cancel orders.

For example, users that upload the following design with six separate shells will get a notification that their order will be cancelled 3d printer file type course they will 3d printer file type fully reimbursed.
