The first and easiest option is to let the Simplif圓D Software fix these problems during the G-Code preparation phase. Now that you know where the problem is, there are several options you can use to repair the mesh. This is another very useful way to look inside your part for any potential issues. Select the Z-Axis for the slice axis and put the slice plane at 10mm. It is important to recognize that the problem areas may actually be internal to your model and may not be visible from the outside. At this point you should notice a third problem area that is actually inside the body of the pyramid. There are also a few faces on the top structure that do not meet up cleanly and are also causing problems. You will notice that the underside of these features have several holes and are not watertight.

If you zoom in on the decorations at the base of the large staircase, you will see several red lines in this area. If there are a large number of holes or self-intersecting surfaces, it becomes more difficult to determine what part of the model is actually intended to be solid. This will create holes in the exterior of our part that can be very confusing to the software. These represent triangles that do not match up cleanly to another surface. If you run the non-manifold edges check for the pyramid model, you will notice that several edges on the model have been highlighted. This will visually highlight any problematic edges on your mesh with a bright red line. This will look through your model for any holes or areas that are not watertight. There are two very useful tools in the software to help you locate any potential problems within the mesh. So once we think there might be a problem, how do we identify what feature of the mesh is causing it?
For example, a hollow cutout might appear as a solid filled in layer, or vice-versa. If the visual preview looks different than the model you expected to create, there might be problems with the mesh. You can preview one of these files at any time by pressing the large Prepare to Print! After the preview is loaded, you can even animate the build which will play a video of your nozzle moving around on the screen laying down each individual strand of plastic. In addition to creating these files, the software also has the ability to render a visual preview of these instructions, showing you exactly how your printer will interpret the commands. These instructions may be plain text such as the common.

When you are ready to fabricate one of your digital models, the software will create a long list of instructions that tell your printer how to actually create the part. In this tutorial we are going to talk about self-intersecting surfaces, missing triangles that create holes in the surface of your mesh, backwards triangles, and even duplicate surfaces. These triangles fit together to define the overall shape of your geometry and they are the basis for the STL and OBJ file formats.Įach triangle is represented by 3 edges along with a normal vector from the center of the triangle that defines which side of the triangle is outward facing. Digital models on your computer are typically represented by a large list of triangles. This tutorial will teach you about common mesh errors that you may encounter with your 3D printer.
