When creating models for 3d printing, it is important to understand that objects in the real world must have volume. But you will eventually have to Object > Convert to > Mesh from Curve/Meta/Surf/Text before exporting to your slicer. You can create and work with any type of object you want, curve, nurbes, text, etc. Only “Meshes” can be exported to an “.stl” file. Instead, you must “Select” vertices and manipulate the selected vertices through operations such as Grab, Scale, Rotate, etc. Therefore, you cannot just “resize” what you added as a circle to 20mm, or a cube to 20x30x10. Instead, blender just treats them as a bunch of vertices. in blender, you can adjust the initial parameters such as radius and number of vertices, howevever, once you move on to the next operation, those vertices lose their association with the “shape” that we humans recognize. If you’re coming from another graphics program like inkscape, yo may be surprised to find out that blender objects do not retain their shape association. In the case of 3d printing, I find a “Clip Start” of 1mm, and a Clip “End” of 1000mm (1Meter) works well. It is helpful to set the viewing clip space to the scale we’re working with. In most cases you can just choose a format and press export.When zooming in and out to inspect your model, it may disappear from your view. The default directory "//" represents the current blend file path. The file is exported to the directory and the file-name is based on the object name. This section is included for convenience so you can store an output directory for your model and export it without having to go to the file selector each time. Note, for these options you may want to set the scene units to metric/imperial, so you can enter values in cm³ (cubic centimeters) or "³ (cubic inches). Length: This scales an object (or selected objects), to target a maximum length.Useful if you are paying based on volume or want to limit the amount of material used per item. Volume: This scales an object (or selected objects), to target a set volume.There are two tools for scaling, before printing you may want to scale the model based on volume or size constraints. This tool triangulated distorted faces based on an angle limit. but when they are not flat the resulting triangulation is undefined. Distorted Faces Using ngons and quads is fine in most cases.
This is a physical limitation which varies depending on the material and the printer but 45 degrees is a common default.Īll This is simply a convenience function which runs all checks at once.Ĭlean Isolated Removes isolated faces, edges and vertices since these won't be printed and may confuse other tools. When printing without support material, there is a limit to the extent to which faces can overhang. This check is important because other tools rely on the mesh being solid.Įxample of overhanging faces that exceed 45 degrees. Solid This checks that the mesh has an inside/outside (is manifold), and connected faces are not flipped in opposing directions. While the following checks can be done in both object-mode and edit-mode, notice that switching to edit-mode turns the reports into buttons you can click on to select the problem areas. Reported area is given in blender units and squared centimeters (cm²). Area This simply reports the combined area of all faces (with modifiers and transformation applied). note: the method used relies on face normals being flipped correctly and the mesh being manifold. Reported volume is given in blender units and cubic centimeters (cm³) which is a common unit used in 3d printing. Statistics Volume The volume of the mesh (with modifiers and transformation applied). This means it has an inside/outside with no holes. Some of the tools included in this addon (and 3d printing in general) expects geometry to be manifold.The purpose of this addon is to be a collection of useful tools when printing.Ĭurrently there are 5 main sections to this addon which can be accessed from the toolbox.
