3D printing model requirements for the model:
1. The object must have thickness
In various types of software, the curved surface is very ideal, but there is no wall thickness, but in reality there is no object without wall thickness, so you can’t just use a few simple curved surfaces when modeling. Into an unclosed model.
2. The object must be closed
The closed definition means no water leakage. In many cases, it is very difficult to check whether the model has such a problem. At this time, you can check with some software, such as the STL detection function of 3DS MAX.
3. The direction of the normal should be accurate
The normals of all faces in the model need to ensure the accuracy of the direction. If the direction is found to be wrong in the model, it is impossible to judge whether it is the inside or the inside of the model when the model is printed in 3D.
4.The object model must be a manifold
If there are multiple faces sharing an edge in a grid data, it is a non-manifold.
5.Delete redundant geometric shapes and patches
When modeling, some reference lines, points, and surfaces, including some hidden geometric shapes, need to be deleted if they are not deleted when the modeling is completed.
When two faces are superimposed on each other during modeling, a duplicate face will be generated, and this duplicate face needs to be deleted here.
6.The minimum thickness of the model
The nozzle diameter of the printer is fixed. The wall thickness of the printed model can take into account the minimum wall thickness that the printer can print, otherwise there will be a failure or wrong model. Normally the minimum thickness is 0.8 mm. You can use different 3D printers. Changes.
