BASIC MISTAKES AVOIDED IN MAKING OF 3D MODELS
Overlooking Wall Thickness
Problems linked to wall thickness are by far the most common reasons why some 3D models are not printable. In some cases, wall thickness is too thin. Walls that are too thin make small parts on the model unable to be printed or very brittle and could break off easily. In other cases, walls that are too dense to generate too much internal stress and could cause the item to crack or even break.
Keeping the right space between your moving parts
With some materials its possible to print interlinking, interlocking, moving parts and shell patterns. Once again this is not possible with every 3D printing technology. Also to reduce the risk of distortion and to save money, it makes sense to hollow out your 3D model and add leak holes to your 3D print. Free 3D modeling software Mesh mixer makes this quite easy.
Overlooking materials guidelines
Following to the design rules of the material is essential for a successful print. Ideally one should read the design guides before one starts to work for model. One can find the design guides for all of the materials on internet.
Overlooking file resolution
Low-resolution STL file: It’s important to be aware that a poor-quality export will never allow us to provide with a good print. Low-resolution means that the triangles in your STL file are large and the surface of print will not be smooth. It will lead to a somewhat “pixelated” print.
Very high-resolution STL file: A file with a resolution that is too high will make file too big and sometimes awkward for us to handle. It might also contain an extreme level of detail that the 3D printers simply cannot print.
