Four common misconceptions about designing 3D models

In the design of a 3D model, we use different design software, not only may use different materials, are more likely to use different 3D printer, so in the design of a 3D model, we can easily because of not comprehensive, and into some common mistakes, and make our design more difficult.

1.ignore material characteristics

Different 3D printing materials have different characteristics, some are fragile, some are strong, some are malleable, some are rough, others are high density, others are low density and so on. This means that a model should first consider the material to be used at the beginning of its design. For example, if you want to print the 3D model with ceramic powder, consider the characteristics of the ceramic powder material, and then consider the design of the model, such as how to handle the dangling parts and how to handle the corners.


What material is used directly determines the principles to be followed in the design of the model


2. ignore the wall thickness

So far, the main reason why many 3D design models cannot be successfully printed are related to wall thickness settings. If the wall thickness is too thin, the small part of the model can not be printed out, or it is fragile and can be easily broken.

The correct wall thickness setting is critical for successful 3D printing


3.ignore the STL file resolution

For 3D printing (, the most common file format is STL (standard triangular language), which means that your 3D model can be translated into multiple triangles in 3D space. Most 3D model software supports converting the model to STL format and sets it to the desired resolution. The following figure shows files of different resolutions, from very high resolution (left) to very low resolution (right):

Choosing the right file resolution is important for printing quality
Low resolution STL format file: a low quality file output will never guarantee a good model. Low resolution means that the triangle in the STL file is too large, and the surface of the model is not smooth, which will lead to mosaic printing to a certain extent.

Very high resolution STL format files: files with high resolution can make files too large and sometimes inconvenient to operate. It is likely that many details of the model can not be properly restored, and that is why we recommend that we try to ensure that the STL files are below 100MB.


4. ignore the rules of software usage

Different software has different usage rules, such as wall thickness settings, which are automatically set up in some software, but in some other software, you have to manually set them up.

Even with a zero based novice portal software, there may still be some difficulties in designing a hollow model.

Different model design software has different settings

At present, there are many 3D model design software for different fields, such as Blender, which is suitable for 3D map or animation. Sketchup is popular in architecture field, or it is suitable for creative and creative Zbrush software. You need to make some preparations based on different software, such as whether the model is watertight, whether the wall thickness is moderate, and how to set the print size, etc..

The rules above seem complicated, but you’ll be much more handy when designing the model after you’ve really mastered it.

Of course, you can also contact the professional 3D print model design platform, which can provide you with professional, convenient and efficient 3D printing model design services.
