Some are designed to be used by professionals that require a bit of expertise on the side of the user such as BricsCAD Pro. There are a variety of 3D modeling software packages available. Of course, it's better if you run some tests as well to determine what the correct fit tolerance is for the 3D printing model that you are creating. Use a 0.4mm offset if you want to create a loose fit like with hinges or box lids. One tip for creating correct fit tolerances is to use a 0.2mm offset if you want to create a tight fit such as connectors. For example, a part may feature several small artifacts on its surface that can affect the fit between pieces.Įxperts recommend that you learn your 3D printer's tolerances to avoid poorly fitting parts. This means that parts should be designed to feature enough space or gaps between them to account for possible deviations in their dimensions.ģD printing is not as precise as other manufacturing methods. If you're designing a model that features interlocking parts, then you need to make sure that you design proper clearances to make sure everything fits just right.

Standard Resin - 1mm, but may increase as the 3D design becomes larger in scale.

Silver - 0.6mm for a gloss finish, 0.8mm for a high gloss finish, 1mm for small 3D models such as ring.

Brass - 0.6mm for a natural finish, 0.8mm for gold and color-plated finishes.

Here is a list of the minimum wall thickness for some of the most popularly used 3D printing materials: Take note that the correct wall thickness of a model will depend on the material and size of the design.

In short, it's important that you ensure that you get the wall thickness just right. If it's too thick, it might cause too much internal stress and result in the model cracking or breaking. But why is this important? When the wall is too thin, it can make your design unprintable or incredibly fragile.

Wall thickness is defined as the distance between one surface of a 3D model and its opposite surface. One of the most common causes of unprintable 3D model designs is wall thickness. Do's of Creating 3D Printing Models Do consider wall thickness

While there is no one-size-fits-all approach that beginners can follow to create a successful design, there are some do's and don'ts that are worth knowing to lower the chances of producing a failed print. Designing a model for 3D printing can seem like a daunting task.
