As for resin 3D printing, it’s better to go quite fine with minimum wall thicknesses of 2 mm.įor adjusting the right wall thickness, you may notice that some software such as CHITUBOX will be helpful. The minimum wall thickness refers to the minimum thickness that your model should have for any given material or technology.

Left: 5mm wall thickness Right: 2mm wall thickness The minimum cross sectional wall thickness on any part is very much dependent on the overall part size and design. When the wall thickness is too thin, you may encounter problems and issues relating to 3d design and quality. Never mind! There are still some general principles about wall thickness to follow. A same wall thickness for different resins like rigid resin and flexible resin may result in different print quality.īesides, wall thickness of a 3D model may depend on more factors including model size and overall design of the 3D part. So there is no a single, “one-size-fits-all” wall thickness to recommend for each and every 3D printing material. Wall thickness is very important when 3D printing as thin walls or zero thickness walls will cause the print to fail because of its fragility.Įvery 3D printing material has different characteristics. Wall thickness is the distance between the outer surface of your model and the opposite inner surface. You need to know how thick the wall of your objects is supposed to be and guarantee that your model is thick enough before printing. Is your wall thickness enough for a hollow resin model? When it comes to wall thickness, it is important to understand it so that you can print 3D objects successfully. Creating a hollow model means that you need to design your object with “walls”. If you wanted to save material and money, you may hollow the models out so as to reduce the volume of your models.
