Why Does Wall Thickness Matter In 3D Printing?
For a model to 3D print successfully, each part of your model should have the minimum
wall thickness required for the material, printing process and scale of that model.
Certain 3D Printing technologies can make 0.4mm walls for instance. Any thinner walls
in your model will cause the print to fail. If you switch material or sometimes even
another 3D Printer using the same 3D Printing process a 0.4mm wall that used to print
will now fail. If you make a thin figurine measuring 5 CM then a 0.4mm wall could keep
that figurine upright.
Meanwhile if you now want to 3D Print the same model at 30 CM it might become too fragile or fail. In each of these cases you will want to adjust and increase the wall thickness. In some other cases you may want to reduce wall thickness to save on material cost or make an item more elegant. Or you may want to make a clear material more transparent by reducing the wall thickness. Our intelligent wall thickness adjustment tools will let you change wall thicknesses at will automatically to suit different 3D Printing processes or scales.
What is the problem with bad wall thickness?
What's cumbersome is that not all 3D models were designed for 3D printing, and could
have areas that are thinner than what your 3D printer and material can actually print.
If you attempt to print a 3D model with thin areas, it could be problematic as it could
lead to unprinted areas of your model or your model falling apart due to gravity or
other forces. This could disfigure your model causing an unsuccessful result with your
Another problem with thin areas is if you order a print through a print shop or service bureau, they usually have the tendency to over thicken your model to ensure print succes.. This is done to reduce their print failure rates and to minimize the chance of the model breaking while being shipped. This may needlessly increase your costs or may not be the aesthetic result that you want.

What are the most common parts that need thickening?
Wall thickness can apply to areas in models that are very thin. These include hair,
fingers, capes, clothes, nose, ears, weapons, gears, and other thin areas.
