What is the strength of things printed in 3D?

In fact, your printing settings and model slicing settings will also affect the strength of 3D printing. Because general 3D printing needs to strike a balance between model strength and material loss, everyone wants to print a model with a certain firmness with as little material as possible. Print out a model. If the model is set to 100% solid, the model will be very strong, but the consumption of consumables will be very large, so generally everyone will use a dense appearance, while the model is hollow or filled to a certain extent. In short, the higher the filling density inside the model, the higher the strength of the model when the model is printed. For stacked printed things, its strength is anisotropic. According to the design load direction of printed parts, the stacking direction of each layer should also be considered. For example, the most basic thing is to avoid making printed parts bear the shear stress in the stacking direction, because the load of shear stress between planes is relatively small. For printing, filling is one factor of the model, and the property of the material is another factor of the model. To print a durable product, we should not only consider the filling of the model, but also consider the properties of the materials used. Good printed matter should not only have high surface accuracy, but also be durable. Although the filling will have a certain impact on the printing time, weight and printing cost of printed matter, it can make the printed matter more firm. Tip: If the slicing software you use supports honeycomb, it is recommended that you use honeycomb structure as filling (honeycomb has good mechanical properties). For example, if the filling amount of a 3D printer is 0, then what you print is likely to have dents. D represents the size in 3D printing. The printed object prints according to its length, width and height. You have no support in height, just as you build a building without steel bars. Therefore, for printed matter, filling is very important.
