Most 3D printing processes are actually 2.5D. What does it mean? The conventional process of 3D printing is laying material on top of each other on the parallel plane, resulting in a three-dimensional object.
In traditional 3D printers, moving parts are most often either the printing table, or the printing head, or both of them, such as in the Composer — continuous fiber 3D printer. Even though the table and the print head move along the x, y, z axes, the layers are still stacking in the parallel plane, and each subsequent layer is parallel to the previous one.
Both FFF (plastic) and continuous fiber 3D printing have a number of limitations. The restrictions are that it is not possible to reinforce parts in two planes at the same time. Since the layers are stacked parallel to each other, the part can only be reinforced in the same plane. …
The previous word was about the first pillar anisoprinting is based on, this word will tell about the second one — fiber steering.
The fiber steering is the ability to control the trajectories of reinforcement. It is one of the biggest advantages of continuous fiber 3D printing technology. This allows you to produce optimal composites for a given load without increasing the weight, wich impossible with conventional composite manufacturing technologies such as composite layup or winding.
For example, you can effectively reinforce the parts with holes. It’s well known that holes are stress concentrators that significantly reduce the strength of structural elements. …
In the previous word, we figured out that all composites are anisotropic and anisotropy can be an advantage if it is used correctly. What does it mean? Read below.
The most optimal shape for continuous fiber reinforced composites is the lattice structure.
Lattice structures allow using the amount of material that is exactly required for bearing expected load. Therefore you get a huge advantage in terms of weight, production time, and the final price of the part.
Reinforcing with composite lattice structures allowed to decrease the mass of payload adapter up to 60% and increase the ultimate strength up to 33%. …
