Five Important Aspects To Be Considered When Printing 3d
If you're thinking about additive manufacturing there are several important elements to consider regarding the design of the 3D elements. These five essential elements must be considered to ensure the product you create is constructed in a balanced way. The harmony between size, resolution the thickness, orientation, and material selection will ensure the purpose as well as the aesthetics of your creation.

Size
When you are creating an item one thing to consider is the size. Each technology has its ideal size, but some are bigger than others.
FDM machines can make parts as large as 16"x14"x16". If your piece is bigger than that, it could be divided prior to fabrication and then glued together professionally.
Your pieces' size can affect the duration it takes to make them. Larger pieces take longer to construct and will need more materials, which results in higher costs.
The resolution
In additive manufacturing the resolution refers to the thickness of each layer of material that is applied. Depending on the technology employed in the process of making the component the thinner layer can reduce imperfections or ridges. High resolution can provide smoother surfaces and more surfaces for post-processing. The time to manufacture is longer if the layers are thinner.
For an object with very high resolution, you should choose SLA (Stereolitography) technology with a layer thickness of up to 25 microns (0.025mm). SLS technology offers extremely high resolution. 100 microns (0.1mm). The typical FDM layer thickness is 250 microns (0.25mm) and we offer high resolution (0.175mm). It is possible to print at the lower resolution (330 microns or 0.330mm). This is an excellent alternative for large and less attractive objects that are produced quickly and at lower costs.
Wall thickness
The thickness of the component's walls is a fundamental characteristic of your design , which guarantees accuracy, stability and precision in an additive-produced part. A thinner wall thickness will reduce the manufacturing time. However, too thin components may have less specific characteristics and could be more fragile.
SLS makes it more likely that the parts that are thin can warp as a result of the process of manufacturing. SLS components are exposed to extreme temperatures as well as the weight of the powder is increased during the process of manufacturing. SLS material can shrink when it cools or solidifies. These characteristics are more stable when the thickness is between 1mm and 3mm. It's still possible to achieve the minimum thickness of 0.4mm. But, this is more dangerous.
FDM is an example of a material with a minimum thickness that is 1.6mm
The orientation
In 3D printing the orientation is the way that the object is placed on the print platform. You can place it vertically, horizontallyor at an angle or flat. The final quality of the component manufacturing process is influenced by the direction of the component. This is especially true in the case of error tolerance and geometric dimension. The amount of energy required and the amount of support structures required are also directly affected. These factors all contribute to the overall cost of the component.
Depending on the technology used, orientation may vary. FDM prints are characterized by a strong elastic force in the X-Y direction, however, they have a lower Z direction due to the way the layers were printed. This can result in obvious lines in between layers, which can affect the aesthetics of your parts. This is why certain orientations are recommended for curves. In some cases, the most effective orientations are when they extend over the surface, thus requiring more support.
We will ensure that you position your parts so that they have the best ratio between surface quality and strength of the part (unless stated otherwise).
Material selection
Depending on the technique you choose depending on the method you choose, there are various materials to chose for the 3D printing. The requirements of your part will dictate the type of material you select. If your part must have particular resistances, it is essential to be careful when selecting the material. For example, if it is going to be exposed to extremely high temperatures or chemical solvents, you should look into ULTEM (in FDM technology). Polycarbonate is a good option if it must be resistant to impact.
SLA technology offers several interesting resins that are suitable for use in various ways. If you want a material that has properties similar to rubber, try selecting the flexible resin. Castable wax resin can be found if you are looking to make a lost-wax casting. ABS (FDM) as well as nylon (SLS) and acrylic resin (SLA) are all able to work well for you.
Layout stability
A product that is specifically for 3d printing is contingent on the size, resolution, thickness and the orientation of the material. When these factors are all considered and balanced, you are sure to get a functional component that is able to meet your needs.
