Printing In 3d: 5 Important Factors To Be Consider
There are many important elements to take into consideration when thinking about additive manufacturing. The five fundamental elements listed below are essential to ensure that your product is designed in a balanced way. Your product will be useful and beautiful if it is properly balanced in size, resolution, thickness as well as orientation and the material you choose.

Size
When designing an item the first thing you need to be aware of is the size. Every technology has its own ideal design, and some are bigger while others are smaller.
FDM machines can produce parts up to 16″×14″×16″. If your item is larger than that, it may be divided prior to fabrication and then joined professionally.
The size of your pieces can affect the time it takes to build. Larger parts are more difficult to make and require more materials. This can lead to cost increases.
The resolution
The resolution refers to the thickness of each layer being used for additive manufacturing. Depending on the process used to make the part, a thinner layer may lessen ridges, imperfections or imperfections. High resolution may provide a smoother surface and better surfaces for post-processing. The less layers there are and the more distinct the details, and the more manufacturing time.
If you want an object that has very high resolution, you should choose SLA (Stereolitography) technology that has an average thickness of up to 25 microns (0.025mm). SLS technology provides very high resolution. 100 microns (0.1mm). FDM layers are generally 250 microns thick (0.25mm) however, we also provide high-resolution (0.175mm). You can print with a lower resolution (330 microns or 0.330mm). This is an excellent alternative for large, less aesthetic objects that can be produced quickly and at lower costs.
Wall thickness
The fundamental characteristic of your design is the wall thickness. This will ensure stability, precision, and tolerance in additive manufacturing components. A thinner wall thickness will reduce the construction time. However, too thin components may have less precise characteristics and may be more fragile.
The thin parts made with SLS are more likely to be warped due to the the manufacturing process. Pieces made by the SLS method are susceptible to high temperatures, as well as the amount of powder used in production. SLS material may shrink when it cools or solidifies. With a thickness of between 1mm and 3mm, a geometric stability is much more easily achieved. You can still achieve the minimum thickness of 0.4mm. However, this is more dangerous.
FDM is one of the materials in which the recommended minimum thickness is 1.6mm
The orientation
The orientation of an object in 3D printing is determined by its placement on the printer’s platform. It is possible to place it vertically, horizontallyor at an angle or flat. Orienting the components correctly to fabricate is an essential step that affects the quality of the finished product, particularly when it comes to dimensions and tolerances to errors. These elements directly affect the energy required and the amount of support structures that are required. These factors all contribute to the total price of the piece.
The orientation can also change based on the method of printing used. FDM prints have a high elastic force in the X-Y direction but a weaker Z direction due to how the layers were created. This can result in visible lines between layers, which may affect the look of your components. Certain orientations are better for curving shapes. In some instances, the orientations will be more effective in the event that they are overhanging the surface, which requires more support.
If you don’t specify other than that, we will make sure that your parts are placed in a way that will maximize the strength of their surface and their quality.
The material selection
There are many materials that you can select from based on the method you choose to print your 3D model. The constraints of your component will dictate the type of material you choose. It is crucial to select the appropriate material for your piece. For instance, if the part will be subjected to very extreme temperatures or chemical solvents, you should think about ULTEM (in FDM technology). If you need it to be impact resistant then polycarbonate is an ideal choice.
SLA technology offers several interesting resins that can be utilized in a variety of applications. Flexible resin is a material with the same properties as rubber. Castable wax resin can be found if you are looking to create a lost wax casting. In contrast, if you just need to keep the object available for usage, ABS (FDM), Nylon (SLS) and acrylic resin (SLA) can do excellently at a cost that is reasonable.
Design balance
A creation specifically for 3d printing is dependent on the resolution, size as well as the thickness and orientation of the material. These elements must all be considered and balanced so that you get the functional part you require.
