There are several important aspects to be aware of when you are considering additive manufacturing. The five fundamental elements listed below are crucial to ensure that the product you create is constructed in a way that is balanced. The equilibrium between resolution, size as well as thickness, orientation and material selection will help ensure the function and aesthetics of your creation.
Size
When you are creating an item one aspect to consider is its size. Every technology has its own ideal format, some are larger than others. Click over here now to get a useful reference on commercial 3d printer.
The FDM machine is able to reach the biggest size of 16 "x 14" 16". It is possible to have your components cut to a larger size before they are fabricated and then put them together with a professional.
The dimensions of your parts will have an impact on the time it takes to build. Larger parts are more difficult to fabricate and will require more materials. This could result in cost increases.
The resolution
The resolution refers to the thickness of every layer that is utilized for additive manufacturing. Depending on the technology employed to create the piece and the process used, a thin layer could reduce imperfections or ridges. High resolution provides better quality surfaces and smoother faces before post-processing. The manufacturing time is longer if the layers are thinner.
If you want an object that has very high resolution, you should choose SLA (Stereolitography) technology that has an average thickness that can reach 25 microns (0.025mm). SLS technology provides very good resolution. i.e. 100 microns (0.1mm). The usual FDM layer thickness is 250 microns (0.25mm) and we provide high-resolution (0.175mm). It is possible to print at smaller resolution (330 microns or 0.330mm). This is a great option for large and less attractive objects that are produced in a short time and with less expense.
Wall thickness
The thickness of your component's walls is an essential aspect of the design that ensures the stability, precision and tolerability in an additive-produced part. The thinner the thickness, the shorter the build time However, too much thickness can lead to a fragile component that has less precise characteristics.
SLS makes it more likely that parts made of thin materials will warp because of the manufacturing process. The components made using the SLS method are susceptible to high temperatures and also the mass of the powder during production. SLS material may shrink when it cools or solidifies. With a thickness between 1mm to 3mm, geometric stability of these properties is much more easily achieved. It is possible to achieve the minimum thickness below 0.4mm. But, this is more risky.
With FDM, for example, the recommended minimum thickness is generally 1.6mm
The orientation
In 3D printing, the orientation refers to how the component is placed on the printing platform. It is possible to place it vertically, horizontally, at an angle , or flat. Making sure that the components are oriented correctly to make them is a crucial element that influences the quality of the finished product, particularly when it comes to the geometric dimensions and tolerance to error. The energy used and the amount of support structures needed are directly affected. All these factors contribute to the overall price of the piece.
Depending on the technology used depending on the technology used, the orientation could differ. In the case of FDM printing, the product has a high elastic force along the X-Y Axis, but is more fragile on the Z direction because of the way the layers are created. This could result in obvious lines in between layers, which may affect the look of your parts. Certain orientations work better for curving shapes. Sometime, orientations that are too high off the surface are not as effective and require additional support.
This being said, we will ensure that you position your parts so that they have the best balance between the quality of their surface and strength of the part, unless specified otherwise.
The material of choice
There are a variety of materials you can select from based on which method you use. The choice you make is usually dependent on the restrictions applicable to your part. It is important that you pick the correct material for your piece. For instance, if it will be subjected to very high temperatures or chemical solvents, you should consider ULTEM (in FDM technology). If it needs to be impervious to impacts, polycarbonate will be a good option.
SLA technology has a wide range of intriguing resins that are suitable for use in a variety of applications. Flexible resin is a product that has similar properties to rubber. If you're planning to create castings with lost wax there is a "castable wax" resin available. ABS (FDM) and nylon (SLS) as well as acrylic resin (SLA) All three can be used for casting.
Style balance
The size, resolution as well as the thickness, orientation and choice of material are the most important aspects of a creation dedicated to 3D printing.When these factors are all considered and balanced, you're certain to have a practical piece that is able to meet your requirements.
