Printing In 3d 5 Important Aspects To Take Into Account

When thinking about additive manufacturing there are several important elements to consider regarding the design of the 3d printing infill. These five essential elements are crucial to ensure that your item is created in a balanced way. Your work will be practical and attractive if it's properly balanced in dimensions the resolution, thicknesses, orientation, and material choice.

Size

Another aspect to take into consideration when creating your item is it's scale. Each technology has an optimal format, and some are larger than others, while some are smaller. The FDM machine is capable of reaching the largest size that is 16 "x 14'' x 16". It is possible to have your components cut to a larger dimension prior to fabrication and then put them together with a professional. Fabrication time will be affected by the size of your parts. Large parts take more time to construct and will require more material, resulting in higher costs.

The resolution

The resolution is the thickness of every layer utilized in additive manufacturing. Based on the method used the thinner layer will lessen the appearance of ridges or imperfections that might appear on the surface of a piece. High resolution 3d printer calibration can provide an even surface and superior quality prior to any 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 with an average thickness that can reach 25 microns (0.025mm). SLS technology provides very high resolution. 100 microns (0.1mm). FDM layers are typically 250 microns in thickness (0.25mm). We also provide high-resolution (0.175mm). Printing can be done at smaller resolution (330 microns or 0.330mm). This happens to be a good option for larger and less appealing objects that can be manufactured quickly and at a lower cost.

Wall thickness

The fundamental characteristic of your design is the wall thickness. This will ensure stability as well as precision and tolerability for parts made by additive manufacturing. A thicker wall reduces construction time. But, too thin parts may not have as specific characteristics and could be more fragile.

Thin parts built with SLS are more susceptible to warping due to the the manufacturing process. SLS pieces are exposed to extreme temperatures and also the weight of the powder during production. SLS material can shrink when it cools down or solidifies. These properties are more durable when the thickness is 1mm and 3mm. It is possible to achieve a minimum thickness below 0.4mm. This is however riskier. Visit our website to find out more about stl to obj.

FDM is one example of a material with a minimum thickness that is 1.6mm

The orientation

The orientation of a component in 3D printing refers to its location on the printer platform. You can place it horizontally, vertically, at an angle or flat. Orienting the components correctly for fabrication is a critical step that affects the final quality, especially when it comes to the geometric dimension and tolerance to errors. The energy used and the extent of support structures needed are directly affected. All these elements contribute to the overall cost of the part.

Depending on the type of technology employed, orientation may vary. When using FDM the part that is printed is extremely elastic force on the X-Y direction, however it is weaker on the Z direction due to the method in which the layers are created. This can lead to visible lines between layers which may affect the look of your components. This is why certain orientations are recommended for curves. Sometime, orientations that are too high off the surface will not be as effective and will require more support.

That being said, we will make sure to position your parts so that they have the highest ratio of the quality of the surface and the strength of the part, unless specified otherwise.

Material selection

There are many materials that you can pick from, based on the method you decide to use for printing your 3D model. The requirements of your part will determine the material you choose. It is essential to pick the correct material for your piece. If your part will be subject to extreme temperatures or chemical solvents, you should consider ULTEM (in FDM tech). Polycarbonate is a good option for those who require a resistance to impacts.

SLA technology also provides interesting resins for various applications. If you're looking for a substance that is similar to rubber, try using a the flexible resin. Castable wax resin can be found for those who want to make a lost wax casting. On the other hand, if you just would like to have the item in hand without a particular purpose, ABS (FDM), Nylon (SLS) and acrylic resin (SLA) can do the job very well for a reasonable price.

Design balance

You can create a 3D printed part which is useful by analyzing the size as well as the resolution, thickness, and the orientation.
