Why is dimensional accuracy important?

Why is dimensional accuracy important?

Dimensional measurement is of fundamental importance for interchangeability and global trade. It is how we ensure that things will fit together. Without global length standards as the basis for standardized parts globalized industry would not be possible.

What is filament accuracy?

Different filament brands will have different degrees of accuracy. For example, our AIO Robotics filament has accuracy of +/- 0.02mm, meaning that the maximum the filament will differ from the 1.75mm diameter is within 0.02mm.

What does dimensional accuracy mean?

Dimensional accuracy refers to how well a printed object matches the size and specifications of the original file. For accurate parts, choose the printing process and materials that are most appropriate for the design.

What is dimensional accuracy in 3D printing?

The accuracy of three-dimensional (3D) printing is how the dimensions of a measured product are close to its original model’s nominal values. Thus, dimensional accuracy is essential for determining the machine’s reliability to produce each object according to the expected results.

What is the importance of dimensional inspection?

Dimensional Inspection, also called Dimensional Metrology, assesses the geometric characteristics of machined parts and products to verify their compliance with design specifications. Dimensional inspection services ensure the accuracy of the product features that can affect reliability and functionality.

What are the two types of dimensional inspection?

There are three primary types of dimensional inspection equipment: precision hand tools, contact sensor systems, and noncontact sensor systems.

Why is dimensional accuracy important in 3D printing?

The dimensional accuracy of your 3D printed parts can be extremely important if you are creating large assemblies or parts that need to precisely fit together. There are many common factors that can affect this accuracy such as under or over-extrusion, thermal contraction, filament quality, and even the first layer nozzle alignment.

Which is more important dimensional accuracy or dimensional uniformity?

Dimensional accuracy is not as important as dimensional uniformity. I can print with undersized (or oversized) filament, adjusting the flow appropriately, provided the filament has a consistent diameter. When creating filament in-house, without expensive equipment, it is difficult to maintain the same diameter throughout the entire extrusion.

What happens when source filament becomes wider than expected?

If the source filament becomes wider than expected, the output will have overflow, or more material than desired will be deposited, and this will certainly affect the quality of the piece. Put it simply: they say 1.75 mm with a ± error of 0.05 mm. Which means your flow may vary ±2.9 % while you are printing creating blobs and such.

How big should a print head be when making filament?

When creating filament in-house, without expensive equipment, it is difficult to maintain the same diameter throughout the entire extrusion. It is likely this extrusion diameter (when creating filament, rather than the output of the actual print head) to which Barafu is referring when he mentions his tolerances: +/- 0.05 mm in diameter.
