High resolution

Definition

High resolution refers to the ability of a digital imaging system to capture and reproduce fine detail in images, typically measured in dots per inch (DPI) or pixels per inch (PPI). In the context of additive manufacturing, high resolution is crucial for producing intricate designs and precise geometries, allowing for better surface finishes and enhanced functionality in printed parts. It directly impacts the quality and accuracy of 3D-printed objects, making it a vital aspect in technologies like Digital Light Processing.

5 Must Know Facts For Your Next Test

1. High resolution in additive manufacturing allows for the production of complex geometries that traditional manufacturing methods may not achieve.
2. In Digital Light Processing, high resolution is achieved by using a digital micromirror device (DMD) that controls the light exposure with precision, enhancing detail.
3. A higher DPI value generally indicates better image quality, which translates into smoother surfaces and finer details in printed parts.
4. Increased resolution can lead to longer print times due to more layers being needed to achieve finer details, impacting productivity.
5. Achieving high resolution often requires advanced materials and printer calibration, which can increase costs but results in superior quality outputs.

Review Questions
