Devices capable of generating three-dimensional digital models of physical objects, and whose components can largely be fabricated using additive manufacturing techniques, are becoming increasingly accessible. These devices leverage principles of structured light, photogrammetry, or laser triangulation, coupled with open-source software and readily available electronics, to achieve functionality. An example involves utilizing a Raspberry Pi, a camera module, and a laser line generator, with a custom-designed, additively manufactured enclosure to create a functional digitizing system.
The increasing affordability and customizability of these systems allows for democratization of 3D scanning technology. This accessibility benefits fields such as education, where students can learn about 3D modeling and digital fabrication, and small businesses, which can use the technology for reverse engineering or product design. Historically, professional-grade three-dimensional digitizing equipment carried a substantial cost, limiting its adoption to specialized industries. The current trend enables broader experimentation and application.
The following discussion will delve into the various methods employed in creating these systems, examine the associated hardware and software considerations, and explore the applications and limitations of designs created through additive manufacturing.
