What are handheld 3D scanners?

Handheld 3D scanners are compact systems employed to retrieve the three-dimensional structure of objects through laser or structured light projection and reflection examination. These allow for detailed and high-resolution 3D models, with the immersion breath of the latest scanners, making it an important tool for many industries including manufacturing, healthcare and design. The global 3D scanning market was valued at USD 4.82 billion in 2022 and is projected to grow at a CAGR of 8.5% from 2023 to 2030, according to a 2023 report by Grand View Research, and as more 3D scanning applications emerge, its popularity seems to increase; handheld devices are gradually evolving into the mainstream market because while 3D optical scanners have better performance, handheld devices are more portable and versatile.

Most handheld 3D scanners feature a scanning resolution between 0.1 mm to 0.5 mm for detailed models. Devices such as the Revopoint POP 2 offer accuracy levels of up to 0.1 mm, which is why they are lightweight and have a range of applications including reverse engineering, dental prosthesis and more. Weighing as little as 200 grams, these scanners enable users to fit them around objects of different sizes and shapes.

Most handheld 3D scanners use structured light or laser technology to gather surface details. Structured light scanners cast patterns on the object and study distortions to recover its 3D shape, providing benefits in terms of speed and detail capture. On the other hand, laser-based devices work perfectly when scanning reflective or dark surfaces thanks to their ability to go through difficult material.

A vivid example of this was seen in 2021 when archaeologists used handheld 3D scanners to digitally preserve a 2,000-year-old Roman statue. Their lightweight and portable design facilitated on-site scanning without risking damage to the object. Such examples show how handheld devices can allow work in different contexts, from retaining cultural heritage to making prototypes while walking around.

Handheld 3D scanners vary greatly in price due to their different capabilities — you can find models starting at $500 or go and spend upwards of $20,000 on a professional-grade device. Higher-end scanners come with advanced features like multi-spectral imaging, and faster data processing; however, you could find affordable solutions for hobbyists or small businesses. In a 2022 study conducted by MarketWatch, handheld 3D scanners delivered a 15% cut in prototyping cost and a 25% improvement in project timelines for small businesses.

As Elon Musk said, “The first step is to establish that something is possible; then probability will occur.” It ties closely to the rippling effect of 3d scanner technology, allowing for innovative progress and problem-solving in figures across multiple landscapes. Handheld 3D scanners are revolutionizing fields, providing the ability to scan and reconstruct complicated items with unparalleled ease, merging portability, precision, and adaptability.
