Technology, as they say, is here to make life easy. 3D technology especially the scanners thus remains a popular technology for easing work technicalities among many professionals. These include the celebrities who may want to incorporate special effects in their movies, architects who want to design or modify construction designs and engineers who want to improve on every design idea they actualize. With 3d technology, these professionals can capture the objects shapes in the form of a 3D file into the computers, allowing for further editing and printing. Thus, to land on the best 3D scan for the best services in your area of specialization, the following guide will offer a step by step advice on what to do and consider as a smart buyer.

Types Of 3D Scanners And How To Buy

3D scanners employ two methods in their scan operation. Namely: contact and non-contact, hence the contact and non-contact scanners. Contact scanners require direct contact with the object during the scan process while the non-contact utilizes either the laser or radiation to collect information on the object in question. 3d scanners are usable with 3D printing. Also, to run their system, the scanners combine the CAD software and the principle of data collection about an environment, object or a person. With a single scan, therefore, you can obtain lots of object information via the reverse engineering process.

Depending on portability and size, scanners exist in three major types namely:

Desktop 3D scanners: these scanners are suitable for scanning small and medium-sized objects. They feature a footprint that allows for fitting on a desktop.

Handheld 3D scanners: these scanners are lightweight hence portable. Their versatility makes them an ideal option for both object and body scans. Due to their small size, they necessitate the use of hands in operation. Also, most handheld 3D scanners are not wireless and require connection to a computer hence restricted mobility.

Industrial 3D scanners: these scanners, unlike the above two are high quality and usable by professionals. They, therefore, feature high precisions, shape and designs for quality output.

In order to classify 3D scanners, an understanding of the technology they employ is important. The technology thus further classifies these scanners as follows:

Laser triangulation: 3D scans under this technology utilize the single laser or laser line to scan objects. The scanner casts the laser. The laser’s light then reflects on the object and its trajectory undergoes modification after which a sensor picks it. This modification combined with the trigonometric triangulation enables the system to decide on the deviation angle. This angle relates to the scanner object distance. Hence, where the scanner captures adequate distances, it maps the surface’s object more easily to generate a scan.

Laser triangulation based scanners feature high accuracy and resolution. Despite this, they experience problems when scanning shiny and transparent surfaces due to their high sensibilities.

Structured light: scanners that embrace this technology employ the trigonometric triangulation technology alone unlike those that use laser triangulation. In this case, the technology relies on some linear pattern sequence that falls on the object in question. The software system then examines each line’s ends and computes the scanner object distance. The structured light is either blue or white and is common in the DLP technology projectors. In most instances, the pattern projected comes in the form of light rays series or random dots in some instances.

When it comes to speed and resolution, the structures light technology takes the lead. This technology is also unique in that it can also scan human beings. Despite these benefits, scans that use this technology are too sensitive to light hence some technicalities when used outside.

Photogrammetry: Photogrammetry as a science entails the use of computerized images and geometrical algorithms to measure photographs and enhance recovery of exact surface point positions. The technology first analyzes photographs from respective photography points and auto detects pixels that correspond to the exact physical location. For this to happen successfully, you need a very powerful computer which you will feed with the camera’s lens distortion and focal length data. The challenge, however, may come where you are dealing with a large number of photographs and want to retain a high accuracy level for each.

Photogrammetry, despite its complication, features high speed and precision. Moreover, through scanning with this technology, you will be able to use different scales to reconstruct your subjects from whichever capture viewpoint. On the other side, however, this technology has a high sensitivity to the input photograph resolutions and uses more time to scan the photos due to the complex algorithms it has to run.

3D scanning on a contact basis: As its name suggests, scans that use this technology utilize physical contact of the object where a probe moves on the object and is able to record information about the object through contact. This element may also attach to a specific point on the object to collect all the information. Some specific 3D scanners that embrace this technology include the Coordinated Measuring Machine, useful in inspecting parts both manually and automatically through software and computers.

Contact based scanners have high precision and are very efficient in shiny and transparent surfaces. However, they perform at low speed and are inefficient with the organic varying shapes.

The laser pulse (Lidar): this technology inclines to the flight of a laser beam. The laser beam undergoes projection where it collects on a sensor. Thus, the time the laser takes to travel gives the geometrical information on the surface in question. This time comprises of the lidar and the shifting phase lasers which are a sub-class of the Lidar 3D scanners.

Laser pulse based scanners are ideal for scanning huge objects and environments. Their disadvantage, however, is their slow pace that requires maximum patience on the user’s end.
