The 3D Systems iSense 3D scanner is designed as a low-cost extension for your iOS device. Unfortunately, it isn’t compatible with other systems like Android, Windows or Linux. Depending on the Apple device you have, the iSense 3D scanner comes with the appropriate ‘case’ to fit your device but is otherwise identical in regards to the technical specifications.

The iSense is quite capable and impressive. It was considered to be one of the best 3D scanners when it came out first. The handheld 3D scanner has one of the largest ranges in scan volume in its class. Anywhere from the size of a shoe to the size of an SUV.

The mobile app includes features that automatically detect which object the user wants to 3D scan and ignores everything else. The software offers an easy file editor that optimizes models for 3D printing. It is incredibly easy to upload your captured 3D models a Cube 3D printer at home either directly or remotely through cloud printing. This feature makes iSense the best 3D scanner. However, the handheld 3D scanner does save the model in STL, PLY or OBJ file types. This means any 3D printer compatible with one of those file types should be able to 3D print your captured 3D scans all the same.

The FabScan is a DIY 3D scanner kit that Francis Engelmann developed as his bachelor’s thesis in 2011. In its basic form, it was a laser 3D scanner synchronized with a turntable. The design was improved by subsequent students at RWTH Aachen to push the price from $150 to only $100. However, a kit with all the required parts can set you back up to $200.

Before making a choice, it might also be worth comparing the different versions of the FabScan. The most recent incarnation makes use of the Raspberry Pi Cam in order to improve the scan quality. While building a laser 3D scanner at home is certainly not everyone’s cup of tea, the FabScan is the best 3D scanner for anyone who wants to learn all about 3D scanning from scratch.

The BQ Ciclop DIY 3D scanner kit is a fully open sourced project licensed under the GPL license. Following the RepRap philosophy, the many components of the Ciclop are 3D printed. The electronics at the heart of the machine can be purchased as a kit; they consist mainly of a customized Arduino board and a Logitech webcam. This laser 3D scanner is operated with a dedicated scanning suite called Horus, also Open Source.

The software developed by BQ called ‘Horus’ is a multi-platform application that is the user interface for the 3D scanner. It allows the user to calibrate the lasers, control all the components like the camera, lasers, motor and LDR (Light-Dependent Resistor). And most importantly, it allows the user give the command to 3D scan the object on the turntable. The device needs to be assembled by hand. The frame components are 3D printed, and the 3D scanner is controlled by the ZUM BT-328 board and ZUM SCAN which is both based on Arduino technology.

Be prepared: It’s not easy to assemble. BQ has admitted to the difficulty of setup and calibration as well as inconsistencies in the build quality (accuracy) of the individual components. It is worth noting that the files for the printed components have been released on Thingiverse by BQ for the extreme DIY people out there who would like to source all the parts themselves and print the frame out. In terms of open source and usability one of the best 3D scanners, but making it work can be a real challenge.

Using images taken from two slightly different positions, they were able to measure and determine the location of points objects in 3D space, experts call this process ‘triangulation’.

To this day, Photogrammetry is used by land surveyors to compile maps with high precision; this has proven to be especially useful in mountainous regions that are difficult to access for surveyors or to 3D scan by other technologies.

Modern computer programs triangulate entire buildings or objects as small as shoes. Nowadays even phones can be turned into portable 3D scanners, simply by installing an app. The precision is largely due to the quality of the images. The more pixels you feed to your program, the more data it has to chew on. To generate a complete model many pictures have to be taken while moving around the objects in increments of 15 to 30 degrees; repeat this in different heights, especially when 3D scanning complex objects, i.e. that have many occlusions. Keep in mind that in order to triangulate a point, it needs to be photographed at least twice – otherwise your mesh will have holes. So don’t be shy when you snap your pictures.

These devices project geometric patterns onto the surface of a given object, while a camera registers the distortion of the image. Based on the displacement of the pattern, it is possible to calculate the location of every point. Since the patterns can only be projected from one vantage point at a time, multiple 3D scans have to be combined to form a complete 360° mesh. Some manufacturers circumvent this constraint by mounting the object on a motorized turntable and stitching the 3D scans together automatically. These 3D scanners are very accurate, the resolution ranges in the tens of micrometers. Unlike 3D laser scanners, this technology is completely safe to apply to humans and animals. The 3D scanning range is limited to a few meters. Structured light technology is found both in stationary and in portable 3D scanners.

Time of Flight (TOF) 3D scanners are even more sciency. They determine the distance to an object by measuring the time a sent out a laser or infrared beam takes to be reflected to the 3D scanner. The essential ingredient in this device is the speed of light. The round-trip-time establishes the distance traveled by the light beam. If you consider that it takes sunlight a mere 8 minutes and 17 seconds to reach the Earth, you get an idea of how precise the sensors in these scanners are in order to work. But even the mighty TOF scanners have shortcomings, differences in temperature, humidity, and other factors affect the speed of light and impede the 3D scanner’s ability to accurately measure the round-trip time, so their accuracy is comparatively low, in the range of centimeters. They are mostly used scanning large structures like buildings. Like with other technologies, it is not possible to create solid meshes in one scan. TOF-3D-scanners using laser beams should not be used when 3D scanning people or animals. Many devices using this approach are designed as portable 3D scanners.

Triangulation 3D scanners, aka laser 3D scanners, are similar to photogrammetry and structured-light 3D scanners in that they use the same basic geometric principle to determine the location of a point in space. The laser 3D scanner projects a laser beam on the object and a camera registers the place where the laser hits the object. Since the angles and measurements of laser and camera are known, the laser dot (or line) can be accurately located. These 3D scanners are famously accurate, the resolution ranges in the tens of micrometers. On the flipside, their range is limited to only a few meters. Triangulation 3D scanners emitting a laser line are capable of scanning moving objects. This technology is usually not found in portable 3D scanners.

Contact 3D scanners physically touch the object which is resting on a surface or fixed to some form of rig that holds it in place. Usually, this is a slow process, as even minor vibrations can distort the scan. Though these 3D scanners produce precise scans that used quality control in engineering industry, the probes may modify or even potentially harm the scanned objects; for this reason, contact 3D scanners are not used for heritage preservation.

The first question you should ask yourself is: what do you want to use the scanner for?

The requirements vary depending on the field. For example, a game developer simply creating game assets will be interested in not just a high-resolution mesh but also the texture of the object. If so, photogrammetry will be the logical solution in this case. However, a maker who wants to 3D print something he saw in reality will be more interested in the exact measurements of the object. Therefore, they will probably choose a 3D scanner based on structured light. Your should also decide very early, where you want to 3D scan your objects. If they are relatively small and you can bring them to your office or home, buy a stationary 3D scanner. If not, you need a portable 3D scanner.

You should determine what it is exactly that you want to 3D scan. There is no device that covers all areas of application.

For 3D scanning people and animals, you can’t use a 3D laser scanner since it might cause damage to the eyes. Photogrammetry might be a good choice, but this technology requires the subject to stay perfectly still. So while you might get great 3D scans from your friends and family, you may find your dog a difficult subject.

Laser 3D scanners are a great choice if want to scan large, inanimate objects such as buildings or vehicles.

In case you are interested in reverse engineering, that is to say, you need extremely accurate measurements, structured light or contact 3D scanners will do the trick.

However, Contact 3D scanners are not an option in projects concerned with heritage conservation, since the process may alter or even destroy delicate items. In this case, the best 3D scanner is a structured light scanner.

Most consumer 3D scanners (structured light) are designed for 3D scanning objects the size of your average tea kettle from a close range. But it’s true, that you can often ‘stitch’ multiple 3D scans together into one piece. Generally speaking, the bigger your objects are, or the farther away, the more expensive a 3D laser scanner will be. Exceptions are photogrammetry programs, that are normally reasonably priced and produce excellent results.

Another factor to keep in mind while buying the best 3D scanner is the surface of your object. Both photogrammetry and structured-light 3D scanners have serious problems with reflective and transparent surfaces which cannot be processed and will result in distorted and fragmented meshes. Even the best 3D scanner will not produce satisfying results when faced with ill-suited surfaces. If your heart is set on these technologies, this constraint is often overcome by applying a thin layer of opaque lacquer.

Finally, the single most important feature in many fields of application is the accuracy of the 3D scans. Contact 3D scanners are capable of extreme accuracy, but their prices range from $30.000 to $200.000. Again, you should ask yourself: what do you want to use the scans for? How much resolution is enough to get the job done?
