The Best 3D Scanners Under $1,000

3D Scanner Buyer's Guide

Ciclop

Image of 3D Scanner Buyer's Guide: Ciclop

Launched, and until recently maintained, by BQ, the Ciclop DIY 3D scanner kit is a fully open source 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 this 3D scanner can be purchased as a kit; they consist mainly of a customized Arduino board and a Logitech webcam.

The processing of data captured by this laser 3D scanner is a dedicated scanning suite called Horus, also Open Source.

Be prepared: It’s not easy to assemble. BQ once admitted to the difficulty of setup and calibration as well as inconsistencies in the build quality (accuracy) of the individual components for this 3D scanner. You can still find the printable files over on GitHub, however, the official Bill of Materials and assembly instructions are no longer available on the Diwo BQ website — so building your own may take some research.

In terms of being open source and usability, the Ciclop 3D scanner is one of the best, but making it work can be a real challenge – but that’s probably half the fun of such a project. A good learning experience.

Since the Ciclop is open source, several other companies sell kits meaning the Ciclop lives on, albeit under a number of different names. The quality of these kits may vary, so it’s worth researching a given kit and company before buying.

The Occipital Structure Sensor Mark II is a smaller and much more powerful version of its predecessor. (Source: Occipital)

The Occipital Structure Sensor (Mark II) is a freshly-released multi-purpose handheld 3D scanner with a wide range of applications. Unlike its predecessor, the Mark II is mountable and compatible with new iPads and is smaller and much more powerful. It weighs 65g to the old version’s 95g, has a built-in tracking camera with  160° ultra-wide-vision monochrome, boasts higher depth resolution and can even be used both indoors and outdoors.

The Mark II sells for $399, but if you live in the US and have an old Structure Sensor, they’ll swap it for the new one and take $100 off the price. Occipital also offers a bundle for an additional $100 that includes a wide-vision lens, professional 3D scanning software Skanect Pro and free shipping within the US.

The software provided by the manufacturer is called Structure SDK, it offers high-level developers tools and full low-level access for a game and mixed reality development and 3D mapping. Apart from that, the device can be used to create high-quality 3D models of objects for a variety of purposes, including 3D printing.

3D Systems Sense 3D scanner (Image: 3D Systems)

Currently on Version 2 (with no sign of any continued support), the Sense 3D scanner is the successor to the 3D System’s now defunct tablet/smartphone-mounted iSense. Connected to a Windows device (Windows 8 or later) via USB 3.0, the Sense provides a competent handheld scanning solution for capturing models for archival and asset creation for digital content.

Accomplished object tracking makes the Sense’s active building of a 3D model a cinch, giving a handheld scanning solution that outputs relatively high-geometry and good texture quality, quickly.

The Sense 3D scanner has an operating range of 20cm to 160cm, capturing full-color images and seeing all within a 45 degree field of view. That offers pretty good flexibility for a handheld 3D scanner of its size.

Many users caution that achieving good results can be a chore, so temper your expectations going into the Sense. At this price range, there aren’t really any perfect handheld scanners.

HP Z 3D Camera

Image of 3D Scanner Buyer's Guide: HP Z 3D Camera

First debuted at CES 2018, the tech giant HP Inc. made some serious waves with the launch of the innovative HP Z 3D Camera attachment. Focused on offering a much more affordable alternative to the Sprout Pro 3D camera, which costs upwards of around $3,000, the Z is a portable option that can be attached to most monitors.

Best of all, the price of this 3D camera device is just $599. It shares many of the same features as the Sprout Pro, capable of capturing and digitizing 3D objects, 2D documents, and live video. However, it does lack other useful attributes such as projection capabilities and multitouch.

The HP Z Camera uses a technology called SLAM (Simultaneous Localization and Mapping) to track, scan, and construct a 3D model in real time, resulting in high-resolution “computer-graphics-friendly” images and textures can then be used for various 3D and VR applications. Utilizing a 3D depth-sensing camera and a 14.6MP 2D camera, users can scan an object by simply rotating it in your hands and positioning it underneath the camera.

Captured 3D objects can be exported directly to PowerPoint 3D, Paint 3D, and Mixed Reality Viewer. According to the manufacturer, this affordable 3D scanning attachment was made with CG artists, designers, game developers, and artists in mind.

Peel 3D Peel 1

Image of 3D Scanner Buyer's Guide: Peel 3D Peel 1

Striking a balance between professional capabilities and affordability is the distinctly designed Peel 1 3D scanner. Despite boasting a low price tag of $5,900, this Peel 3D scanner still offers some fascinating features that are absent from other devices in the same price range, such as the ability to accurately scan flat or shiny surfaces.

This banana-like system utilizes stick-on targets to adequately capture flat and smooth surfaces. For typical 3D scanning applications, the process is as easy as pointing the scanner at an object and shooting – little to no preparation required.

Using an LED system to generate the structured light, the peel 3D scanner is also safer to use than other laser-based systems. When employing the stick-on guides, the peel 3d is able to reach a scanning accuracy of 0.25 mm and volumetric accuracy of 0.5 mm. Although the base resolution is a mere 0.5 mm, which is lackluster compared to other models, it’s a sacrifice that must be made for the sake of cost-effectiveness.

Shining 3D EinScan Pro 2X

Image of 3D Scanner Buyer's Guide: Shining 3D EinScan Pro 2X

The Shining 3D Pro 2X is the latest handheld 3D scanning system from Shining 3D. Like the EinScan Pro before it, this new and improved model is a lightweight and compact 3D scanner made for professional use, capable of capturing small-to-medium sized objects, and it does so at incredibly high speed without sacrificing quality.

The EinScan Pro 2X offers four different 3D scanning modes: Handheld Rapid Scan Mode, Handheld HD Scan, and Fixed Scan Mode (both with or without a turntable).

With Handheld Rapid Scan Mode, the EinScan Pro 2X is capable of processing up to 1,500,000 points per second (30 fps). While Handheld HD Scan Mode is a bit slower, it does offer an impeccable scanning accuracy of up to 0.05 mm. For both of these handheld modes, the volumetric accuracy can be improved by utilizing markers on the objects you plan to scan. When using Handheld Rapid Scan and Handheld HD Scan modes, the minimum point distance is up to 0.2mm, leading to the generation of high-resolution 3D data.

A higher spec Pro 2X is available in the Einscan Pro 2X Plus, which boasts a faster scan speed, higher single scan range, point distance, and working distance. The accuracy is said to be the same, but there’s a degree more versatility on offer (at a premium — it costs some $2,000 more than the 2X).

Alternatively,  it’s still possible to pick up the original EinScan Pro. Our previous Top Pick before the Pro 2X version usurped it, the original Pro captures fewer data points, slower, but costs considerably less than the new models.

The Artec Eva is considered by many to be the best in class handheld 3D scanner. It is used in just about any field of work imaginable from the aerospace industry to orthopedics and vfx.

The Artec Eva is particularly suited to medium-sized objects (including busts), capturing accurate full-color scans quickly and reliably.

It’s possible to set up more than one Artec EVA 3D scanner to speed up the scanning process — an expensive proposition, but a welcome one to note the versatility of the device.

Utilizing structured light for its scanning method, this makes it particularly safe for scanning people and animals. The EVA requires no calibration or warm-up time and is compatible with tablets, so the whole system is truly portable without the need for an external power plug. The in-house editing software is not free, however, and does not ship with the handheld 3D scanner. Since the data from the 3D scanner can be exported, any third party 3D editing software should be able to get the job done.

3D Scanner Technologies

Before you decide to purchase a 3D scanner for yourself, it’s important that you know what this technology actually is and how it works. First, a 3D scanner captures an object or person. This image data is then transferred into a 3D modeling program, and from there can be altered or modified in the software, printed, inserted into a video game, and so on.

After an object is scanned, the model can be edited or resized via 3D design software. After the model is prepared, it can export into an STL file and be 3D printed. Essentially, this means that anything you see in your daily life can be made 3D printable, whether it be a small object like jewelry or a large object like an automobile.

There are many different technologies and aspects to consider when shopping for a 3D scanner. Keep reading below if you’re looking for more information on 3D scanning technology!

3D Scanner Buyer's Guide

Photogrammetry

Image of 3D Scanner Buyer's Guide: Photogrammetry

This 3D scanner technology predates the age of computers: After the invention of photography, scientists quickly realized they could apply the principle of natural stereo vision to their fields. 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.

3D Scanner Buyer's Guide

Structured Light

Image of 3D Scanner Buyer's Guide: Structured Light

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.

3D Scanner Buyer's Guide

TOF (Time of Flight)

Image of 3D Scanner Buyer's Guide: TOF (Time of Flight)

Time of Flight (TOF) 3D scanners are even more sciencey. 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.

3D Scanner Buyer's Guide

Triangulation (Laser 3D Scanner)

Image of 3D Scanner Buyer's Guide: Triangulation (Laser 3D Scanner)

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.

Which Type of 3D Scanner is the Best for Me?

Selecting the right 3D scanner is no simple matter. There are many criteria to keep in mind before purchasing a device. For instance, a certain 3D scanner may be the best for architectural purposes, but may still prove unsuitable for prototyping. You may benefit from an affordable stationery scanner, or need the versatility of a handheld device.

Before we dig into the different 3D scanners available on the market, let’s take a look at the different aspects that you should consider. We have compiled a list of the most important characteristics to consider when shopping for a 3D scanner.

3D Scanner Buyer's Guide

Field of Application

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.

Type of Object

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.

Dimensions/Distance of the Object

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.

Surface of the Object

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.

Resolution

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?
