3dp_3dscan_buying_guide_banner3D scanning is a rather broad term that includes several different types of technologies and processes, but in general it is the process of capturing real world data and converting that data into a 3D model. It has been used for years in industrial and commercial applications ranging from surveying construction sites and taking accurate measurements of a room to preserving a digital snapshot of a crime scene and cataloging artwork and fossils. However, as 3D printing became more common, especially for makers and enthusiasts, the desire to capture real objects and transform them into 3D printable objects has grown.

The market has, naturally, responded and there are now more low- or lower-cost 3D scanner options available than ever. With prices ranging from a few hundred to a few thousand dollars, there are 3D scanner options available for just about every budget. When deciding which is the right 3D scanner to purchase depends entirely on what exactly it will be used for, and how much detail you need it to be able to capture. (You can also check out our 2016 3D Printer Buying Guide for more details on that side of the technology!)


SOFTWARE OPTIONS

Depending on what you are looking to scan, it turns out that you may not even need to buy a 3D scanner. It is entirely possible that you already have the only tool that you will need to create a three-dimensional model right in your pocket. There are a few software options that can take still images, even from your smartphone, and extrapolate the data to create a fully three-dimensional model.

This process is called 3D photogrammetry, and it starts by taking several images of the same object from different angles. The more images that are used, the sharper the details on the final 3D model will be. The process can work with as few as three images, or for extremely detailed models, dozens of images can be used. Not only is this a less expensive option, but it is perfect for capturing a 3D object in public or out on the go when you may not want to carry extra 3D scanning equipment with you.


Autodesk 123D Catch

3dp_3dscan_autodesk123d_catchPrice: Free (Or $9.99 month for 123D Premium)
Technology: 3D Photogrammetry

Because 123D Catch is part of the Autodesk cloud-based 123D ecosystem, Catch is perfect for loading onto a smartphone or tablet. That makes this the ideal option for capturing objects in public that can’t be 3D scanned in the studio, like artwork in museums, large structures and objects found in nature.

Resolution: N/A
Pros: No 3D scanner needed, objects of all size can be captured, free software for most features, easy to use
Cons: Limited functions, quality dependent on lighting and number of images, can take several minutes to capture target object, not good for capturing people or animals


Agisoft PhotoScan

3dp_3dscan_agisoft_photoscanPrice: $179
Technology: 3D Photogrammetry

Agisoft PhotoScan is a standalone software package that has specifically been created to generate high-quality 3D models using 2D photographs. It is primarily aimed at museums or libraries for the purpose of archiving their collections of artifacts and artwork, and is capable of producing extremely detailed 3D models.

Resolution: N/A
Pros: Capable of high-quality 3D models, one time license fee, easy to use, lots of options

If spending several hundred dollars on a 3D scanner is simply out of your price range then there are a few lower-cost DIY options available.


Xbox Kinect with ReconstructMe

3dp_3dscan_kinect_reconstructMePrice: Kinect (varies) ReconstructME (Free)
Technology: RGB camera, depth sensor

This is about as DIY as it gets when it comes to building a low-cost 3D scanner. Thankfully Microsoft has released a peripheral that is really an extremely high-powered depth sensor and RGB camera, and left it open enough to be used for other applications. In this case, pairing an Xbox Kinect (You can easily find them on eBay) with free software like ReconstructMe is all you’ll need to 3D scan people or objects.

Resolution: Varies
Pros: Inexpensive, versatile, free software
Cons: Windows only, limited resolution, uneven quality


BQ Ciclop

3dp_3dscan_bq_cyclopPrice: $280
Technology: Laser triangulation

The Ciclop is an open source desktop 3D laser scanner that uses 3D printable components so it can be manufactured quickly and cheaply. There are also kits available, both assembled and unassembled, and parts list and free STL files can also be found online. Because a laser 3D scanner is a very delicate piece of hardware, assembling a kit yourself can be difficult, so results may vary depending on your level of expertise.

Resolution: 0.5mm
Pros: Open source, can be purchased as a kit, easily modified and improved
Cons: Quality depends on the user, no customer service or tech support, 3D printed parts may not be as strong as traditionally manufactured parts


LOW-COST HANDHELD

A handheld 3D scanner will allow a much greater range of 3D capture than a turntable 3D scanner. These types of 3D scanners are typically used for capturing people and large objects, and even these low-cost models can capture a surprising amount of detail. Typically capturing an object the size of a person will take three to five minutes, however the more information that you capture, the higher the quality of the final 3D scan. These low-cost options are probably not ideal for high-end commercial use, but they can offer small businesses and individuals the ability to quickly capture 3D data, including colors, patterns and even texture.
