ATLAS 3D is a 3D printable laser scanner kit based on the Raspberry Pi platform that should come as an affordable good quality DIY solution that you can build yourself and get the ability to 3D scan yourself with good quality and at affordable price. The project was published on Kickstarter looking to make it from a prototype to a widely available product with the help of crowdfunding. The goal of the project was just $3000 USD and it has been passed in no time due to the big interests from users that apparently want to have the ability to get an affordable 3D scanner that is able to provide them with good vitality and speed – something that is apparently still lacking in the world of 3D scanners.

ATLAS 3D works by illuminating an object with laser light and then using 3D triangulation to generate a point cloud for each location where the laser hits the model. Neighboring points are then connected as triangles to form a 3D model. This model can be used as-is for many purposes or it can be processed in a software package such as Meshlab to make it water-tight and print ready. All of the software runs onboard the Raspberry Pi, so there are no required drivers or software packages to install. A web browser is used to communicate with the scanner on your home network. Once a scan is performed, the web browser is used to download the resulting models.


The ATLAS 3D scanner should be able to provide better quality than a MakerBot Digitizer at the quarter of the price, though it may still be as good as more than 10 times expensive a NextEngine for example (at least in terms of resolution). This is at least based on the comparison that the author of the ALTAS 3D project has put up on the Kickstarter page. The ATLAS 3D scanner will be available for $209 USD with everything you need apart from the parts you will need to 3D print, so a 3D printer is required for you to get the full product and you will of course need to assemble everything yourself. You might be able to get the 3D scanner a bit earlier if you manage to get among for the early bird supporters on Kickstarter and get your kit as early as April. More units should be available in May and June. Furthermore since this is a free as in open source, open hardware, and open electronic design 3D printable turn table laser scanning platform you will be able to get everything you need from other sources as well and completely build the product yourself.

3D scanners are not that new as a technology, however with the increased interest in 3D printing in the last few years the interest in 3D scanners has also increased significantly, and that goes especially when talking about affordable 3D printers and 3D scanners. A 3D scanner should in theory allow you to scan a real world object into a 3D model that later on you will be able to print into a physical object again with the help of a 3D printer. This could be especially useful for people that are interested in 3D printing, however are not very keen on learning 3D modeling. You should however be very aware of the fact that 3D scanning, much like 3D printing, may be a bit overhyped and is not as easy as it may be represented by companies willing to sell you their products for 3D scanning. This is especially true when we are talking about more affordable 3D scanner solutions that are at a sub $1000 USD level, but can also be very true for models that going higher in terms of price at like $2000-$3000 USD that can still be considered as cheaper consumer oriented products. Nevertheless the concept of 3D scanning is something that we are also interested in with both its advantages and disadvantages at the consumer level of products as there are significantly better and more expensive professional models available, similar to such 3D printers, but our focus is on the more affordable solutions targeted at the normal users.


The first thing about 3D scanners that is often not getting enough attention is the quality you can expect to get when you scan a real world object. You should be prepared not to expect a great level of detail of the 3D model that you will get as a result from a 3D scan, while the general shape and some of the detail will mostly be preserved, the finer details will most likely be lost. Also be prepared to spend some more time initially getting to know what the best conditions for scanning are and how to properly use your 3D scanner for best results. 3D scanning usually takes some time and this can greatly vary from one 3D scanner to another, and then you may also need some additional time to work on the scanned 3D model as well. The software that stiches all of the data that gets acquired during the scanning process that should create a solid three-dimensional model is not perfect and very often you may need to fine tune the model for the best results. Do note that most consumer oriented 3D scanners also do allow very limited size of the scanned objects and if they offer more freedom and larger scale scanning often the results are not as good as with smaller objects. Still 3D scanners are a fun thing to play and experiment with, just do not get unrealistic expectations on what the resulting 3D scanned models will look like. You should also be prepared that when you 3D print a 3D scanned object in a single color the final result may be even less detailed than what the 3D model you got.

On the images above you can see the MakerBot Digitizer along with an original Gnome figure that was created in a 3D modeling software and then printed in 3D and painted to make it look really nice. Then the figure has been scanned with the MakerBot Digitizer and printed again on a 3D printer from the scanned 3D resulting model. While the end result still looks quite good, you can clearly see that most of the finer details are gone and there are some differences in the larger details that no longer seem as distinguishable as on the original 3D print of the Gnome. Of course adding color might help in making the two Gnomes seem lore alike, however this is a good example that should bring your expectations from 3D scanners to a more reasonable level.
