Artec Space Spider 3D Scanner Review 06:55
The Artec Space Spider is a handheld 3D scanner. The cameras on the front look like spider eyes— hence the name “Spider”. The 3D scanner is very light and works with blue-structured light. It was developed primarily for 3D scanning smaller objects of between 5 and 30 cm. The manufacturer states the accuracy of the 3D scanner to be within 0.1mm-0.05 mm. Currently, the Artec Space Spider lists for about 20,000 Euro (23,626 USD).

A Closer Look at the Artec Space Spider

On the front right of the Artec Space Spider is the projector. It projects a blue-structured light
pattern onto the object to be scanned. The surface of the object curves this projected pattern .
Three cameras capture the curvature and distortion of the pattern and calculate the geometry of the
object. The color camera is installed in the center. Therefore, the light-emitting diodes are arranged
in a circle. During the scanning process, the camera records the color texture.

The 3D scanner must be connected to a power supply and a laptop during the scanning process. This
is done with two cables: one for power and one for the data transfer. There is also a rechargeable
battery, which makes the power cable redundant. The battery lasts for about three scans.

On the backside of the Artec Space Spider is a button—push forward for 3D scanning and backward
to stop the scan. The Space Spider has the weight and feel of a clothes iron. During the scanning
process, the Space Spider must be connected to a PC or laptop. It works with the software “Artec
Studio”. During the scanning process, you can see real-time capturing on the screen—so if there are
any errors, you can quickly correct and re-capture erroneous areas.

Possible Source Errors During 3D Scanning

When 3D scanning with the Artec Space Spider, 20 cm from the object is ideal. The software “Artec
Studio” displays the optimal distance on the connected laptop. The Space Spider has a measuring
field of view of about 10 cm. This means that for larger objects, the software combines several
partial scans in real-time. The 3D scanner does this by orientating itself on the previously scanned
section while you move around the object. With objects larger than 30 cm, this can lead to errors
because the software has problems combining images correctly.

Negative example: We wanted to record a motorcycle tank with the Artec Space Spider for a
customer. The tank totaled 60 cm in length. While we moved around the tank to 3D scan it, the
errors added up, resulting in an inaccurate 3D scan.

The Advantages of the Artec Space Spider

One big advantage of the Space Spider is its light weight and mobility. It is stored in a transport box
and is ready for use at the customer’s site in 2 minutes—after warming up. Unlike other 3D
scanners, it does not have to be recalibrated after each use, but for an accurate 3D scan, it is
recommended.

Additionally, the 3D scanner has different software settings with which the density of the point cloud
generated during 3D scanning can be modified. The denser the point cloud, the more accurate the
3D scan.

Besides the 3D model, the Artec Space Spider also creates color texture—either as a 4k or 8k
textured map. However, the color quality is not as good as a fine photogrammetric 3D Scan.

The Accuracy of the Artec Space Spider

To test the accuracy, we 3D scanned a ring gauge for a micrometer. This ring gauge has a calibrated
inner diameter of 90 mm. We then compared the 3D scan with a CAD model of the ring gauge. This
deviation analysis (nominal actual comparison) resulted in the Artec Space Spider 3D scanner
providing accuracy within about +-0.05mm.

Conclusion

The Artec Space Spider has a good price/performance ratio. It is mobile and light and is a good entrylevel scanner for professionals. We use it to 3D scan for customers with smaller budgets who need
to balance cost and accuracy.

Swann has been enthusiastic about everything 3D for many years. His roots lie in analog holography, which brought him to digital 3D-modeling in 2011.

The rapid progress of various 3D-scanning techniques fascinated himso much thathe founded Holocreators together with his brother Miro Rack in 2015.

With the help of specialized 3D scanners, you can 3D-scan people and animals. This allows you to create 3D models that can be 3D-printed or used for 3D animation. We'll show you three different devices that make such 3D scans possible.

Kitbashing is associated with model making. It is composed of the words "Kit" and "Bashing". “Kit” refers to "model kit". So, when a model maker is "kitbashing", he blends parts from different model kits. Similar to a collage. The model maker combines several individual models into an entirely new model.

A NURBS model consists of points connected by curves. A polygon mesh consists of thousands or millions of small triangles. CAD surface models are usually created using NURBS surfaces, while 3D scans are typically exported as a polygon mesh. The conversion from a polygon mesh to a NURBS model is called "reverse engineering".

Reverse engineering enables us to create a copy of an object. For this purpose, the part is 3Dscanned, then the 3D scan data is converted into a CAD format, and finally, the part is manufactured. All these steps result in noticeable deviations. If an error adds up over multiple steps, then we call this error propagation.
