3D Scanning an Engine Compartment in Minutes- not Hours




Have you ever had a part in your hand you needed to get into CAD? Push the calipers and micrometers aside, instead grab your Artec 3D Scanner. This is the new way to go from a physical part directly into digital format and into CAD. Yes, technology this great looks expensive, but the Eva Lite checks in at only $9,800 compared to similar technology that sells for north of $50k. Artec 3D has become a global leader for 3D Scanning solutions for inspection, engineering, and marketing, CGI special effects, and much more.

Artec 3D has 2 different flavors of the Eva product, the Eva, and the Eva Lite. The only difference between the 2 is that the Eva Lite does not use, or capture color. This can impact the ease of use for the Eva product, but there are some simple tricks for the Eva Lite when scanning objects that have very little geometry. Also, the good news is an Eva Lite can be updated to an Eva later on.

These examples below describe the difference between Eva and Eva Lite, (and the second half of the video is also scanning in “Eva Lite-mode”.)

  • Imagine 3D scanning a wall that is painted white- there is no way a scanner knows it is indexing along the part, no geometry… no color.
  • With the Artec Eva, a user could write something on the wall with dark chalk and the Eva would be able to index by using the color to track, Eva Lite would not.
  • We the Eva Lite, a user could make a small ball from masking tape to create a geometry to stick to the wall. As long as the masking tape balls are placed with 3-4 of them in the field of view (536 x 371mm) at all times while moving along the wall. Both Eva, and Eva Lite could scan the flat wall
  • Also note, the geometric masking tape balls will easily be removed with the post-processing tools in Artec Studio software after the scan is processed and converted to a mesh.

The Artec Eva and Eva Lite scans at a speed of 16 frames per second. This is another reason why the scanner can move so swift and smoothly without losing tracking. Users take it for granted who use the Eva regularly, but when compared to an Artec Space Spider, Artec 3D’s highest precision device today, the gain in speed before loss of tracking occurs is quite notworthy. Conversely, when compared to the published specs for Artec’s upcoming Leo device, which scans at a speed of 80 frames per second, many are drooling in anticipation to see just how smooth scanning will be with the Leo.

16 frames per second is great, but a scanner needs to be accurate to be used in the real world. The Artec Eva can hold a 0.100 mm (or 0.004 in) accuracy on scanning even larger parts. There is a 0.03% margin added to that for each meter over one meter, but for a scanner this fast, to have a published accuracy of 0.1 mm is VERY good, and good resolution for feature detail. Make no mistake though the Artec Eva is not for ultra-fine featured geometry like splines, or very intricate components. As a rule of thumb, if your part has features that go below 0.500 mm on a regular basis, you should probably consider a different scanner, or the best solution is to combine this with the Artec Space Spider by patching in high resolution Spider scans into the scans from the Eva where high-detail is needed. If you are scanning large, or organic shapes, you really have no need for that high resolution, and the Eva will be the best solution out there in terms of value.

When it comes to value, the Eva is tough to beat. In fact, has awarded the Eva with the title of “Best Scanner Under $50k“. While there are a number of inexpensive 3D Scanners coming into the market, for the industrial user, where time is money… you will not find the repeat-ability, or predictability of the Artec Eva for less money.
