In today’s video tech tip, I will be adding scan data from the Artec Space Spider to our existing Artec Eva scans to add fine details in those hard-to-reach areas.
With resolution up to 100 microns, 3D scanning enables designers to digitize physical objects and accurately use them in their designs. 3D scanning collects fast point cloud data frame by frame. The process is much faster than slow manual inspection methods. It provides quick exports of meshed data for reverse engineering, inspection, and the capability to create watertight files for 3D printing.
The benefit of using both Artec 3D scanners is that the Eva captures data quickly at 14 frames per second, covering a lot of ground quickly, whereas the Space Spider is a bit slower but captures small details with ease.
Artec Eva 3D Scanner for Quick and Easy Scanning
Let’s begin our Eva scan. We started on the left side of the artwork and working our way down, scanning about 14 frames per second, which is pretty fast. In the middle of the part you’ll notice that there’s an angel’s face. That is where we will go back and pair with our Space Spider to add fine resolution and more detail. Now, let’s plug in our Artec Space Spider to add a new fine detailed 3D scan to our existing Eva scan. This is done at close range in hard to reach areas for fine resolution. We will capture that Angel’s face in the artwork and add that fine detail to our existing scan. With the Artec Space Spider, we’re scanning about 5.7 frames per second.
Using the Artec Space Spider for Detailed 3D Scans
Now, I’m only going to add two areas here where I want real fine detail. The Space Spider works just like the Eva, it is very simple to use. Again, this will be added to the existing Eva scan we have to get fine detail in these areas. The area of the angel [pictured above] is about 200 micron resolution, which may be fine depending on its intent of use.
Now, let’s add a line and process our previous Spider scan of just the area around the angel to add fine detail that our Space Spider is capable of. Next, we are going to align our Spider scan with our Eva scan. First, let’s click on our Spider scan and let’s hit scan color so we can see the difference here [pictured below]. We can move it away by hitting a line. We will move this Spider scan over so we could pick some pairs to align it with the Eva scan. We need three points to match up. First, we go with the right eye then the left eye, grabbing a point on each scan. After that, we’ll hit line markers so it will be aligned perfectly!
We have one more step to go. We will do a global registration and a sharp fusion. We’ll be able to export a watertight STL and finalize this operation. Now, let’s close out the aligned dropdown menu. We will go to tools and global registration. We will use the default tabs here. This is the highest-level registration possible where it brings all the scan data together. Now, in our final process, we’ll fuse together our Eva and Spider scans. We’ll go to our tools menu, hit sharp fusion and use the default tabs and hit Apply. In this process, we will fuse together all our scanned data into a single tessellated geometry.
In our next step, we’re going to export this as a watertight STL. We will hit Export Meshes, and we will make sure we choose a STL file and hit Save. On the left side is the Eva scan alone. That detail might be fine enough for its intent. Now let’s move over to the right. Look at that detailed 3D scan on the face. Now, this is the Spider paired with the Eva in the same scan. This is available for all our Artec 3D scanners family of products.
