Hi Sven, these videos are really helpful. Will the einscan hx and the freescan ue be able to scan gears, splines and threads? If so, what would be the smallest you recon you will be able to scan. Would be nice to see a comparison with say a Ø20mm shaft about 200mm long for example with a spline one side and a thread on the other
For the FreeScan UE you can likely scan smaller objects, as the scan experience on higher resolutions is better than with the HX. I think 20mm diameter should still work okay. the spline end should not be a big problem, the thread end may be more difficult. It will most likely be very hard to get to the bottom of the thread, so the scan will be more washed out than the real thing, but it will be recognizable as a thread and the thread pitch should be recognizable. One of the big problems with an object like that will be that you can not fix any markers to it directly, so you need to put them on the table below. Maybe I'll find time to go and get a shaft some time and scan it for a video :)
@@antonkillian4644 In a way. The problem is that for something to be scanned, both cameras need to see the (laser) light reflecting off the surface at the same time. So any deep valleys, holes, etc become very difficult to scan (in our case the deep parts of the V shaped thread). Plus, very sharp edges like the top of the thread get dulled a bit by the filtering algorithms of the softwares. So yes, I assume a trapezoidal or square thread would scan better than a v shaped one. But it is rare that a scanned thread would be used as-is in the next processes. The scan of the V shaped thread would likely contain enough info to reverse engineer the original one as well.
Small details aren't a problem, but you need to make sure there are always markers in view for the scanner to pick up. So you either need to put markers on your wood carving or put the carving on a table with markers (such as the turntable you see in some of our videos). In addition, the object you want to scan can't be too small overall or the UE can't pick it up. I generally recommend a part taller or wider than 10cm. A cube 5cm in side length would be very difficult to scan.
@@CR3DT The 5cm refers to the total part size. The scanner is more than capable of picking up geometries smaller than 5cm, but it has trouble if there isn't enough total geometry around.
Thank you so much for the demonstration and comparison of the two devices
Great video! Thank you Sven!

@@AMAcademyBayreuth That is very interesting. So square and trapezoidal threads should be scannable, the common v shaped thread not so much

@@AMAcademyBayreuth do you by any chance have an email address I can mail you few questions to?
can freescan ue7 and ue11 scan smaller objects that have more detail such as woodcarving?

@@AMAcademyBayreuth thanks...
@@AMAcademyBayreuth - how are you able to pick up the holes on the sheet metal part in your demo? Those are much smaller than 5 cm.
@@CR3DT The 5cm refers to the total part size. The scanner is more than capable of picking up geometries smaller than 5cm, but it has trouble if there isn't enough total geometry around.
want a larger object? see if you can borrow a motorcycle fairing
