Hackett3D recently invested in the 3D Systems ‘’Sense’’ 3D scanner. Sense 3D scanner gives us the ability to observe a scene in three dimensions and then translates the observations into multiple depth images. It then takes and combines those depth frames into a 3D model made up of thousands of connected triangles, called a mesh.
The first object we tried to scan was a runner, we tried and tested a few different techniques to catch the best possible scan.
- Using as turntable- to do this we place the runner on a turntable, had the scanner fixed to a tripod stand and moved the object. However we learnt that the scanner gathers its information from geometry of the background rather than just from the object itself. So this method could not work.
- The next attempt we placed the runner in the middle of the table and scanned around the object. This scan was successful however it did not allow for a scan underneath the runner. We also established the best way to use the handheld scanner was with the laptop for mobility and use the screen as a guide. See Figure 2&3
- From what we learnt from our previous attempts, we hung the runner from a height to allow scanner to gather information underneath the object. See Figure 4
The scan of the runner is a print ready file, so it was only a matter of pressing print on our powder based Projet 660pro and plastic PLA CubeX printers.
On the Projet660pro the print took 1 hour and 30 minutes with 90 minutes of curing time post printing. The total volume of the runner was 11 cubic centimetres.
On the CubeX the print took just over 4 hours and weighed a total of 39 grams. With CubeX we had a choice of several different coloured PLA plastics, in the end we picked the red PLA.
Overall we found the Sense 3D scanner very easy to use, the print ready files were very convenient. Whilst the scan itself was not 100% it was still very accurate. We are now looking forward to testing the full capabilities of the scanner.
