-The Sprout G2 is a hardware and software solution in an all-in-one computer. Combining HP hardware with software acquired after taking over [[http://​www.3ders.org/​articles/​20160705-hp-acquires-3d-scanning-david-vision-systems-and-david-3d-solutions.html|DAVID 3D systems]]. It it the second generation HP Sprout (G2) and includes a 3D sensor for hand-held scanning.

-====Which Sprout ​Scanning ​Technology to use?====+====Comparing ​Scanning ​Technologies====
  
-Choosing ​the whether to use the SLAM fusion or Structured Light scanning depends ​on the size of your object, the quality of your desired result and your physical capabilities (and patience!)+Below is example of the output from both technologies ​on the Sprout.

 +====Choosing a Scanning Method====
 +
 +As you can see from above, the quality of the output of the structured light is considerably higher, ​ so whether to use the SLAM fusion or structured light scanning depends on the size of your object, the quality of your desired result and your physical capabilities (and patience!). ​
  
   * If your object ​ is large enough and you want a quick result that covers all surfaces and is pre-textured,​ use the 3D SLAM fusion method.   * If your object ​ is large enough and you want a quick result that covers all surfaces and is pre-textured,​ use the 3D SLAM fusion method.
