3D Scanner/Flat-Bed Scanner

 

WHAT IS IT?

3D Scanner

  • A 3D scanner is a device that collects distance measurements from an object and uses the data to construct a three-dimensional model of the object.
  • The NextEngine 3D Scanner Ultra HD creates clean and accurate surface data while also being straight-forward and easy to use.

Flat-Bed Scanner

  • A flat-bed scanner is an optical scanner that uses a flat, glass surface to scan documents.
  • The Epson Perfection V700 Photo Flat-Bed Scanner provides high-resolution images perfect for photography.

 

WHAT CAN I DO WITH IT?

3D Scanner

  • The 3D Scanner allows for creating duplicate models through CAD software (Rhino3D, Autodesk 3DS Max, Blender, etc). 
  • Create copies of real-life objects, preserve rare artifacts, and modify pre-existing designs.

Flat-Bed Scanner

  • The flat-bed scanner allows for the preservation of photographs and archived documents in a web-friendly format.
  • The 6400 dpi resolution allows for high-resolution scans making photo editing easier.

 

SPECIFICATIONS

3D Scanner

  • Source: Twin arrays of four, Class 1M, 10 mW solid state lasers with custom optics 650 nm wavelength. Beam is about 1/1000th brightness of a laser pointer (but avoid looking into the beam).
  • Sensor: Twin 5.0 Megapixel CMOS image sensors.
  • Photo surface: Optically synchronous 7-color surface capture for precision-locked geometry correlation.
  • Photo Lighting: Built-in spatially diverse white-light illuminators with tri-phosphor, wide color gamut
  • Object Size: No preset limit. Objects larger than field can be assembled with supplied software.
  • Field Size: 5.1" x 3.8" (Macro) and 13.5" x 10.1" (Wide). ProScan Extended Mode 22.5" x 16.75".
  • Capture Density: On target surface capture up to 268K points/in² (Macro), 29K points/in².
  • Acquisition Speed: 50 000 processed points/sec throughout. Typically 2 minutes per scan of each facet.
  • Format Options: Scans can be output as STL, OBJ, VRML, XYZ, and PLY files.

Flat-Bed Scanner

  • Max Supported Document Size: 8.5 in x 11.7 in
  • Supported Document Type: Transparencies, plain paper, film
  • Optical Resolution: 6400 dpi x 9600 dpi
  • Color Depth: 48-bit color
  • Grayscale Depth: 16-bit (64K gray levels)
  • Image Resolution: 300 dpi/600 dpi

How to use it?

3D Scanner

  • Open the ScanStudio software located on the desktop.
    • Allow time for the software to recognize the 3D scanner.
  • Place your model onto the scanning surface and allow for enough slack on the cable that connects the scanning surface to the 3D scanner.
  • Pressing the Output button will bring up an additional options menu where you can set the parameters that match your object.
    • The Wide setting works best for most objects while the Macro setting is preferred when scanning objects that are smaller and closer to the 3D scanner.
  • Once you have made your adjustments in the menu, begin your scan by pressing the Start button.
  • After your scan has completed, use the included tools in the top options bar to remove any imperfections and make other required changes.
    • The Fill tool can seal any holes within the print that are unwanted.
    • The Buff tool can smooth irregular surfaces.
  • Export your print by pressing the Output button once you are satisfied with the quality of your scan. 

 

PROCESSING

  • ScanStudio performs 4X over sampling on your data.
  • Your scan data is captured as a set of XYZ points which are then automatically converted into a mesh surface comprised of triangles. This surface can have any texture applied to it, including the photographic color image of the object's surface that's captured synchronously during scanning.
  • Objects are captured with a series of views from different sides. To combine these views into a single integrated model, the facets are located within a coordinate system so they can be assembled relative to one another.
