FABtotum Personal Fabricator

Hybrids WILL be the new standard fro desktop manufacturing.

From product page:

FABtotum is a multipurpose tool, the first Low Cost Desktop Personal Fabrication device that can operate a wide range of Computer controlled (CNC) manufacturing processes.
Print, Cut, Mill, Scan, Manipulate. Rinse and repeat!
A seamless interaction between the physical and the digital world.
While Current 3D printers are defined as Personal fabricators, there is so much more to personal fabrication than 3d printing alone! FABtotum allows anyone to explore the endless possibilities of a multipurpose fabrication device.
Thanks to a sturdy structure and unconventional tecnical solutions FABtotum is capable of subtractive machining without compromising 3d printing volumes or printing speeds.
Switching to subtractive mode is easy: just remove and tilt the double sided printing plane and expose the milling plane with built in fixtures to secure your workpiece.
Along with 3/4 Axis Subtractive Machining, Fabtotum is capable of 3-axis hybrid Additive / Subtractive manufacturing, meaning you can work in dual mode without loosing the position or having to move the workpiece.
  • 3D milling on light materials (Balsa, Foam, light wood)
  • PCB milling : make your own circuit boards!
  • Engraving
  • 2.5 D Profiling (cutting) on light materials (balsa,Foam,Light wood)
  • CNC Pre-Drilling
  • 4 Axis machining on light materials.
  • 4 Axis Engraving 
Digital Aquisition:
FABtotum is capable of scanning solid objects thanks to a built in laser scanner (quick scan, medium quality) and one dimension (Z) touch probe digitalizer (hi-accuracy, very slow).
Using this feature you'll be able to unlock a whole lot of potential: scan and print duplicates of solid objects, create new objects with foams or modeling clay and scan them for further editing in a modeling software of choice, or print them in additive mode or cut/mill in subtractive mode.
Most 3d scanners cannot acquire small objects (such as a coin) and a physical digitalizer cannot acquire complex objects without at least 4 axis of freedom.
FABtotum can do both.
Scanning objects means you'll never run out of stuff to print, you'll be able to experiment with shapes or reverse-engineer objects around you, scanning and then duplicating a modified version!
  • Size: 366x366x366mm
  • Printing volume (additive) : 210x240x240mm (24 % in additive mode)
  • Milling Volume (Subtractive) : 210x240x[your milling bit height] mm
  • Scan volume (optical/digitalizer) : as much as accesible (up to printing volume depending on the object shape)
  • Scan Angular resolution: from 83 to 133 steps/degree in 1/16th microstepping mode.
  • CMOS sensor: 1024x768 or above.
  • 4th axis Milling angular resolution: as "Scan Angular resolution"
  • Z layer height: from 0.10 to 0.4 mm 
  • Z level minimum increments: encoder resolution 0,00047mm (0,47 microns) in 1/16th microstepping. (3mm pitch leadscrew / 200 steps *16 * 2 gearbox = 0,000467 = approx 0.47 microns. ,less than half a micron)
