Billed as the first low cost desktop personal fabrication device that can operate a range of CNC manufacturing processes, the FABtotum crowd funding campaign has launched on Indiegogo.  It is a machine that 3D prints, cuts, mills and scans – personal fabrication's version of the all-in-one.

An Italian startup, FABtotum is currently hosted in the business incubator district of the University of Politecnico di Milano.  Having won the 2013 S2P competition held by the Politecnico Foundation, the company is being evaluated as a university spin-off, allowing access to academic expertise and R&D facilities.

A patent relating to multiple technical solutions is pending to guard against patent trolls.  However, the full documentation and drawings will be available online and the reproduction of the FABtotum is allowed under the Creative Commons Attribution-Noncommercial-Sharealike 3.0 Unported License.  Third parties are encouraged to create and commercialize FABtotum heads to augment its abilities.

As with most personal class 3D printers, the FABtotum employs Fused Filament Fabrication.  Its build envelope is a healthy 210 x 240 x 240 mm.  The bed is removable and its leveling is assisted by automatic Z axis probe checking.

For 3/4-axis subtractive manufacturing, the FABtotum features an engraving/milling spindle motor that can machine common materials including wood, light aluminum and brass.  The unit can be switched to subtractive mode by removing and tilting the double sided printing plane, exposing the milling plane with built in fixtures to secure the work.  It is also capable of 3-axis hybrid additive/subtractive manufacturing, allowing the user to operate in dual mode without losing position.

A key component of reverse engineering, the machine's 3D scanning ability is sure to generate interest.  The FABtotum has a built-in laser scanner and Z-dimension touch probe digitizer for this purpose.

FABtotum's developers, Marco Rizzuto and Giovanni Grieco, hope the campaign indicates the maker movement is ready for an all-in-one unit.  Success would lead to community creation and continued development.  At the time of this writing, early bird pledges for a fully assembled FABtotum are still available for $849.
