[8] All parts of the Hangprinter Version 2 are contained within a single unit which uses cables to suspend the printer within a room, allowing it to create extremely large objects over 4 meters tall.

[10] To enable 3D printers to economically use recycled plastic feedstocks to enable distributed recycling and additive manufacturing (DRAM)[11][12] several types of fused granular fabrication (FGF)/fused particle fabrication (FPF)[13] -based 3D printers have been designed and released with open source licenses.

First, a large-scale printer was demonstrated[14] with a GigabotX extruder[15] based on the open source cable driven hangprinter concept.

In 2022, a patent describing the “Sky Big Area Additive Manufacturing” (SkyBAAM) system was granted to UT-Battelle, LLC, a nonprofit corporation that operates the Oak Ridge National Laboratory (ORNL).

The RepRap project established a GoFundMe campaign to cover the legal costs in their upcoming action to challenge the patent.
