Versions

Version 0

The Hangprinter v0, also called the Slideprinter, is a 2D plotter. It was designed solely to test if a 3D version could realistically be created. File:Hangprinter version 0.jpg, Hangprinter v0

Version 1

The Hangprinter v1 uses counter weights to stay elevated. File:Hangprinter v1 first print.jpg, Hangprinter v1. Counterweights tied in at its center cylinder.

Version 2

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. File:Hangprinter 3D printer.jpg

Version 3

Version 3 of the Hangprinter has the motors and gears attached to the ceiling, making the carriage lighter.

Patent dispute

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 patent describes the core features already featured in HangPrinter, causing controversy in the open source community. The RepRap project established a GoFundMe campaign to cover the legal costs in their upcoming action to challenge the patent.
