Hangprinter is an open-source fused deposition modeling delta 3D printer notable for its unique frameless design. It was created by Torbjørn Ludvigsen. The Hangprinter uses relatively low cost parts and can be constructed for around $250 USD.[1][2][3][4] The printer is part of the RepRap project, meaning many of the parts of the printer are able to be produced on the printer itself (partially self replicating). The design files for the printer are available on Github for download, modification and redistribution.[5]

Version 0Edit

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.[6]

Version 1Edit

The Hangprinter v1 uses counter weights to stay elevated.[7]

Version 2Edit

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.[1][2][3][4]

Version 3Edit

Version 3 of the Hangprinter has the motors and gears attached to the ceiling, making the carriage lighter.[8]

Version 4Edit

Version 4 includes upgrades from version 3 including flex compensation, better calibration and automatic homing.[9]
