= RepRap printers "committed to Free Software, Libre Innovation, and Open Source Hardware".




"The Lulzbot printers are developed by the small company Aleph Objects, Inc. which is committed to Free Software, Libre Innovation, and Open Source Hardware. Although the printers include some extruded aluminium railing and other mass-production components it still remains true to RepRap principles by having many components 3D printable. Due to its fully Open Source Hardware and Free Software design, the LulzBot has received the "Respects Your Freedom" certification from the Free Software Foundation. In addition, the Lulzbot printers are often used in open-source tool chains on open source projects." (




The development, assembly and use of the Lulzbot machines is facilitated by an online community forum, a project development platform (Phabricator). There is also the Open Hardware Assembly Instructions.
