Replicator Dual Extrusion Machine



The Replicator is a 3D printer that was by the MakerBot® Industries. Although it was originally an FDM 3D printer with two printing heads, the current machine has been configured with a single extruder to simplify printing. It has a large heated build platform to enable builds using ABS.

Our Replicator 1 has been extensively upgraded and modified, with aluminum arms and runs the SailFish 7.7 firmware for superior print quality and speed.

The Replicator is owned by ATX Hackerspace and was rebuilt on 05/23/2019 by Martin Bogomolni.

Replicator Settings

To use the Replicator, you will need software to slice and save an .x3g file to an SD card. Please use one of the following two software packages:

[Simplify 3D] is $140, and has "plug and play" ready settings to use the Replicator.

[Cura 4.0] is free and open source software, and you will need to install a plug-in from the Cura Marketplace as well as change the start/end GCODE for the machine.

Replicator CURA Settings


Install the X3GWriter plugin by GhostWriter to automatically output X3G files
