Replicator Dual Extrusion Machine

3D Printer.jpg


The Replicator is a 3D printer made by the MakerBot® Industries. This is a high performance FDM 3D printer with two printing heads. The dual extruders are capable of printing two materials at the same time, or two colors at the same time. It has a large big heated build platform to enable builds using ABS.

Our replicator 1 has been extensively upgraded, with steel arms and runs the SailFish firmware for superior print quality and speed. We commonly print at 100 micron, 150 micron, and 200 micron resolution per layer in both ABS and PLA.

The Replicator used to be hosted, but was purchased and is now owned by the Hackerspace.

Replicator Operation Class

Notes ( 2017-01-30 ) :

Brad Selph has completed several repairs and the machine is now operational.

Best results currently are with using Simplify 3D as the slicer (it is installed on the Windows computer next to the Makerbot).

The configuration settings file for Simplify3D with the Makerbot is on the ATXHS Storage network drive, in public -> ATXHackerspace -> 3D Printing -> Makerbot-Simplify-3D , the Simplify3D files end in extension .fff .

With ABS, the bed temperature should be 95C to 100C, depending on adhesion issues -- go higher if it is not sticking. ABS should be extruded at 220C, PLA between 200C and 215C.

You do not need to clean the build plate with every build, or necessarily re-apply hairspray.

ONLY the Garnier Products Frustic Style "Extreme Control" hairspray should be used on the glass, it is a green metal can ( or or ). The Aquanet we used to use does not spray out in an even mist any more (the newer spray cans all seem to have poor quality nozzles) and you get globby drops on the bed.
