The following image shows the MakerBot Replicator 2 printing specifications. These specifications are identical to the Replicator 2X except for build volume, which in 2X has decreased to 9.7 L x 6.0 W x 6.1 H due to a second print head being added.
MakerBot Replicator 2 print specifications
Build volume is self-explanatory, but what's important to note are the maximum dimensions in each of the axes, as these will limit the part size and constrain orientation.
Before printing, we will have the opportunity to specify the intended part resolution—the higher the resolution, the longer the print duration.
The most important specification to note is the XY precision (11 microns) and Z precision (2.5 microns). These are absolute limits which must be considered during part design. Also, note how Z precision is over 4x that of XY. For the majority of applications, this will not make a difference; however, if you are desperately seeking a little more precision, this is a fact that can be exploited.
MakerBot Replicators uses a 1.75 mm filament. It will not accept a 3.00 mm filament and often times cheaper 1.75 mm filament will in actuality be closer to 2.00 mm and jam the extruder.
