Speed - MakerBot Replicator 2X User Manual

TEMPERATURE
If you are experimenting with different materials
or extrusion rates, you need to consider the
properties of the material you are using.
Additives in plastic, including coloring agents,
can also affect a particular filament's properties,
so if you are having trouble with a new roll of
filament, temperature might be the culprit.
Build Plate. A heated build plate helps
printed plastic objects to stick to the
printing surface without warping. If prints
are not adhering to your build plate, and you
have tried cleaning and releveling, try raising
the plate temperature a few degrees.

ABS adheres best at temperatures between
100° and 115° C. If you adjust the plate
temperature to 115° C and continue to have
adhesion problems, the problem probably
lies elsewhere.
PLA is much less likely to warp, and tends
to work well on an unheated build plate,
but having a heated plate can improve
large PLA prints by relaxing the bottom
layers. Temperatures in the 40° to 60° C
range work well with PLA. The material of
the printing surface is also a factor here.
PLA sticks well to blue tape at much lower
temperatures, but will not stick well to
Kapton tape even at high temperatures.
SPEED [Fig. 11.5]
Everyone wants their MakerBot to move
faster so they can print things more quickly.
Our default print speed is 80 mm/s, and
if you want to print faster, you might have
to adjust more settings than the extrusion
speed. Print speeds are closely tied to
temperature settings and to the mechanical
capabilities of your MakerBot.
Speed while Extruding. Speed while
Extruding controls two things: the speed at
which the extruder is moving while printing and
the speed at which plastic is coming out of the
nozzle. These speeds are the same because
that makes for the most even extrusion.
