11.5 Printing problems
11.5.1 Layers break and split when printing from ABS material
ABS
​ material ​ has a higher thermal expansion than other ​ materials ​ . We suggest other
materials ​ as PET, HIPS or PLA when you ​ print ​ larger ​ models ​ .
11.5.2 Models contain either too much or not enough of the filament
You can manage the
​ filament ​ ​ flow ​ during the ​ print ​ . Use the LCD­knob and choose ​ Tune ­
Flow ​ ­ xx% ​ where you can adjust the ​ filament ​ ​ flow ​ . Pronterface users can enter the value
M221 Sxx into the command line.
When you change the
​ filament ​ ​ flow ​ next ​ print ​ will use the same ​ settings ​ unless you
change it again in menu or you reset the ​ printer ​ or unplug it from the power source.
11.6 Problems with finished models
11.6.1 Model breaks and/or is easily damaged
A typical feature of larger models printed from ABS. If you have set the temperature
properly
​
, the
​
printer
​
is away from
​
drafts
​
and object
​
design
​
is right, the printed object should
not break. The easiest way to avoid breaking or overall model fragility is to choose a different
material
​ . The strongest are PET, HIPS and PLA; while PLA has low heat resistance,PET is
the firmest and has the lowest thermal expansion.
