● Heatbed:
Use one coat of gluestick. Clean as described after the print.
10.7 Flex
Flex is a very strong and flexible
material
suitable especially for the flexible prototypes,
covers, etc.
Important:
Before you start printing from Flex, clean the nozzle from the
previous material preheat the nozzle and load PLA to remove any other previous material.
When loading Flex loosen the extruder (idler) screws. Keep in mind that when printing from
Flex the automatic filament exchange function may not work properly.
● Nozzle temperature:
230 °C
● Bed temperature:
50 °C. You can set the bed temperature up to 65 °C depending
the
size
of an object. (larger object means higher temperature)
● Heatbed:
Make sure the surface is clean as described in
6.3.2 PEI print surface
preparation
chapter. Some very soft flex materials can bond to the bed too much and
require to use glue on the bed as separator to prevent PEI damage.
10.8 Dialing in new materials
Each manufacturer produces slightly different material even though, they are under the
same group. For example Prusa PLA and ColorFabb PLA will have slightly different output
when printed.
To achieve the best possible output you should experiment with the
nozzle temperature
,
fan speed
,
print speed
and
flow
. All of these can be changed even during a print from the
Tweak
menu on the LCD panel.
Same also applies even for materials which are not listed here.
Take the manufacturer
suggested settings, find the closest match in Slic3r material profiles, modify and save as
new.
Continue by printing few simple test pieces and continuously use the Tweak
menu.
After each improvement, don’t forget to modify the settings in Slic3r. Reset the tweak
values before every print.
Don’t forget to share your settings on our forums or directly with us.
