Tips for 3d printing
On this page I have listed links to my 3D printing tips and tricks videos.
When designing and producing the parts for my RC flight models, I use PrusaSlicer, which can be downloaded from https://www.prusa3d.de/prusaslicer/, to realize special desired properties for 3D printed parts. These properties (e.g. adhesive surfaces or internal support structures) cannot be achieved at all or only with great difficulty using a CAD program alone.
Prusaslicer: Extract stl-files out of 3mf-files
PrusaSlicer offers the possibility to extract stl files from 3mf
files.
You have the option of exporting the entire printing plate or extracting individual printed parts
and exporting them as an stl file.
PrusaSlicer 2.5: Strong and lightweight parts for RC airplanes with new infill patterns
PrusaSlicer offers new infill patterns since version 2.5.
In this video I show how I use these infill patterns to produce strong yet lightweight parts for my
RC model airplanes.
PrusaSlicer: Save weight by using modifiers
Weight is an important consideration when designing parts for 3D printed RC airplanes.
PrusaSlicer offers various options to save weight when designing 3d
printed parts.
In this video I show how I use modifiers to optimize the weight of a servoplate which I use in one
of my prototype planes.
PrusaSlicer: Settings to reduce stringing
Stringing is an issue especially when printing with foaming filaments like all types of LW-PLA
(lightweight PLA). With these filaments stringing can't be reduced by tuning the retraction settings
because the foaming process takes place in the nozzle of the printer. Furthermore high retraction
settings will lead to nozzle clogs.
PrusaSlicer has a lot of settings that can be tuned to reduce
stringing.
In this short video I show which settings I use to print my single perimeter parts for my RC
airplanes.
PrusaSlicer: Print multiple parts sequential in one pass
Stringing is an issue especially when printing with foaming filaments like all types of LW-PLA
(lightweight PLA). One possibility to reduce stringing is to print only one part with a minimum
amount of travel moves.
But when printing small parts heating up and cooling down the printer for every single part is quite
time consuming.
PrusaSlicer has an option to print multiple parts one after another
as whole objects. You can populate your print bed with more than one part. But you have to take care
that the printhead does not collide with allready printed parts during the printing process.
In this short video I show how I populate my print bed with parts and how I adjust the settings in
PrusaSlicer to print them out as individual objects.
PrusaSlicer: Tipps for printing in TPU
In this video I show two tips for printing in TPU (flexible filament) with my bowden-style 3d
printer.
You can also print soft TPU with a bowden-style 3d printer if you choose the filament flow through
the extruder to be constantly slow.
