Please Read A Note from the Designer:
First of all, thank you so much for your interest and support of 3DAeroventures. I can’t tell you how
much joy I get out of designing and testing these aircraft, and the fact that you can now get joy out of
my creations just makes this calling that much more special. I dove into the R/C aircraft hobby as a 12
year old kid with my dad and it’s a passion I’ve maintained into adulthood. Part of 3DAeroventures
mission is to encourage people to not let go of the thing they were most passionate about growing up.
That’s why our motto is “Never Stop Exploring. Never Stop Questioning. Never Stop Playing.” I hope
the building and flying of this model keeps your passion for model aviation ignited. More importantly,
I encourage you to share your build and flying process with young people, hopefully igniting a fire in
them and helping to maintain and grow this wonderful hobby.
Now, on to the technical stuff. I haven't been very happy with single wall 3D printed aircraft, and after
playing with so many different materials I am now a big proponent of using multiple material types to
build a good performing and long-lasting craft. So I've totally changed my design methodology for these
planes to meet a few goals: Better printability/surface quality, Increased part strength, the ability to
print the parts in any material - PLA, ABS, ASA, PETG, and especially LW-PLA or LW-ASA, much simpler
slicing and the ability to use any slicer (like Prusa Slicer), and lower my design time so I can release more
designs each year.
I’ve accomplished those goals with the design of this Super Chipmunk. The outer walls of the parts now
print like a corrugated plastic - two single perimeter walls filled with a very low infill, anywhere between
3 - 7%. The downside is, printing this style of design in standard PLA leads to a heavy aircraft, though not
too heavy to fly well. That’s why I am particularly excited about the results I've gotten printing this
aircraft as a hybrid with LW-PLA. My first prototype is printed in PLA and the fully-loaded flying weight,
painted, came in over 4600 grams. It flies great with my recommended Leopard motor on a 6S. But contrast
that to my final prototype, printed as a hybrid LW-PLA version, which came out to 3300 grams, painted. I
highly recommend printing this design in a lighter plastic like ABS/ASA or a combination of LW-PLA and PLA.
I’d love to hear about your build and flight experience with this aircraft. You may contact me directly at
[e-mail] with any feedback or troubleshooting questions. Or post your experiences on
the 3DAeroventures Pilots Alliance Facebook Group.
Thanks again and enjoy your flight!

Step-by-Step Build Guide
Step 1. 3D Printing the Included Parts
Minimum Requirements:
200mm x 200mm x 200mm Print Bed Size
0.4mm Nozzle
Heated Bed (recommended)
Any Slicer Software
Option 1: G-Code
Transfer the included G-Code to an SD Card and run directly
on your i3 style printer using the materials we recommend. The
provided G-Code is for our recommended PLA / LW-PLA Hybrid build.
We’ve had good results with LW-PLA at 250º Celcius and standard
PLA at 225º Celcius but experiment with your printer to make sure
you achieve strong layer adhesion. If you wish to print this aircraft
from a different material, reference the included Slicer Settings PDF
and use your preferred slicer.
Option 2: Simplify 3D Factory Files
If you prefer to use Simplify3D as your slicer, open
the included Factory Files and edit the preset profiles
for your printer/material to ensure nice outer surfaces
and excellent layer bonding.
Your Options for Printing the Parts:
Option 3: STL + Your Preferred Slicer
If you prefer to use another slicer or create your own profiles
in Simplify3D, use the included STL files and reference the
included Recommended Slicer Settings PDF.

3D Printing Tips
Standard PLA Temperatures:
We see good results printing Paramount3D PLA at 225ºC
with a bed temperature of 70ºC. Experiment with your
particular printer and brand of material to ensure proper
layer bonding but you will likely land somewhere between
210 and 240ºC.
Cooling Fan:
Typically, PLA is printed with the fan set to 100%. However,
this can cause layer bonding issues when printing thin walled
aircraft. We have experienced nice , clean outer surfaces
when keeping the fan speed up to 20% without negatively
affecting layer bonding. Experiment with fan speeds set
between 0 - 20%.
ColorFabb LW-PLA
ColorFabb LW-PLA is an interesting material that uses foaming
technology to achieve lightweight, low density PLA parts. This
material is printed at a higher temperature (which causes it
to expand) and a much lower extrusion multiplier than standard
PLA. In order to determine the proper nozzle temperature and
extrusion multipler for your particular printer you can follow
ColorFabb’s instructions: https://learn.colorfabb.com/print-lw-pla/
We had good results printing LW-PLA at 250ºC at an Extrusion Multiplier of 0.4
and a bed temp of 60ºC. You will also likely combat quite a bit of stringing with
LW-PLA. We increase X/Y Axis Movement Speed to 200mm/s and run the cooling
fan at 25% to help combat stringing.

3D Printing Tips (cont’d)
Standard Materials Extrusion Multiplier (Flow):
You will need to experiment with extrusion multiplier for
your particular printer and material. You will likely land
somewhere between 0.95 and 1.05 extrusion multiplier.
Elephant’s Foot:
Try to avoid the first few layers of each print from
squishing too far outside the designed wall dimensions,
also known as “elephant’s foot”. This can be caused by
your nozzle being too close to the print bed or first layer
width set too high in your slicer. A small amount of
elephant’s foot is okay but too much will interfere with
the designed alignment aids.
Support Structures:
The “Fuse Tray 3” part of this aircraft requires
support structures and it’s recommended to
use your slicer’s auto-generated support
structures. The GCode and the Simplify3D
Factory Files already have the support structures
in place.
