Mitsubishi A6M2 Zero (rei-shiki-kanjō-sentōki), History
The Mitsubishi A6M „Zero“ was a long-range carrier-based fighter aircraft formerly
manufactured by Mitsubishi Aircraft Company, a part of Mitsubishi Heavy Industries, and
operated by the Imperial Japanese Navy from 1940 to 1945. The A6M was designated as the
Mitsubishi Navy Type 0 carrier fighter.
The Zero is considered to have been the most capable carrier-based fighter in the world
when it was introduced early in World War II, combining excellent maneuverability and very
long range. The Imperial Japanese Navy Air Service also frequently used it as a land-based
fighter.
In early combat operations, the Zero gained a reputation as a dogfighter,[3] achieving an
outstanding kill ratio of 12 to 1, but by mid-1942 a combination of new tactics and the
introduction of better equipment enabled Allied pilots to engage the Zero on generally equal
terms. During the final phases WWII, it was also adapted for use in kamikaze operations.
Japan produced more Zeros than any other model of combat aircraft during the war.

Included
1. 3MF 3D files (primary)
Used instead of STL files
3mf files can be used instead of standard STL files, but also include information about slicing
in the new version of Prusa Slicer (since version 2.4). Open them directly in the Prusa Slicer
as a project or import to the slicer of your choice. The files contain settings for printing on a
direct drive printer with dimensions 200x200x200 mm, that can be further adapted to suit
your printer. The generic settings are compatible with Prusa MK2/3/3S printers.
2. Factory files for Simplify3D slicer
contains all the necessary settings to slice the models along with suggested bed layout. We‘re
using PRUSA i3 ORIGINAL printers so you may need to adjust the basic printing parameters
to match your printer or use these files as a start point for you.
3. Printing Guide in our Help Section
Apart from this userguide, please see the Printing Guide for PrusaSlicer,Simplify3D or Cura
to find some Tips and Advice for airplane printing (Thin Wall Printing).Remember We use 0
retraction and 0.4-0.5 flow with LW-PLA.
4. Gcodes
Basic Gcodes prepared for direct use, as universal as possible. Should work on i3 style
printers, Give it a try, but we can‘t guarantee it will work on your printer. Wall thickness
should be 0.60-0.67mm.

1.Choose airplane at www.3Dlabprint.com, visit our Facebook for latest info.
Basic requirments for A6M2 Zero are 200/200/195 mm
volume, nozzle 0.4mm recommended (0.35 or 0.5mm
alternativelly). Heated bed recommended. Designed to be
printed with Polylight LW-PLA filament by 3DLabPrint.
Contact [email protected]
2. Create account, download
You will receive download link to all the zipped files to your
email right after the checkout (please check your spam folder
if not). If you are logged in with your account while purchasing
the model, you will find the download link in your account’s
Downloads section on our website. Please contact
[email protected] if you have trouble getting the files.
3. Prepare Gcodes
option A Gcodes
if your printer is i3 comptatible you can use prepared gcodes directly. Just save them to the
SD card and let the 3d printer do it‘s job. HE temperature is set to 240°C so the layers fuse
together well, you can adjust speed and temperature only through your printer‘s LCD. If these
Gcodes does not work for you, please proceed to the next options.

page 10
... print your plane | www.3DLabPrint.com
option B Factory files Simplify3D
We prepared all you need in these files (FFF process settings, parts layout on bed, etc...)
You can use these settings as a start point. Adjust according to your need (adapt for your
printer), print single parts and so on... Most 3d printers should work just with these settings,
but please go through the settings and amend if necessary, we are not liable for any damage
resulting from using our settings. If this still does not work for you, please proceed to the
next option.
option C Prusa Slicer 3mf files (recommended)
Please follow the guide in the Help section of our website about Prusa Slicer setup. At the
time of publishing this guide you need to download the latest 2.4-beta version from the
Prusa Slicer GitHub as previous stable version doesn’t support the Even/Odd slicing mode
yet. Don’t worry, it won’t interfere with your installed stable version as it lives in a separate
workplace.
Drag and drop the 3mf file to the Prusa Slicer window and open it as a Project. It will create
a Generic 3DLabPrint printer, printing profile and materials. Please use these as a starting
point instead of your printer profiles provided by your printer manufacturer. Strong thin-
wall printing is a dierent discipline than printing Benchys what are the stock profiles usu-
ally optimized for. Once you tweak your profiles (retractions, etc.) you can easily switch the
profile everytime you open the 3mf file. All the slicing tweaks, such as added top/bottom
layers etc. are stored in the models below, so it won’t be overwritten.
Remember We are using 0.5 multiplier and 0 retraction with LW-PLA.
3MF

... print your plane | www.3DLabPrint.com
option D CURA or MatterControl
MatterControl and CURA are free and provide satisfactory results. The airframe is still strong
enough, but don‘t expect the best quality. Both slicers lacks some very useful features, and
finer settings, like multiple processes according to Z height, retraction options, layer start,
etc.
Please try to find the best extrusion multiplier and temperature for good weight and best
possible layer bonding. Look at parts weight list for proper multiplier settings.
As a starting point you can use our predefined CURA or MC slicer setting file - see below
(always adapt it for your printer, change build volume, filament diameter, etc...
according to your printer!!!)
Please check our CURA guide on the website for the latest basic profile. Please visualise our
presliced gcodes to see how the result should look like and try to achieve the same in your
slicer. Remember We are using 0.5 extrusion multiplier and 0 retraction with LW-PLA.

4. Print it
Save the Gcodes to the SD card and insert into your printer. Prepare your printer and start
printing, we prefer to use SD card rather than direct USB connection. Scaling the model will
lead to unusable result!
you will need LW-PLA filament - (Polylight LW-PLA)
3DLac, Strong hair spray, PEI or your favorite adhesive bed surface
Razor blade
AND... please watch our VideoGuides
Basic Tips and Advice
While stadard PLA filament could be used, this plane has been designed to be printed from
foaming LW-PLA that means about 50% weight reduction on printed parts.
Please Experiment with temperature and extrusion multiplier (0.60-0.67mm Wall thickness).
Hotend temperature is very important (220° up to 260° celsius). The temperature determines,
how much the LW-PLA foams while printing. Cranking up temperature means, you can go
lower on multiplier as the material will gain on volume. Turn OFF cooling fan for better layer
adhesion (HE fan should be ON). We dont need it for thin wall printing. Heated bed is very
recommended, 55-60° Celsius (to prevent warping ends).
Price of the LW-PLA may look a bit steep at first glance, but since we’re using 50% less
material thanks to the foaming feature, the cost dierence is not so high as it looks.
Please see the Printing Guide (Help Section)

Enjoy the fun together!
A6M2 Zero is the next of new LW Planes
series designed for easy and cheap flying. The
build is simple even for a beginner. It’s very low
weight, easy assembly and fantastic flight
characteristics makes this model an ideal plane
for beginner RC pilots.
Very suitable for dads and kids. Children will learn
some modern building skills and technology and
most of all have fun. This is the reason, why every
dad should have a 3D printer at home.
This model has been completely designed with
the new PolyLight LW-PLA material in mind.
Parts printed from this LW-PLA are light, easily
sanded and glued together. This model requires
only about 220 g of this material, that means it’s
a very cheap build. In case of accident, parts can
be easily reprinted with just a filament cost.
We’ve been testing this material for half a year
before this plane was released... The material is
using an active foaming technology to achieve
lightweight, low density PLA parts. At around
230°C this material will start foaming, increasing
its volume by nearly 3 times.
All parts of this plane should be printed from LW-
PLA except the cowling motor mount and el.
Arm.
Possibly A6M2 Zero can be printed from normal
PLA but the plane will be too heavy for relaxed
flying. Standard PLA printed model therefore
could not be recommended for beginners. You
should use heavier battery also to compensate
Center of Gravity of the plane in this case.

How to print PolyLight LW-PLA?
The basic print setup is almost the same as we use for standard
PLA. The only dierence is in extrusion multiplier set to 0.5 and
turning o the retractions completely.
This results in parts with half the weight and still suitable
mechanical properties, this model is designed mainly in VASE
mode, even that expect some stringing inside and outside in
some inpossible spots. Of course you can try to tweak the
retractions for less stringing inside the parts, but there‘s a high
risk of clogging the nozzle or throat. Increasing the retraction
distance above 1 mm is not recommended at all and leads to
nozzle clogs caused by foaming. Cleaning the hairy, but
functional parts after printing with retractions completely
disabled seems to be more ecient method. The nozzle is
permanently pressurized and you don‘t need to worry about
print failures. This method works fine even for bowden
printers.
Extrusion multiplier 0,5 has been tested for easy print with
massive weight saving around 50%. Feel free to experiment
with extrusion multiplier and temperatures at will for the best
results on your printer. This airplane is designed for
0.60-0.67mm Wall thickness.
Cosmetic issues of the prints are easily fixed with snap knife or
sand paper, as the LW is easily sanded and cut.

5. Assembly of printed parts
5.1 Wing assembly A6M2 Zero
Glue wing parts L1-L4 perfectly together. The new 3DLabPrint lock system will help you.
Repeat for the right side. Glue both halves of the wing together. Use the CA glue, (position
locks and wing pins will help you to align the parts), and use activator to speed up the glue
curing. Press in and glue a piece of PolyAir, PLA or 1.5 mm carbon rod into the top and
bottom openning to create a wing spar and improve the rigidity of the wing.
On a flat surface glue the ailerons L1-L3 and repeat for the right side. Use a filament or
suitable 0,8mm - 1,5mm carbon rod as a hinge for the ailerons. Just slide it in, there‘s no need
to glue the hinge for easy aileron or servo replacement. Wall thickness should be 0.60-0.67

5.2.1 Fuselage assembly A6M2 Zero
You can use snap knife for cleaning the surface of printed parts, but mostly it is not necessary.
Glue fuselage parts F1-F4 with CA glue together. The new 3DLabPrint lock system will help
you.
Check the alignment of F4 part compared to the wing before glueing. Do not glue rudder
part before tail and elevator assembly. Use any hot tool to remove the unnecessary material
from F4 tail part for the elevator arm.
Insert two 110 mm long 3 mm diameter carbon rods making a rubber band wing holders. No
need to glue it for easy replacement. Wall thickness should be 0.60-0.67.
For fuselage cover arm use a ball pen spring. Put it to the part 2 and glue with part 1 together.
NOTE Don‘t glue the rudder tailpart yet !!! (proceed to the next step for elevator and

5.2.2 Fuselage tail - elevator pushrods and servos
Glue L1 and L2 parts of the stabilizer and elevator. The profile is symmetric, so the left and
right sides are identical. Glue the stabilizers perfectly perpendicular to the fuselage. Assemble
both sides of the elevator with the elevator control lever on a flat surface. Make a Z bend on
the elevator 0,8 mm pushrod wire. Using hot tool cut loose the hinge of the elevator on the
F4 part of the fuselage and mount the elevator assembly to the stabilizer using the 0,8 - 1,2
mm carbon rod or steel wire. Elevator should move freely controlled by the pushrod and
servo. Check the functionality of the elevator assembly carefully and finally glue in the rear
rudder part. Wall thickness should be 0.60-0.67

you will need Your own Rx/Tx system (refer to your R/C system userguide for setup)
4x rubber bands
Install your reciever, connect battery, setup servos and etc. with your trasmitter, check servo
position, then install propeller, the supplied spinner guarantees proper cooling of the motor
and mount.
Make sure the battery is positioned properly and secured with wing battery holder, if battery
moves during flight it can shift the center of gravity backwards and aircraft will become
uncontrollable! Never set ESC with propeller installed, this could be very dangerous!
9. Go flying
Pre-flight check center of gravity is very important (move it 5mm forward for the first flights),
battery properly charged, ailerons and elevator deflection check, your own flying skills or RC
simulator training ...

... print your plane | www.3DLabPrint.com
10. Pilots Please Attention!
For the first flights we recommend setting the center of gravity to around 5 mm forward of
the CG tag - nose heavy, this increases the stability (you can use heavier battery). Increasing
expo settings on your transmitter for elevator and ailerons to 80 % calms response from your
stick inputs. Also you can decrease elevator and ailerons deflection to calm down the plane.
Make sure the battery is well fixed in proper possition. If it moves during flight it will cause
shifting of CoG aft and will result in uncontrolable flight behavior.
After gaining some confidence you can balance the plane to the Center of Gravity marks and
set Expos to 60 % as shown in the video/instructions... this gains back extra maneuverability.
Never fly aft positioned Center of gravity.
