WUDFLY printing guide
You do not need a specialist machine to print a WUDFLY aircraft. A reliable modern FDM printer, lightweight PLA and the supplied print guidance are enough to get started.
01 — Equipment
Printer brand matters less than dependable extrusion and the ability to control the settings used by foaming lightweight PLA.
Most current FDM/FFF printers are suitable when they provide the following basic capabilities.
02 — Reference material
All WUDFLY aircraft printed and developed so far have used ColorFabb LW-PLA for the main airframe structure. The published airframe masses, supplied print profiles and reference part weights are therefore based on this filament.
I have found it consistent, reliable and very well suited to lightweight aircraft printing. Using the same material gives builders the closest starting point to the aircraft that have actually been assembled, tested and flown by WUDFLY.
Other foaming LW-PLA filaments may work, but expansion, extrusion behaviour, density and finished part mass can vary. When using another material, calibrate it carefully and compare the completed parts with the reference masses supplied with the aircraft.
WUDFLY is not affiliated with, sponsored by or paid by ColorFabb. It is recommended because it is the material used throughout WUDFLY development and flight testing.
Used for most of the aerodynamic structure. Foaming LW-PLA keeps the airframe light while reproducing accurate airfoils, washout and internal features.
Used where controlled flexibility or vibration resistance is useful, including thin hinges, flexible joints and selected mounting parts.
Used for harder-wearing, higher-load or warmer areas such as motor mounts, attachment points, latches and frequently handled parts.
03 — Workflow
The aircraft package gives you a tested starting point. You prepare the jobs, print the individual sections and then follow the aircraft build documentation.
Conventional sliced parts
WUDFLY aircraft use conventionally sliced components. This allows local reinforcement, low infill where required, controlled support placement and more freedom in how each part is designed.
The print profile is the starting point, but finished mass and fitment still matter. Different machines, nozzles, filament batches and environments can require small adjustments.
04 — Print jobs
A complete aircraft is split into manageable jobs. The parts can be produced progressively over a few evenings without continuously supervising the machine.
Representative BANDIT jobs
Exact time depends on the printer and settings. These examples show the scale of the main jobs in the tested BANDIT workflow rather than a guaranteed total.
Confirm the current part list and profile notes supplied with the aircraft before starting a complete build.
05 — Why print?
Printing keeps the airframe structure inexpensive to reproduce, while also making accurate small-aircraft geometry practical and repeatable.
WUDFLY airframes are glued assemblies, so the practical advantage is being able to print a fresh structure after serious damage rather than replacing the complete aircraft and electronics package.
The flight controller, motor, receiver, servos, camera and other electronics can be transferred into a newly printed structure.
Airfoil sections, progressive washout, internal wiring channels, cooling paths and mounting features can be reproduced consistently.
Once you have a suitable printer and electronics, the same setup can support replacement airframes and very different future aircraft.
A BANDIT airframe uses approximately 74 g of filament. In practical terms, a 1 kg roll can support roughly ten complete airframes while leaving allowance for calibration pieces, spare airframes and occasional failed prints.
06 — Compatibility
This is not an exhaustive list. Compatibility by specification means the machine has the basic capability required, not that every model has been personally tested by WUDFLY.
The printer used to develop and test the current WUDFLY profiles.
Have the core temperature, extrusion and control capability needed for LW-PLA.
Open-frame and enclosed options with the required basic control and temperature range.
Examples of affordable open-frame and enclosed machines with suitable capabilities.
Modern alternatives with the temperature range, build volume and extrusion control required.
Often suitable when well calibrated. Compare the resulting part weights with the supplied references.
