Finding 3D Models

A 3D model file (typically .STL or .OBJ) is required. Sources include:

• Thingiverse: (www.thingiverse.com) A vast library of user-created 3D models.
• Printables: (www.printables.com) Offers a variety of downloadable 3D printable models.
• MyMiniFactory: (www.myminifactory.com) Features curated, high-quality 3D models.
• Cults3D: (cults3d.com) A marketplace with both free and paid 3D models.
• Self-Design: Design your own using software like Fusion 360, Blender, or Tinkercad.

Material Choice

Choosing the correct material impacts performance, durability, and the overall quality of your print. We offer:

• PLA (Polylactic Acid):
  • Pros: Affordable, wide color range, good rigidity and strength for its weight. Easy to get good-looking prints. Biodegradable and made from renewable resources.
  • Cons: Can be brittle under impact, relatively low heat resistance.
  • Best for: Prototyping, general-purpose parts, models, and decorative items not subject to high stress or heat.
• PETG (Polyethylene Terephthalate Glycol):
  • Pros: Stronger and more durable than PLA, better heat resistance, some flexibility, less brittle. Resistant to UV and many chemicals.
  • Cons: Can be slightly more expensive than PLA.
  • Best for: Functional parts, mechanical components, outdoor applications, and parts requiring higher strength and durability.
• TPU (Thermoplastic Polyurethane):
  • Pros: Flexible, rubber-like, excellent impact resistance.
  • Cons: Flexibility makes it less suitable for rigid structural components.
  • Best for: Items requiring flexibility and impact absorption such as gaskets, seals, phone cases, and protective bumpers.
• LW-PLA (Lightweight PLA):
  • Pros: Extremely lightweight (up to 50% lighter than PLA) due to foaming.
  • Cons: Reduced strength compared to regular PLA.
  • Best for: Weight-critical applications, such as parts for drones and RC aircraft where minimizing weight is crucial.

Material Choice for FPV and RC

The above materials are used for FPV and RC aircraft parts in these ways:

• PLA: Indoor RC models and drone parts that don't require high impact resistance.
• PETG: Drone frames, landing gear, outdoor RC models, and parts exposed to sunlight.
• TPU: Vibration dampeners, bumpers, flexible joints, camera mounts, RC car tires.
• LW-PLA: Weight-critical applications, indoor flyers, slow-flying drones, lightweight wings or fuselages for RC planes.
