πŸ“Œ Used for: Gears, hinges, medical implants. πŸ₯

πŸ”Ή PC (Polycarbonate) – Super Tough & Heat Resistant πŸ”₯

βœ” Incredibly strong (bulletproof glass is made of PC!) πŸ›‘οΈ
βœ” High impact & heat resistance (softens at ~150Β°C!) 🌑️
❌ Difficult to print – requires high temps (~300Β°C) and enclosure ⚠️

πŸ“Œ Used for: Helmets, protective casings, aerospace parts. ✈️

πŸ”Ή PEEK / PEI (ULTEM) – The Ultimate High-Temp Material πŸš€

βœ” Used in aerospace & medical fields πŸ₯
βœ” **Can withstand 300Β°C+ temperatures! πŸ”₯
❌ Extremely expensive & hard to print πŸ’°

πŸ“Œ Used for: Aircraft components, medical implants. πŸ—οΈ


πŸ› οΈ 3. Composite Filaments – Strength + Functionality 🦾

Composite filaments mix plastic with other materials for added strength, conductivity, or aesthetics.

πŸ”Ή Carbon Fiber-Filled Filaments – Lightweight but Super Strong πŸ’ͺ

βœ” Much stiffer & lighter than pure plastics πŸš€
βœ” Great for aerospace & automotive applications ✈️
❌ Wears out nozzles fast – requires hardened steel nozzle ⚠️

πŸ“Œ Used for: Drones, race car parts, tools. 🏁

πŸ”Ή Wood-Filled Filaments – Looks & Feels Like Real Wood 🌳

βœ” PLA mixed with wood fibers (oak, bamboo, etc.) πŸͺ΅
βœ” Can be sanded & stained like real wood! 🎨
❌ Clogs nozzles if printed too fast ⚠️

πŸ“Œ Used for: Decorative models, architectural designs. 🏑

πŸ”Ή Metal-Filled Filaments – Heavy & Realistic βš™οΈ

βœ” Contains metal powders (bronze, copper, steel) πŸ—οΈ
βœ” Can be polished to look like real metal! ✨
❌ Very dense – requires a strong extruder ⚠️

πŸ“Œ Used for: Statues, props, mechanical parts. πŸ†


πŸ”¬ 4. Resins – For High-Detail SLA Printing 🎨

Unlike FDM filaments, resins are used in SLA 3D printers to produce extremely fine details.

πŸ”Ή Standard Resin – Smooth & Detailed 🎭

βœ” Perfect for miniatures & jewelry πŸ’
