The 3 Basic Materials

• PLA (The ideal for beginners): It is the most popular. It prints easily, has no odor, and comes in thousands of colors.

Tip: If you have a fast printer, look for "High-Speed PLA" to avoid gaps between layers.

• PETG (The durable one): It combines ease of use (like PLA) with strength. It withstands water and heat. Ideal for objects you use daily (e.g. a hanger).

• TPU (The flexible one): Like rubber! You can make phone cases, stamps, or rubber parts for modeling.

Attention: It requires a very low printing speed, unless you have a Direct Drive printer.

Materials for Advanced Users

• ASA / ABS: Very hard plastics, ideal for cars or outdoor use.

Attention: They have a strong smell and absolutely require a closed printer. ASA is preferable because it does not fade in the sun.

• Wood / Carbon Fiber: Filaments that contain wood shavings or carbon fibers. They provide an excellent texture, but they "wear out" your printer's nozzle.

Appearance matters!

• Silk: Gives a strong metallic shine. Perfect for vases and decorative items.
• Matte: Has a "matte" finish. Hides print lines very well and the result looks like factory-made plastic.
• Dual/Triple Color: The filament has two colors at the same time. The object changes color as you turn it in the light!

What to Watch Out for When Buying (SOS)

Diameter: Most printers use 1.75mm. Make sure you don’t accidentally buy 2.85mm unless you have a specific professional machine.

Moisture (The Enemy): Filament "absorbs" moisture from the air. If you hear a "crack" during printing or see bubbles, the filament needs drying. Store your filaments in airtight bags.

Roll Quality: Prefer branded filaments to ensure they are properly wound on the spool. If the filament is tangled, the print will stop halfway because the knot will get stuck!

Tip: Start with a good PLA in gray or silver color. These colors show details best and will help you learn your printer before moving on to more challenging materials!
