There are numerous types of 3D printer filaments used in Fused Deposition Modeling (FDM/FFF) printing, each with unique properties suited to different applications, strength needs, flexibility, and printing difficulty. Here are the most common ones.

1.PLA (Polylactic Acid)

Properties — Biodegradable, made from renewable resources like cornstarch; stiff but brittle; low warping; easy to print with minimal odor.

Best for — Beginners, prototypes, decorative items, toys.

Printing tips — Low temperatures (180-220°C nozzle); no heated bed required.

2.ABS (Acrylonitrile Butadiene Styrene)

Properties → Tough, impact-resistant, heat-tolerant; durable but prone to warping and fumes.

Best for → Functional parts, enclosures, automotive components.

Printing tips → Higher temperatures (220-250°C); enclosed printer recommended.

3.PETG (Polyethylene Terephthalate Glycol)

Properties: Strong, flexible, chemical-resistant; food-safe variants available; good layer adhesion; less brittle than PLA.

Best for: Mechanical parts, outdoor use, containers.

Printing tips: 230-250°C; balances ease and performance.

4.TPU/TPE (Thermoplastic Polyurethane/Elastomer)

Properties — Highly flexible and elastic; rubber-like; abrasion-resistant.

Best for — Phone cases, gaskets, flexible prototypes.

Printing tips — Slower speeds; direct-drive extruder preferred.

5.Other Notable Types

ASA — Similar to ABS but UV-resistant for outdoor use.

Nylon (Polyamide) — Very strong, flexible, wear-resistant; absorbs moisture.

PC (Polycarbonate) — Extremely tough and heat-resistant; for high-stress parts.

Composite Filaments — e.g., Carbon fiber-filled (stiffer, stronger); Wood, Metal, or Glow-in-the-dark (aesthetic effects).

Support/Specialty — PVA (water-soluble supports); HIPS (dissolvable in limonene).

Choose based on your project's needs: PLA for ease, PETG for versatility, or specialized ones for advanced requirements. Always check your printer's compatibility!
