Types of Materials in 3D Printing

Thermoplastics

Thermoplastics are the most commonly used materials in FDM and SLS technologies. Some of the most popular thermoplastics include:

• PLA (Polylactic Acid): Environmentally friendly, biodegradable, and easy to print with, making it a popular choice for beginners.

• ABS (Acrylonitrile Butadiene Styrene): Known for its strength and toughness, ABS is ideal for creating durable functional parts.

• PETG (Polyethylene Terephthalate Glycol): Offers high strength, flexibility, and chemical resistance, often used for food-safe containers.

 Resins

Used primarily in SLA and PolyJet printing, resins can produce parts with excellent detail and surface finishes. Some types include:

• Standard Resin: Used for basic prototypes.

• Flexible Resin: Offers rubber-like properties for more flexible parts.

• Tough Resin: Provides durability and strength similar to ABS.

Metals

3D printing with metals, such as stainless steel, titanium, and aluminum, has gained traction in industries like aerospace and medical. These metals are typically used in technologies like SLS and Direct Metal Laser Sintering (DMLS).
