Thermoplastics:
* PLA (Polylactic Acid): A biodegradable and renewable plastic, known for its ease of use and good strength.
* ABS (Acrylonitrile Butadiene Styrene): A strong and durable plastic, often used for prototypes and functional parts.
* PETG (Polyethylene Terephthalate Glycol): A strong and flexible plastic, suitable for applications requiring impact resistance.
* Nylon: A strong and tough plastic, known for its durability and resistance to chemicals.
* PVA (Polyvinyl Alcohol): A water-soluble plastic often used for support structures in multi-material printing.
Resins:
* Epoxy Resin: A strong and durable resin used for creating durable and water-resistant objects.
* Photopolymer Resin: A resin that cures when exposed to UV light, used for detailed and precise printing.
* Silicone Resin: A flexible and durable resin, often used for creating molds or objects that need to bend.
Other Materials:
* Metal: 3D printing with metals is a growing field, using techniques like powder bed fusion and directed energy deposition. Materials include stainless steel, titanium, aluminum, and bronze.
* Ceramic: Ceramic 3D printing uses materials like clay, porcelain, and zirconia to create functional and decorative objects.
* Wood: Wood-based filaments are gaining popularity, offering a natural and sustainable alternative to plastic.
The specific materials used will depend on the application, the desired properties of the object, and the capabilities of the 3D printer.
