Many different materials (known as filaments) can be used to print 3D Objects. Depending on the technology used, we differentiate the following methods:

• Melting or softening the material to produce the layers: thermoplastics (e.g. PLA, ABS), polyamide (nylon), RTV silicone, porcelain, metal clay, titanium alloys, cobalt chrome alloys, stainless steel, aluminum, metal powders, ceramic powders.
• Curing liquid materials like Photopolymers.
• Shaping and joining together thin layers (paper, polymer, metal foil, plastic film) – used in laminated object manufacturing.
