Which type of printer typically uses filaments as a material?

The FDM printer, or Fused Deposition Modeling printer, typically uses filaments as its primary material for the additive manufacturing process. In FDM printing, the filament, which is usually made from thermoplastics such as PLA, ABS, or PETG, is heated and extruded through a nozzle to build up layers of the object being printed. This layer-by-layer process allows for the creation of intricate designs and geometries.

The choice of filament type is critical in FDM printing as different materials provide various properties such as strength, flexibility, and temperature resistance. The simplicity of using filament makes FDM a widely adopted technology for both hobbyists and professionals in 3D printing.

Other types of printers, like SLA (Stereolithography), SLS (Selective Laser Sintering), and inkjet printers, utilize different materials and processes. SLA printers use photosensitive resin cured by light, SLS printers use powders that are fused together, and inkjet printers typically apply liquid materials rather than solid filaments. This distinction reinforces the unique characteristics and applications of FDM printers within the broader context of 3D printing technologies.
