MI-3D200 3D Proto Print Fused Deposition Modeling (FDM) is a popular 3D printing technology known for its accessibility and cost effectiveness. Here’s a brief introduction to FDM-based 3D printers FDM printers use a spool of filament, usually made of PLA or ABS plastic, fed through a heated nozzle. The filament is heated to its melting point inside the printer’s nozzle. The melted material is then extruded onto a build platform in thin layers. The printer builds up the object layer by layer, with each new layer fusing to the one beneath it as it cools and solidifies. if needed, support structures can be printed alongside the object to prevent overhangs and ensure stability during printing.
