FDM is a filament-based technology that works with production-grade thermoplastics to build strong, durable and dimensionally stable parts with unsurpassed accuracy and repeatability. The thermoplastic filament is heated to its melting point and then extruded, layer by layer, onto a build platform.
How FDM works: 3D printers that run on FDM technology build parts layer-by-layer from the bottom up by heating and extruding thermoplastic filament
Pre-processing: Build-preparation software slices and positions a 3D CAD file and calculates a path to extrude thermoplastic and any necessary support material.
Production: The 3D printer heats the thermoplastic to a semi-liquid state and deposits it in ultra-fine beads along the extrusion path. A support structure is created where needed and built in a water-soluble material.
Post-processing: The user breaks away support material or dissolves it in detergent and water, and the part is ready to use
The great advantage of FDM is the durable materials it uses, the stability of their mechanical properties over time, and the quality of the parts. Companies in a variety of industries use FDM for product development, functional prototypes, specialized manufacturing tools, and detailed end-use parts.
FDM Technology uses the same tried and tested thermoplastics found in traditional manufacturing processes; for applications that demand tight tolerances or specialized properties, such as translucence or biocompatibility, there’s an FDM thermoplastic that can deliver.
