Fused Deposition Modeling or FDM printing is a 3D printing process that builds parts layer by layer from the bottom up by heating thermoplastic filament. The 3D printer heats the thermoplastic to a semi-liquid state and deposits it in fine beads along the extrusion path. Where support or buffering is needed, the printer deposits a removable material that acts as scaffolding. Resolution and side wall definition can be adjusted by selecting either the standard extrusion nozzle diameter or a fine nozzle. Using the fine (smaller diameter) nozzle does increase build time, but provides better build resolution.
FDM printing provides a wider range of materials than SLA.
Materials that can be used are:
CF-PLA [Carbon Fiber Infused]
Tech-G PETG [FDA Approved Food-Grade Filament]
HTPLA [High Temperature]
PLA/PHA [Strong Biodegradable]
TPU [Thermoplastic Polyurethane--Flexible]
Metal finishes-Brass, Copper, Bronze, Stainless Steel
Electrically Conductive PLA
More materials available upon request.
3D Printing is a more cost effective option for applications that don’t require extreme tolerances. Our printers can print at 50-100 microns.
Examples of FDM printing:
(Parts have had any necessary supports removed, but no other clean up.)
