Fused Deposition Modeling — the world's most widely used 3D printing process. Export Commodity runs professional-grade FDM with engineering materials, tight tolerances, and post-processing options that leave hobby-grade printers far behind.
Get an FDM Quote Compare TechnologiesFused Deposition Modeling (FDM) — also called Fused Filament Fabrication (FFF) — is an additive manufacturing process that builds parts by extruding thermoplastic filament through a heated nozzle, depositing material layer-by-layer on a build platform. As each layer cools and solidifies, the next layer is deposited on top, bonding through heat and pressure to create a solid three-dimensional part.
FDM is the most cost-effective professional 3D printing technology for most applications. It's exceptionally versatile in material selection — from commodity PLA to engineering-grade Nylon, Polycarbonate, and fiber-reinforced composites — and scales economically from a single prototype to hundreds of production parts. Build volumes are large compared to resin-based technologies, making FDM the default choice for enclosures, structural parts, functional prototypes, and large props.
Export Commodity operates professional-grade FDM printers with enclosed, temperature-controlled build chambers. This is critical for engineering materials like ABS, Nylon, and Polycarbonate, which require a controlled thermal environment to prevent warping and delamination. Our machines are not the desktop FDM printers you'll find in makerspaces — they're production-grade systems with precise temperature management, filament drying systems, and calibrated extrusion that produce repeatable, reliable results.
Material selection is the most critical decision in FDM printing. We carry a comprehensive material library and will recommend the right choice based on your part's function, environment, and appearance requirements.

Parts that need to be tested for function, fit, and assembly. FDM's wide material selection means we can prototype in the actual material class of the final part — a Nylon prototype behaves like a Nylon production part.
Electronics enclosures, control panels, sensor housings, and custom equipment cases. FDM's large build volume and structural material options make it the preferred technology for enclosure work.
Inspection fixtures, assembly aids, drill guides, and production tooling. FDM in carbon-filled materials or Nylon produces rigid, dimensionally stable fixtures at a fraction of the cost of machined alternatives.
FDM's large build volumes and low per-unit cost make it ideal for props, presentation models, and architectural pieces where fine surface detail is less critical than size, strength, and cost efficiency.
Low-to-medium volume production of parts that don't justify injection molding tooling costs. Consistent quality, repeatable dimensions, and engineering material options make FDM viable for real production use.
Legacy parts, discontinued components, and custom replacement pieces for equipment and machinery. FDM can produce replacement parts on demand, often within 24–48 hours of receiving or creating the model file.
Progressive sanding from 120 to 2000 grit removes visible layer lines. Filler primer seals the surface for painting. ABS parts can also be acetone-vapor smoothed for a near-injection-molded surface finish.
Primer, base coat, color coat, and clear coat in matte, satin, or gloss. Color matching to Pantone, RAL, or reference samples. Durable automotive-grade finishes for parts that need to handle rough use.
Heat-set brass threaded inserts installed for strong, lasting threaded connections in plastic parts. Far more durable than printed threads for repeatedly assembled joints. Available in M2 through M10 sizes.
Support structures removed and support contact points cleaned. Breakaway supports leave minor surface artifacts that we clean and blend. Soluble PVA supports dissolve cleanly for zero surface impact.
FDM (Fused Deposition Modeling) works by heating a thermoplastic filament to its melting point and extruding it through a precision nozzle onto a build platform. The nozzle moves in X and Y to trace each layer's cross-section, then the platform drops (or nozzle rises) by one layer height and the next layer is deposited. The process repeats until the complete 3D object is formed from bottom to top.
Choose FDM when: (1) you need a large part, (2) you need engineering materials like Nylon, ABS, or PC, (3) cost is the primary driver, or (4) you're making functional parts that don't require ultra-fine surface detail. Choose SLA when surface finish and detail are paramount. Choose SLS when you need support-free complex geometry or high-volume production in Nylon.
FDM parts are anisotropic — they're strongest in the XY plane (along layer lines) and weaker in Z (across layer lines). For most applications, this is acceptable. The strength can be improved by increasing wall count and infill density. For load-bearing structural applications, we orient parts to align layer lines with the primary stress direction, and may recommend SLS Nylon for critical structural applications.
Yes, with the right material. PLA degrades in prolonged UV and heat exposure — not recommended for outdoor use. ASA is specifically formulated for outdoor applications, offering excellent UV resistance and thermal stability. PETG and ABS perform moderately outdoors. Carbon-fiber-filled materials add structural rigidity for outdoor structural applications. We'll always recommend the right material for your environment.
STL is the universal standard. We also accept STEP, OBJ, 3MF, and most CAD formats. If you only have a concept or a physical part, our design team can model it for you. Files can be submitted via email, shared drive link, or our online quote form.
