3D Printing Technologies
We operate multiple 3D printing technologies to match your specific material requirements, precision tolerances, and budget. Not every project calls for the same process — our team selects the right technology for your application and explains the tradeoffs clearly.
From affordable FDM thermoplastics to high-resolution SLA resin, structural SLS nylon, industrial-grade FFF engineering polymers, and multi-material printing, Export Commodity’s Houston facility is equipped to handle the full spectrum of 3D printing applications. All manufactured in-house. All made in the USA.
FDM — Fused Deposition Modeling
Fused Deposition Modeling is the most widely used 3D printing technology — and for good reason. FDM printing melts and extrudes thermoplastic filament layer by layer to build strong, functional parts at an accessible price point. It’s the go-to choice for prototypes, enclosures, jigs, fixtures, and any application where cost efficiency and turnaround speed matter. FDM parts have excellent structural integrity along the XY axis and offer a broad material palette including PLA, ABS, PETG, ASA, and TPU. At Export Commodity, FDM is our highest-volume production technology — suitable for single prototypes and large batch runs alike.

SLA — Stereolithography
Stereolithography (SLA) uses an ultraviolet laser to cure liquid photopolymer resin layer by layer, producing parts with exceptionally smooth surface finishes and fine detail resolution. SLA is the preferred technology when visual quality, surface accuracy, or intricate detail is the top priority. Common applications include dental and medical models, jewelry casting patterns, architectural detail pieces, fine-scale prototypes, and any part requiring a production-quality surface without extensive post-processing. SLA parts are isotropic — meaning consistent mechanical properties in all directions — and can be further post-processed with sanding, priming, and painting for a truly finished appearance.

- Parts requiring minimal post-processing
SLS — Selective Laser Sintering
Selective Laser Sintering (SLS) uses a high-power laser to fuse nylon powder into solid structures — without requiring support material. The unsintered powder itself supports the part during printing, enabling complex geometries, internal channels, living hinges, and interlocking assemblies that would be impossible with other technologies. SLS-printed Nylon PA12 parts offer excellent mechanical properties: high impact resistance, chemical resistance, and fatigue strength. Glass-filled variants provide enhanced stiffness and dimensional stability. SLS is the preferred choice for functional end-use components, complex assemblies, and production parts that need to perform in demanding environments.
Technical Specifications
| Layer Height | 0.1mm standard |
| Tolerance | ±0.3mm typical |
| Build Volume | Up to 340 × 340 × 600mm |

- Parts requiring no support witness marks
FFF — Industrial Fused Filament Fabrication
While FDM handles standard thermoplastics, industrial FFF (Fused Filament Fabrication) systems process high-performance engineering polymers that require elevated chamber temperatures, enclosed build environments, and precision motion control. At Export Commodity, our industrial FFF machines handle PEEK, Polycarbonate, Carbon Fiber-reinforced PA, and other demanding materials with service temperatures up to 250°C. These systems also support large-format printing for oversized industrial components. If your application demands the highest material performance from a polymer-based part, industrial FFF is the answer — without the cost and lead time of CNC machining or metal manufacturing.

| Layer Height | 0.1mm – 0.4mm |
| Tolerance | ±0.2mm typical |
| Build Volume | Up to 500 × 500 × 500mm |

- Aerospace and automotive parts
- Lightweight structural replacements
- Medical device components (biocompatible PEEK)
- Large-format industrial fixtures
Multi-Color & Multi-Material Printing
Multi-color and multi-material 3D printing enables a single print job to incorporate multiple colors, textures, or material properties — without painting or assembly. Our multi-material FDM systems can print rigid structures with flexible overmolded grips, create full-color display models with detailed text and logos, or combine soluble support material with engineering polymers for complex geometries with zero support witness marks. Multi-color printing is ideal for presentation prototypes, branded display items, educational models, and consumer product mockups where visual fidelity matters as much as structural performance.
