Industrial 3D printing support for prototypes, large-format parts, engineering materials, batch production, high-detail resin parts, powder-bed nylon, binder jetting, and metal additive manufacturing. We work across six core processes to match the right technology to your application.

FDM uses thermoplastic filament to build durable plastic parts layer by layer. It is usually the most practical process for functional prototypes, fixtures, housings, and short-run parts where cost, turnaround, and material toughness matter more than cosmetic surface finish.

Materials: PLA, PETG, ABS, ASA, TPU, Nylon, Polycarbonate blends, Carbon-fiber-filled polymers, Glass-filled polymers, and high-temp engineering materials.

Best for: Functional prototypes and fit-check parts. Jigs, fixtures, brackets, housings, and guards. Short-run plastic production without tooling. Engineering-material parts where strength or heat resistance matters.

Large-Format FDM takes the practicality of filament printing and scales it for oversized parts. It is useful when the part is too large for normal desktop or benchtop machines, or when tooling and full-scale prototypes need to be made quickly without machining or mold tooling.

Materials: PETG, ABS, ASA, Nylon, Carbon-fiber-filled materials, Glass-filled materials, PC blends, and engineering thermoplastics.

Best for: Large prototypes, mockups, and fit-check assemblies. Foundry patterns, molds, tooling, and shop-floor aids. Large fixtures, robotic tooling, and manufacturing supports. Enclosures, covers, panels, and oversized functional parts.

SLA and related resin processes use light-cured photopolymer resin to produce smooth surfaces, crisp details, and small features. It is often the right fit when a part needs to look polished or capture fine geometry that FDM would struggle to reproduce cleanly.

Materials: Standard resins, Tough/durable resins, Flexible resins, High-temperature resins, Clear resins, Castable resins, and application-specific photopolymers.

Best for: Visual prototypes and presentation models. Small parts with fine features and smooth surfaces. Master patterns, fit checks, and form studies. Parts where cosmetic finish matters more than raw toughness.

SLS uses a laser to fuse polymer powder into strong nylon parts without traditional support structures. It is a strong fit for functional prototypes and batch quantities where durability, complex geometry, and consistent nylon performance are important.

Materials: Nylon 12 / PA12, Nylon 11 / PA11, Glass-filled nylon, Carbon-filled nylon, TPU, and specialty powder materials.

Best for: Functional nylon prototypes and end-use parts. Batch quantities with no hard tooling. Clips, snap-fits, hinges, lattices, and complex geometry. Parts that need better all-around strength than typical FDM orientation allows.

Binder Jetting selectively bonds powder material to create parts, molds, or cores. Depending on the material system, it can be used for metal components, sand casting molds and cores, ceramic-like parts, and higher-volume additive production strategies.

DMLS (Direct Metal Laser Sintering) is a metal additive manufacturing process for producing fully dense metal parts. It is available as part of Relay's service offerings for applications that require metal 3D printed components.
