When 3D Printing Beats Traditional Manufacturing

3D printing isn't always the answer — but when it is, the savings in time and cost are dramatic.

⚡

Rapid Prototyping

Go from CAD to physical part in 24–72 hours. Test fit, form, and function before committing to expensive tooling. Iterate 3–5x faster than with CNC or molding.

Best tech: SLA, FDM, SLS

🔧

Complex Geometries

Internal channels, lattice structures, organic shapes, and consolidated assemblies that are impossible to machine or mold. No tooling, no compromise on design.

Best tech: DMLS, SLS, MJF

📦

Bridge & Low-Volume Production

Need 50–5,000 parts while your injection mold is being built? MJF and SLS produce production-quality nylon parts without tooling investment.

Best tech: MJF, SLS, Binder Jetting

3D Printing + Traditional Manufacturing

Dewin's unique advantage: we combine additive manufacturing with CNC, injection molding, and die casting under one roof. Start with 3D printing, scale to traditional production seamlessly.

🔄

Prototype → Production Path

3D print prototypes to validate your design. When you're ready for production, we transition to CNC machining, injection molding, or die casting — same engineering team, same quality standards.

🔧

How fast can I get 3D printed parts?
As fast as 24 hours for simple FDM or SLA parts. SLS and MJF prototypes typically ship in 2–3 business days. Metal DMLS parts take 5–7 business days. Rush service is available for all technologies.
What materials are available for 3D printing?
Plastics: Nylon PA12, PA11, PA12-GF, TPU, ABS, PLA, PETG, Polycarbonate, Accura resins. Metals: Stainless Steel 316L, 17-4PH, Titanium Ti64, Aluminum AlSi10Mg, Inconel 718, Cobalt Chrome. Specialty: PEEK, ULTEM, carbon fiber composites.
Is 3D printing suitable for production parts?
Yes, especially with MJF and SLS. HP Multi Jet Fusion produces isotropic nylon parts with consistent mechanical properties at volumes of 100–10,000+. Metal binder jetting is cost-effective for stainless steel production parts. We also use 3D printing for bridge production while injection mold tooling is being built.
How accurate are 3D printed parts?
SLA: ±0.05mm. SLS/MJF: ±0.1mm. FDM: ±0.15mm. DMLS metal: ±0.05–0.1mm. Post-machining is available for critical tolerances on metal printed parts.
How does 3D printing pricing compare?
For 1–50 parts, 3D printing is typically 50–80% cheaper than CNC machining for complex geometries. Vietnam-based printing saves an additional 30–50% vs US service bureaus. A part that costs $85 at Xometry or Protolabs often runs $35–55 through our network.
Can you print large parts?
FDM: up to 1000 × 1000 × 1000mm. SLA: up to 600 × 600 × 400mm. SLS/MJF: up to 380 × 284 × 380mm. DMLS: up to 400 × 400 × 400mm. For larger parts, we can split and bond assemblies.
Do you offer post-processing and finishing?
Yes — vapor smoothing, dyeing, painting, sandblasting, tumbling, CNC machining of critical features, heat treatment for metal parts, anodizing for aluminum prints, and assembly. We deliver finished parts, not raw prints.
