Custom Metal Print Quotes & Manufacturing Factories

Pure electrolytic copper reflects over 95% of standard 1064nm infrared laser light at room temperature. This high reflectivity creates melt-pool instability, intense back-reflections that can damage laser optics, and widespread keyhole porosity (yielding part densities below 96%). In contrast, a green-wavelength laser (~515nm) is absorbed at rates exceeding 40%. This ensures a smooth, stable melt pool, yielding dense copper parts (>99.8% relative density) with electrical conductivity exceeding 100% IACS and thermal conductivity above 390 W/(m·K).

As-printed metal surfaces follow ISO 2768-m (or ISO/ASTM 52920 class), holding ±0.1mm to ±0.2mm depending on build orientation, support placement, and material thermal expansion coefficients. For critical functional datums—such as bearing journals, O-ring sealing grooves, interference fits, and threaded holes—we add a 1.0mm–1.5mm machining allowance during build prep and finish the features on 5-axis CNC milling and turning centers, reaching tight tolerances down to ±0.005mm.

Brokers and software-based front-ends subcontract production to third-party machine shops, adding a 30% to 60% margin and creating communication bottlenecks when engineering issues arise. TC Precision operates its own climate-controlled 3,000m² manufacturing facility in Dongguan. Customers collaborate directly with bilingual production engineers. Quotes are generated from physical parameter models rather than arbitrary automated algorithms, and rush orders can be printed, machined, inspected, and shipped via international air courier within 72 to 96 hours.

To provide a fully guaranteed quotation and Design for Additive Manufacturing (DFAM) report, please submit:

1. A 3D CAD model in native STEP (.stp), IGES (.igs), Parasolid (.x_t), or STL format.
2. A 2D engineering drawing (PDF) identifying critical tolerances, datum features, GD&T callouts, surface roughness (Ra) targets, and tapped hole callouts.
3. Material grade, intended post-processing treatments (e.g., vacuum annealing, HIP, anodizing), order batch volume, and delivery destination. Mutual NDAs are executed prior to data transfer.

For non-fatigue critical industrial components, standard vacuum stress relief and heat treatment are typically sufficient. However, for mission-critical aerospace structures, high-pressure hydrogen manifolds, or dynamic rotating machinery subject to high-cycle fatigue, Hot Isostatic Pressing (HIP)—for example, at 920°C and 100 MPa argon pressure for Ti-6Al-4V—is recommended. HIP eliminates residual internal micro-pores, raises material density to >99.95%, and restores fatigue strength to levels comparable to wrought alloy stock.

We provide comprehensive incoterms including EXW, FOB Shenzhen/Hong Kong, CIF, and Delivered Duty Paid (DDP). For prototype and bridge volumes, components are vacuum-sealed with desiccant, packed in custom foam-lined cartons or wooden crates, and dispatched via priority express (DHL, FedEx, UPS) with guaranteed 3-to-5-day transit to North America, Europe, Japan, and Australia. Our logistics group manages export filings, commercial invoices, and harmonized system (HS) classification codes.
