High-Quality 3D Print Manufacturers & Products

Pure copper has extraordinarily high optical reflectivity (over 95%) in the near-infrared spectrum (around 1064 nm) used by typical fiber lasers. This causes intense optical kickback, damaging laser optics and leaving unstable, shallow melt pools with high void rates. TC Precision utilizes short-wavelength green lasers (~515 nm) which copper absorbs at rates exceeding 40%. The result is a spatter-free, stable laminar melt pool producing pore-free parts with relative densities higher than 99.95% and electrical/thermal conductivity closely mirroring pure wrought copper (C10100/C11000).

As-printed LPBF components naturally achieve tolerances within ±0.1 mm to ±0.2 mm, bounded by laser spot diameter, powder particle sizing (15-53 μm), and thermal shrinkage dynamics. For critical bearing interfaces, precision threads, fluid mating seals, and reference datums, our integrated engineering workflow adds 0.5 mm – 1.0 mm of sacrificial stock material during the additive slicing phase. Following vacuum thermal stress relieving, these surfaces are indexed on 5-axis CNC machining centers to consistently achieve linear tolerances down to ±0.005 mm and true position runouts within 0.01 mm.

Residual stress management starts before printing using thermo-mechanical finite element simulation to forecast distortion fields, select optimal build angles, and place lattice support anchors. During printing, heated build chambers (up to 200°C) reduce thermal gradients. Crucially, as-printed parts are never parted from the build plate until they undergo vacuum inert-atmosphere stress relief or Hot Isostatic Pressing (HIP) cycles, equalizing internal grain microstructures and eliminating warping before finish machining.

We operate with a strict No-MOQ policy. We support everything from a single functional validation prototype to serialized recurring bridge runs of 5,000+ units. Standard prototyping runs are delivered within 5 to 7 business days, while serialized batches incorporating post-heat treatment, CNC machining, surface anodizing or plating, and comprehensive CMM reporting typically ship within 10 to 15 working days via express international air freight.

To deliver an optimal DFM review, we request a 3D CAD model (STEP, IGES, or native Parasolid X_T) alongside a 2D engineering drawing in PDF format calling out critical GD&T, surface finishes, material grades, and thread parameters. Including operating conditions (such as pressure, thermal loads, and fluids) allows our engineering team to recommend conformal cooling geometries, topology optimization, and cost-saving material substitutes.
