Pure copper reflects roughly 95% of standard 1064 nm infrared fiber laser energy at room temperature. This low absorption requires high laser intensities that can suddenly overheat the melt pool, causing severe spatter, keyholing, and porous pockets (<95% density). The 515 nm green wavelength is absorbed 8 to 10 times more efficiently by copper, enabling a stable melt pool, uniform consolidation, and densities consistently above 99.8%. This maintains the high electrical and thermal conductivity required in heat exchangers and induction coils.

As-printed LPBF components typically exhibit linear shrinkage and thermal stress deviations ranging between ±0.1 mm to ±0.2 mm. We bridge this with a hybrid manufacturing protocol: all CAD files receive added machining stock (typically 1.0 mm to 1.5 mm) on functional interfaces like bearing seats, threaded holes, and sealing lands. The printed component is stress-relieved in a vacuum furnace while still anchored to its base plate, cut free, and aligned on a 5-axis CNC mill using touch-probe datum locating to achieve critical tolerances down to ±0.005 mm.

For LPBF additive components in Ti6Al4V or 316L, unsupported vertical walls can be reliably printed down to 0.4 mm to 0.5 mm, whereas horizontal fins or overhung walls should generally remain >0.8 mm to avoid thermal sag. Conversely, in subtractive multi-axis CNC operations, aluminum walls can be milled to 0.8 mm without severe chatter if supported by proper fixturing, while stainless steel and titanium walls should typically exceed 1.2 mm to maintain geometric stability during tool engagement.

Standard delivery includes a full CMM dimensional report mapped to your drawing's GD&T callouts, complete with raw material lot certificates (EN 10204 Type 3.1). For critical structural components, we provide additional non-destructive evaluations upon request: X-ray CT (computed tomography) for internal lattice and channel continuity, liquid penetrant testing (PT) for surface crack detection, and ultrasonic density testing to confirm complete internal consolidation.

We operate with no minimum order quantity (MOQ: 1 unit). For pilot runs, we use flexible soft-fixturing and multi-axis machines to validate your part's geometry quickly without upfront tooling investments. Once the design is frozen, we move production to dedicated fixture plates, optimize CNC toolpaths, and nest multiple components in single LPBF additive builds, helping reduce unit costs and cycle times as your volumes scale.
