| Lead Time for Complex Parts | 1-3 days | 5-10 days |
| Cost per Part (Small Batch) | $50-200 | $100-500 |
This table compares key precision parameters between metal powder-based 3D printing and CNC machining, sourced from ASTM F2792 standards. Metal powder offers better versatility for complex shapes but slightly coarser finishes, impacting post-processing needs. For US buyers, CNC suits high-volume precision runs, while metal powder reduces costs for prototypes, influencing decisions on metal powder for sale versus machining services.
Precision Levels: Metal Powder vs CNC Machining Parameters
Precision in manufacturing defines part quality and functionality, especially in US sectors like aerospace. Metal powder for 3D printing achieves resolutions down to 20-50 microns in layer thickness, per ISO 52900 standards, enabling intricate internal structures impossible with CNC. CNC machining, using multi-axis tools, delivers sub-micron accuracy but is limited to external geometries.
A practical test from Metal3DP’s SEBM printers showed Ti6Al4V parts with 99% density and ±0.05 mm tolerances, outperforming CNC’s 0.01 mm but with less waste. For buying guide purposes, evaluate parameters like sphericity (over 95% for powders) against CNC’s tool deflection issues.
Expert insight: “Spherical metal powders enhance laser absorption, boosting precision in powder bed fusion,” notes a quote from Metal3DP‘s R&D lead. In comparisons, metal powder suits organic designs, while CNC excels in flat surfaces. US manufacturers report 30% faster iterations with powders for prototypes.
Verifiable data from ASTM E466 fatigue testing confirms metal powder parts match CNC strength post-heat treatment. For custom applications, powders like CoCrMo offer biocompatibility per ISO 13485. This section highlights how precision impacts custom metal powder pricing, urging buyers to prioritize based on design complexity.
Case example: A US automotive firm used Metal3DP’s nickel superalloys for turbocharger prototypes, achieving 25% weight reduction versus CNC versions, with verified mechanical properties aligning with SAE standards. Such integrations build trust in additive methods for high-stakes projects.
