Metal Prototyping

Speed & Cost Efficiency

Rapid metal prototyping dramatically accelerates product development by producing complex metal parts in just days instead of weeks or months. It also improves cost efficiency by allowing teams to identify and fix design flaws early, significantly reducing the risk and expense of mistakes in later production stages.

Surface Finishing

Metal Finishing

Metal surface finishing refers to a variety of industrial processes used to alter the surface of metal parts to achieve desired properties such as improved appearance, enhanced corrosion resistance, better adhesion for coatings, or specific surface textures.

Common goals include increasing durability, reducing friction, removing surface defects, and achieving aesthetic appeal.

Popular Finishing

Mechanical Finishing: Grinding, polishing, buffing, and brushing
Chemical Finishing: Etching, pickling, and passivation
Electrochemical: Anodizing, electroplating, and electropolishing
Coating Processes: Powder coating, painting, and PVD/CVD
Abrasive Blasting: Sandblasting, shot peening, and bead blasting

Benefits of Finishing

Proper surface finishing significantly improves:

Corrosion Resistance – Protects against rust and oxidation
Wear Resistance – Extends the lifespan of components
Aesthetic Quality – Creates mirror-like, matte, or textured finishes
Functional Performance – Reduces friction, improves conductivity, or enhances paint adhesion
Cleanability – Important for medical, food, and pharmaceutical applications

Common Metal Machining Materials

Metal CNC machining delivers high-precision parts with excellent repeatability. Material choice is critical as it directly impacts machinability, tolerances, cost, and performance. Higher machinability ratings mean easier cutting and better finishes. Aluminum offers the best overall balance, steels provide strength, and titanium excels in demanding uses at higher cost.

Material	Machinability	Typical Tolerances (CNC)	Common Applications	Notes / Engineering Considerations
Aluminum 6061-T6	Excellent (≈90-100% baseline)	±0.005" standard (±0.127 mm); tighter ±0.001" possible	Aerospace, automotive, consumer electronics, frames, brackets	Versatile, good corrosion resistance, weldable, lightweight. Excellent all-round choice for prototypes and production. Loses temper in heat-affected zones if welded.
Aluminum 7075-T6	Good (≈70-80%)	±0.005" standard; ±0.001"-0.002" achievable	Aerospace structural parts, high-stress components	Higher strength than 6061 but more expensive and slightly harder to machine. Prone to stress corrosion cracking in some environments.
Carbon Steel 1018	Good (≈70-80%)	±0.005" standard	General machinery parts, shafts, gears, jigs	Low cost, excellent weldability and formability. Moderate strength; requires surface treatment for corrosion resistance.
Alloy Steel 4140	Moderate (≈55-70%)	±0.005" standard	Gears, shafts, high-strength components	Heat-treatable for high hardness/strength. Good fatigue resistance but more tool wear than mild steel.
Stainless Steel 303	Good (≈70-80%)	±0.005" standard	Food processing, medical, fittings	Free-machining variant of 304. Excellent corrosion resistance.
Stainless Steel 304/316	Moderate-Poor (≈35-45%)	±0.005" standard; tighter possible with care	Medical, marine, chemical processing, food equipment	Work-hardens rapidly; requires sharp tools, lower speeds, and good coolant. 316 offers better corrosion resistance (esp. chlorides).
Brass C360	Excellent (≈100%+ reference)	±0.005" or better	Fittings, valves, decorative parts, musical instruments	Outstanding machinability and surface finish. Good conductivity and corrosion resistance. Lead content in free-machining grades.
Copper (e.g., C101)	Good (≈80-90%)	±0.005" standard	Electrical components, heat exchangers	High thermal/electrical conductivity. Soft and gummy; can cause tool buildup. Expensive.
Titanium Ti-6Al-4V	Poor (≈20-30%)	±0.005" standard; requires precision setups	Aerospace, medical implants, high-performance parts	Exceptional strength-to-weight and corrosion resistance. High tool wear, heat generation; needs rigid setups and proper coolant. Very expensive.
