Custom Surface Finishes for CNC & 3D Printed Parts

Equipment & Process Control

• Advanced equipment for anodizing, powder coating, electroplating, polishing, sandblasting, and painting

• Tight process control with surface roughness tolerance down to Ra 0.2 μm

Lead Time

• Typical turnaround: 5–10 business days (varies by finish type and batch size)

Applicable Materials

• CNC machined metals: Aluminum, stainless steel, titanium

• 3D printed materials: Resin, metal, plastic

For CNC Machined Metals

• Aluminum: Anodizing (Type II & III, custom colors)

• Stainless Steel: Passivation, electropolishing, chrome plating

• Titanium: Chemical passivation, anodizing (for color coding)

For 3D Printed Materials

• Resin: Surface smoothing, painting, UV curing

• Metal: Sandblasting, electropolishing, passivation

• Plastic: Dyeing (nylon), vapor smoothing, powder coating

General Finish Types

• Polishing: Mirror finish, satin finish

• Abrasive Processes: Sandblasting, bead blasting (for texture)

• Coating: Powder coating (custom colors), electroless nickel plating

Q1: What types of custom surface finishes do you provide for CNC and 3D printed parts?

A1: We provide anodizing, powder coating, polishing, sandblasting, plating, passivation, and more, tailored for both CNC machined metals (aluminum, stainless steel) and 3D printed materials (resin, metal, plastic).

Q2: Can you finish both metal and plastic 3D printed parts?

A2: Yes, our finishing services cover all 3D printed materials—resin (smoothing, painting), metal (electropolishing), and plastic (dyeing, vapor smoothing)—with material-specific processes.

Q3: What is the typical lead time for custom surface finishes?

A3: Lead times range from 5 to 10 business days, depending on the finish type (e.g., anodizing vs. powder coating) and order batch size.

Q4: Do you offer color anodizing and powder coating?

A4: Yes, we offer a wide range of custom colors for both anodizing (Type II/III for aluminum) and powder coating, matching client-specific Pantone or RGB values.

Q5: How do you ensure quality and consistency in finishing?

A5: We use advanced process controls (e.g., temperature monitoring for anodizing) and post-finish inspections (surface roughness testers), maintaining strict tolerances to guarantee consistent results across every part.
