Why Choose ABS for CNC Machining?
At 6CNC, ABS (Acrylonitrile Butadiene Styrene) is one of our most commonly machined plastics. It offers an excellent balance of toughness, rigidity, and ease of machining, making it ideal for functional prototypes and end-use parts.
ABS has good impact strength, dimensional stability, and is easy to finish with painting, plating, or silk screening. Its relatively low cost and versatility make it a top choice across many industries.
We support various ABS grades and provide one-stop CNC machining + surface finishing services.
Popular ABS Grades We Machine
ABS (Standard)
The most widely used grade. Offers good overall mechanical properties, excellent machinability, and strong impact resistance. Ideal for enclosures, brackets, housings, and general functional parts.
Typical Properties:
- Density: 1.04 – 1.06 g/cm³
- Tensile Strength: ~40 MPa
- Good impact resistance and stiffness
Flame Retardant ABS (FR-ABS)
Modified with flame retardants for improved fire resistance. Commonly used in electronics, electrical housings, and safety-critical components.
ABS+PC
Blend of ABS and Polycarbonate. Combines the best properties of both materials — higher toughness, better heat resistance, and improved impact strength. Suitable for demanding applications.
Glass Fiber Reinforced ABS
Reinforced with glass fibers for higher stiffness and strength. Used when extra rigidity or dimensional stability is required.
Surface Finishes for ABS Parts
Enhance appearance, durability, and functionality with these options:
As Machined
Clean surface straight from CNC machining. Maintains the tightest tolerances and is the most cost-effective option. Ideal for functional testing, prototypes, and internal components where appearance is not critical.
Painting & Spraying
Wide variety of colors, gloss levels (matte, satin, gloss), and textures available. Professional painting significantly improves aesthetics, UV resistance, and scratch resistance. Commonly used for consumer electronics housings and visible end-use parts.
Vapor Polishing / Chemical Smoothing
Creates a smooth, high-gloss surface by slightly melting the outer layer. Effectively removes minor machining marks and layer lines. Especially suitable for clear or high-visibility parts that require a polished, premium look.
Plating (Chrome, Nickel, Gold, etc.)
Gives ABS parts a metallic, high-end appearance. Electroplating or vacuum metallization adds a shiny, reflective surface. Popular for decorative components, automotive trim, and premium consumer products.
Silk Screening / Pad Printing
High-precision addition of logos, text, icons, or markings. Durable and cost-effective for branding. Ideal for control panels, buttons, and product identification.
Other Finishes
UV Coating: Provides extra protection against yellowing and improves surface hardness. Sandblasting / Bead Blasting: Creates a uniform matte texture and helps hide minor surface imperfections. Laser Engraving: Permanent marking for serial numbers, logos, or functional indicators. Clear Coating: Enhances gloss and protects the surface without changing the color.
CNC Machining vs 3D Printing for ABS Parts
How to Choose the Right Process
Choosing between CNC machining and 3D printing depends on your project requirements. Below is a clear comparison to help you make the best decision.
| Criteria | CNC Machining (ABS) | 3D Printing (ABS / ASA) | Winner / Recommendation |
|---|---|---|---|
| Dimensional Accuracy | Excellent (±0.05 mm or better) | Good (±0.1 ~ ±0.3 mm) | CNC |
| Surface Finish | Excellent (Ra 0.8–1.6μm, smooth) | Fair (visible layer lines) | CNC |
| Part Strength | Very High (isotropic, full material strength) | Moderate (anisotropic, layer adhesion) | CNC |
| Functional Durability | Excellent for end-use parts | Good for prototypes, limited for heavy use | CNC |
| Complex Geometries | Good (limited by tool access) | Excellent (unlimited design freedom) | 3D Printing |
| Thin Walls & Fine Details | Good (down to ~0.5mm) | Very Good | 3D Printing |
| Production Volume | Best for 1–500+ pcs | Best for 1–50 pcs | CNC (for >50 pcs) |
| Lead Time (Prototypes) | 1–5 days | 1–3 days | 3D Printing (slightly faster) |
| Cost (Low Volume) | Higher for very complex parts | Lower for 1–10 pieces | 3D Printing |
| Cost (Medium Volume) | Much more economical | Becomes expensive | CNC |
| Material Properties | Closest to injection molded parts | Slightly weaker than solid material | CNC |
| Post-Processing | Painting, plating, vapor polishing easy | Requires more sanding and finishing | CNC |
| Heat & Chemical Resistance | Excellent | Good | CNC |
| Best For | Functional prototypes, end-use parts, tight tolerances, production | Concept models, complex shapes, rapid iteration | – |
Quick Decision Guide
- Choose CNC Machining if you need: High precision, strong mechanical performance, smooth surface, functional end-use parts, or more than 30–50 pieces.
- Choose 3D Printing if you need: Very complex internal structures, ultra-fast design iterations, extremely low quantity (1–10 pcs), or highly organic shapes that are difficult to machine.
- Hybrid Approach: Many customers use 3D Printing for initial concept validation, then switch to CNC Machining for final functional prototypes or production.
