Rapid Prototyping Services: Process, Cost, Lead Time & How to Choose the Right Method
Rapid Prototyping: Which Process Is Right for Your Project?
Rapid prototyping is not a single process — it includes multiple manufacturing methods such as 3D printing, CNC machining, vacuum casting, and rapid injection molding.
Each method has different:
- Cost
- Lead time
- Material performance
- Scalability
Choosing the wrong method can lead to delays, redesign, and wasted cost.
In this guide, we’ll help you:
- Compare different prototyping methods
- Understand cost and lead time
- Choose the right solution for your project
Types of Rapid Prototyping Processes
1. 3D Printing
- Fastest
- Low cost
- Poor strength
2. CNC Machining
- High precision
- Good for metal & plastic
- Higher cost
3. Vacuum Casting
- Good for small batch
- Silicone molds
- Medium durability
4. Rapid Injection Molding
- Real production materials
- High accuracy
- Suitable for 100–10,000 units
Rapid injection molding bridges prototype and mass production
Rapid Prototyping Methods Comparison
| Method | Speed | Cost | Strength | Best For |
|---|---|---|---|---|
| 3D Printing | ★★★★★ | ★ | ★ | Concept |
| CNC | ★★★ | ★★★ | ★★★★ | Precision parts |
| Vacuum Casting | ★★★★ | ★★ | ★★ | Small batch |
| Injection Prototype | ★★ | ★★★ | ★★★★★ | Functional testing |
How Much Does Rapid Prototyping Cost?
Typical pricing:
- 3D printing: $10 – $100
- CNC: $50 – $500
- Vacuum casting: $100 – $1000
- Rapid injection molding:
- Tooling: $500 – $3000
- Part cost: $0.5 – $5
Rapid tooling can reduce cost by up to 60% vs traditional molds
Lead Time Comparison
- 3D printing: 1–3 days
- CNC: 3–7 days
- Vacuum casting: 5–10 days
- Rapid injection molding: 5–15 days
When Should You Use Rapid Injection Molding?
Choose this if:
- You need real production materials (ABS, PC, Nylon)
- You plan to move to mass production
- You need functional testing
Avoid if:
- Only visual prototype needed
- Quantity < 50
Applications
- Consumer electronics
- Automotive parts
- Medical devices
- Industrial components
From Prototype to Mass Production: What You Must Consider
Before choosing a supplier, confirm:
- Can prototype mold design scale to production?
- Are production materials available?
- What is mold life (shots)?
- Can design be modified easily?
Poor planning here can increase cost dramatically
