How To Choose: CNC Machining Vs. 3D Printing For Your Prototype?
Technological choice is very important for setting the parameters for controlling the rapid prototyping cost. Organizations tend to take wrong decisions and have to make judgments based on four important criteria, otherwise, all efforts during the whole development process go to vain.
What are the four key dimensions that define the technology path?
1. Material Performance Requirements: In case the prototype must resist high temperatures and high pressures or mechanical forces for example engine components in the case of rapid prototyping in automobile industry, the prototype CNC machining process must be selected that can utilize the same metals used in mass production.
2. Geometric Complexity: When there are internal fluid flow passages or lattices, for example in medical devices, 3D printing offers a better alternative for manufacturing these parts.
3. Precision and Surface Requirements: When working with prototypes and the required tolerance is beyond ±0.05mm, exact fitting for the surface is required. Here, CNC machining is more suitable.
4. Quantity & Cost: For production of complex parts and for a production volume ranging from single units up to 10 units, 3D printing is cost-effective, while for prototyping and a production volume ranging from 10 units to 50 units, CNC machining is more cost-effective.
| Process Type | Dimensional Tolerance | Surface Roughness Ra | Material Tensile Strength (MPa) | Heat Resistance Temperature (°C) | Single Piece Processing Time (h) | Suitable Batch Size | Material Utilization Rate (%) |
| Rapid Prototyping CNC Machining (6061-T6) | ±0.025mm | 0.8-1.6μm | 310 | 230 | 1.5-4 | 10-50 pieces | 75-85 |
| SLA 3D Printing (Medical Resin) | ±0.1mm | 1.6-3.2μm | 55-70 | 80-120 | 0.5-2 | 1-20 pieces | 90-95 |
| SLM Metal 3D Printing (Ti-6Al-4V) | ±0.05mm | 3.2-6.3μm | 860 | 400 | 4-8 | 1-10 pieces | 85-90 |
| SLS 3D Printing (PA12 + Glass Fiber) | ±0.2mm | 6.3-12.5μm | 65-80 | 150 | 1-3 | 20-100 pieces | 95-98 |
| Prototype CNC machining (304 stainless steel) | ±0.03mm | 1.0-2.0μm | 515 | 870 | 2-6 | 5-30 pieces | 70-80 |
This table clarifies process boundaries from performance and efficiency perspectives, providing a quantitative basis for precision rapid prototyping selection.
Why does high load functional testing usually rely on CNC machining prototypes?
Prototype CNC machining uses mass-production-grade materials with mechanical properties consistent with the finished product, irreplaceable by plastic 3D printed parts, and core choices for high-load testing.
How To Tackle The Prototype Challenges Of Highly Regulated Industries? Taking Medical Device Rapid Prototyping As An Example
Compliance is the most important and critical element in medical device rapid prototyping, and is directly related to whether registration will be passed or fail. JS Precision has rich experience in this area, and can precisely avoid wasting of upfront investment.
What unique requirements beyond technology do medical device prototypes face?
1. Biocompatibility Certification: Prototype materials shall pass ISO 10993-5 cytotoxicity testing and USP Class VI certification to avoid adverse reactions once the device comes into contact with the human body.
2. Sterilization Validation: The prototype should support such methods for sterilization as gamma rays and EO, its performance shouldn't change after sterilization.
3. Registration Support: The prototype system should be useful for type testing and supply full traceability reports regarding the material used, and test data, as part of the registration submission documents.
What qualifications and skills are to be verified when working with a medical prototypes service supplier?
- ISO 13485 Quality System Certificate: This is the basic certification for the prototype services for medical devices. It ensures that the production process is compliant with the medical industry standards.
- Cleanroom Environment: Prototyping must be performed at a Class 8 or higher cleanroom level to prevent any contamination which could adversely affect the system’s biocompatibility.
- Traceable Material Supply Chain: Provide capabilities for reporting batches and issuing certification certificates for materials.
- Registration-related Experience: Knowledge about regulations such as the "Guiding Principles for Medical Device Software Registration Review," and the capability to provide support in formulating UDI (Unique Device Identifier) along with information needed for registration.
Practical Analysis: How to Accelerate Product Registration and Market Launch for Orthopedic Guide Plate Prototypes?

What Is The Key To The Success Of Industrial Prototyping Development? From Project Management To Cost Control
The important point about successful industrial prototyping is related to management. The majority of organizations disregard the cost not included. JS Precision uses a closed management system, thus enhancing acceleration.
How to systematically manage an industrial prototyping project to achieve success?
1. Define requirements clearly: Engage with the client to prepare a "Requirements Definition Document" in the initial stages to clearly define the prototype testing requirements and acceptance criteria (e.g., critical dimension CPK > 1.33).
2. Pre-project DFM Meeting: This is a meeting that takes place before the start of a project with the aim of improving the design so that the manufacturing process becomes easier.
3. Transparent communication: Create a project team to coordinate information about the progress of production and quality checks in real-time.
4. Closed-loop verification: Include a 3D scanning inspection after the delivery of the prototype, where the comparison of the deviation level of the design model and the prototype will form the basis of the next iterations.
What constitutes rapid prototyping cost? How to optimize it?
Rapid prototyping cost includes programming fee, material fee, machine hour fee, and a 30% post-processing fee. This can be managed either through the use of DFM or through material substitution.
- Design Optimization: Optimize designs using DFM, removing hard-to-manufacturing features such as deep cavities or complex curved geometries,
- Material Substitution: Identify the usage of lower-cost materials that have similar properties.
- Batch Integration: Combine several small parts into an assembly to be processed, thus reducing the setup time.
- Supply Chain Advantage: Leverage the discounted prices for bulk purchases offered by JS Precision.
JS Precision combines process combination with DFM optimization to accurately balance rapid prototyping cost and performance, avoiding ineffective investment.
