Creating a Metal Prototype: Which Method Is Best for Me?

Last Updated on March 16, 2024 by assistant

Metal prototyping plays a crucial role in the development of various products, from automotive parts to medical devices. While the cost of metal prototyping can be higher compared to plastic prototyping, there are situations where metal prototypes are essential. In this article, we will delve into different methods of creating metal prototypes and highlight their key features.

Understanding Metal Prototypes

A metal prototype is a tangible and functional representation of a product or part that is created using metal materials. It allows designers, engineers, and manufacturers to test and evaluate the form, fit, and function of a product before moving into full-scale production. Metal prototypes are particularly valuable when properties such as strength, durability, heat resistance, and weight are critical to the final product.

Now, let’s explore some of the prominent techniques for creating metal prototypes:

1. CNC Machining
Computer Numerical Control (CNC) machining stands out as a versatile and highly accurate method for metal prototyping. It involves using computer-controlled machines to precisely shape and cut metal into the desired form. Our online CNC machining services supports various grades of metals, making it suitable for producing functional metal prototypes.


One of the advantages of CNC machining is its cost-effectiveness compared to metal 3D printing. Moreover, it offers faster lead times since it doesn’t involve tooling manufacturing, allowing you to obtain your prototype within a matter of days.

2. Metal 3D Printing
Metal 3D printing, also known as additive manufacturing, has gained prominence for creating lightweight and complex metal prototypes. This technique enables the production of intricate designs and the fabrication of one-off parts in a single assembly, eliminating the need for multi-component fabrication.


With metal 3D printing, materials like aluminum, steel, Cobalt Chrome, Titanium, and Inconel can be utilized, offering the ability to emulate the mechanical properties of the final product. However, it’s important to note that the cost of metal printing is still relatively higher compared to plastic 3D printing.

3. Sheet Metal Prototyping
For certain applications, sheet metal prototyping presents an effective option. This method involves shaping thin sheets of metal through cutting, bending, forming, and laser cutting to create the desired prototype. Sheet metal fabrication is often used in applications such as enclosures.


Sheet metal prototyping is cost-effective and efficient, providing options for materials like mild steel, CRS, and spring steel. However, it’s crucial to adhere to specific thickness requirements, typically ranging from 0.006 inches to 0.25 inches.

Choosing the Right Technique

Selecting the appropriate metal prototyping technique depends on the specific requirements and priorities of your project. If design freedom and complexity are crucial, metal 3D printing can be a suitable choice. On the other hand, if you prioritize quick turnaround times and high precision, CNC machining is a reliable option.


Metal prototypes play a vital role in the product development process, enabling testing and refinement before moving into mass production. By understanding different metal prototyping techniques like CNC machining, metal 3D printing, and sheet metal prototyping, you can choose the most appropriate method based on your project’s needs. Remember, it’s always beneficial to consult with experts who can guide you in selecting the optimal metal prototyping process for your specific requirements.
