Custom design is the process of creating a unique product or part that is specifically designed to meet a customer's requirements. This involves designing, prototyping, and manufacturing the product to precise specifications. The process of custom fabrication can involve various techniques and materials, including CNC machining, 3D printing, laser cutting, and welding, among others.

Custom design is often used when a standard off-the-shelf product or part is not suitable for a specific application. By customizing the design, the product can be optimized to meet the specific needs of the customer, resulting in a better-performing and more efficient product.

Custom design requires close collaboration between the customer and the fabricator to ensure that the final product meets all requirements and is of high quality.

One of the key benefits of custom design is the ability to create a product that precisely meets the customer's needs. This can result in improved efficiency, performance, and cost-effectiveness. Additionally, custom fabrication allows for greater flexibility and innovation in design, as it is not constrained by the limitations of off-the-shelf products.
