Rapid Prototyping with 3D Printing

Traditional manufacturing methods often force companies into lengthy and expensive prototype cycles. Tooling, machining, outsourcing, and manual fabrication can add weeks or months to development timelines. Additive manufacturing removes many of these bottlenecks by enabling engineers to move directly from a CAD file to a physical part, creating a more agile product development process.

Rapid prototyping typically follows an iterative workflow:

1. Defining requirements
2. Creating a 3D design
3. Preparing and printing the model
4. Post-processing the part
5. Testing its performance before making refinements
6. Iterating and refining the design

While the process may be repeated multiple times, each iteration helps identify issues earlier, optimize designs, improve manufacturability, and reduce downstream rework—ultimately accelerating development and helping bring higher-quality products to market faster.

Before additive manufacturing, product development was constrained by tooling costs, manufacturing limitations, and long lead times. A single injection mold could cost tens or even hundreds of thousands of dollars. Machined prototypes often required highly skilled labor and extensive programming time. Every design change introduced additional cost and delay. 

While traditional manufacturing remains essential for high-volume production, rapid prototyping offers several critical advantages during development and low-volume production phases. 

Over the last four decades, 3D Systems has developed one of the industry’s broadest additive manufacturing portfolios, enabling companies to select technologies optimized for specific applications, materials, surface finishes, precision requirements, and throughput needs.
