Rapid prototyping refers to any method used to quickly build a physical part (or even an entire assembly) from a 3D design. It allows engineers and designers to see and test their designs in the real world much faster. One of the key technologies behind rapid prototyping is 3D printing, and a particularly useful type is called fused deposition modeling or FDM — a versatile 3D printing technology that can create parts with complex geometries. FDM rapid prototyping allows you to turn your ideas into actual concepts cost-effectively and speed up your project’s turnaround times.

How FDM 3D printing works

Fused deposition modeling crafts a part by melting an extruded thermoplastic filament. The printer nozzle deposits that filament one layer at a time in the build area. This printing method makes it possible to realize complex features with support material for overhanging features.

Supporting product designers

Engineers and designers who need quick and affordable models or prototypes can benefit from FDM rapid prototyping. This 3D printing technology can support a wide range of thermoplastics, such as PLA and ABS, and various blends. Advanced printers can also support engineering thermoplastics and composites.

While FDM 3D printing might not produce the same level of fine detail as some other 3D printing methods, it's still a very capable technique. Many rapid prototyping companies offer finishing services such as mechanical or chemical polishing if you require a smoother and more polished look. Another helpful technique is the use of soluble support structures, which can help overcome some of the challenges sometimes encountered with FDM printing.

Applications

FDM rapid prototyping can be used to create low-volume prototype parts from a range of materials, including PC, ABS, nylon, and Ultem, allowing designers and engineers to realize custom designs for functional components as well as housings and enclosures. Because of its accuracy, FDM 3D printing is not only suitable for prototyping but also for low-volume end-use production and the fabrication of small, detailed parts.

Design tips

When considering FDM rapid prototyping, take the time to choose a reliable manufacturing partner who can give tailored design tips according to your project. For example, experienced manufacturers often suggest designing holes slightly larger than needed because FDM printing can cause them to shrink by about 2% to 4%. They may also recommend incorporating inserts for any holes that require threading.
