- Hybrid Approaches: Some companies use hybrid manufacturing techniques combining 3D printing with traditional methods. For instance, 3D printed inserts can be integrated into CNC-machined tooling to reduce machining time and cost while leveraging the benefits of both technologies.
- Conformal Cooling: In injection molding, conformal cooling channels can be incorporated into 3D printed molds. These channels follow the shape of the part, optimizing cooling and reducing cycle times, which improves productivity and part quality.
- Tooling Inserts: 3D printing enables the creation of inserts for composite tooling. These inserts can be used to reinforce tooling made from other materials, improving durability and extending tool life.

Materials for 3D Printed Tooling:
- High-Temperature Materials: Certain thermoplastics and resins are capable of withstanding high temperatures, making them suitable for tooling applications where heat resistance is crucial.
- Metal 3D Printing: Techniques like Direct Metal Laser Sintering (DMLS) or Selective Laser Melting (SLM) allow for the production of metal tooling inserts. Metals such as stainless steel, tool steel, or even titanium can be used for robust tooling applications.
- Composite Materials: For specialized applications, composite materials reinforced with fibers (such as carbon fiber or glass fiber) can be used. These materials combine strength and lightness, ideal for certain tooling needs.
Industry-Specific Applications:
- Healthcare: Rapid tooling is utilized for manufacturing custom medical devices, prosthetics, and patient-specific surgical tools. The ability to quickly iterate designs and produce personalized products is critical in this sector.
- Automotive: In automotive manufacturing, 3D printed jigs and fixtures assist in assembly processes, while tooling for prototyping and low-volume production parts reduces lead times and costs.
- Consumer Electronics: For small-scale production runs and rapid prototyping of electronic enclosures and components, 3D printed tooling is beneficial in achieving fast turnaround times and customization.
