Industrial 3D printing optimizes tool and mold making

For many companies, manufacturing injection molding or shaping dies is one of the most expensive, time-consuming steps in the production process. Despite ultra-precise tooling machines, established ablative or shaping processes often reach their limits when it comes to complex geometries. Additive manufacturing offers new opportunities to optimize tool making processes while increasing tool productivity significantly.

Conventional tool making uses ablative and shaping production process, such as milling, turning or drilling. These are associated with various process-related restrictions in implementation, made clear by the following practical example: Hot stamping or injection molding requires tools with integrated cooling channels. A coolant is passed through these channels to help quickly and evenly dissipate heat. Until now, these types of channels were simply drilled into the tool, something that could physically only be done in a straight line. With more demanding geometries, this makes it virtually impossible to place cooling channels evenly and near the surface of the workpiece.

Improved functionality thanks to 3D printing

Since complex shapes inside the workpiece cannot be implemented adequately using ablative or shaping methods, potentials for improvement are often left untapped. Here is where one of the greatest advantages of additive manufacturing comes into play: 3D printing creates objects made of shapeless base materials using CAD data. The layered structure does not require additional tools and enables the integration of complicated geometries based fully on the functionality and design of the component.

Optimized tool geometry improves heat dissipation, cutting cycle times for injection molding by one-third on average. Thanks to less warping, the quality of the injection-molded parts is increased significantly.

Tools from industrial 3D printing

  • enable even heat dissipation
  • reduce cycle times
  • increase quality of injection-molded parts

Industrial 3D printing on the PROTIQ Marketplace

All you need to produce your 3D object is a printable CAD model of your workpiece. On the PROTIQ Marketplace, production can begin as soon as your order is received. You receive your 3D-printed part for tool making just days after placing your order.

To ensure the necessary surface quality for injection-molding tools, all external surfaces of your 3D model should have an offset of 0.7 to 1 mm. Following production, all components are conventionally finished and trimmed to size. Industrial 3D printing not only creates new objects, but in some cases can also repair damaged tools.

3D printing – advantages for tool making

  • Save money for the long term: Shorter cycle times and improved part quality lower the unit price for series products
  • Discover new possibilities: Design-based construction increases innovative potential
  • Fast production: Production of your 3D workpiece begins as soon as your order is received

How does 3D printing differ from conventional tool shops?

Im Gegensatz zur klassischen Fertigung, bei der Werkzeuge durch Fräsen, Bohren oder Gießen entstehen, wird beim 3D-Druck das Bauteil schichtweise direkt aus digitalen Daten aufgebaut. Dadurch entfallen viele Einschränkungen in der Geometrie und es sind komplexe, funktionsintegrierte Formen möglich – etwa mit innenliegenden Kühlkanälen.

What are the advantages of 3D printing for injection molds?

The option of integrating cooling channels close to the contour means that heat is dissipated more efficiently. This leads to shorter cycle times, better component quality and a longer tool life. In addition, changes to the design can be implemented quickly without having to produce new tools.

What geometries are possible with 3D printing that cannot be realized with conventional processes?

Additive manufacturing enables the production of free-form surfaces, internal structures and complex channel guides that would be very difficult or impossible to realize using conventional methods. This opens up new possibilities in tool design and function integration.

What post-processing is possible or necessary?

Depending on the application, mechanical finishing may be required, for example to improve the surface quality or to maintain tight tolerances. PROTIQ offers corresponding options such as milling, grinding or polishing.
