Definition and advantages
3D printing is an additive manufacturing technology that creates objects layer by layer from a digital 3D model. This makes it an ideal technology for the production of prototypes, as it allows complex geometries and structures to be created that are not possible with traditional methods.
What is additive manufacturing technology used for?
Additive manufacturing technology is used in construction to produce prototypes of products and components. This allows designers to test and improve their designs before they start mass production. 3D printed prototypes can also be used to obtain customer feedback and ensure that products meet user requirements. In the past, expensive tools/moulds had to be produced in order to test or optimize a product. This took a lot of time.
Advantages of 3D printing
Some of the benefits of using 3D printing for prototyping are:
- Faster and more cost-effective than traditional methods
- Enables the production of complex geometries and structures
- Enables the rapid iterative development of designs
- Enables easy customization of designs based on customer feedback
- Enables the production of prototypes of products that are not possible with traditional methods
The use of 3D printing in construction is still relatively new, but the potential of this technology is enormous. 3D printing will change the way we develop products and components and it will help bring new and innovative products to the market. By using 3D printing, it is possible for designers to create their designs faster, more cost-effectively and with greater flexibility.
The production of prototypes using the 3D printing process can significantly reduce material and energy costs. In conventional prototyping, CNC milling is used to produce the model from a large block of material, in which material is removed and shaped accordingly. This process wastes a lot of raw material, whereas the 3D printing process only uses the material that is “really” needed. In addition, no special molds or tools need to be produced.
Overall, this additive manufacturing technology has the potential to improve sustainability in product development, for example through the use of recycled materials. By using 3D printing, companies can make their products more sustainable and contribute to environmental protection.
Advantages for the design
Advantages of 3D printing in construction summarized once again:
- Faster development: 3D printing enables designers to create prototypes faster than with traditional methods. This can speed up the development process and lead to new and innovative products.
- Reduced costs: 3D printing can reduce the cost of producing prototypes. This is because 3D printing does not require tools or molds, which can be expensive with traditional methods.
- Increased flexibility: 3D printing enables designers to create prototypes with complex geometries and structures that are not possible with traditional methods. This can lead to new and innovative products that better meet user requirements.
- Improved quality: 3D printing can improve the quality of prototypes. This is because 3D printing is a precise and reproducible technology.

Challenges of 3D printing in mechanical engineering
- The cost of 3D printing has fallen. Further progress needs to be made here to make the technology economically viable.
- When using 3D printers for mass production, the process must be scalable in order to meet the requirements. (increasing production capacity, overcoming bottlenecks)
- Ensuring the consistently high quality of printed products is essential. The development of standards and procedures for quality control is therefore necessary.
- The range of materials available for 3D printing in mechanical engineering needs to be expanded in order to better meet the requirements.
The future of 3D printing in mechanical engineering
The use of additive manufacturing technologies in construction and mechanical engineering will continue to increase in the coming years. This is because 3D printing offers a number of advantages that can improve the development and manufacture of products. 3D printing will change the way we develop and manufacture products. It will help to bring new and innovative products to the market that better meet the needs of users.
