Strategies to reduce the cost of the 3D printing process

The 3D printing technology offers numerous advantages such as production speed, a wide variety of materials, or the creation of complex parts. However, one of the main concerns when choosing this method of part and prototype manufacturing is its cost.  

Reducing the cost of the additive manufacturing process is possible through design optimization, selection of appropriate manufacturing options, and finish and materials used. 

In this article, we highlight some useful tips or strategies to reduce the cost of 3D printing.  

Cost reduction in the product design phase

There are several ways to reduce costs through product design.  

First, a good way to use less material and, therefore, reduce the cost is by hollowing out a 3D model. In this way, material is removed from the interior of the part, and in addition to reducing the cost, a lighter part is achieved.  

On the other hand, it is essential to take into account the size of the 3D printed part. If the size of your prototype is not important, as it is simply a visual prototype, a good way to reduce the cost would be to reduce the scale of the model.  

Reduce costs by selecting the appropriate materials

The best way to reduce material costs is by choosing the right material according to the needs of each project. If the printed part is just a visual model, it may not be necessary to print it in a high-performance material, which will always have a higher price.  

Likewise, choosing the right process for each project can also help reduce costs. Technologies like FDM and MJF are much more economical than others like SLS. Therefore, once again, it is necessary to consider whether the use of 3D printing aims to create prototypes or visual models or, on the contrary, requires high-end printing. 

Finally, it is necessary to consider the production volume. 3D printing is the best option for short runs of parts or for individual units. On the other hand, for larger batches, the best option would be to choose other technologies such as CNC machining.  

Cost reduction in the post-processing or finishing phase of the part

Finishing can also increase the price of 3D printing. On one hand, finishes like dyeing are a more economical way to color parts compared to painting. However, painting provides a more durable color and higher quality.  

In short, the choice of one option or another will always depend on the needs and requirements of each project, but you must always consider the strategies that allow you to optimize the process and save on the costs involved in 3D printing technology.
