Case Study

 

3D printing is becoming more and more popular in the production of medical devices. 

 

Emtel 3D printed the prototype of a patient monitor case in 1:1 scale.  The project was developed to reduce the weight and increase the stiffness of the element.

  
 

Prototyping

3D printing is becoming more and more popular in the production of medical devices.

The Emtel company, a Polish manufacturer of electronic medical equipment, has implemented 3D printing technology and uses it in the process of prototyping.

The competitiveness of medical device manufacturers is determined by the continuous improvement of devices, connected with building and testing prototypes. An optimal solution for entrepreneurs who want to avoid high costs and downtime at work and to easily prepare new versions of their devices may be the introduction of 3D printing technology.

Additive manufacturing technology allows you to shorten the time needed by constructors and engineers to create and test products. Currently, 3D printing has ceased to be seen only as a tool used only for prototyping, evolving towards the printing of final products. Compared to traditional methods, it can positively affect time and cost of production. This is due to the improvement of the quality, reliability and range of available materials in the cheapest FDM / FFF printing technology

 3D technology helps the company to build models of cardiac monitor cases. Earlier, Emtel commissioned them to be prepared for an external company, which raised costs and extended the duration of the entire process. Thanks to 3D printing, the company achieved a tenfold reduction in costs and shortening the production of housing
from 30 to 5 days.

Goals

Creating a prototype to verify the design at lower costs

Usually, the knuckles are being made of aluminum by milling. The introduction of significant changes in the geometry of the part makes it impossible for such a complex shape to be subjected to conventional machining. In order to verify the project, without big financial investment, FDM technology was chosen.

The 3D printed steering knuckle helped to verify the project’s assumptions before forming the model itself and avoid costly improvements in other technology (printing in SLS technology reached up to 20,000 €).

Reducing the time of prototyping

Due to the FSAE race in Michigan, AGH Racing had to make a prototype of the new model of steering knuckle in a very short time. 3D printing in FDM technology allowed to receive a prototype much faster. The use of soluble ESM-10 solution as a support material allowed for efficient post-processing of the model. SLS prototyping would take too long.

Thanks to the 3DGence INDUSTRY F340 a prototype was 3D printed in less than 2 days. This time reduction allowed students to present new details to the judges.
