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. 

  
 

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

Cost reduction at the stage of creating models and prototypes

The production cost of one patient monitor case made by external companies is about 500 EUR. Additionally, at the stage of forming the prototype, it is necessary to produce around 2 or 3 versions of the
same model.

Reducing production costs of
models up to 90%. The cost of asingle 3D print is around 50 EUR.

Speed-up of project processing at the stage of models verification

The production process of models and prototypes made by external enterprises takes minimum one month. Ownership of a 3D printer allows quickly make a designed model in 1:1 scale with satisfactory accuracy.

The prototype of the patient monitor was received in 5 days which reduced expectation time up to 25 days.

Project verification through the installation of target components in the 3D printed casing

During the production of the case to patient monitor FX3000P, the expected precision was not worse than 0.2mm, especially in the mounting brackets. 

3D printouts allowed to verify all critical dimensions of the project, it enabled to implement proper corrections.

Approvement of documentation to injection mold production

Fast prototyping of new patient monitor model through precise verification of project assumptions, ergonomy, installation and validation of dimensions was only able due to the use of a 3D printer.

The final details obtained with the use of injection technology did not require any corrections.
