Biomedical device fabrication

Hello everyone! I am Federico,
I am looking for useful information regarding the fabrication technique and consequently the most suitable materials for manufacturing a device for use in biomedical research. Specifically, the device is about 15x3x3 cm in size and has many empty spaces and channels inside. I am interested in identifying the fabrication method that will allow me to ensure a good accuracy of the geometry, possibly without spending too much money (no exaggeratedly high accuracy required, no too small components). In your opinion, could HP Multi Jet Fusion be a good solution? And possibly, can PP be a good material? I know it is often used for biomedical applications due to its hydrophobic and chemical inert capabilities; however, the part will need to be in a 37°C and high humidity environment for a long time.
Thank you very much to anyone who can help me!
Federico

Hi Frederico,

nice to meet you and thank you for your question.

For a humid environment it would help to have a closed surface. In MJF we have a postprocessing, called vapour smoothing which seals the surface completely.

It is not so successful with PP. But PA12 in MJF could be a good solution here.

If necessary we could you also a printing in ISO 13485. This would be in SLS and PA12.

Hope this answers your questions.

best regards

      Hello, Federico,

      How fine are the features/channels that you are referring to? Maybe you could also share a screenshot with some of the features – just to take a look and assess whether MJF/SLS can be a good solution here?
