Well, this is a whole new can or worms.
Many people will have seen that the 3D Printing community has thrown it's brains and brawn to the task of addressing shortages of very critical equipment. One of the most pressing demands are ventilators and respirators.
These come in different types and there is a whole lot to the techniques used in medicine for patients needing assisted respiration.

There is a link to a video, from a resource called, that starts explaining what the parameters of assisted respiration are.
Here is a different video going into greater detail of the design of a ventilators and why it is important to take in consideration some crucial criteria that will avoid doing more ham than good.

Please use this forum to add further information on this topic.

Another link to an open source ventilator:

MTU Open Source Hardware Enterprise will be documenting, building and testing open source ventilators. If you want to help please do.

We donated resins and knowhow to fabricate ventilator parts

During the past week we have been testing, in a joint project with the Hospital of Sagunto and a 3D printing company, our zero VOC, low citotoxicity resins to print connector pieces for the innovative and widely adopted Isinnova ventilator design, based on snorkeling mask.

We wanted to use this resin, based on our Clarity Hard product as it has zero VOC, so no volatile monomers or solvents that would enter the air-stream and could further irritate the lung tissue, as well as being very biocompatible. This was our first choice among other candidates, as we understood that these pieces are consumables, meaning that they are swapped for every new patient that is connected, as you want to avoid cross-contamination. The pieces could also be sterilized in an UV or hot air sterilizer, if the need arises, but if they can be printed quickly and cheaply enough, it is much safer to substitute them with a new one.

The printers that are being used are Wanahoo and Asiga printers, so rather on the low power side, which needed some adjustment and testing to make the resin conversion high enough to reach the desired properties. On top of our expertise we donated the resin to start churning out these connectors as well as other more common connectors for Oxygen and air tubing and they are now being distributed in hospitals and emergency units.

We want to transmit our support and appreciation to all medical personnel through the world that are assisting the patients in this crisis. Their dedication is always on our mind!
