Stop the Coronavirus Spread with 3D-Printing


Did you know, one of the most germ-infected places in homes, hospitals, care homes, and factories, is our everyday door handles? And unless you are going around disinfecting them every time someone touches them – which is entirely unfeasible, even in a home environment – germs will build up.

To fight the spread of Coronavirus, and help build a better, healthier world, 3D printing company Materialise has shared free design files for the full range of its 3D print hands-free door openers.

'Cylindrical, Wide' design for doors of an above-average weight, including fireproof doors with hydraulic pumps 

By using covered arms instead of bare hands to open doors, we can work together to avoid passing on COVID-19.

If you have your own 3D printer, head over to Materialise now and start printing your own protective hands-free door openers. If you don’t have a 3D printer, you can order the size of your choice on i.materialise now!

Files are available in STL format, so DesignSpark Mechanical users can download, adjust and print from home.

You can even download a free sticker design to attach to your hands-free door opener!

So, thank you Materialise, and in your words: “let's work together to stop the spread!”

I like the idea, and downloaded them. They can be of use even apart from virus concerns, sometimes increasing accessibility for people who may have impaired use of their hands.
Also, while I have and utilize 3D printers myself, I keep in mind that sometimes other construction methods are faster or stronger. Don't forget woodworking, metalworking, or even string/twine and rod or coat hanger. Or a combination of 3D printing and other fabrication methods and materials. 3D printing can be great when you need to adapt to non-flat surfaces - although it may take significant skills (along with a 3D cad program like DesignSpark Mechanical) and some expertise to design the "match" to more than the simplest curved surfaces. An example of using materials and techniques to their best advantage might be using a relatively small 3D-printed adapter to go between a wooden paddle and the irregular-shaped handle you are trying to attach it to, and a piece of rubber between the 3D-printed part and the handle to help better match the 3D-printed surface to the handle, reducing the modeling precision needing in defining the mate to the handle surface.

Great to see how 3D printing and the maker scene can help in this situation!
But please also try to get informed well and try to avoid dubious sources of information these days. The actual state of knowledge about the infection path of COVID-19 is the following:
There is little evidence that the virus is spread by contact of objects. The main infection path is an airborne infection by breath droplets. Although the virus survives on surfaces from 2 hours up to 9 days, it seems to lose its pathogenicity very quick.
Nevertheless, not touching public used surfaces with your fingers make sense these days. But remember the main method of prevention should always be to often wash your hands carefully for at least 30 seconds after touching public surfaces and not to touch your face before you have washed your hand. And even more important and the only practical measure to reduce airborne infection is to keep at least 1.5 meter distance to other people.
