Achtung: Masken und Beatmungsgeräte aus dem 3D-Drucker

Caution: Face masks and ventilators out of 3D printers 

With the cur­rent pan­dem­ic and cri­sis, the 3D print­ing com­mu­ni­ty has made its con­tri­bu­tion. Man­u­fac­tur­ers around the world devel­oped masks and ven­ti­la­tors to alle­vi­ate the glob­al short­age. 

Caution: Free 3D files for printing

Web­sites like Yeg­gi or Thin­gi­verse cur­rent­ly offer many free 3D files of masks and res­pi­ra­tors for print­ing. 

Websites like Yeggi or Thingiverse currently offer many free 3D files of masks and respirators for printing. 

Free 3D masks for down­load online.

We encour­age every­one to seek med­ical advice when it comes to health. Masks from pri­vate pro­duc­tion are like­ly to help, but there is no hard evi­dence with regards to 3D print­ing. Almost all devices and files are nei­ther approved nor val­i­dat­ed by experts. Nev­er­the­less, there is no rea­son not to exper­i­ment with your own 3D print­er. 

At this point, we want to show 2 med­ical­ly approved and promis­ing med­ical 3D print­ing projects. 

Expert approved ventilator in Spain

The first med­ical­ly approved 3D pres­sure ven­ti­la­tor was devel­oped and approved by med­ical experts in Spain. It is an emer­gency device that can help patients breathe for a lim­it­ed time. The local alliance aims to indus­tri­al­ize pro­duc­tion to man­u­fac­ture hun­dreds devices per day.

Manel Bal­cells, Health Com­mis­sion­er at Lei­tat Tech­nol­o­gy Cen­tre:
“This is an emer­gency ven­ti­la­tor designed using 3D tech­nolo­gies and incor­po­rat­ing oth­er parts avail­able on the mar­ket. Assem­bly is very fast, so we can pro­duce about 100 units per day, and I hope there will be many more in the com­ing days”.

Face mask from Copper 3D

In addi­tion, man­u­fac­tur­ers also devel­op more inno­v­a­tive face masks out of 3D print­ers. Basi­cal­ly, the glob­al stock of face masks col­lapsed dur­ing March. In most coun­tries this is a basic require­ment for the gen­er­al pop­u­la­tion. While these masks are effec­tive they also have some prob­lems  such as poor lat­er­al fit, short life span (about 8 hours) and anoth­er, even more seri­ous prob­lem. 

Virus­es, espe­cial­ly SARS-Cov­‑2 (COVID-19), can live up to 72 hours on var­i­ous sur­faces. This is a prob­lem because when we use a con­ven­tion­al mask at the end of the day we have a high viral load trapped with­in mil­lime­tres of the nose and mouth. Cop­per 3D’s approach is there­fore to use active (antimi­cro­bial) mate­ri­als to address this prob­lem.

Summary

Google’s search for 3D print­ing explod­ed in recent weeks. Appar­ent­ly, fight­ing the pan­dem­ic with 3D print­ing increased pub­lic inter­est for the tech­nol­o­gy.

Addi­tive manufacturing/3D print­er cur­rent­ly demon­strate their ben­e­fits in a decen­tralised pro­duc­tion. This will be a big issue in the com­ing months, and def­i­nite­ly a key asset for 3D print­ings future devel­op­ment.
