To Whom it may concern,

In the CORVID-19 pandemic, Cracow University of Technology (CUT) try to help all medical staff fighting for our live. Group of CUT scientists print protection equipment for them using 3D printers. Face shield - A4 binding sheet - easy punching can be easily printed by users of 3D printers all around the world, to help in protection against COVID-19.

A proposed face shield (3D printed), developed originally by Prusa 3D printing company can be printed by anyone having a 3D printer. During last days many modification have been made in the original project by researchers from the whole world e.g. proposed by scientist from Wroclaw University of Science and Technology. Also at Cracow University of Technology some modifications have been made to speed up the process of the printing these models, because as we know – now every second counts… More information about the projects modified by Marcin Tekieli PhD and Damian Brewczyński MSc can be found here. Both projects are adapted to mount covers made on the basis of slide film in A4 format. Both face shield types have been already tested by the medical stuff in many hospitals here in Cracow. For all those who would like to print such a helmet on their 3D printers, we provide the STL format model, available in the attached file.

More information about CUT initiative (in Polish) can be found here.
STL file of the face shield model can be also found here.

Please pass this instruction to interested people, who can print protecting face shields.

Yours sincerely,
IB2MaC 2020 Organizing Committee

Dear Participants of the 17th IB2MaC conference,

Due to the situation related to the spread of COVID-19 in the world, we would like to inform you that the Conference has not been cancelled and it is not planned to postpone it to another date, because no one knows when COVID-19 will expire.

We decided to organize an online conference as close as possible to regular ones and publish articles by the Balkema publisher . Participants want to publish their work already done in this difficult time (only a few articles have been withdrawn), so we will not lose their hard work (especially of young scientists). The future is now still unknown. We are afraid that some universities may have problems with funding for conferences next year.

After calculating of the conference budget, the Organizing Committee decided about partial reimbursement for online participation. All participants who overpaid the reduced fee will receive individual reimbursement forms with calculated refund.

Participation in the conference online without paper publication is also possible, after paying the online participation fee of 220 EUR.

A number of participants declared only paper publication in Balkema, thus we have only a few reserved spaces in online conference sessions for additional presentations. For those participants who want to participate online in the conference and present their work without publication, the online presentation fee is 300 EUR.

Qualification for presentation without publication will be done basing on the sent one page abstract. Please express your interest by sending information to the Organizing Committee (
The amount of reserved space in conference sessions for additional presentations is limited.

Last week we finished the editing process and sent submitted articles to Balkema. Finally, we sent 133 articles: 4 keynote, 7 semi-keynote and 122 regular. Now we are waiting for the ready e-book. A list of the conference articles with authors and titles can be found on the conference website. Access by means of a token to full texts should be available to participants before the conference.

We have started the next organizational stage of the conference. The first draft of the online conference program is presented on the conference website. We organize two parallel sessions blocks over 3 days with two special sessions and invited keynote and semi-keynote lectures. In addition, other conference activities will be available online: expert panel, Royal Castle Wawel tour, technical tour, concert, photo gallery and competitions (Best Paper Award and Best Photo Award). Accompanying events such as meetings and workshops are also planned. Detailed information will soon be available on the conference website.

We hired a professional supplier of online meetings to organize online conference sessions as close as possible to the traditional ones, based on a special platform. Presenters, chairpersons and participants will be connected via internet connections in virtual rooms, with the option of communicating with each other. An online network will also be available in special virtual rooms during coffee breaks. The presentations will be prepared and operated by Google Slides. Relevant information with instructions on how to prepare presentations in Google Slides will soon be send to the authors. Participation in the conference without presentation will also be possible, after receiving a special access code.

More information soon.
