During the COVID-19 pandemic Juan Segurola through its company 3Dresyns committed to supply biocompatible 3D resins for free and at low cost to produce respirator parts and other needed parts for hospitals use, as well as antiseptic cleaners and cleansing additives which were available online for its distribution Worldwide. Read 3Dresyns contribution to COVID-19 Emergency.
Our goal was to support society worldwide in this difficult pandemic situation to those lacking economical resources due to confinement by donating and selling at low cost 3D resins for emergency printing of respirator parts, turbines, masks, swabs, etc. A selection of products were designed for Emergency Printing "EP" of respirator use parts, masks, etc, which are still available with high discounts for non profit applicants.
In 2012 Segurola began a collaboration with the NGO CC and carried out a project of ambulatory medical assistance and analysis of water quality in one of the poorest countries in the world, Mali, a country in sub-Saharan Africa, where he decided up to date to finance ambulatory medical projects, given the low outpatient coverage of the country.
In addition, Segurola has also developed several eco-sustainable bio-construction projects built with natural and recycled materials, such as the use of traditional lime mortars for construction and of metal containers, solar panels, the development of eco-sustainable gardens with native flora to minimize dependence on irrigation.
Segurola is concerned about the United Nations 6 goal; availability and sustainable management of water and sanitation for all, since it is one of the main problems facing mankind. He has identified fog collection through the design of functional cost effective fog nets, since special attention needs to be paid to the used material and the design of the net since water collection capacity depends on few variables, such as the thermal conductivity of the material, its morphology, such as its porous size and shape, the fog net thickness, etc. As a non-profit project, he is interested in the design of affordable biodegradable materials suitable for making cost effective fog nets.
He is interested in research of biodegradable and bio-based plastics "bioplastics", as well as in thermally conductive metal mesh, all with varying controlled pore sizes and shapes as candidates for more efficient affordable materials for fog nets even in dry regions of the world.
Some of the mesh yield increased durability (for the stainless steel ones), biodegradability (for the bio-based ones), and water condensation capacity than the commonly used non biodegradable Raschel mesh which has too big pore sizes (low condensation yield or harvesting) and are made of petrochemical based materials, such as polyethylene and polypropylene.
Segurola has started to evaluate and develop new types of 3D mesh to eliminate clogging, improve drainage and overall increase efficiency of fog water collection, since mesh efficiency is dependent on several variables, such as wind-speed, moisture content in the air, 3D pattern design (parallel vertical vs horizontal single and multi-layer structures, biomimetic designs, etc), surface thermal conductivity, surface area, surface tension, surface hydrophillicity-hydrophobicity, water droplet size, etc.
