Special Issue Information

Dear Colleagues,

Humanity has always had aspirations of achieving the impossible. Thus, although a few decades ago the ability to print a rocket or a heart on a printer sounded like science fiction, now many people have a 3D printer at home.

Additive manufacturing, also known as 3D Printing, dates back to the mid-1980s. The first commercial additive manufacturing machine (SLA-1) was sold in 1988 by 3D Systems. Since then, the research results of thousands of researchers and engineers who are in love with 3D printing have found their way into the fields of aircraft engineering, rocket science, propulsion systems, medical products, microcircuits, the food industry, etc. Additive technologies have made it possible to create parts of a new, more complex shape that could not be made using traditional production methods (stamping, molding, milling and casting) from polymers, ceramics and metals.

Research into improving the properties of materials already in use, as well as introducing completely new materials into additive technologies is of particular importance as a pillar of further development as a response to the current economic needs of rapid and low-cost manufacturing. This Special Issue is the right place to present current needs and opportunities for future improvements or new materials for additive manufacturing.

We invite you to submit a manuscript for this Special Issue. Full papers, communications and reviews are all welcome.

The application of additive manufacturing method such as material extrusion (MEX) allows the successful fabrication of ceramic products, including multi-ceramic products. Promising materials in this research area are TiO2 and ZrO2 ceramics, which can be used in electrical and electronic engineering. The aim of this work is to investigate the possibility of fabricating TiO2/ZrO2 multi-materials from ceramic pastes that can be used in the MEX. In this work, defects, chemical and phase composition, and microhardness were analyzed in multi-ceramic samples after sintering. Multi-ceramic TiO2/ZrO2 samples after the sintering process without interlayer could not be fabricated due to a too large difference in shrinkage between TiO2 and ZrO2. The samples with one and three interlayers also have defects, but they are less significant and can be fabricated. The average hardness for the TiO2 zone was 636.7 HV and for the ZrO2 zone was 1101 HV. In the TiO2 zone, only TiO2 phase in rutile is observed, while in the interlayer zones, in addition to rutile, ZrO2 and ZrTiO4 are also present, as is a small amount of Y2O3. In the zone ZrO2, only the ZrO2 phase is observed. The chemical analysis revealed that the interlayers comprise sintered ZrO2 granules enveloped by TiO2, ZrO2, and ZrTiO4. Full article
