Scientists have developed new ceramic 3D printing materials that are economical and affordable

Researchers at the Slovak University of Science and Technology have developed a new ceramic 3D printing material specially designed for low-cost FFF machines.
?? Unlike the existing entry-level ceramics, the new material developed by the team is composed of a PVA binder and a mullite matrix, which can be extruded from a standard 0.
4 mm nozzle without the need to increase viscosity or system adjustments.
The formula can also be post-processed without the use of expensive professional furnaces, which makes it an economical ceramic that offers great potential for potential 3D printing enthusiasts.
?? In order to make ceramic materials easier to process, Slovak scientists designed a new formula.
By combining mullite powder, aliphatic acids and thermoplastic polymers, the team was able to create filaments with a diameter of 1.
75 mm, which can be processed with a 0.
4 mm print head.
After optimizing the raw materials, the researchers connected the 600 and 400 micron print heads to the Leapfrog Creatr 3D printer and produced a set of cylindrical samples.
Each part was patterned with mini rectangles to observe printing errors, but the team observed no obvious cracks or nozzle clogging.
