Mask image projection based on stereolithography is an additive manufactured technology based on a Frontal Photopolymerization Process. Therefore, photocurable resins are used to build-up parts layer by layer. In this paper, alumina particles have been used as a reinforcement filler in order to improve the material stress-strain behaviour. In addition, the increment of the photoconversion ratio is a key factor to enhance the mechanical properties. Consequently, a numerical model has been used to determine the optimal printing parameters to enhance the elastic mechanical properties of printed parts according to the characteristics of photocurable materials. Stable and homogeneous reinforced materials have been obtained with an alumina content ranging from 5 to 15 wt%. Furthermore, the compression behaviour of reinforced materials has been analysed by means of experimental tests. The results show an enhancement of mechanical properties after the addition of reinforcement fillers, obtaining a maximum improvement in 10 wt% of solid load content. Finally, the influence of the sample’s orientation on the construction platform has been discussed.

“…132,138 This is often due to the thermal decomposition of the organic binder into gases, which, if not carefully managed, can compromise the shape fidelity and mechanical properties of the final ceramic part. 139 Multiple factors have been found to influence the generation of these gases and their ability to diffuse non-destructively from the body, such as the ceramic particle sizes in the slurry, 140,141 the print exposure parameters, 142 part design 141,143 , and the thermal debinding conditions. [144][145][146] For example, Zhou et al showed that thermal debinding of 3D alumina green bodies in air resulted in significantly more defects compared to when the procedure was conducted in vacuum.…”

Vat photopolymerization (VP) is one of the most remarkable additive manufacturing techniques today and has been used for a variety of applications, from materials research to product manufacturing. The main challenge with VP is the limited choice of compatible materials, which motivates significant interest in VP materials development. We provide a brief overview of the materials that are currently accessible via VP and highlight recent advances in the field. We also provide perspective on expanding the library of materials compatible with VP using in situ materials synthesis.

“…Although a higher percentage of ceramics is desired for the slurries used for DLP additive manufacturing, preliminary analyzes need to be performed at lower concentrations in order to find suitable components, otherwise, most of the initial test suspensions would have very high viscosities, outside the measurement range of the viscometer, and could not be compared. In addition, high solid loading makes it difficult to visualize sedimentation and related works performed these tests in a concentration below 20 vol% 6,26,31,38,43 .…”

“…On the other hand, the higher the solid load, the higher the viscosity of the slurry 4 . Some studies have used high viscosity (up to 18.8 Pa.s) ceramic slurries in equipment with special system for forming new layers such as Admaflex 130 (ADMATEC Europe BV, The Netherlands) 5 and Ceramaker 300 system (3D CERAM, France) 6 . However, suspensions whose viscosities do not exceed 3 Pa.s are preferred for common VP equipment 2,3,7 .…”

Vat photopolymerization (VP) stands out among ceramic additive manufacturing processes for its ability to print sub-100 micrometer complex features. One of the main challenges of this process is the preparation of a homogeneous and stable ceramic slurry with a high solid load and low viscosity. In this work, different dispersants and resins were tested, aiming to provide a solvent-free slurry suitable for DLP additive manufacturing. Disperbyk-111 and PEGDA 250 stood out in the tests, providing a 40 vol% ceramic slurry with no noticeable sedimentation and viscosity of 2.3 Pa.s at 30 s -1 despite the relatively high specific surface area (15 m 2 /g) of the 3Y-TZP powder used compared to powders usually used for VP slurries. The adsorption of Disperbyk-111 on ceramic particles surface was investigated by FTIR. Finally, ceramic bodies were 3D printed, debound and sintered at 1500 ºC for 2 h, confirming the ability to manufacture detailed dense ceramic parts.
