“…The measurement was carried out in air from 50°C to 1000°C with a heating rate of 3°C/min. According to the TG curve, about 0.85% of the weight loss was produced from 140°C to 217°C where the main change is related to the removal of physically adsorbed water. Afterwards, almost all of the polymer additives from green body were burnt out at temperatures ranging from 217°C to 571°C, resulting in obvious weight loss (18.59%).…”

Zirconia ceramics have shown a wide applicable prospect in dental prosthetics because it possesses excellent mechanical performance and biocompatibility. The rheological behavior and curing properties of zirconia stereolithography slurry were studied, as well as the microstructure of the green, pyrolyzed, and sintered body.Variquat CC-42 NS was proved to be effective for zirconia powder dispersing in photocurable resin (SP-RC700). The curing characteristic of slurry showed that the depth of penetration tended to increase with the solid loading. Finally, the zirconia all-ceramic crowns were fabricated via DLP-based stereolithography printer. Results showed that the particles were evenly distributed in the cured resin matrix without obvious agglomeration, and the interlayered structure disappeared after binder burnout. The sample with a major crystalline phase of tetragonal zirconia and a porosity of 10(1)% were obtained after sintering at 1550°C.

“…An increase in the concentration of Disperbyk-111 caused a decrease in viscosity and 3 wt% of this dispersant provided a 40 vol% ceramic slurry viscosity suitable for the suitable for DLP additive manufacturing (2.3 Pa.s at 30 s -1 ). The shear-thinning behavior presented by these suspensions is characteristic of VP ceramic slurries 21,42,43,47,[49][50][51][52][53] . Such behavior is desirable in VP 1,54,55 because it avoids sedimentation of the suspension in a stationary state, and adequate flow when a shear rate is applied to the slurry 32 .…”

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.

“…SLA may be used to fabricate product using diverse range of materials. For example, Liu et al [29] demonstrated ZrO 2 -Al 2 O 3 composite ceramic parts using UV curable ZrO 2 -Al 2 O 3 composite ceramic pastes based on the SLA process with subsequent debinding and sintering process. Karakurt et al [30] created personalized drugs and medicines geometries with novel biocompatible photochemistry consisting of ascorbic acid (AA) encapsulated in a poly(ethylene glycol) dimethacrylate (PEGDMA)-based polymer network and polymerized using riboflavin as a photoinitiator.…”

The use of additive manufacturing (AM) has moved well beyond prototyping and has been established as a highly versatile manufacturing method with demonstrated potential to completely transform traditional manufacturing in the future. In this paper, a comprehensive review and critical analyses of the recent advances and achievements in the field of different AM processes for polymers, their composites and nanocomposites, elastomers and multi materials, shape memory polymers and thermo-responsive materials are presented. Moreover, their applications in different fields such as bio-medical, electronics, textiles, and aerospace industries are also discussed. We conclude the article with an account of further research needs and future perspectives of AM process with polymeric materials.
