“…In DLP, each layer of the resin is exposed all at once to the light source and then cured simultaneously. This allows considerably shorter building times than the point-by-point printing with a laser employed in SLA [ 2 , 3 , 6 ].…”

There is need for developing novel conductive polymers for Digital Light Processing (DLP) 3D printing. In this work, photorheology, in combination with Jacobs working curves, efficaciously predict the printability of polyaniline (PANI)/acrylate formulations with different contents of PANI and photoinitiator. The adjustment of the layer thickness according to cure depth values (Cd) allows printing of most formulations, except those with the highest gel point times determined by photorheology. In the working conditions, the maximum amount of PANI embedded within the resin was ≃3 wt% with a conductivity of 10−5 S cm−1, three orders of magnitude higher than the pure resin. Higher PANI loadings hinder printing quality without improving electrical conductivity. The optimal photoinitiator concentration was found between 6 and 7 wt%. The mechanical properties of the acrylic matrix are maintained in the composites, confirming the viability of these simple, low-cost, conductive composites for applications in flexible electronic devices.

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.

“…In addition, there are particular issues in the conventional processes [2]: (1) The shaping process of complex parts highly depends on the mold; (2) Sintered bodies often need additional mechanical post-processing; (3) Certain unique shapes (e.g., inner cavities/pores/groove) are difficult to generate using traditional ways. Recently, it has been of great interest to use the Additive Manufacturing (AM, also known as 3D printing) [3] technique in the ceramic industry to sidestep the issues mentioned above and could save up 80% of the fabrication cost of the ceramic parts [4]. Usually, AM is classified according to the material statement that is used (powder materials, solid materials, and liquid materials) [5] and the material accumulating (indirect, direct) [3].…”

“…Among the various AM techniques that be used for ceramic parts fabrication (three-dimensional printing (3DP) [9], stereolithography (SLA) [10], 3D gelprinting [11], a robocasting technique [12], direct inkjet printing (DIP) [13] and fused deposition modeling (FDM) [14], etc. ), digital light processing (DLP) [4,[15][16][17][18][19][20][21][22][23] is one of the most promising technique. These parts fabricated by this technique exhibit fine surface finishing and very high spatial resolution.…”

Zirconia is widely applied as an implant due to its’ excellent biocompatibility and mechanical properties such as high hardness and extraordinary resistance to wear and corrosion. However, these outstanding mechanical properties make it challenging to fabricate Zirconia into complex shapes using conventional manufacturing techniques. In the current study, the digital light processing method was used to manufacture the Zirconia part. Its mechanical property was evaluated via a three-point bending test with digital image correlation and fractography analysis. The 3D-printed Zirconia sample had a relative density of approximately 98.8% and a Vickers hardness value of 1128 HV. The flexural strength under parallel and vertical bending loads (with respect to the printing direction) were 56.63±3.97MPa and 70.98±6.62MPa, respectively. Surrounding by a few dense layers, the interior of the sintered sample was interlaced with needle-like and winding cracks. Under the three-point bending, the cracks initiated at the bottom surface due to the tension effect and propagated faster along the width direction than the thickness direction. There was a large area of cleavage morphology in the dense boundary layers, whereas the plastic fracture mode also appeared in the interior of the sintered samples. The digital light processing method is expected to be comparable to other advanced ceramic processing techniques for fabricating spatial lattice structural products.
