“…To accommodate the needs for nanotechnology various chemical deposition [ 13 , 14 ] or wet etching [ 15 , 16 ] techniques were employed. At the same time, direct [ 17 , 18 ] and indirect [ 19 , 20 ] additive 3D manufacturing of glass was demonstrated. However, in all of the highlighted processes, severe drawbacks and compromises are limiting their applicability.…”

The rapid expansion of femtosecond (fs) laser technology brought previously unavailable capabilities to laser material processing. One of the areas which benefited the most due to these advances was the 3D processing of transparent dielectrics, namely glasses and crystals. This review is dedicated to overviewing the significant advances in the field. First, the underlying physical mechanism of material interaction with ultrashort pulses is discussed, highlighting how it can be exploited for volumetric, high-precision 3D processing. Next, three distinct transparent material modification types are introduced, fundamental differences between them are explained, possible applications are highlighted. It is shown that, due to the flexibility of fs pulse fabrication, an array of structures can be produced, starting with nanophotonic elements like integrated waveguides and photonic crystals, ending with a cm-scale microfluidic system with micro-precision integrated elements. Possible limitations to each processing regime as well as how these could be overcome are discussed. Further directions for the field development are highlighted, taking into account how it could synergize with other fs-laser-based manufacturing techniques.

“…Following the approach of SfC [14] we represent the solution space of our shape reconstruction as a height field h ∈ R n×n over the flat base substrate of known thickness d. To simulate the result-Figure 2. Schematic sketch of in-situ feedback during production: compared to the usual setup [37], this includes only two additional components: a light source above and a camera below the substrate to generate and capture caustic images.…”

“…The prior can be hand-crafted [14] or learned from data as in this work. This is motivated by the fact that the generating process we wish to consider here is 3D printing by laser glass deposition [37], which invalidates very small rapidly changing structures like in the reconstruction of Fig. 3.…”

“…It has gained particular interest owing to its advantages of material saving, high production efficiency, and low cost [1][2][3][4][5][6]. In recent decades, with the rapid development of laser AM technology, the range of materials that can be processed has developed from metals [7,8], ceramics [9,10], and polymers [11,12] to the current transparent materials such as glass [13][14][15][16]. It is worth noting that its process parameters vary with the performance, application, and material of the product.…”

Laser-based additive manufacturing (AM) of glass is rare and complex, which involves highly non-linear thermodynamic problems. The temperature gradient is essential in analyzing the residual stress distribution and thermal deformation. At present, there is no accurate formula to describe the temperature field, and it is also difficult to measure the real-time temperature of the molten pool during the AM process. The numerical method in predicting the temperature field of fused silica glass laser becomes attractive. In this work, a finite element (FE) model for laser AM of quartz glass is established, and the temperature field of laser AM of quartz glass based on the principle of coaxial powder feeding is simulated by combining a moving heat source and birth-death element method. The temperature fields under different laser powers and scan speeds are investigated respectively. Results show that the peak temperature increases with the decrease of laser scan speed and the increase of laser power; The temperature of the upper layer is higher than that of the lower layer because of the heat accumulation effect; The increment rate of laser power and scan speed is set in the range of - 12.5% to 37.5% to ensure the temperature of AM region is slightly above the melting point of quartz glass. It is found that the influence of power change on the temperature field is more significant than that of scanning speed. Meanwhile, the peak temperature-dependent linearly on those two variables disused. The results provided here are instructive for subsequent laser AM of glass material including coaxial powder feeding method, powder cladding, etc.
