Different from computed axial lithography, the resin vat does not rotate but rather moves linearly with a speed based on the frame rate used for the stack of layers' projection. The present chapter aims to give a comprehensive overview of a relatively recent 3D printing technology, completed ...
Both issues are remedied by altering the print speed and irradiation power. The boats presented here were printed using the same resin formulation as the Harvard University logo presented in panel c. Extended Data Fig. 4 Printing in the quadratic regime. The z distance from the focal point of...
Traditional 3D printing involves a layerwise deposition, whereas volumetric 3D printing is not layerwise. Instead the object being printed appears almost instantaneously within the photopolymer resin thanks to the laser solidifying the resin in three dimensions, super quickly. Goodbye layerwise deposition ...
5.It is also worth noting that the speed of sound in gas-saturated fluids is surprisingly low for a wide range of volumetric gas concentrations, and this has also been observed to produce antigravity effects3. 6.In UDT we have a unique approach to address the problem of transfer large volu...
To overcome geometric constraints and improve the printing speed of the conventional layer-by-layer vat polymerization-based AM technique, volumetric AM (VAM) has been developed7. VAM is based on the irradiation of a specific portion of the volume of a photosensitive resin by illumination with ...

For spherical volumes in a liquid of viscosity μ, a scaling law for the sedimentation speed v is \(v \propto \rho /\mu\). By selecting resins with µ > 10 Pa s, no significant sedimentation could be measured over the manufacturing time (20 s) of different relevant ...
This method has also been utilized to generate 3D images using a CGH displayed on an SLM27, and a high-speed projected spinning diffuser28 in place of a physical object. In our system, volumetric graphics are generated by a focused femtosecond laser in a drawing space generated by creating ...
An OCT system that includes a single axis (line) galvo scanner may be utilized to increase the acquisition speed of volumetric depth image(s), in some embodiments. In some embodiments, a full-field OCT system may be used. FIG. 9A illustrates an example meniscus prescription lens 905 for ...
