In 2016, he starred alongside Lena Headey and fellow Australian Eliza Taylor in the police drama film Thumper. Webber received praise for "mastering Oswald's peculiar speech pattern and growing sense of paranoia." After he was cast, he then read the novel on which it was based, as well as other books about the assassination. He got the role after sending in an audition tape, which he had two days to prepare for, including watching newsreels of Oswald and listening to clips of his voice. Abrams-produced 11.22.63 was his first in the United States. In 2015, Webber played Ryan Kelly, a stalker, on Australian soap opera Home and Away. He also had roles on All Saints and in the miniseries Devil's Dust. From 2009–2010, he portrayed Darius Pike on the TV series K-9. His first acting experience was on the 2009 film The Combination. Webber worked as a rope access technician on wind turbines. He was a trampolinist and performed in the 2000 Summer Olympics closing ceremony. Webber grew up on the New South Wales Central Coast and attended Green Point Christian College. Among his best known roles, Webber has portrayed Mötley Crüe lead singer Vince Neil in the 2019 film The Dirt, Lee Harvey Oswald in the American science fiction thriller miniseries 11.22.63 and Lewis Wilson in the Netflix original series The Punisher. Scalebars are all 5 mm, but do not include magnification by the vial.Daniel Peter Webber (born 28 June 1988) is an Australian actor. For the longer wait time, the polymerized region is thicker due to diffusion. c Raw scattering images of the thin disk region at the onset of polymerization of the thick disk. The resulting dose diffusion coefficients for each resin are noted next to teach curve. The curves are fits to the data assuming dose diffusion (dotted curves indicate lower and upper bounds, see text). Each datapoint represents a separate individual experiment. The datapoints correspond to a polymerization threshold of 2 gray levels above the background. The upper and lower bounds of the error bars correspond to measurements of T ex when setting polymerization threshold at 3 and 1 gray levels above the background, respectively. b Experimental data points for the diffusion experiment showing the relationship between extra exposure time needed to polymerize the thin disk ( T e x) and the delay time t d e l a y. For shorter wait times, a small extra exposure time is required to polymerize the thin disk. Raw OST images for each of these steps are shown in the middle and bottom rows for wait times of 166 s and 1270 s, respectively. As exposure continues, the entire thick disk (d 1 region) polymerizes. The total time over which diffusion occurs is approximated as t d e l a y (see Eq. 1). First, this extra dose elevates the dose in the thin disk region to polymerization (d 0 polymerization onset), after an extra time T e x of exposure. After the wait period, a second exposure occurs encompassing a thick disk (5 mm) is applied. The wait time is changed for each experiment in the series. This is followed by a wait period of duration t w, during which there is no light. First, a thin disk region (thickness 0.5 mm) is exposed for duration t a p p = 40 s (exposure 1). These results position volumetric additive manufacturing as a mature 3D printing method, all but eliminating the gap to industry-standard print fidelity.Ī Top row is a schematic of the experiment. This enables prints previously beyond the capabilities of volumetric additive manufacturing, such as a complex gyroid structure with variable thickness and a fine-toothed gear. We develop a model that quantitatively predicts the variation of print time with feature size and demonstrate a deconvolution method to correct for this error. Here, we uncover the reason for this limitation: light dose spread in the resin due to chemical diffusion and optical blurring, which becomes significant for features ⪅0.5 mm. Currently, volumetric additive manufacturing prints suffer from systematic undercuring of fine features, making it impossible to print objects containing a wide range of feature sizes, precluding effective adoption in many applications. Their widespread adoption, however, demands significant improvement in print fidelity. Volumetric additive manufacturing techniques are a promising pathway to ultra-rapid light-based 3D fabrication.
