“…Combined with the idea of regular distribution and random distribution, we conducted ICP registration based on the grid voxel central point set 26 and ICP registration based on random generating points within the grid to perform comparative experiments. ICP registration based on the grid voxelized center point set is shown in Supplementary Digital Content, Table 3, http://links.lww.com/SCS/D779.…”

results based on real clinical data demonstrate the feasibility and effectiveness of the proposed method. With the development and popularity of digital workflows, it is hoped that the work proposed in this paper can be more widely applied in dental clinical experiments in the future to facilitate doctors and patients in better carrying out their work. To overcome the problems and prospects raised in this paper, we will try to break through step by step in the future and constantly improve.

“…The print control software orchestrates the activity of each subsystem to execute successful prints. When a build job has been defined, the print control software processes the file in a voxel representation by rendering the geometries at the printer's resolution 51,52 . The voxelization step uses ray tracing to quickly render the input geometries.…”

Recreating complex structures and functions of natural organisms in a synthetic form is a long-standing goal for humanity1. The aim is to create actuated systems with high spatial resolutions and complex material arrangements that range from elastic to rigid. Traditional manufacturing processes struggle to fabricate such complex systems2. It remains an open challenge to fabricate functional systems automatically and quickly with a wide range of elastic properties, resolutions, and integrated actuation and sensing channels2,3. We propose an inkjet deposition process called vision-controlled jetting that can create complex systems and robots. Hereby, a scanning system captures the three-dimensional print geometry and enables a digital feedback loop, which eliminates the need for mechanical planarizers. This contactless process allows us to use continuously curing chemistries and, therefore, print a broader range of material families and elastic moduli. The advances in material properties are characterized by standardized tests comparing our printed materials to the state-of-the-art. We directly fabricated a wide range of complex high-resolution composite systems and robots: tendon-driven hands, pneumatically actuated walking manipulators, pumps that mimic a heart and metamaterial structures. Our approach provides an automated, scalable, high-throughput process to manufacture high-resolution, functional multimaterial systems.

“…We first convert the input model into a voxelization where voxels intersected by the scene geometry are detected. This conversion can be performed in the GPU (Dong et al, 2004). Our current implementation is based on the voxelization algorithm by Eisemann and Décoret (2006).…”
