Summary: Hybrid additive manufacturing combines the advantages of additive and subtractive manufacturing to produce parts with complex geometries, improved surface finish, and precise dimensional accuracy. CAM software plays a crucial role in orchestrating the machine toolpathing for both deposition and machining processes. Different hybrid systems can benefit from optimized toolpath planning to improve the microstructure, mechanical properties, porosity, and residual stress of the final fabricated part.

Summary: The review discusses the recent scientific literature on AM fabrication of drug delivery scaffolds for TE, focusing on bioactive molecule loading into 3D porous scaffolds and their release effects on cell fate and tissue growth. strategies such as bioprinting were reviewed to achieve passive and stimuli-responsive drug delivery scaffolds for TE and cancer precision medicine. The integration of AM, microfluidic, and soft lithography is highlighted for enhancing 3D porous scaffold bioactivation towards functional bioengineered tissues and organs.

Summary: This article introduces a method of using digital twin technology to build a high-fidelity process model and optimize process plans. By feeding surface inspection data of parts back to the CAPP system and associating it with the digital twin process model, and then using the Poisson reconstruction algorithm for simulation, it is found that the digital twin model can improve simulation accuracy.

Summary: Orthognathic surgery is a surgical procedure that can correct both aesthetic and functional aspects of TMJ and facial skull district deformities. This research aims to define a methodology for surgery planning and designing and manufacturing templates using Reverse Engineering (RE), Virtual Surgery Planning (VSP), Computer Aided Design (CAD), Additive Manufacturing (AM), and 3D visualization. The proposed method allows complete planning of the surgery and introduces novel evaluation methods and personalized surgery options.

Summary: The purpose of this systematic review and meta-analysis was to compare the in-brace correction angle of computer-aided design and computer-aided manufacturing (CAD/CAM)-manufactured braces or the CAD/CAM-manufactured braces integrating with biomechanical simulation with that of manually manufactured braces for adolescent idiopathic scoliosis patients. The results showed that CAD/CAM-manufactured braces did not demonstrate significant advantages over manually manufactured braces in terms of in-brace correction angle. Further high-quality clinical studies following Scoliosis Research Society (SRS) guidelines with long-term follow-up are needed to provide more solid conclusions and recommendations for clinical practice in the future.

Summary: This systematic review and meta-analysis compared the accuracy of removable partial denture (RPD) frameworks fabricated by computer-aided design/ computer-aided manufacturing (CAD/CAM) systems and conventional casting methods. The study found that the fit accuracy of CAD/CAM-fabricated frameworks was lower than that of frameworks produced by the conventional casting method.

Summary: Computer Aided Design (CAD) is a set of techniques that automate the designing and drafting of 2D and 3D models using computer programs. The quality of CAD software is crucial in ensuring the reliability of the designed models. Software testing is an important way to detect defects in CAD software development. This paper proposes an approach, PriorCadTest, to learn and prioritize test cases for CAD software, and evaluates its effectiveness on a real-world CAD project.
