Article Abstract
We employed a three-phase approach, culminating in a randomized controlled trial, to assess the efficacy of 3D-printed liver models in hepatobiliary surgical planning. Phase one involved developing and selecting 35 optimal 3DP models based on timeliness, cost, precision, and alignment with digital simulations. Phase two utilized deep learning algorithms to optimize the 3D reconstruction process, significantly enhancing efficiency and accuracy compared to manual segmentation. In phase three, a randomized controlled trial with 64 patients compared surgical outcomes between those planned with AI-enhanced physical 3DP models and those with traditional digital simulations. Results demonstrated that 3DP models were produced rapidly (3.52 h at $152 each) with high precision, AI-assisted reconstruction reduced processing time (303.5 vs. 557 min), and patients using AI-enhanced physical 3DP models experienced less intraoperative blood loss. Integrating deep learning with 3D printing offers a cost-effective, scalable method to enhance surgical planning and outcomes in hepatobiliary surgery.

Introduction: Three-dimensional printing (3DP) technology has increasingly gained attention in orthopedic oncology, where complex tumor resections and reconstructions demand high precision. 3DP enables the creation of patient-specific models and prostheses, which can improve postoperative quality of life for patients while assisting surgeons in preoperative planning, enhancing surgical accuracy, and improving outcomes in complex oncologic cases. Despite its potential, comprehensive data on the effectiveness and applications of 3DP in orthopedic oncology are limited.

Marginal and internal fit of single crowns is critical for clinical success. Further research is necessary to investigate the effects of various conventional and additive/subtractive manufacturing techniques on restoration fit, particularly for different tooth types. This in vitro study compared the fit of anterior and posterior crown substructures fabricated using five techniques: milled wax patterns for casting (CAW), 3D-printed polymer patterns for casting (3DP), direct metal laser sintering (DMLS), selective laser melting (SLM), and manual wax carving (Cast).

This paper describes the design and fabrication of the first fully 3D-printed (3Dp) solid-contact (SC) ion-selective electrode for use in potentiometric sensing. This sensor, constructed from stereolithographically printed Na-ion-selective membranes and carbon-infused polylactic acid transducers, fabricated via fused-deposition modelling, demonstrates the diversity and extreme utility of 3D-printing in electroanalysis. We demonstrate the ability to manipulate and fine-tune transducer hydrophobicity based on print angle and print thickness, leading to highly stable (∼20 μV drift per hour) 3Dp-Na-ISE.

Surface modification of bioactive materials and implants can contribute more efficiently in the bone healing process. Amine modification of mesoporous bioactive glass (MBG) enhances its suitability by improving cell adhesion, pH stability, degradation control, and osteogenic potential in bone tissue engineering application. In this study, amine-grafted MBG was incorporated into PLA (30:70 organic:inorganic) to fabricate 3D printed (3DP) composite scaffolds, followed by surface decoration with branched PEI (MW ∼ 1200).

Currently, most amorphous solid dispersion (ASD) formulations contain a single polymer to stabilize an amorphous drug. However, a single polymer has a limited ability to form strong drug-polymer interactions, resulting in poor drug loading (<30 % w/w) and a high pill burden. This research explored binary polymer combinations, specifically Copovidone/HPMC ASLF and Copovidone/Eudragit EPO, to address single polymer limitations.
