Magneto‐responsive fibers and fabrics for soft systems

FlexMat, EarlyView.
Abstract The combination of functional materials in fiber form has led to a surge in the integration of functional fibers and fabrics into soft systems that span sensing, communication, and actuation domains. A key subset is magnetic fibers and fabrics.

Evaluation of 6‐Month Knowledge Retention and Satisfaction After Pedagogical Escape Games in Dentistry

Journal of Dental Education, EarlyView.
ABSTRACT Purpose To evaluate 6‐month knowledge retention and long‐term satisfaction after two pedagogical escape games (PEGs) addressing foundational (3D printing) and clinical (pediatric dentistry) content in a dental curriculum. Methods In this monocentric serial cross‐sectional study, immediate post‑PEG knowledge was assessed in fifth‑year dental ...

Surface Flatness Measurement in Stereolithography

, 2000
The majority of stereolithography systems use a recoating method to add a layer of liquid resin during the build process. The various methods for doing this result in a free liquid surface, which must be flat to enable the build process to continue.

Perceived Educational Value of a Self‐Developed 3D‐Printed Pediatric Dentistry Simulator

Journal of Dental Education, EarlyView.
ABSTRACT Purpose To design and assess a 3D‐printed pediatric dentistry simulator and to evaluate its perceived educational value and realism through student and expert feedback. Methods A maxillary simulator that is mountable on phantom heads was developed and produced by desktop stereolithography with single‐use inserts, enabling proximal caries ...

3D‐Printed Sinus Lift Training Models as an Educational Tool for Dental Students

Journal of Dental Education, EarlyView.
ABSTRACT Purpose/Objectives The aim of this study was to evaluate whether 3D‐printed models can be an inexpensive and suitable way to train dental students to perform a sinus lift. Methods The sinus lift model was created using CAD/CAM technology. Approximately one year prior to their final examination, thirty‐one dental students evaluated and tested ...

3D Printing a Clinically Available Solution From Plaster‐Based Positives in Superficial Radiation Therapy

Journal of Medical Radiation Sciences, EarlyView.
This study compares two techniques for creating lead shielding masks to replace the current process for superficial/orthovoltage facial radiotherapy: Plaster Cast Positive Mould (PCPM), CT Scanned 3D Print (CT3DP), and Optical Scan 3D Print (OS3DP). CT3DP was found to be more accurate and preferred over OS3DP.

Chiral Quasi‐BICs Stemming From a Γ‐point Degeneracy

Laser &Photonics Reviews, EarlyView.
Band degeneracies universally exist in 2D periodic systems. However, the studies on the intrinsic properties of those isolated points remain limited. By exploring 3D chiral perturbations, chiral quasi‐BICs are achieved through a Γ‐point degeneracy in resonant metasurfaces with C4 symmetry.
