This article highlights three-dimensional printing as a rapid pro to typing process that builds objects by depositing a material such as thermoset resin in layers one on the other. Desktop 3D printers are now relatively inexpensive. Traditionally, printed models have been dipped in an epoxy resin. FigurePrints uses an automated system from xlaForm that allows parts to be infused in bulk in a heating machine. This method cuts processing time and labor costs, but is still time-consuming and allows processing only in batches. Wohlers is also watching Shapeways of Eindhoven in the Netherlands, which has married 3D printing with the crowdsourcing model now being blazed on the Internet. This model asks Internet users to design or create products and then rank the results. At Shapeways, which is actually a business incubator sponsored by Koninklijke Philips Electronics NV, consumers upload their own 3D models, which are then printed and shipped. Users can also purchase models.

Parental prenatal counseling is of paramount significance since parents often experience an emotional crisis with feelings of disappointment and helplessness. Three-dimensional (3D) printed model of the unborn child’s face presenting with cleft lip and palate, based on ultrasonographic information, could be used to provide visual 3D information, further enhancing the prospective parent’s comprehension of their unborn child’s pathology and morphology, helping them to be psychologically prepared and improving the communication with the caretaking team. Prospective parents appreciate if prenatal counseling is available with the most detailed information as well as additional resources. The technique necessary to create 3D models after ultrasonographic information is explained, and the related costs are evaluated. The use of such models in parental education is then discussed.

Dentistry is truly a great profession and recently it is coming to the terms of use of technology and tech-savvy dentists, who nowadays use smart devices to make their life easier. Researchers are constantly innovating to integrate techno-logy into dentistry. Of all the latest technological innovations in dentistry, the most talked about innovations are three-dimensional (3D) printing and cone beam computed tomography (CBCT), which have made the treatment planning and execution a whole lot easier. Three-dimensional printing like CBCT has been gaining much popularity in the masses. Three-dimensional printing technologies are evolving rapidly in the recent years and can be used with a wide array of different materials. In addition to rapid prototyping, the dominant use in the past, they are now being used in all manner of manufacturing applications in a diversity of industries such as sports goods, fashion items such as jewelry and necklaces to aerospace components, tools for automobile industry, and medical implants also in dentistry for producing models, making scaffolds, etc. In future, 3D printing has ability to change the way many products are manufactured and produced and bring an era of ‘personal manufacturing’. This article introduces 3D printing and gives little information about the technology behind the working of 3D printers. It also gives information about the applications of 3D printers and materials most often used for 3D printed scaffolds for periodontal regeneration.

The pandemic caused by the new coronavirus has placed national health systems of different countries in difficulty, and has demonstrated the need for many types of personal protective equipment (PPE). Thanks to the advent of new three-dimensional printing technologies, it was possible to share print files (using stereolithography (stl)) quickly and easily, improve them cooperatively, and allow anyone who possessed the materials, a suitable 3D printer and these files, to print. The possibility of being able to print three-dimensional supports, or complete personal protective equipment has been of incredible help in the management of COVID-19 (Coronavirus Disease 2019). The times and the relatively low costs have allowed a wide diffusion of these devices, especially for the structures that needed them, mainly healthcare facilities. 3D printing, now includes different fields of application, and represents, thanks to the evolution of methods and printers, an important step towards the “digital world”.

Guidance Model

The application of three-dimensional (3D) models in the medical field has become popular. However, the accuracy of 3D models for surgical guidance varies among different materials and 3D printing technologies, such as printing machine usage. Objectives: This study aims to obtain more information about the effect of three different materials printed using a fused deposition material printer from the same digital data source. This study also aims to compare, analyze, and test the materials’ ability. Methods: Each of the filament materials (acetylbutane stearate [ABS], polylactic acid [PLA], and high-impact polystyrene [HIPS]) are printed at two infill densities, their weight, volume, and dimension are measured, and infill materials are prepared. Printing time is estimated and calculated on the basis of printing properties by using Simplify3D© software. The strength and surface tension of each sample are examined via a drilling test. Results: PLA is better than ABS and HIPS for printing our 3D model because of its properties. Conclusion: Ideal 3D materials for printing 3D models should fulfill the criteria on accuracy, strength, weight, and durability for usage. However, production time and cost should also be considered.

Abstract Three-dimensional printing is a valuable modality with broad clinical applications. Hip preservation surgery outcomes are dependent on correction of morphological abnormalities that may be optimally visualized with three-dimensional models. To assess the efficacy of three-dimensional models for patient and trainee education and to determine its benefits during pre-operative planning in hip preservation surgery. Sixteen patients with hip pathology were selected. Computed tomography was utilized to generate three-dimensional models. Customized Likert-style questionnaires were given to 10 hip preservation surgeons, 11 orthopedic surgery residents and 10 patients. All residents strongly agreed or agreed that the three-dimensional hip models helped them to understand patients’ pathology. All but one patient agreed that the models assisted in their understanding of the treatment plan. Surgeons concurred that although they do not routinely order three-dimensional models, their use would improve trainee and patient education, especially when treating atypical osseous pathomorphologies. Three-dimensional models are tools that can help surgeon, trainee and patient understanding and participation in treatment of complex hip disorders. Patients and trainees agree that the prototypes enhanced their educational experience, as the surgeon can directly demonstrate complex morphological abnormalities. Trainees can therefore gain a better understanding of hip pathologies and treatment. As patients better understand their hip disorder, they can more fully participate in shared treatment decision-making. Level of Evidence Level IV, Retrospective Case Series

AbstractWe propose a layout estimation method for multi-layered ink using a measurement of the line spread function (LSF) and machine learning. The three-dimensional printing market for general consumers focuses on the reproduction of realistic appearance. In particular, for the reproduction of human skin, it is important to control translucency by adopting a multilayer structure. Traditionally, layer design has depended on the experience of designers. We, therefore, developed an efficient layout estimation to provide arbitrary skin color and translucency. In our method, we create multi-layered color patches of human skin and measure the LSF as a metric of translucency, and we employ a neural network trained with the data to estimate the layout. As an evaluation, we measured the LSF from the computer-graphics-created skin and fabricate skin using the estimated layout; evaluation with root-mean-square error showed that we can obtain color and translucency that are close to the target.
