Dimensional Printing

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.

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”.

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.

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.

Dimensional Printing

In the last decade, the range of applications of three-dimensional printing (3D printing) in surgery has been expanding. In traumatology, orthopedics and rehabilitation of injuries of the upper limbs, there is growing interest in creating splints and orthoses that can take into account the individual anatomical features of the human body. Traditional orthoses and splints are not always convenient and can lead to undesirable consequences such as pain, swelling, pressure, or even lack of therapeutic effect. The prospects of 3D printing technology in medicine from the beginning of its mass introduction, the features of modeling, manufacturing and application of means for immobilization of injuries and diseases of the upper extremities according to domestic and foreign publications over the past 5 years are considered. The data on the functionality of 3D-printed tire structures and orthoses used to immobilize the upper limb are analyzed in comparison with traditional methods of fixation. Three-dimensional images of patients with injuries obtained using computed tomography, magnetic resonance imaging or using a 3D scanner can be used to create virtual 3D models of the forearm, wrist, fingers of the patient, and 3D printing with these anatomical models allows you to create personalized tires and orthoses. Thanks to an individual approach and the use of various solutions, three-dimensional printing can be widely used in traumatology and orthopedics. As a result of this approach, it becomes possible to implement and effectively use a variety of solutions that will find support in healthcare.
