Abstract:
Purpose Poland’s syndrome patients often seek medical interventions to improve their aesthetic appearances. Design and manufacturing technologies make it possible to produce custom-made implants for such medical conditions. The purpose of this study was to compare the 3D digital geometries that were designed using Magics and Geomagic® Freeform® for two anonymous case studies of Poland’s syndrome patients. Design/methodology/approach Computed tomography data were acquired and processed in Mimics® to isolate the pectoralis muscles in STL file format. STL files were imported into Magics and Geomagic® Freeform® to design 3D digital geometries. Thereafter, comparative analyses were performed of the respective 3D digital geometries. Findings The angle between the vertical and oblique planes for both sides of the thorax was 6.5° for the female and 14° for the male. The surface areas and volumes of the geometries for the female were smaller than the male. Deviation analyses between the healthy side and reconstructed side of a thorax showed that 73 per cent of the test points for Magics and 78 per cent for Geomagic® Freeform® fell in the nominated tolerance region of >−5 and <+5 mm for the female. For the male, it was 83 per cent for Magics and 88 per cent for Geomagic® Freeform®. Practical implications Geomagic® Freeform® provides a more versatile design environment; however, the STL editor Magics may be an option to design 3D geometries for less intricate and less contoured implants. Originality/value This was a first attempt to compare the 3D geometries for Poland’s syndrome designed with an STL editor to those designed with a computer-aided design program.

Abstract:
Abstract This paper presents the results of comparative analysis of modeling accuracy the freeform surface constructed by using a variety of algorithms for surface modeling. Also determined the accuracy of mapping the theoretical freeform surface described by mathematical equation. To model surface objects used: SolidWorks 2012, CATIA v5 and Geomagic Studio 12. During the design process of CAD models were used: profile curves, fitting parametric surface and polygonal mesh. To assess the accuracy of the CAD models used Geomagic Qualify 12. On the basis of analyse defined the scope of application of each modeling techniques depending on the nature of the constructed object.

Abstract:
Reverse Engineering technology has became a widely applied technology, but it has never been used in the field of Clothing Design Engineering .This paper aims to explore how to constructing the three-dimensional entity model of clothing by Geomagic software, then introduce the files into Freeform software in order to redesign clothing. The matters need attention during the Point cloud select, t data processing and model reconstruction are described in detail. In addition, the paper discusses the best solution of importing into Freeform software in different situation, also discusses the processing procedure after importing.

Abstract:
Background: Unilateral coronal synostosis causing anterior plagiocephaly can result in restricted brain development and severe facial deformities. Various surgical procedures have been described for the correction of this deformity. Cranial vault remodeling, however, is associated with several complications. Occipitofrontal switching is a novel technique which utilizes a part of the contralateral occipital bone to reconstruct the frontal area. This is the first such case reported from India and first report where virtual mock surgery has been utilized for precision and improving outcome in this elegant procedure. Case Description: A 5-year-old girl presented with left anterior plagiocephaly. 3D image of her skull was reconstructed using Geomagic Freeform software (3D Systems, Rock Hill, SC). Measurements were accurately drawn and the procedure was practised virtually before performing the occipitofrontal switch on the patient. There were minimal blood loss and postoperative morbidity. One year follow-up of the patient showed optimal correction of the defect in the forehead region, symmetrical shape of the frontal and occipital region and symmetrical brows. Conclusion: The technique of occipitofrontal switch for correction of anterior plagiocephaly is an elegant procedure with good functional and aesthetic outcome.

Abstract:
The aim of this systematic review was to gather the clinical and laboratory applications of CAD/CAM technology for preoperative planning, designing of an attachment system, and manufacturing of nasal prostheses. According to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, an electronic search was carried out. Only human clinical studies involving digital planning for the rehabilitation of facial defects were included. A total of 21 studies were included with 23 patients, which were virtually planned through different planning software. The most common preoperative data for digital planning were CT scans in nine cases, CBCT in six cases, and laser scans in six cases. The reported planning softwares were Mimics in six cases, Geomagic Studio software in six cases, ZBrush in four cases, and Freeform plus software in four cases. Ten surgical templates were designed and printed to place 36 implants after digital planning, while post-operative assessment was done in two cases to check the accuracy of planned implants. Digital 3D planning software was reported for presurgical planning and craniofacial implants placement, fabrication of molds, designing of implants, designing of retentive attachments, and printing of silicone prostheses. Digital technology has been claimed to reduce the clinical and laboratory time; however, the equipment cost is still one of the limitations.

Ziel ist es die zeitintensive Modellherstellung mittels Gips einzusparen und die endgültige Helmschale im .stl-Format zu erzeugen. Weiter wird, mittels einer visuellen Programmierumgebung, ein Programm erzeugt um die Helmschale in einem polaren Koordinatensystem für den geplanten Hochgeschwindigkeits-Rotations-3D-Drucker auszurichten, zu slicen und die Koordinaten der einzelnen Punkte der Bahnkurven der Extruder auszugeben.
