<p>Due to the economic advantage of mass manufacturing technology humans have designed a world of products built for the average body size and shape. This conformity of diverse body shapes to fixed 3 dimensional forms raises the question for this research; how can 3D scanning and additive manufacturing (AM) create a personal fit between an individual’s body and a product?  This question challenges a tool driven standardised approach to manufacture by exploring the interface between a person and a mass produced product, in this case a motorcycle rider and a motorcycle. By taking advantage of digital data and the tool-less build process of 3D printing, every object produced can be different, tailoring it to the customer’s individual aesthetic or physical fit.  This investigation into the space between the motorcycle and the human has produced a custom 3D printed seat designed for and inspired by the unique physicality of the individual rider. The following methods are employed. 3D scanning is used to obtain the geometry of the human form and motorcycle, 3D modelling and 3D printing to generate and evaluate ideas and concepts, and a pressure measurement system to evaluate the riders comfort and fit.  This new relationship between body and object, rarely seen in mass produced products, questions the way we design and make products with consideration towards digital personalisation and manufacturing efficiency.</p>

3D printing has seen a recent massive diffusion for several applications, not least the field of Cultural Heritage. Being used for different purposes, such as study, analysis, conservation or access in museum exhibitions, 3D printed replicas need to undergo a process of validation also in terms of metrical precision and accuracy.<br> The Laboratory of Photogrammetry of Iuav University of Venice has started several collaborations with Italian museum institutions firstly for the digital acquisition and then for the physical reproduction of objects of historical and artistic interest. The aim of the research is to analyse the metric characteristics of the printed model in relation to the original data, and to optimize the process that from the survey leads to the physical representation of an object. In fact, this could be acquired through different methodologies that have different precisions (multi-image photogrammetry, TOF laser scanner, triangulation based laser scanner), and it always involves a long processing phase. It should not be forgotten that the digital data have to undergo a series of simplifications, which, on one hand, eliminate the noise introduced by the acquisition process, but on the other one, they can lead to discrepancies between the physical copy and the original geometry. In this paper we will show the results obtained on a small archaeological find that was acquired and reproduced for a museum exhibition intended for blind and partially sighted people.

<p>This research is focused towards the use of large-scale FDM 3D printing within the automotive industry, specifically to design a bespoke habitable sleeping environment attached to a Range Rover Sport. 3D printing has risen as a viable form of manufacturing in comparison with conventional methods. Allowing the designer to capitalise on digital data, enabling specific tailored designs to any vehicle model. This thesis asks the question “Can design use the properties of digital vehicle data in conjunction with large-scale FDM 3D printing to sustainably produce bespoke habitable sleeping environments for an automotive context?” Further to this, FDM 3D printing at a large-scale has so far not been explored extensively within the automotive industry.  FDM 3D printing is an emerging technology that possesses the ability to revolutionise the automotive industry, through expansion of functionality, customisation and aesthetic that is currently limited by traditional manufacturing methods. Presently, vehicle models are digitally mapped, creating an opportunity for customisation and automatic adaption through computer aided drawing (CAD). This thesis takes advantage of the digitisation of the automotive industry through 3D modelling and renders as a design and development tool.   This project explored a variety of methods to demonstrate a vision of a 3D printed habitable sleeping environment. The primary methodologies employed in this research project are Research for Design (RfD) and Research through Design (RtD). These methodologies work in conjunction to combine design theory and practice as a genuine method of inquiry. The combination of theory and design practice has ensued in the concepts being analysed, reflected and discussed according to a reflective analysis design approach. The design solution resulted in an innovative and luxury bespoke habitable sleeping space to be FDM 3D printed. Through the use of digitisation, the sleeping capsule was cohesively tailored to the unique design language of the Range Rover Sport. This thesis resulted in various final outputs including a 1:1 digital model, high quality renders, accompanied by small scale prototypes, photographs and sketch models.</p>

Introduction: Simulation-based training has become a popular tool for chest tube training, but existing training modalities face inherent limitations. Cadaveric and animal models are limited by access and cost, while commercial models are often too costly for widespread use. Hence, medical educators seek a new modality for simulation-based instruction. 3D printing has seen growing applications in medicine, owing to its advantages in recreating anatomical detail using readily available medical images. Methods: Anonymised computer tomography data of a patient’s thorax was processed using modelling software to create a printable model. Compared to a previous study, 3D printing was applied extensively to this task trainer. A mixture of fused deposition modelling and material jetting technology allowed us to introduce superior haptics while keeping costs low. Given material limitations, the chest wall thickness was reduced to preserve the ease of incision and dissection. Results: The complete thoracostomy task trainer costs approximately SGD$130 (or USD$97), which is significantly cheaper compared to the average commercial task trainer. It requires approximately 118 hours of print time. The complete task trainer simulates the consistencies of ribs, intercostal muscles and skin. Conclusion: By utilising multiple 3D printing technologies, this paper aims to outline an improved methodology to produce a 3D printed chest tube simulator. An accurate evaluation can only be carried out after we improve on the anatomical fidelity of this prototype. A 3D printed task trainer has great potential to provide sustainable simulation-based education in the future.

Abstract Background Rhinoplasty is a complex procedure that requires meticulous planning and precise execution. Plastic surgeons involved in teaching residents must balance a trainee’s hands-on experience while ensuring appropriate execution of difficult maneuvers. Surgical simulation, a field of growing importance with the shift towards competency-based education, may aid in trainee skill development. Through the concept of deliberate practice, the authors looked to explore the utility and economics of 3-dimensional (3D) printing technology to develop a step-specific rhinoplasty simulator. Objectives The main objective of this study was to address rhinoplasty skills previously identified as “learning areas of weakness” and develop a low-cost, step-specific simulator to help rhinoplasty teaching. Methods A patient’s facial bones, upper and lower lateral cartilages, and septum were segmented from a computed tomography scan and rendered in 3D format. This was 3D printed utilizing Ultimaker Polylactic filament with a polyvinyl acetate dissolvable support for bone, a mixture of Rigur 450 and Tango plus polyjet material for cartilage, and Smooth-On Dragon Skin for skin. Results A modular simulator was developed with 3 separate, interchangeable components with a perfect fit design. The simulator allowed for deliberate practice of the 5 rhinoplasty learning areas of weakness, with a maximal recurring cost of $75 CAD. Conclusions Through the employment of 3D printing, a low-cost, maneuver-specific rhinoplasty simulator reinforcing deliberate practice was developed. This concept of simulation-based deliberate practice may be of increasing interest when considering the implementation of competency-based curricular standards in plastic surgery education.

The postcuring process is essential for 3-dimensional (3D) printing of photopolymer-based dental prostheses. However, the deformation of prostheses resulting from the postcuring process has not been fully investigated. The purpose of this study was to evaluate the effects of different postcuring methods on the fit and dimensional accuracy of 3D-printed full-arch polymeric fixed prostheses. A study stone model with four prosthetic implant abutments was prepared. A full-arch fixed dental prosthesis was designed, and the design was transferred to dental computer-aided manufacturing (CAM) software in which supports were designed to the surface of the prosthesis design for 3D printing. Using a biocompatible photopolymer and a stereolithography apparatus 3D printer, polymeric prostheses were produced ( N = 21 ). In postcuring, the printed prostheses were polymerized in three different ways: the prosthesis alone, the prosthesis with supports, or the prosthesis on a stone model. Geometric accuracy of 3D-printed prostheses, marginal gap, internal gap, and intermolar distance was evaluated using microscopy and digital techniques. Kruskal-Wallis and Mann-Whitney U tests with Bonferroni correction were used for the comparison of results among groups ( α = 0.05 ). In general, the mean marginal and internal gaps of cured prostheses were the smallest when the printed prostheses were cured with seating on the stone model ( P < 0.05 ). With regard to the adaptation accuracy, the presence of supports during the postcuring process did not make a significant difference. Error in the intermolar distance was significantly smaller in the model seating condition than in the other conditions ( P < 0.001 ). Seating 3D-printed prosthesis on the stone model reduces adverse deformation in the postcuring process, thereby enabling the fabrication of prostheses with favorable adaptation.

In cultural heritage study of 3D modeling has become a very useful process to obtain indispensable data for documentation and visualization. 3D scanning and 3D printing suggest a vital solution in preserving and sustaining traditional folk costumes. 3D scanning and 3D digitizing is defined as the process of using metrological methods to ascertain the size and shape of a scanned object, which may often involve an optical device that rotates around the desired scanned model. In digital preservation, especially for three dimensional physical artifacts in various crafts, the geometric shape of an object is most important. The aim of this paper is to show 3D scanning technology that produces a high-precision digital reference document to provide virtual model for replication, and makes possible easy mass distribution of digital data. We also experimented with 3d Additive manufacturing or 3D printing to show a way to actualize digital forms of folk accessories for the experimental manufacturing and to show a way how to preserve nowadays the original object. The work includes scanning, modeling, and printing of waist coat and of coin handicrafts. Experiments will be carried out on 3d scanning, 3d modeling software, reconstruction and fabrication -rapid prototyping.
