Business Models for Additive Manufacturing: Exploring Digital Technologies, Consumer Roles, and Supply Chains2015 •
Digital fabrication — including additive manufacturing (AM), rapid prototyping and 3D printing — has the potential to revolutionize the way in which products are produced and delivered to the customer. Therefore, it challenges companies to reinvent their business model — describing the logic of creating and capturing value. In this paper, we explore the implications that AM technologies have for manufacturing systems in the new business models that they enable. In particular, we consider how a consumer goods manufacturer can organize the operations of a more open business model when moving from a manufacturer-centric to a consumer-centric value logic. A major shift includes a move from centralized to decentralized supply chains, where consumer goods manufacturers can implement a “hybrid” approach with a focus on localization and accessibility or develop a fully personalized model where the consumer effectively takes over the productive activities of the manufacturer. We discuss some...

This study is mainly focussed to fully understand the mechanical properties and characteristics of the parts manufactured using additive manufacturing. It is very important to understand the mechanical properties of products manufactured through various additive manufacturing processes like Stereolithography (SLA), Selective Laser Sintering (SLS), and Fused Deposition Modeling (FDM) and Polyjet. In this project the mechanical properties such as Dimensional Accuracy, Tensile property and Shore Hardness of components manufactured by various additive manufacturing techniques as per ASTM D638-10 type iv standard are evaluated. Each additive manufacturing process and its process parameters are studied in detail along with comparison of mechanical properties of the final components.
At present handcrafting is still common in surgery and dentistry. The majority of patient specific implants are handmade during surgery and oral appliances are handmade by a dental technician in a dental laboratory. Surgical procedures are usually designed according to medical imaging, but during the surgery, plans are often changed due to issues that were not detectable from the two dimensional images. By using the modern digital technology it is possible to reduce or completely avoid manual work phases, and thus achieve remarkable advantages related to accuracy and speed. Additive manufacturing is a material adding fabrication process, which suits for manufacturing objects with complex geometric shapes for either one piece or small series production. The parts are produced automatically according to a digital 3D model. By digitalizing the medical processes of additive manufacturing can be easily and rapidly performed. Therefore, it is a suitable manufacturing method in both surgery and dentistry. This research concentrated on medical models and patient specific implants made by additive manufacturing, as well as oral appliances used in dentistry. The subjects included (1) medical 3D modeling and design, (2) applying various additive manufacturing technologies and (3) estimating the usability and dimensional accuracy of these processes. As a result a patient specific orbital floor implant and different oral appliances were produced using additive manufacturing and digital design. In addition the effects of different additive manufacturing methods for accuracy of medical models were studied. The results showed that additive manufacturing can be effectively utilized in surgery and dentistry, and patients' treatment results may improve when using the above methods.

The aim of our study was to analyze the precision of fused-deposition modeling (FDM), polyjet technology (PJ), stereolithography (SLA) and selective laser sintering (SLS) and to evaluate some interesting indications of these methods in clinical practice. Forty upper dental arches were scanned using a 3Shape Trios 3R optical scanner system and 3D models were made. An Atos II 400 optical 3D scanner was used for calculating the coordinates of points by optical triangulation, photogrammetry and fringe projection. Each model was scanned from a minimum of 56 positions to evaluate global coordinates. Surface morphology was evaluated with an Alpha Step IQ profilometer and a JSM 5510 LV scanning electron microscope. From the measurements in cross-sections it was evident that the deviation shifted by approximately 0.1 mm. The smoothest and most homogeneous sample was SLA. SLS and SLA samples showed the most similar results in comparison of perpendicular directions (homogeneity). FDM and PJ ma...

Surface roughness of as-printed polymers: a comprehensive reviewSurface roughness is gaining increasing recognition in the processing design methods of additive manufacturing (AM) due to its role in many critical applications. This impact extends not only to various AM product manufacturing but also to indirect applications, such as molding and casting. This review article discusses the role of processing on the surface roughness of AM-printed polymers with limited post-processing by summarizing recent advances. This review offers a benchmark for surface quality improvement of AM processes, considering the surface roughness of polymeric parts. For this purpose, it lists and analyzes the key processes and various printing parameters used to monitor and adjust surface roughness under given constraints. Four AM techniques for manufacturing polymeric parts are compared: fused filament fabrication (FFF), selective laser sintering (SLS), vat photopolymerization (VPP), and material jetting (MJT). A review and discussion of recent studies are presented,...
