In recent days, additive manufacturing (AM) plays a vital role in manufacturing a component compared to subtractive manufacturing. AM has a wide advantage in producing complex parts and revolutionizing logistics panorama worldwide. Many researchers compared this emerging manufacturing methodology with the conventional methodology and found that it helps in meeting the demand, designing highly complex components, and reducing wastage of materials, and there are a wide variety of AM processes. The process of making the components in full use of technology with several manufacturing applications to meet the above is studied along with the properties of AM, and subsequently, the advantages of AM over the subtractive methods are described. In this paper, the achievements in this manner with considerable gains are studied and are concluded as a paradigm shift to fulfil the AM potential.

Abstract Hybrid process chains lack structured decision-making tools to support advanced manufacturing strategies, consisting of a simulation-enhanced sequencing and planning of additive and subtractive processes. The paper sets out a method aiming at identifying an optimal process window for additive manufacturing, while considering its integration with conventional technologies, starting from part inspection as a built-in functionality, quantifying geometrical and dimensional part deviations, and triggering an effective hybrid process recipe. The method is demonstrated on a hybrid manufacturing scenario, by dynamically sequencing laser deposition (DLM) and subtraction (milling), triggered by intermediate inspection steps to ensure consistent growth of a part.

Additive manufacturing technology overcomes the limitations imposed by traditional manufacturing techniques, such as fixtures, tools, and molds, thereby enabling a high degree of design freedom for parts and attracting significant attention. Combined with subtractive manufacturing technology, additive and subtractive hybrid manufacturing (ASHM) has the potential to enhance surface quality and machining accuracy. This paper proposes a method for simulating the additive and subtractive manufacturing process, enabling accurate deformation prediction during processing. The relationship between stress distribution and thermal stress deformation of thin-walled 316L stainless steel parts prepared by Laser Metal Deposition (LMD) was investigated using linear scanning with a laser displacement sensor and finite element simulation. The changes in stress and deformation of these thin-walled parts after milling were also examined. Firstly, 316L stainless steel box-shaped thin-walled parts were fabricated using additive manufacturing, and the profile information was measured using a Micro Laser Displacement Sensor. Then, finite element software was employed to simulate the stress and deformation of the box-shaped thin-walled part during the additive manufacturing process. The experiments mentioned were conducted to validate the finite element model. Finally, based on the simulation of the box-shaped part, a simulation prediction was made for the box-shaped thin-walled parts produced by two-stage additive and subtractive manufacturing. The results show that the deformation tendency of outward twisting and expanding occurs in the additive process to the box-shaped thin-walled part, and the deformation increases gradually with the increase of the height. Meanwhile, the milling process is significant for improving the surface quality and dimensional accuracy of the additive parts. The research process and results of the thesis have laid the foundation for further research on the influence of subtractive process parameters on the surface quality of 316L stainless steel additive parts and subsequent additive and subtractive hybrid manufacturing of complex parts.

Additive manufacturing (AM), or 3D printing, is a manufacturing method where components are produced by successively adding material to the product layer by layer, unlike traditional machining where material is subtracted from a workpiece. There are advantages and disadvantages with both methods and it can be a complex problem to determine when one method is preferable to the other. The purpose of this study is to develop a decision support model (DSM) that quickly guides the end user in selecting an appropriate method with regards to production costs. Information is gathered through a literature study and interviews with people working with AM and CNC machining. The model takes into consideration material selection, size, times, quantities, geometric complexity, post-processing and environmental aspects. The DSM was formulated in Microsoft Excel. The difference in costs between each method in relation to quantity and complexity was made and compared to the literature. The AM model is verified with calculations from the Sandvik Additive Manufacturing. The margin of error is low, around two to six percent, when waste material isn’t included in the calculations. Unfortunately, verification of the CNC model hasn’t been performed due to a lack of data, which is therefore recommended as future work. The conclusion of the study is that AM will not replace any existing manufacturing method anytime soon. It is, however, a good complement to the metalworking industry, since small, complex parts with few tolerances benefits from AM. An investigation of existing solutions/services related to the study was also performed with the ambition that the DSM can complement existing solutions. It was found that while there are many services that helps companies with implementing AM through consulting, few provides any software to assist the company. Regarding the question if AM is profitable for certain products, only one software fulfilled that demand, though it didn’t provide any actual costs. The DSM therefore fills a gap among the existing services and software.
Additiv tillverkning (AM), eller 3D-printing, är en tillverkningsmetod där komponenter produceras genom att succesivt addera material till produkten lagervis, till skillnad från skärande bearbetning där material subtraheras från ett arbetsstycke. Det finns fördelar och nackdelar med respektive metod och det kan vara ett komplext problem att avgöra när den ena metoden är att föredra framför den andra. Syftet med denna studie är att utveckla en beslutstödjande modell (DSM) som hjälper användaren välja lämplig metod med avseende på produktionskostnader. Information inhämtas genom en litteraturstudie samt intervjuer med personer som arbetar med AM och skärande bearbetning. Modellen tar hänsyn till material, storlek, tider, geometrisk komplexitet, efterbearbetning och miljöeffekter. Den beslutstödjande modellen skapades i Microsoft Excel. Skillnaden i pris mellan respektive tillverkningsmetod beroende på antal och komplexitet jämfördes mot litteraturstudien. Modellen för AM verifieras med hjälp av kostnadskalkyler från Sandvik Additive Manufacturing. Felmarginalen är förhållandevis låg på cirka två till sex procent när spillmaterial inte tas hänsyn till. Tyvärr har modellen för skärande bearbetning inte verifieras på grund av en brist på data, vilket därför rekommenderas som fortsatt arbete. Slutsatsen är att AM inte kommer ersätta någon nuvarande tillverkningsmetod. Det är dock ett bra komplement till metallindustrin eftersom små, komplexa komponenter med få toleranskrav gynnas av AM. En undersökning över nuvarande tjänster relaterat till studien genomfördes med ambitionen att utreda om den beslutstödjande modellen kompletterar dessa. Resultatet av undersökningen visar att medan det finns många konsulttjänster som hjälper ett företag implementera AM så är det få som erbjuder någon form av mjukvara. Gällande frågan om AM är lönsam för vissa produkter så var det bara en mjukvara som kunde besvara den, dock utan att visa några kostnader. Den beslutstödjande modellen framtagen i denna studie fyller därmed en funktion bland nuvarande tjänster och mjukvaror.

Syftet: Utvärdera produktionstolerans av objekt som producerats genom additiv framställningsteknik (AF) för användning inom tandvård, samt att jämföra denna teknik med subtraktiv framställningsteknik (SF) genom reverse engineering.Material och metod: Tio exemplar av två olika geometriska objekt framställdes från fem olika AF maskiner och en SF maskin. Objekt A efterliknar ett inlay, medan objekt B återspeglar en modell av en fyrledsbro. Alla objekt delades in i olika mätled; X, Y och Z. Mätningarna utfördes med validerade och kalibrerade instrument. Linjära avstånd mättes med ett digitalt skjutmått och hörnradie samt vinklar mättes med ett digitalt mikroskop.Resultat: Vare sig additiv eller subtraktiv framställning uppvisade en perfekt matchning till CAD-filen med hänsyn till de parametrar som utvärderades i denna studie. Standardavvikelsen gällande linjära mätningar för subtraktiv framställning uppvisade konsekventa resultat i alla led, med undantag för X- och Y-led för objektet A och i Y-led för objekt B. Samtliga additiva tillverkningsgrupper hade en konsekvent standardavvikelse i X- och Y-led, men inte i Z-led. Med avseende på hörnradiemätningar, hade SF gruppen i överlag bättre produktionsnoggrannhet för både objekt A och B medan AM grupperna var mindre noggranna.Konklusion: Med hänsyn till begränsningarna med denna in vitro studie, stödjer resultat hypotesen, med hänsyn till att AF hade en bättre förmåga att återskapa komplexa och små geometrier jämfört med SF. Samtidigt identifierades en bättre reproducerbarhet hos SF gällande enkla geometrier och linjära avstånd. Vidare studier krävs för att bekräfta dessa resultat.
Purpose: To evaluate the production tolerance of objects produced by additive manufacturing systems (AM) for usage in dentistry and to compare with subtractive manufacturing system (SM) through reverse engineering. Materials and methods: Ten specimens of two geometrical objects were produced by five different AM machines and one SM machine. Object A mimics an inlay-shaped object, meanwhile object B reflects a four-unit bridge model. All the objects were divided into different measuring-axis; X, Y and Z. Measurements were performed with validated and calibrated equipment. Linear distances were measured with a digital calliper while corner radius and angle were measured with a digital microscope. Results: None of the additive manufacturing or subtractive manufacturing groups presented a perfect match to the CAD-file regarding all parameters included in present study. Considering linear measurements, the standard deviation for subtractive manufacturing group were consistent in all axis, except for X- and Y-axis in object A and Y-axis for object B. Meanwhile additive manufacturing groups had a consistent standard deviation in X- and Y- axis but not in Z-axis. Regarding corner radius measurements, SM group overall had the best accuracy for both object A and B comparing to AM groups. Conclusion: Within the limitations of this in vitro study, results support the hypothesis, considering AM had preferable capability to re-create complex and small geometry compare to SM. Meanwhile, SM were superior producing simple geometry and linear distances. Further studies are required to confirm these results.

La fabrication additive est en pleine expansion et suscite un intérêt grandissant pour l'industrie, la recherche scientifique et le grand public. Les procédés additifs ont permis des ouvertures pour fabriquer des structures à géométrie complexe par rapport aux fabrications classiques. En revanche, le comportement mécanique des fabrications additives en réponse aux chargements est peu exploré. En particulier la caractérisation mécanique de ces fabrications reste un challenge et se limite souvent à des champs d'investigations pseudo-statiques par des moyens de tests mécaniques classiques tels que des essais de traction. Ce travail de thèse tente donc d'apporter une contribution à la caractérisation mécanique dynamique des fabrications additives sur un champ comparatif avec les fabrications soustractives. Cette contribution repose sur l'utilisation de méthodes modales en réponse à des stimuli « Low Velocity » appliqués au marteau de choc et sur une méthode dynamique « High Velocity » en étudiant le comportement à l’impact de plaques réalisées par procédés additifs (SLM) et soustractifs
Additive manufacturing is rapidly expanding and attracting increasing interest from industry, scientific research and the general public. Additive processes have opened up opportunities for producing structures with complex geometries compared to traditional manufacturing. However, the mechanical behavior of additive fabrications under loading conditions is not extensively explored. In particular, the mechanical characterization of these fabrications remains a challenge and often limits itself to pseudo-static investigation fields through conventional mechanical testing methods such as tensile tests. This doctoral thesis aims to contribute to the dynamic mechanical characterization of additive manufacturing on a comparative scale with subtractive manufacturing. This contribution is based on the use of modal methods in response to 'Low Velocity' stimuli applied by an impact hammer, and on a 'High Velocity' dynamic method studying the impact behavior of plates produced by additive (SLM) and subtractive processes

MOTIVATION In the simplest form, a pencil mark on a page is removed by a traditional rubber eraser. However, the marks are often never fully removed, and the paper thins with each attempt to rub out an old idea. But how does one erase a chair? A pilaster? A room? A building?... More importantly, how does the subtractive act of erasing become an additive one? The historical fabric of a building is important; it is also imperative that it does not remain stagnant. Erasing is an opportunity to design an interior environment that both acknowledges the traces of the pencil marks and the eraser. It is an opportunity to learn from historic design strategies and thoughtfully transition into the present to create a living, breathing palimpsest (Plesch, 2015). PROBLEM Current preservation policies and landmarking tactics arguably contradict preservationists’ claims of promoting environmental, economic, and social growth within communities by exempting historical buildings from complying with codes and regulations which consequently use property that could be more sustainably employed. Historical preservation is largely based in social constructs; therefore, present policies should be reflective of societal changes. At times, the act of preserving often removes these buildings from the possibility of a relevant and functional future by attempting to keep them wedged within historical restraints (Avrami, 2016). METHOD Research of precedent incidents of erasure with applications to concepts involving historical preservation and restoration in the fields interior design and architecture will influence the design approach. These precedent studies will include works by Carlo Scarpa, Peter Zumthor, and David Chipperfield. To supplement these studies, other artistic disciplines and artists, including Robert Rauschenberg, will be researched to holistically comprehend approaches to the concept of erasing. The execution of explorations of erasing different objects and media to better understand the process of erasure will also be imperative. These experimentations will include the strategic erasing of pencil sketches and common objects to investigate how to best represent an object that has been erased. PRELIMINARY RESULTS The approach to erasing the historical fabric of a building is largely dependent on the building itself. This is evident in Scarpa’s attention to the physical and metaphorical joinery of new and existing structures in his design of Palazzo Abatellis, Zumthor’s weaving of old and new brickwork at Kolumba, and Chipperfield’s use of exposed ruins in his design strategy for the Neues Museum (McCarter, 2013; Carrington, 2008; RYKWERT, 2009). The process of erasure within the realm of preservation is a constant and demonstrates how the act of erasing allows opportunities for the existence of something new (Katz, 2006). CONCLUSION Choosing to re-program and systematically erase a section of a historically significant but outdated medical tower as a collective art studio space would introduce the opportunity to design an “erased space “as an environment for post-graduate art students to produce creative work. This space would strengthen the growing bond between a school of the arts and a historic medical school while contributing to the culture of the surrounding neighborhoods and contribute to the rich tradition of art within the city.

The supply chain is changing speedily and on a continuous basis to keep up with the rapid changes in the market, which are summarized as increased competition, changes in traditional customer bases, and changes in customers’ expectations. Thus, companies have to change their way of manufacturing final products in order to customize and expedite the delivery of products to customers. Additive manufacturing, the new production system, effectively and efficiently increases the capability of personalization during the manufacturing process. This consequently increases customer’s satisfaction and company’s profitability. In other words, additive manufacturing has become one of the most important technologies in the manufacturing field. Full implementation of additive manufacturing will change many well-known management practices in the production sector. Theoretical development in the field of additive manufacturing in regards to its impact on supply chain management is rare. There is no fully applied approach in the literature that is focused on managing the supply chain when additive manufacturing is applied. While additive manufacturing is believed to revolutionize and enhance traditional manufacturing, there is no comprehensive toolset developed in the manufacturing field that evaluates the impact of additive manufacturing and determines the best production method that suits the applied supply chain strategy. A significant portion of the existing supply chain methods and frameworks were adopted in this study to examine the implementation of additive manufacturing in supply chain management. The aim of this study is to develop a framework to explain when additive manufacturing “3D printing” impacts supply chain management efficiently. To build the framework, interviews with some companies that already use additive manufacturing in their production system have been carried out. Next, an online survey and two case studies evaluated the framework and validated the results of the final version of the framework. The conceptual framework shows the relationship among supply chain strategies, manufacturing strategy and manufacturing systems. The developed framework shows not only the ability of additive manufacturing to change and re-shape supply chains, but its impact as an alternative manufacturing technique on supply chain strategies. This framework helps managers select more effective production methods based on certain production variables, including product’s type, components’ value, and customization level.

Aus der Einführung: "Stehen wir am Rande einer bio-nanotechnologischen getriebenen Revolution, die unsere Art zu leben, zu arbeiten und miteinander umzugehen grundlegend verändern wird? Welchem gesellschaftspolitischen, wirtschaftlichen und technologischen Wandel haben wir uns zu stellen? Langfristige Entwicklungszyklen (Kondratieff, Schumpeter) führen zur nachhaltigen Weiterentwicklung der Zivilisation. Mittelfristige Entwicklungen wie die Trends Globalisierung, Urbanisierung, Digitalisierung (Miniaturisierung) und Humanisierung (Individualisierung), die immer stärker unser Umfeld und Handeln beeinflussen führen zu ganzheitlichen, weltumspannenden Grundtendenzen der gesellschaftlichen Weiterentwicklung. Die technologischen "Enabler" Computing, Biotechnology, Artifical Intelligence, Robotik, Nanotechnology, Additive Manufacturing und Design Thinking wirken beschleunigend auf die gesellschaftlichen Entwicklungen ein. Die technologischen Möglichkeiten beschleunigen sowohl gesellschaftspolitische Zyklen und zivilisatorische Anpassungen. Durch rasanten technologischen, wissenschaftlichen Fortschritt, zunehmende Globalisierungswirkungen, beschleunigte Urbanisierung und aber auch politischer Interferenzen sind die Veränderungsparameter eines dynamischen Geschäftsumfelds immer schnellere Transformationen ausgesetzt. Alle diese Richtungen zeigen das unsere gesellschaftliche Entwicklung inzwischen stark durch die Technik getrieben ist. Ob dies auch heißt, dass wir den Punkt der Singularität (Kurzweil) absehbar erreichen ist dennoch noch offen. ..."

Prior research has shown that powder bed fusion additive manufacturing (AM) can be used to make functional, end-use components from powdered metallic alloys, such as Inconel® 718 super alloy. However, these end-use products are often based on designs developed for more traditional subtractive manufacturing processes without taking advantage of the unique design freedoms afforded by AM. In this paper, we present a case study involving the redesign of NASA’s existing “Pencil” thruster used for spacecraft attitude control. The initial “Pencil” thruster was designed for, and manufactured using, traditional subtractive methods. The main focus in this paper is to (a) review the Design for Additive Manufacturing (DfAM) concepts and considerations used in redesigning the thruster and (b) compare it with a parallel development effort redesigning the original thruster to be manufactured more effectively using subtractive processes. The results from this study show how developing end-use AM components using DfAM guidelines can significantly reduce manufacturing time and costs while introducing new and novel design geometries.

Abstract While advances in metals additive manufacturing continue to make additive a viable option in more scenarios, these processes are generally slower and more expensive than subtractive methods, like machining. The combination of both additive and subtractive, often called hybrid manufacturing, can be used to get the benefits of both processes, while reducing cost. However, dividing a part into the most cost effective additive and subtractive features is often time-consuming and non-intuitive. In this paper, we present a new approach that optimizes the type, size, and position of a substrate within a part. The resulting hybrid manufacturing configuration enables engineers to reach the most cost-effective compromise between additive and machining. A fully implemented method has been developed and tested on several realistic engineering parts. The results are intuitively useful and push the state-of-the-art forward in generating hybrid manufacturing process plans.

Engineering students are often unaware of manufacturing challenges introduced during the design process. Students tend to design parts that are either very difficult or impossible to manufacture because they are unaware of the intricacies and limitations of the manufacturing processes available. Design for manufacturability (DFM) education must be improved to help address this issue. This work discusses a vision for the implementation of a rapid method for facilitating DFM education in terms of subtractive and additive manufacturing processes. The goal is to teach students about how their designs impact the ease and cost of manufacturing, in addition to giving them knowledge and confidence to move fluidly between additive and subtractive manufacturing mindsets. For subtractive manufacturing, this is accomplished through a high-performance-computing accelerated and parallelized trajectory planning software package that enables students to visualize the subtractive manufacturability of the parts they design as rapidly as they get feedback when using additive manufacturing processes. Implementation of the subtractive manufacturability analysis tool in a sophomore-level design class is presented, along with the assessment of the students’ conceptual manufacturing-related understanding.

This article addresses the generation and use of manufacturability constraints for design under hybrid additive/subtractive processes. A method for discovering the natural constraints inherent in both additive and subtractive processes is developed; once identified, these guidelines can be converted into mathematical manufacturability constraints to be used in the formulation of design problems. This ability may prove to be useful by enhancing the practicality of designs under realistic hybrid manufacturing conditions, and supporting better integration of classic design-for-manufacturability principles with design and solution methods. A trade-off between design manufacturability and elegance has been noted by many scholars. It is posited that using realistic manufacturing conditions to drive design generation may help manage this trade-off more effectively, focusing exploration efforts on designs that satisfy more comprehensive manufacturability considerations. While this study focuses on two-step AM-SM hybrid processes, the technique extends to other processes, including single-process fabrication. Two case studies are presented here to demonstrate the new constraint generation concept, including formulation of shape and topology optimization problems, comparison of results, and the physical fabrication of hybrid-manufactured products. Ongoing work is aimed at rigorous comparison between candidate constraint generation strategies and the properties of the constraint mapping.
