  • Press Release As PDF: Voestalpine Company Uddeholms AB Is
    voestalpine AG PRESS RELEASE June 28, 2018 voestalpine company Uddeholms AB is celebrating 350 years of innovation at the site in Hagfors, Sweden Founded in 1668 as a family-run iron mill in Värmland, southern Sweden, today Uddeholms AB is a global market leader in the production of special steels for toolmaking. With sales sites and partners in over 90 countries, the company supplies the global automotive, mechanical engineering, and consumer goods industries with sophisticated steel grades from Hagfors. Uddeholms AB has a workforce of 900 employees at its headquarters and generated revenue of EUR 305 million in the past business year. Over the past ten years more than EUR 130 million has been invested at the site—intensive development of digitalization technologies and the production of metal powder for 3D printing will secure the future of this site with its long history. Over a period of three and a half centuries, the former family-run company in Hagfors has advanced to become a global player in tool steel. In 1991 Uddeholms AB and Austrian-based special steel manufacturer Böhler combined to form Böhler-Uddeholm AG which was subsequently listed on the Vienna Stock Exchange. The group was taken over by voestalpine in 2007 and is now part of the Group’s High Performance Metals Division. “With its know-how in developing and manufacturing high-tech steels, and its global customer network, Uddeholms AB has played a significant role in making our Group more specialized and international over the past decade. To mark the occasion of today’s anniversary, my particular thanks go to the employees in Hagfors.

The difference is in the use and scalability, not in the technology itself: Rapid Prototyping: used to generate non-structural and non-functional demo pieces or batch-of-one components for proof of concept. Additive Manufacturing: used as a real, scalable manufacturing process, to generate fully functional final components in high-tech materials for low-batch, high-value manufacturing. 4 Why is Additive Manufacturing the Next Frontier?

    E. Ceron et al.: Testing new tribo-systems for sheet metal forming of advanced high strength steels and stainless steels TESTING NEW TRIBO-SYSTEMS FOR SHEET METAL FORMING OF ADVANCED HIGH STRENGTH STEELS AND STAINLESS STEELSI E. CERON1, N. BAY2*, 1Grundfos A/S, Poul Due Jensens Vej 7, 8850 Bjerringbro, Denmark. 2Dep. of Mech. Eng., Technical University of Denmark, Produktionstorvet 425, 2800 Kgs. Lyngby, Denmark. ABSTRACT Testing of new tribo-systems in sheet metal forming has become an important issue due to new legislation, which forces industry to replace current, hazardous lubricants. The present paper summarizes the work done in a recent PhD project at the Technical University of Denmark on the development of a methodology for off-line testing of new tribo-systems for advanced high strength steels and stainless steels. The methodology is presented and applied to an industrial case, where different tribo-systems are tested. A universal sheet tribotester has been developed, which can run automatically repetitive Bending Under Tension tests. The overall results show that the methodology ensures satisfactory agreement between laboratory tests and production tests, although disagreement can occur, if tribological conditions are not the same in the two cases. Keywords: Sheet metal forming, off-line testing of tribo-systems, galling. *Corresponding author: Niels Bay ([email protected]). INTRODUCTION achieve, and custom built laboratory tests have been developed for the simulation of New, stricter regulations on handling of deep drawing and ironing operations [4].

  • 3D Printing: Hype Or Game Changer?
    3D printing: hype or game changer? A Global EY Report 2019 What is additive manufacturing? Additive manufacturing (AM), commonly known as 3D printing (3DP), is a digital manufacturing process that involves slicing three-dimensional digital designs into layers and then producing additively, layer by layer, using AM systems and various materials. Table of contents 04 Foreword 05 Key findings 06 About this study 08 3DP moves into the operational mainstream 14 From the lab to the shop window: AM serial production takes off 22 Choosing the right 3DP operating model 28 Growing up with AM 32 How AM can give businesses a competitive edge 36 The evolution of 3DP technologies and materials 40 What holds companies back from adopting 3DP? 44 AM trends, developments and challenges 50 M&A activity in the 3DP market 58 What’s next for AM? 60 How EY teams support companies on their 3DP journey 63 Authors 3D printing: hype or game changer? A Global EY Report 2019 | 3 Foreword In the three years since EY published first 3DP report, additive manufacturing (AM) has grown up. The technology has attracted such exposure that almost two- thirds (65%) of the businesses we surveyed this year have now tried the technology — up from 24% in 2016. Any early skepticism that predictions of 3DP’s transformative potential were just hype have been laid to rest. AM has joined the armory of production technologies, with 18% of companies already using it to make end- use products for customers and consumers. This means that the crucial “early majority” — whose buy-in is essential to the success of any new technology — have been won over.

  • History of Additive Manufacturing
    Wohlers Report 2012 State of the Industry History of additive This 26-page document is a part of Wohlers Report 2012 and was created for its readers. The document chronicles the history of additive manufacturing manufacturing (AM) and 3D printing, beginning with the initial commercialization of by Terry Wohlers and Tim Gornet stereolithography in 1987 to May 2011. Developments from May 2011 to May 2012 are available in the complete 287-page version of the report. An analysis of AM, from the earliest inventions in the 1960s to the 1990s, is included in the final several pages of this document. Additive manufacturing first emerged in 1987 with stereolithography (SL) from 3D Systems, a process that solidifies thin layers of ultraviolet (UV) light- sensitive liquid polymer using a laser. The SLA-1, the first commercially available AM system in the world, was the precursor of the once popular SLA 250 machine. (SLA stands for StereoLithography Apparatus.) The Viper SLA product from 3D Systems replaced the SLA 250 many years ago. In 1988, 3D Systems and Ciba-Geigy partnered in SL materials development and commercialized the first-generation acrylate resins. DuPont’s Somos stereolithography machine and materials were developed the same year. Loctite also entered the SL resin business in the late 1980s, but remained in the industry only until 1993. After 3D Systems commercialized SL in the U.S., Japan’s NTT Data CMET and Sony/D-MEC commercialized versions of stereolithography in 1988 and 1989, respectively. NTT Data CMET (now a part of Teijin Seiki, a subsidiary of Nabtesco) called its system Solid Object Ultraviolet Plotter (SOUP), while Sony/D-MEC (now D-MEC) called its product Solid Creation System (SCS).
