AM in India

September 15, 2019

Filed under: 3D printing,additive manufacturing,event — Terry Wohlers @ 18:11

For years, additive manufacturing and 3D printing have been put to work in India for concept modeling, design validation, prototyping, and some tooling. Organizations in the U.S., Germany, and other countries are pushing hard to adopt AM for production applications, with India showing similar interest. AM is the subject of a session at the 11th NASSCOM Design & Engineering Summit on September 26-27, 2019 in Bangalore. I’m excited about participating in this important event.

In 2018, AM in India was dominated by growing interest in metal AM systems, according to Mukesh Agarwala, managing director of 3D Product Development (3DPD) of Bangalore, India’s largest AM service provider. Agarwala contributes a summary on AM in India for publication in the annual Wohlers Report. He said that Indian organizations in the oil/gas and IT sectors are currently evaluating ways in which AM might help their businesses.

AM machines, materials, and services in India in 2018 were an estimated $100+ million, according to Agarwala. While this is not insignificant, it represents only about 1% of the global AM total of $9.8 billion, according to Wohlers Report 2019. Even so, the opportunity in India is vast. As more educational, research, and corporate entities understand the many benefits and competitive advantages that AM offers, adoption will increase to become significant.

Note: Ray Huff, associate engineer at Wohlers Associates, authored the following.

Two weeks ago, Wohlers Associates attended the 30th annual Solid Freeform Fabrication (SFF) Symposium in Austin, Texas. The event brought together more than 700 attendees from 25 countries to present and discuss research on additive manufacturing (AM). Dave Bourell, PhD, of the University of Texas at Austin opened the event by recalling the nascent stages of AM 30 years ago and the many contributors to the technology since that time.

Terry Wohlers, introduced as the “Indiana Jones” of AM, continued this discussion in a keynote presentation by highlighting key developments since 1987. He then called Bourell back to the stage to name him an honorary associate consultant of Wohlers Associates. Bourell is only the third in the company’s 32-year history to be given this distinction. His contribution to the research community and AM as a whole is far-reaching and inspiring. Bourell continues to serve as the principal organizer of the SFF Symposium. He is also one of three associate authors of Wohlers Report 2019.

Bourell was given a special Wohlers Associates lapel pin, which is shown in the previous image. The pin was 3D-printed in titanium by the Centre for Rapid Prototyping and Manufacturing at Central University of Technology in Bloemfontein, South Africa.

Martin and Short

Filed under: entertainment,event,review — Terry Wohlers @ 18:00

Steve Martin and Martin Short were in northern Colorado on Friday for a two-hour show filled with comedy and music. Martin and Short are among my favorite comedians. They have been in many movies and television programs such as the Three Amigos and Saturday Night Live. Martin also starred in Father of the Bride, The Jerk, Planes, Trains, and Automobiles, Parenthood, The Pink Panther, and many others.

The evening began with clips from classic movies and SNL skits to warm up the audience at Budweiser Event Center near Loveland. Martin and Short then appeared to a warm applause and launched into hilarious stories about friends, family, celebrities, and themselves. Throughout the evening, the two took many friendly jabs at one another. They had the audience laughing and in tears. I’m glad my wife and I, along with friends, attended the show.

In the coming weeks and months, Martin, 73, and Short, 69, will perform in other parts of the U.S., as well as in Canada and New Zealand. If you like good, live comedy from two of the very best, book an evening with them. You won’t regret it.

World Economic Forum

Filed under: 3D printing,additive manufacturing,event,future — Terry Wohlers @ 10:49

I attended a first-ever 3D printing and additive manufacturing event organized and hosted by the World Economic Forum’s Centre for the Fourth Industrial Revolution in San Francisco. The June 3, 2019 workshop, titled 3D Printing and Trade Logistics: Impact on Global Value Chains, involved 18 invited company executives, government officials, and others from many countries.

The World Economic Forum is an independent and non-profit international organization that engages political, business, and other leaders to shape global, regional, and industrial agendas. It serves as a platform to bring together public and private sector stakeholders to tackle global issues. In this context, the workshop was organized in two phases. The first explored significant issues that may be raised by the proliferation of 3D printing, followed by ways in which they might be addressed with many working together.

Venkataraman “Sundar” Sundareswaran of Mitsubishi Chemical Holdings Corp. did a fine job at organizing the workshop. He is currently serving as a fellow at the World Economic Forum to bring 3D printing to the forefront. The group of 18 participants split into three workgroups on three separate occasions to identify and prioritize major issues, followed by the generation of ideas for addressing them.

“Workforce displacement and skill gaps” was identified as the top issue. University and industry training, coupled with retraining programs and government incentives, were named as likely solutions. “Governance of IP, legal issues, cyber, trade, and customs” was ranked as the second biggest issue. Among the possible solutions: national strategies, new laws, technology, and self-regulation. “Supply chain disruption” was determined as the third most important issue. The group cited new taxation models from government and standards development, principally by industry, as ways to address it.

The next challenge and opportunity for the World Economic Forum is to tackle these issues. A good foundation has been set. I’m looking forward to staying engaged and helping however we can to advance the development and adoption of 3D printing technology worldwide.

RAPDASA and Formnext

Filed under: 3D printing,additive manufacturing,education,event — Terry Wohlers @ 17:11

I attended last week’s 19th annual conference and exhibition of the Rapid Product Development Association of South Africa (RAPDASA) in Johannesburg. About 220 people attended from several countries. The RAPDASA organization does a fantastic job with the event year after year, and this year was no exception. (I’ve attended all 19 of them.) Thanks to the fine people at Resolution Circle and the University of Johannesburg for hosting the event, and many others who worked hard to make it a success. Pictured in the following image are Ian van Zyl and Deon de Beer, both of Central University of Technology (CUT), and Amelia Du Toit of Lonmin, and me. CUT and Lonmin are a part of an interesting project named PlatForum, which involves the development and 3D printing of parts in platinum.

This week was Formnext, a trade fair in Frankfurt, Germany, which included much of the best in additive manufacturing products and services worldwide. An estimated 26,919 people and 632 exhibitors filled two large exhibition halls at Messe Frankfurt. AM machines and parts dominated, but design software products for AM and post-processing machinery were also in abundance at this year’s fourth annual event. The development of end-to-end process chains has never been more important and it was evident. The following image shows the XJet exhibit—one of the many impressive displays at Formnext.

On November 14 at Formnext, a half-day Additive Manufacturing Standards Forum was held. It was initiated by America Makes and the American National Standards Institute (ANSI) with support from the U.S. Department of Commerce’s U.S. Commercial Service in Düsseldorf. The purpose of the half-day session was to bring together key stakeholders and others to provide an update, answer questions, and discuss AM standards development worldwide. I had the privilege of moderating the session. The following shows the organizations that supported the event.

An important part of this session was the presentation of the America Makes and ANSI Standardization Roadmap for Additive Manufacturing (Version 2.0) and the Additive Manufacturing Standardization Collaborative (AMSC). Both could have a long-term impact on the adoption of AM around the world.

After 14 days on four continents, it was nice to return to Colorado. I like to meet with friends and make new ones, but it’s also good to be home with family and friends, especially over the holidays. (Thanksgiving is next week in the U.S.) The ski season is underway, so it’s time to visit the high country to take part in a sport that is relaxing and exhilarating. It’s a great compliment to a full and rewarding year of travel and work.

AM in Formula One

Note: Research associate Ray Huff authored the following.

Two weeks ago, I attended the Circuit of the Americas Formula One race near Austin, Texas. I was a guest of Additive Industries, along with the Sauber Alfa Romeo team, for practice day at the track. The day was rainy, but spirits were high, and we enjoyed the spectacle of heavily-engineered race cars burning down the track at speeds of more than 322 km (200 miles) per hour.

We watched the race from the Paddock Club, an incredible location just above the garages. At midday, we toured the pits and watched the premier teams conducting pit stop practice, vehicle maintenance, and inspection. The greatest treat of all was to meet Charles Leclerc and Marcus Ericsson, drivers of the Sauber team. The two young men were charming, amicable, and laser-focused on their task when it was race time.

Formula One is an amazing use case for AM. Each car is effectively a custom product, with a new design each year. Performance is the number one priority, with an emphasis on stiffness and weight. The cars and drivers are supported by teams of hundreds of engineers, mechanics, and others. Team budgets famously soar in the range of hundreds of millions of dollars. Each F1 team is allowed to bring a maximum of 60 crew members on race day at each of their 21 races throughout the year. I was completely inspired and impressed at the amount of engineering involved in this sport, and look forward to more races in the future.

AM in Africa

October 21, 2018

Filed under: 3D printing,additive manufacturing,CAD/CAM/CAE,education,event — Terry Wohlers @ 07:29

Yesterday, I recently returned from my 22nd visit to Africa. Twenty of them have been to South Africa where additive manufacturing activity is the strongest. In fact, I estimate that 99% of AM work on the continent has occurred in the country. Some limited activity is underway in Botswana, Egypt, Namibia, and Nigeria. Adoption has been especially strong at Central University of Technology, Vaal University of Technology, Stellenbosch University, and North-West University—all in South Africa.

The Government of South Africa has been supportive of AM, with the Council for Scientific and Industrial Research (CSIR) doing the most in a hands-on way. Among the companies that are leading the way is Aerosud, an 800-person supplier of parts and assemblies to Airbus and Boeing. Many other companies are benefiting from AM parts, but they do not own high-end equipment. A reseller network of companies for AM products has been in place for many years.

Central University of Technology (CUT) in Bloemfontein was the first to install multiple high-end industrial machines in South Africa. Its world-class Centre for Rapid Prototyping and Manufacturing (CRPM), shown in the following two images, continues to have the largest commercial impact in the country. Last year, the CRPM completed 580 projects consisting of ~13,500 AM parts. Twenty-five percent of the projects were medical cases, most of high complexity. The centre received ISO 13485 quality certification for medical devices in 2016, which has contributed to its capabilities.

CUT and its impressive CRPM served as host to last week’s three-day course on design for additive manufacturing (DfAM) conducted by Wohlers Associates. Twenty-five engineers and others participated, and many were advanced in their knowledge and experience in AM and DfAM when they arrived. Wohlers Associates has conducted many of these courses, the first in August 2015 for NASA Marshall Space Flight Center. One exercise involved the redesign of a manifold by the participants on the first day. Five of them were manufactured in titanium and delivered for inspection by the third day. Thanks to our good friends at the CRPM for helping to make this happen.

The previous images show the conventional manifold design (left) and five versions of the manifold produced by AM. One of the primary objectives of this hands-on, DfAM exercise was to reduce weight and substantially reduce or eliminate the need for support material, which can add substantial time and cost to a part. We are thankful to those who participated, for how engaging they were, and for their favorable feedback. It was one of our very best three-day DfAM courses. Thanks also to CUT and its CRPM for organizing the event and serving as such great hosts.

Inside 3D Printing – Seoul

July 2, 2018

Filed under: 3D printing,additive manufacturing,CAD/CAM/CAE,event,manufacturing — Terry Wohlers @ 17:00

I attended last week’s fourth annual Inside 3D Printing event near Seoul, South Korea. It has been interesting to watch the even grow over the past four years. A total of 10,532 people from 28 countries attended. The event, organized by Rising Media and KINTEX, included three days of exhibition with 80+ companies and a two-day conference with 42 speakers and panelists. Many of the presentations were excellent.

Alex Lalumiere, a director at HP in Singapore, gave one of six keynote presentations. He focused mainly on how HP, as a manufacturing company, is using Multi Jet Fusion (MJF) to produce parts that save time and money. The presentation, focused on the following drill extraction shoe, was one of most interesting and compelling that I’ve heard from HP. It is used to aid in the manufacture of an HP inkjet printhead.

The image at the far left shows aluminum parts that are conventionally manufactured and assembled to produce what you see in the middle. The optimized design, shown at the right, consolidates eight parts into one and was 3D printed by MJF in PA12. This improved design reduced weight from 575 grams (1.27 lbs) to 52 grams (0.11 lb), a savings of 91%. The cost to produce the drill extraction shoe was reduced from $450 to $18, a savings of 96%, according to HP.

The previous example is what’s possible with methods of design for additive manufacturing (DfAM). Wohlers Associates is conducting a three-day, hands-on DfAM course in the Rocky Mountains of Colorado.

Alan Parsons

June 3, 2018

Filed under: entertainment,event — Terry Wohlers @ 17:06

Note: Thanks to RØDE founder Peter Freedman and CEO Damien Wilson for connecting us with Alan Parsons. (Parsons uses world-class, award-winning microphones from RØDE. He will be gaining access to the latest 3D printing technology that RØDE and Wohlers Associates have been exploring. Some interesting new designs will be produced using an HP Jet Fusion machine, a system RØDE recently installed.)

If you grew up in the 1970s and like good rock ‘n roll music, you’re probably familiar with The Alan Parsons Project. Parsons is a musician, composer, record producer, and director. Among his band’s hits are Eye in the Sky, Games People Play, Sirius, and Time. My 31-song Spotify playlist includes music from the albums Tales of Mystery and Imagination, I Robot, Eye in the Sky, and others. I was introduced to Alan Parsons music in 1977 by good friend Gary James during our first year at the University of Nebraska at Kearney.

Parsons got his start at age 18 as an audio engineer at Abbey Road Studios in London. The 69-year-old Englishman engineered hit music with Paul McCartney, the Hollies, and Pink Floyd, including The Dark Side of the Moon. He was responsible for adding the brilliant saxophone part in Al Stewart’s Year of the Cat, which is a favorite. Last night’s concert at Levitt Pavilion in Denver, Colorado was the first in series of live performances this summer in the U.S, Mexico, Germany, and Poland. Alan Parsons is so incredibly talented and his band sounded fantastic.

My wife and good friends Bill and Stephanie Beyers were among a few people that spent time back stage with several of the band members. We talked with drummer Danny Thompson and guitarist Dan Tracey and Jeff Kollman, but spent the most time with keyboardist and Grammy Award winner Tom Brooks. We discussed the 3D printing of musical products and described the way the technology works. Our conversation with Parsons himself was brief, but good.

Alan Parsons and other rock legends will not be around forever. We lost Tom Petty and Glenn Frey before I got to see them perform live. My fear is that as these people and bands disappear, new rock ‘n roll musicians will not fill the void. Try to name one current-day rock band with several hits. Maybe a millennial can do it, but I cannot. In the meantime, we need to remind ourselves to take in live performances of renowned bands of the ‘70s such as the one last night.

Important Events in AM

April 22, 2018

Last week, I attended the 20th Annual FIRPA Conference in Espoo, Finland, which is about 20 km (12 miles) from Helsinki. The event included some excellent presentations, including one from Jonas Eriksson of Siemens Industrial Turbomachinery AB. Eriksson discussed the production of parts by additive manufacturing for land-based gas turbine engines. To date, the company has redesigned many parts for metal AM and used the technology to produce more than 1,000 burner tips. The use of AM has resulted in a time reduction from 26 weeks to just three. As many as 60 people are now focused on AM at the company, with a goal of making metal AM as simple as 2D printing on paper.

Another very interesting presentation was given by Jyrki Saarinen of the University of Eastern Finland. His group worked closely with Dutch company Luxexcel to produce an AM machine with 1,000 inkjet nozzles for the printing of optical lenses in PMMA. The surface finish of the printed lenses is <2 nm RMS (less than 2 billionths of a meter), so no post-processing is required. The machine is capable of producing 40 lenses per hour, each measuring 10 mm in diameter x 2.5 mm in height, so the process is relatively fast.

I also had the privilege of visiting two world-class companies in Finland. The first was KONE, an $11 billion manufacturer of elevators, escalators, exterior revolving doors, and security entrances for commercial buildings. The company and its products are impressive. I also visited UPM, a $12.3 billion company with a strong position in paper, pulp, plywood, composites, and bio products. The company recently entered the AM industry by introducing a material extrusion filament product consisting of cellulose fiber and PLA.

Last week’s trip to Finland could not have gone better, thanks to the fine people that organized the meetings and very successful 20th annual conference. This week, the focus is on RAPID + TCT 2018, which begins tomorrow and goes through Thursday in Fort Worth, Texas. This event marks the 26th annual conference and exposition, and I’m proud to say that I have not missed a single one of them. Attendance has grown by ~2.3 times over the past four years and exhibit space has grown by ~4.5 times over the same period. If you are interested in attending one of the very best events in all things additive manufacturing, 3D printing, and 3D scanning, go to Fort Worth this week. You will not regret it.
