We’re still in the midst of the COVID-19 pandemic, but it seems like there’s at least a small light at the end of the tunnel as businesses and services begin to open their doors once again. This is also a pretty important time for hospitals right now, since they are starting to perform surgical procedures again. Obviously, the crisis has created a pretty big surgery backlog, which is why Fast Radius and Axial3D are teaming up to create better 3D-printed anatomical models for surgical planning.

By using 3D technologies in surgical planning, clinicians can enjoy a higher standard of medical imaging, which enables them to have more insight into the unique anatomical details of different patients. Before they’re anywhere close to the operating room, the surgeons can hold 3D-printed anatomical models in their own two hands and take a much closer look at what they’ll be dealing with. Not only does this allow them to better define, and even practice, surgeries ahead of time, but patients can also handle the models in order to gain a better understanding of what’s going on in their bodies.
“The partnership between Fast Radius and Axial3D comes at a critical time for healthcare institutions. We are now able to support surgeons and hospitals in the US minimize the impact of COVID 19 as they endeavor to return elective surgery capacity,” explained Roger Johnston, the CEO at Axial3D.
Belfast-based healthcare technology firm Axial3D is focused on the global adoption of 3D printing in the healthcare industry, and its patient-specific 3D-printed medical models are award-winning. By partnering with Chicago-headquartered digital manufacturing solutions provider Fast Radius, clinicians all across North America will be able to make much more precise surgical plans than what 2D imaging can offer, according to the partners.

Together, the two companies have developed what they consider a high-volume, high-quality DICOM-to-print service that will allow hospitals and surgeons in Canada, Mexico, and the United States to fabricate patient-specific 3D anatomical models, at high speeds, with an accuracy of micro-millimeters. They’ll use patient 2D scans to create the models, and once they’re 3D printed, they will be shipped to the hospitals within a minimum of 48 hours. How’s that for service?
“Our mission at Fast Radius is to help companies make new things possible that advance the human condition. Partnering with Axial3D to make these surgical models will have a great impact on patient care. It’s work we’re proud to do,” said Lou Rassey, the CEO at Fast Radius.

While bone defects are already a challenge to manage, obviously the problem is compounded in children, with smaller bones being even more difficult to repair in surgery. Currently, there are few options for a good device meant for small bone repair during pediatric osteotomies—making it difficult for surgeons around the world to correct both subluxated hip joints and deformed femurs in children.
The authors (and surgeons) performed corrective surgery on a four-year-old boy with a post-osteomyelitis deformity. In preparing for the surgery, they relied on a 3D printed model of the bone for studying the condition, surgery and preparing the site for the appropriate implant. Because this type of surgery requires ‘meticulous planning,’ the doctors required both 2D and 3D assistance, in the respective forms of axial images and 3D virtual models of patient anatomies.

As the surgeons examined the patient and reviewed the CT, they noticed a genu valgus deformity (more commonly known as a ‘knock-knee’ condition). Another corrective surgery was scheduled, with 3D CT imaging examined for bone tissue analysis. The surgeons realized, however, that the procedure would be more successful overall with a life-size 3D model. They were able to outline a patient-specific plan, also bringing in additional assistance from an orthopedic consulting firm focused around 3D orthopedics and ‘patient-specific instrumentation.’

(c) Correcting the femoral rotation would result in joint translation in both the coronal and axial planes
What was also very valuable to the surgery—and the outcome for the little boy involved—was that the surgeons could use the model to practice on, exercising ‘simulations of possible osteotomy options.’
“After a few osteotomy options had been analyzed, one osteotomy cut was made vertically to the femoral shaft on the subtrochanteric area, and another was made on the middle third of the femur to correct the bowing deformity of the midshaft,” stated the researchers. “Correction of femoral rotation can result in either joint translation in the coronal and axial planes or difficulty with fixation, both of which could be prevented with the help of the 3D model in the present case.”
The results of the surgeries were successful, with the patient able to stretch and begin other mobilization activity after four months.

“The result of our case suggests that the use of 3D printing models improves the postoperative performance as shown by both physical function and radiological evidence,” stated the authors in the concluding discussion.
“The use of a 3D-printed patient-specific guide is a safe, modern, affordable, and promising method that offers advantages including a shorter surgical time, optimally positioned implant placement, acceptable alignment, and a probable lower rate of complications. The utilization of 3D-printed models for skeletal deformity surgery, especially complex and difficult pediatric surgery, provides superior precision and foreseeably better outcomes. We strongly believe that with the promotion of 3D printing methodology, models for preoperative planning may soon become the gold standard for pediatric deformity correction surgery.”

Optomec has announced two new additions to its LENS series, and CRP Technology is introducing a new commercial strategy for its Windform composite materials. HP India is building a new Center of Excellence for 3D Printing, while the South Korean government continues its investment in the technology. The GE Additive Education Program is now accepting applications for 2019-2020, and a Philadelphia-based university and health system has integrated Ultimaker 3D printers into its teaching curriculum. Speaking of health, Sweden is looking into 3D printing food for the elderly.
Optomec’s New LENS Systems
This week, production-grade metal 3D printer supplier Optomec announced that it was releasing two new Directed Energy Deposition (DED) 3D printers in its Laser Engineered Net Shaping (LENS) Classic System Series: the CS 600 and the CS 800 Controlled Atmosphere (CA) DED Systems. Both of the systems are configurable, and are designed to maximize the process build envelope, while at the same time lowering the system footprint and chamber volume. They have CA chambers that make it possible to process both non-reactive and reactive metals, and are both compatible with the company’s latest generation LENS deposition head.
“These new systems come packed with next-generation DED components all born from signature Optomec know-how and built to provide affordable, high-quality metal additive manufacturing capabilities for industry’s most demanding requirements. The LENS CS 600 and CS 800 systems represent the latest in DED processing from precision deposition to cladding applications and extend our product portfolio to continue to provide high-value metal additive manufacturing solutions,” said Tom Cobbs, Optomec’s LENS product manager.
The first customer shipments of the CS 600 and the CS 800 CA systems have already begun this year.
New Commercial Strategy for Windform Materials
CRP Technology has for years made components and also sold its Windform composite materials. Now the company has decided to revise its commercial strategy for the materials: from now on, they will no longer be sold to service bureaus for the toll-manufacturing of 3D printing components. However, the materials will continue to be sold to companies that produce their own components, while CRP Technology and CRP USA will continue to offer support for service and assistance in producing Windform parts.
“The change in the strategy of CRP Technology is because we believe we can ensure the highest quality in the manufacture of 3D printed components; indeed the increase in production capacity -both in Europe and in the United States- will guarantee the volumes necessary to satisfy any request from our customers based all over the world, in compliance with the high standards of service and quality that has always been a distinctive element of CRP Technology and CRP USA’s activities,” CRP Technology told 3DPrint.com in an email.
HP Building Center of Excellence for 3D Printing in India
HP introduced its Jet Fusion 4200 3D Printing solutions to India last year, and is now planning to build a Center of Excellence (CoE) for 3D Printing in Andhra Pradesh, which is the country’s seventh-largest state. This week, the company signed a Memorandum of Understanding (MoU) with the Andhra Pradesh government to build the CoE, which will give small and medium businesses (SMBs) and startups in the state the opportunity to learn more about the benefits of adopting 3D printing. HP India will be the main knowledge provider for the CoE, while the Andhra Pradesh Innovation Society (APIS) will enable accreditations and certifications and provide infrastructure support, and the Andhra Pradesh Economic Development Board (APEDB) will encourage and drive public sector enterprises and government departments to use the CoE.
“Manufacturing in Andhra Pradesh has great potential as a lot of demand is slated to come from domestic consumption,” said J. Krishna Kishore, the CEO of APEDB. “Andhra Pradesh’s impetus in automotive, electronics and aerospace makes technologies like 3D printing market-ready.”
South Korea Continues to Invest in 3D Printing
For the last couple of years, the government of South Korea has been investing in 3D printing, and 2019 is no different. The country’s Ministry of Science and ICT announced that it would be spending 59.3 billion won (US $52.7 million) this year – up nearly 17% from its 2018 investment – in order to continue developing 3D printing expertise to help nurture the industry. According to government officials, 27.73 billion of this will be allocated to further development of 3D printing materials technology, and some of the budget will go towards helping the military make 3D printed components, in addition to helping the medical sector make 3D printed rehab devices.
“3D printing is a core sector that can create innovation in manufacturing and new markets. The ministry will support development by working with other related ministries and strengthen the basis of the industry,” said Yong Hong-taek, an ICT ministry official.
GE Additive Education Program Accepting Applications
In 2017, GE Additive announced that it would be investing $10 million in the GE Additive Education Program (AEP), an educational initiative designed to foster and develop students’ skills in additive manufacturing. To date, the global program has donated over 1,400 polymer 3D printers to 1,000 schools in 30 different countries, and announced this week that it is now accepting applications for the 2019-2020 cycle from primary and secondary schools. While in previous years the AEP also awarded metal 3D printers to universities, that’s not the case this time around.
“This year’s education program will focus only on primary and secondary schools,” said Jason Oliver, President & CEO of GE Additive. “The original purpose of our program is to accelerate awareness and education of 3D printing among students – building a pipeline of talent that understands 3D design and printing when they enter the workplace. We already enjoy some wonderful working relationships with universities and colleges, so this year we have decided to focus our efforts on younger students.”
The deadline for online AEP applications is Monday, April 1st, 2019. Packages include a Polar Cloud premium account, a Polar Cloud enabled 3D printer from either Dremel, Flashforge, or Monoprice, rolls of filament, and – new this round – learning and Tinkercad software resources from Autodesk. Check out the video below to learn about GE Additive’s ‘Anything Factory’ brand campaign, the heart of which was formed by a young student who had just discovered 3D printing and what it’s capable of creating…this is, of course, the purpose behind AEP.
Ultimaker 3D Printers Integrated into Medical Teaching Curriculum
Dr. Robert Pugliese and Dr. Bon Ku of Philadelphia’s Thomas Jefferson University and Jefferson Health wanted to better prepare their students for real-world hospital challenges, and so decided to integrate Ultimaker 3D printers into the system’s Health Design Lab. The Lab is used for multiple medical and educational applications, from ultrasound training and cardiology to ENT surgery and high-risk obstetrics, and students are able to work with radiologists on real patient cases by helping to produce accurate anatomic models. The Lab houses a total of 14 Ultimaker 3D printers, including the Ultimaker 2+ Extended, the Ultimaker 3, and the Ultimaker S5, and the models 3D printed there help enhance patient care and improve surgical planning, as well as teach students how to segment critical features and interpret medical scan data.
“When we introduce these models to the patients their eyes get big and they ask a lot of questions, it helps them to understand what the complexity of their case really is. It’s just so much better to have the patient on the same page and these models really help bring that reality to them,” said Dr. Amy Mackey, Vice Chair of the Department of Obstetrics and Gynecology at Jefferson’s Abington Hospital.
3D Printing Food for the Elderly in Sweden

If you’ve attended a meal at a nursing home, or care home, then you know the food that’s served is not overly appetizing. This is because elderly people can also just have a more difficult time eating regular food. Roughly 8% of adults in Sweden have trouble chewing or swallowing their food, which can easily cause them to become malnourished. That’s why the Halmstad municipality on the country’s west coast wants to use 3D printing to stimulate these residents’ appetites, which will be accomplished by reconstituting soft, puréed food like chicken and broccoli to make it look more realistic.
Richard Asplund, a former head chef at the luxury Falkenbergs Strandbad hotel who’s now the head of Halmstad’s catering department, said, “When you find it hard to chew and swallow, the food that exists today doesn’t look very appetising.
“So the idea is to make something more aesthetic to look at, to make it look good to eat by recreating the original form of the food.”
The state innovation body Rise is coordinating the project, which is currently in the pre-study phase and plans to serve the first 3D printed meals in Halmstad and Helsingborg by the end of this year.
