Applications of 3D Printing in Architectural Restoration

Over the last century we’ve seen the aesthetic of building facades shift from ornately crafted, historical styles to more minimalist, sleeker designs. This simpler style arose from the presence of new technologies and materials including steel and concrete, as well as an emphasis on efficiency and utility, rather than ornamentation. The cost of restoring historic buildings has greatly increased as the number of craftsmen has dwindled. Many of these buildings are subsequently demolished and representations of historic architecture styles are erased. With the emergence of 3D printing technology, however, the possibilities of design and the preservation of these historical buildings are shifting again.

EDG’s
“Modern Ornamental” Method for Restoring Facades

In New York, architecture and engineering firm EDG developed a method for restoring historical buildings in the city called “Modern Ornamental.” The firm created complex molds to cast replicas of the parts needed to restore these buildings. 3D printing technology enables designers to scan any portion of a building and input the design and texture data into their 3D modeling software. Once the design information has been processed, a sturdy plastic mold of that part can be 3D printed. A mold would then be coated with a bond-breaker, inlaid with wire mesh and stirrups and cast with concrete. The design can then be catalogued and re-printed at any time. According to EDG, their process for printing and casting molds takes under a day to complete.

voxeljet’s Restoration of the Michael Portal at Cologne Cathedral

Directly 3D printing parts in different materials is also possible depending on the pieces involved. In Germany, 3DION 3D network and voxeljet teamed up to restore a piece of the Cologne Cathedral called the Michael Portal. After the portal was cleaned they decided to 3D print new replicas of the patrons of the Michael Portal. The 108 figures in the portal as well as existing plaster templates from the 19th century were 3D scanned and scaled and the patron replicas were printed from the CAD data over the course of one weekend using PMMA powder. The replicas were then reinforced by epoxy resin.

Sismaitalia’s
Capital Restoration at Spada Palace

Italian large format
digital printing company Sismaitalia produced five life-sized capitals for the
19th century Spada Palace in Ferrara by printing hollow replicas and filling
them with polyurethane foam. They were then finished with plaster and painted
to match the rest of the structure. This method ensured that manufacturing
costs would be kept to a minimum without foregoing the aesthetic.

Potential
for Restoring Notre Dame with 3D Printing

Notre-Dame Cathedral (Notre Dame de Paris)

After Notre Dame caught fire in 2019 and was severely damaged, it was clear the costs and the limits of historical materials would make restoration very difficult. Many of the materials originally used to build it no longer exist. However, with the use of 3D printing, a lot of the restoration work can be conducted at a much lower cost while maintaining authenticity and precision.

This has sparked ideas to utilize 3D printing for Notre Dame’s restoration. Dutch company Concr3de conducted a test print of one of Notre Dame’s gargoyles using a mixture of limestone and ash to stay as close to the original materials as possible. Kansas City company Dimensional Innovations proposed printing the entire iconic 300-foot spire. Now that full homes are 3D printable, it is not out of the question that larger scale components could be similarly printed as well.

The
Benefits of Using 3D Printing in Restoration

3D printing technology presents many solutions to restoring historic structures, buildings and monuments. The ability to precisely 3D scan any component of a building is a game changer when it comes to saving time and energy in recreating important pieces. Compared to crafting these pieces by hand, 3D printing can be a much more efficient process. 3D printed molds can be extremely high quality while producing less waste than other technologies, allowing more creativity and leeway than precast concrete.

Find out how you can utilize 3D printing to build your ideal architectural styles and influences without sacrificing cost.

3D Printing News Briefs: August 31, 2018

Welcome to this month’s last edition of 3D Printing News Briefs! Today, in honor a new month starting tomorrow, we’re starting with stories about everything new. BEEVERYCREATIVE will soon launch a new 3D printer kit, while Fast Radius is opening a new headquarters and Thor3D welcomes a new CEO. Verashape is introducing the latest version of its SOFTSHAPER software, and Link3D launched a new additive manufacturing scheduling solution. Moving on from new things, Midwest Engineered Systems, an official KUKA partner, will be displaying its technology at IMTS 2018, and a company used its innovative laser cladding technology to restore a CNC spindle.

BEEVERYCREATIVE’s New 3D Printer Kit

Portuguese 3D printer manufacturer BEEVERYCREATIVE is getting ready to launch a new 3D printer DIY kit, and will present it publicly for the first time at the upcoming TCT Show 2018 in Birmingham. This is a big deal for the company, as it hasn’t introduced had a product launch for a new 3D printer since 2015; employees have been very busy working on the MELT project for the European Space Agency for the last two years, and are more than ready to introduce the new B2X300 3D printer kit.

BEEVERYCREATIVE conduct multiple studies before the launch, including market research on 3D printer user patterns and collecting quantitative and qualitative information from users about its helloBEEprusa 3D printer kits. The B2X300 is named for the company’s brand (B), its two extruders (2X), and its 300 x 200 x 300 mm print area (300), and was delivered to several beta testers this spring for testing and feedback. Aside from its build area, number of extruders, and the fact that it features auto bed leveling and trinamic drivers, we don’t know much about the 3D printer kit yet. But all will be revealed by mid-September.

Fast Radius Opening New Headquarters and AM Factory

3D printing solutions provider Fast Radius is scaling up its manufacturing footprint, and recently opened its new headquarters in Chicago’s West Loop, which features an advanced, industrial-grade 3D printing facility. This facility is home to extensive HP MultiJet Fusion technology, as well as what the company calls the largest Carbon production facility in the Western Hemisphere. This was a well-thought out location: the building of the Chicago-based Digital Manufacturing and Design Innovation Institute (DMDII) was where the company’s new CEO Lou Rassey first collaborated with several other Fast Radius executives, including Chief Scientist Bill King, PhD, Chief Product Officer John Nanry, and Enterprise Solutions Leader John Ramirez. The rest of the company’s executive team includes Vice President of Sales and Marketing Brian Simms and COO Pat McCusker.

Rassey said, “It was important to the Fast Radius team that we were headquartered in Chicago, as we are passionate about being a part of the next great industrial manufacturing renaissance in this city, the Midwest, and ultimately, the world.

“Pat, John, Bill, John and Brian form the perfect core team to grow Fast Radius as we build out our technology platform and global footprint to bring manufacturing innovation to the world at scale.”

Thor3D Welcomes New CEO

Anna Zevelyov

This week, Moscow-headquartered 3D scanner manufacturer Thor3D announced that it has appointed its very first Chief Executive Officer. The new CEO, Anna Zevelyov, is a company co-founder and a 3D printing market veteran who had been serving as Thor3D’s Sales Director; her long-time lieutenant, Vadim Fomichev, will now be taking on this role. Under Zevelyov’s leadership, the company will be focusing on R&D, with plans to release at least one new 3D scanner each year.

“Some history…the company was, until now, ruled by committee. Although periodically, this “collective-wisdom” approach was beneficial, over time we realized that a strict hierarchy and one person at the helm is needed,” Zevelyov wrote in a statement. “The Board of Directors took 6 months to consider whether to nominate a CEO and if yes, who that might be. After much debate about how this could change the culture of the company, the decision was made this month. I was elected unanimously, which, naturally, boosts confidence, as I take on this new challenge.

“I am honored and optimistic. My first priority will be R&D (after all, Thor3D is, first and foremost, a technology company). My aim will be to significantly improve our current technology and to introduce a new 3D scanner at least once a year (expect to hear big news before the end of the year). Another priority will be organization of our intellectual property. I anticipate filing a number of international patents over the next year to formalize the innovative work that has been done in the company over the previous months.”

New SOFTSHAPER Software Version

Verashape, which manufactures the VSHAPER line of 3D printers, has just introduced the latest version of its SOFTSHAPER software. Thanks to a license granted to the company by Siemens PLM Software last year, SOFTSHAPER 2019 is based on Parasolid Communicator. There are many improvements and new features in this latest version of SOFTSHAPER, including a technological process tree, detailed reports, and the ability to group layers and print manually adjusted supports.

“A huge simplification that SOFTSHAPER 2019 provides us with is the ability to print supports with higher density,” explained Seweryn Nitek, a Software Engineer at Verashape. “The density is higher only in the area of contact with the model. In other areas, the density of supports is selected in relation to the required stiffness. This saves time for printing supports, which are then removed by the user.”

Midwest Engineered Systems Displaying KUKA Technology at IMTS 2018

Two years ago at IMTS 2016 in Chicago, KUKA Robotics showcased how its robots integrate with 3D technology thanks to partnerships with companies like Midwest Engineered Systems (MWES), a leader in complex systems integration. MWES provides services such as robotic welding, machine tending, material handling, and automated production lines, but has become well-known in the last few years for its work in laser wire additive manufacturing. This technology is able to create very large parts, while also saving up to 90% of the material normally machined away.

“We’ve actually come up with a way way to print with metal using wire. Really what that does is allows you to print larger parts and it allows you to print them faster,” said Scott Woida, the President of MWES, in a video.

The company’s additive manufacturing system uses the hot wire process to preheat wire before it enters the molten pool. At the upcoming IMTS 2018, you can check out the MWES technology for yourself at KUKA’s Booth N-236200.

Restoring CNC Spindle with Laser Cladding

A company called Synergy Additive Manufacturing LLC (SAM), which claims to be one of the only turnkey jobshops to offer metalworking services like final machining, heat treating, metal forming, 3D CAD design, and 3D printing, also developed a laser cladding process is a more cost-effective alternative to hard chrome coatings. The company offers a 24 hour turnaround on the dimensional restoration of rotating components, like motor shafts and CNC spindles, using this technology.

In a new video, SAM demonstrated how its laser cladding method can be used to restore a CNC spindle. The technology offers a good metallurgical bond, and there is no chipping away or peeling once the restoration is complete. You can see this for yourself in the video below:

3D Printing News Briefs: June 29, 2018

In today’s 3D Printing News Briefs (the last one this month, how is the summer going by so quickly?!), a few companies are announcing special honors and recognitions, and then we’re sharing stories stories about some interesting new 3D printing projects, and finally wrapping things up before the weekend with some business news. Renishaw’s Director of R&D has been honored by the Royal Academy of Engineering, while MakerBot earned an important designation for its 3D printing certification program for educators and Renovis Surgical Technologies received FDA approval for its new 3D printed implant. Festo is introducing three new bionic robots, one of which is partially 3D printed, and CINTEC is using 3D printing for its restoration of a famous government house. GE wants to use blockchains for 3D printing protection, and ExOne announced a global cost realignment.

Royal Academy of Engineering Honors Renishaw’s Chris Sutcliffe

Earlier this week, the Royal Academy of Engineering (RAE) awarded a Silver Medal to Professor Chris Sutcliffe, the Director of Research and Development of the Additive Manufacturing Products Division (AMPD) for global metrology company Renishaw. This award is given to recognize outstanding personal contributions to British engineering, and is given to no more than four people a year. The Silver Medal Sutcliffe received was in recognition of his part in driving the development of metal 3D printed implants in both human and veterinary surgery, and also celebrates his successful commercialization of 3D printed products with several companies, including Renishaw, and the University of Liverpool.

“Throughout my career I’ve worked hard to commercialise additive manufacturing technology. As well as AM’s benefit to the aerospace and automotive sectors, commercialisation of AM and associated technologies has been lifechanging for those with musculoskeletal diseases,” said Sutcliffe. “The award celebrates the successes of the engineers I have worked with to achieve this and I am grateful to receive the award to recognise our work.”

MakerBot’s Certification Program for Educators Gets Important Designation

One of the leaders in 3D printing for education is definitely MakerBot, which has sent its 3D printers to classrooms all over the world. Just a few months ago, the company launched a comprehensive, first of its kind 3D printing certification program, which trains educators to become 3D printing experts and create custom curriculum for STEAM classrooms. An independent review of the program showed that it meets the International Society for Technology in Education (ISTE) standards, and it has earned the prestigious ISTE Seal of Alignment from the accreditation body. In addition, a survey conducted over the last three years of over 2,000 MakerBot educators shows that the percentage of teachers reporting that MakerBot’s 3D printers met their classroom needs has doubled in just two years.

“This data shows that MakerBot isn’t just growing its user base in schools. We’re measurably improving teachers’ experiences using 3D printing,” said MakerBot CEO Nadav Goshen. “Much of this impressive teacher satisfaction is thanks to the effort we’ve put into solving real classroom problems—like the availability of 3D printing curriculum with Thingiverse Education, clear best practices with the MakerBot Educators Guidebook, and now training with the new MakerBot Certification program.”

Earlier this week, MakerBot exhibited its educator solutions at the ISTE Conference in Chicago.

FDA Grants Clearance for 3D Printed Interbody Spinal Fusion System 

California-headquartered Renovis Surgical Technologies, Inc. announced that it has received 510(k) clearance from the FDA for its Tesera SA Hyperlordotic ALIF Interbody Spinal Fusion System. All Tesera implants are 3D printed, and use a proprietary, patent-pending design to create a porous, roughened surface structure, which maximizes biologic fixation, strength, and stability to allow for bone attachment and in-growth to the implant.

The SA implant, made with Renovis’s trabecular technology and featuring a four-screw design and locking cover plate, is a titanium stand-alone anterior lumbar interbody fusion system. They are available in 7˚, 12˚, 17˚, 22˚ and 28˚ lordotic angles, with various heights and footprints for proper lordosis and intervertebral height restoration, and come with advanced instrumentation that’s designed to decrease operative steps during surgery.

Festo Introduces Partially 3D Printed Bionic Robot

German company Festo, the robotics research of which we’ve covered before, has introduced its Bionic Learning Network’s latest project – three bionic robots inspired by a flic-flac spider, a flying fox, and a cuttlefish. The latter of these biomimetic robots, the BionicFinWave, is a partially 3D printed robotic fish that can autonomously maneuver its way through acrylic water-filled tubing. The project has applications in soft robotics, and could one day be developed for tasks like underwater data acquisition, inspection, and measurement.

The 15 oz robot propels itself forward and backward through the tubing using undulation forces from its longitudinal fins, while also communicating with and transmitting data to the outside world with a radio. The BionicFinWave’s lateral fins, molded from silicone, can move independently of each other and generate different wave patterns, and water-resistant pressure and ultrasound sensors help the robot register its depth and distance to the tube walls. Due to its ability to realize complex geometry, 3D printing was used to create the robot’s piston rod, joints, and crankshafts out of plastic, along with its other body elements.


Cintec Using 3D Printing on Restoration Work of the Red House

Cintec North America, a leader in the field of structural masonry retrofit strengthening, preservation, and repair, completes structural analysis and design services for projects all around the world, including the Egyptian Pyramids, Buckingham Palace, Canada’s Library of Parliament, and the White House. Now, the company is using 3D printing in its $1 million restoration project on the historic Red House, which is also known as the seat of Parliament for the Republic of Trinidad and Tobago and was built between 1844 and 1892.

After sustaining damage from a fire, the Red House, featuring signature red paint and Beaux-Arts style architecture, was refurbished in 1904. In 2007, Cintec North America was asked to advise on the required repairs to the Red House, and was given permission to install its Reinforcing Anchor System. This landmark restoration project – the first where Cintec used 3D printing for sacrificial parts – denotes an historic moment in structural engineering, because one of the reinforcement anchors inserted into the structure, measuring 120 ft, is thought to be the longest in the world.

GE Files Patent to Use Blockchains For 3D Printing Protection

According to a patent filing recently released by the US Patent and Trademark Office (USPTO), industry giant GE wants to use a blockchain to verify the 3D printed parts in its supply chain and protect itself from fakes. If a replacement part for an industrial asset is 3D printed, anyone can reproduce it, so end users can’t verify its authenticity, and if it was made with the right manufacturing media, device, and build file. In its filing, GE, which joined the Blockchain in Transport Alliance (BiTA) consortium in March, outlined a method for setting up a database that can validate, verify, and track the manufacturing process, by integrating blockchains into 3D printing.

“It would therefore be desirable to provide systems and methods for implementing a historical data record of an additive manufacturing process with verification and validation capabilities that may be integrated into additive manufacturing devices,” GE stated in the patent filing.

ExOne to Undergo Global Cost Realignment

3D printer and printed products provider ExOne has announced a global cost realignment program, in order to achieve positive earnings and cash flow in 2019. In addition to maximizing efficiency through aligning its capital resources, ExOne’s new program will be immediately reducing the company’s consulting projects and headcount – any initial employee reductions will take place principally in consulting and select personnel. The program, which has already begun, will focus first on global operations, with an emphasis on working capital initiatives, production overhead, and general and administrative spending. This program will continue over the next several quarters.

“With the essential goal of significantly improving our cash flows in 2019, we have conducted a review of our cost structure and working capital practices. We are evaluating each position and expense within our organization, with the desire to improve productivity. As a result, we made the difficult decision to eliminate certain positions within ExOne, reduce our spending on outside consultants and further rely on some of our recently instituted and more efficient processes,” explained S. Kent Rockwell, ExOne’s Chairman and CEO. “Additional cost analyses and changes to business practices to improve working capital utilization will be ongoing over the next several quarters and are expected to result in additional cost reductions and improved cash positions. All the while, we remain focused on our research and development goals and long-term revenue growth goals, which will not be impacted by these changes, as we continue to lead the market adoption of our binder jetting technology.”
