Pressing Matters – Issue 7 http://bit.ly/2Qw1Fgw For their seventh fantastic issue, the independently-run Pressing Matters magazine has spoken to a fascinating mix of makers, all with very different ways of working but all sharing a big love for print. This issue focuses on the interesting topic of how an artist chooses to tell a story through print. You can find a series of tales in the tree ring prints by Nice Art People, stories in the ethereal cyanotypes of Craig Keenan and an animated fable of a journey into the afterlife (made using collagraph prints) by Marine Rivoal and Claire Sichez. For a printmaker, finding inspiration for a print or series of work is often a daunting task, and knowing where to start can be a tricky thing. Issue 7 explores how these printmakers use shape, colour and texture with ink and paper to create something totally unique. Be it describing landscapes, imagined or real, like Nicholas Perra and Andy Lovell, or using found objects and paper cut scraps for abstract prints like Claire Willberg and Jonathan Lawes. Another epic journey features Jack Blake and Barbara Salvadori packing their panniers and cycling the paper road in search of papermakers, absorbing their unique knowledge and techniques and finding that although the tools and people may be different all over the world, they all share a love for the handmade. This issue is a real joy to see how people play with print! You can purchase Pressing Matters 07 and selected back issues on Department Store and below.

Moving on to interesting 3D printing projects, an artist teamed up with Mimaki to use full-color 3D printing to make a stage prop, a reddit user created an anti-cat button for an Xbox system, and an imgur user created a modular 3D printed fashion system. euspen to Hold Special Interest Group Meeting on AM The European Society for Precision Engineering and Nanotechnology (euspen) will be addressing the factors which are influencing an uptake of the use of additive manufacturing as a production technology at a Special Interest Group (SIG) meeting in September. The meeting, which will be co-hosted by the American Society of Precision Engineering (ASPE), will analyze the barriers to, and the opportunities for, the adoption of AM in production. It will be held from September 16-18 at the École Centrale de Nantes in France. At the AM SIG meeting, issues that are, as euspen put it, “critical to the viability of AM as a production technology,” will be addressed. The co-chairs of the meeting are Professor Richard Leach from the University of Nottingham and Dr. John Taylor from the University of North Carolina at Charlotte. Local hosts and the organizing committee include Professor Alain Bernard from Centrale Nantes, Dr. David Bue Pedersen from the Technical University of Denmark, Professor Leach, and Dr. Taylor. Comparison of Small and Large SLS 3D Printers 3D printers are often used in educational settings these days. Piotr Dudek, an adjunct professor at the AGH University of Science and Technology in Poland, runs a 3D printing lab at the school that both students and researchers frequent. While many technologies are used in the lab, SLS is the one that most interests Dudek, who decided to compare a big SLS system from EOS with the smaller Sinterit Lisa.
Larger 3D printers obviously have higher print volumes, but the down sides include difficult calibration, specialized training, and higher costs. In addition, it’s easy to mess up the calibration of a large 3D printer during transport. The Lisa 3D printer uses a gantry system, which comes pre-calibrated to save time, and it also uses less material, which means less money. The desktop printer is also much more student-friendly, making it the better choice for 3D printing labs like the one Professor Dudek runs. VIDEO Full-Color 3D Printed Stage Prop A few months ago, 3DPrint.com heard from 3D printing specialist and Post Digital Artist Taketo Kobayashi, from the Ultra Modelers community, about an art exhibit in Japan that he helped organize which featured colorful, 3D printed works created on the Mimaki 3DUJ-553 full-color 3D printer. Recently, he reached out to us again with news of his latest Mimaki Engineering collaboration – a stage prop for the Japanese artist Saori Kanda, who performed with techno/trance band Shpongle at the Red Rocks Amphitheater in Colorado.
The “Shpongle Mask,” which took 28 hours to print and mixed in Asian details, was worn onstage by Kanda as she performed her painting live with the band. 3D Printed Anti-Cat Xbox Button reddit user Mbiggz was getting sick of their cat turning off the touch-sensitive button on the Xbox console while it was in use, which I can understand, having two cats of my own. So Mbiggz came up with the perfect solution – a 3D printed cover for the button. The design can be found on the maker’s Tinkercad account, as Mbiggz originally made the design for a Digital 3D class.
3D Printed Modular Fashion System hunter62610, a young imgur user, designed and 3D printed a Lego-like modular fabric system, which was featured in his school’s fashion show. He made two dresses that are made with a 3D printed prototype fabric pattern called Escher, which was designed to be “put together and taken apart” hundreds of times. It took him just two weeks to make the material, which the two young ladies who modeled the dresses said was fairly comfortable.
A Makerbot Replicator Plus was used to print the fabric links in unique, small panels.

In a circular system resource input and waste, emissions, and energy leakage are minimized by slowing, closing, and narrowing energy and material loops; this can be achieved through long-lasting design, maintenance, repair, reuse, re-manufacturing, refurbishing, and recycling. This regenerative approach is in contrast to the traditional linear economy, which has a ‘take, make, dispose’ model of production. Proponents of the circular economy suggest that a sustainable world does not mean a drop in the quality of life for consumers, and can be achieved without loss of revenue or extra costs for manufacturers. The argument is that circular business models can be as profitable as linear models, allowing us to keep enjoying similar products and services. The economy we operate within currently is a mixture of two economies: linear economy and the reuse economy. The linear economy refers to how raw materials are used to make a product, and after its use any waste (e.g. packaging) is thrown away. The reuse economy refers to how In an economy based on recycling, materials are reused. For example, waste glass is used to make new glass and waste paper is used to make new paper. A linear and reuse economy still has an end product of non reusable waste within product creation. A circular economy would be oriented towards eliminating non reusable waste. According to the report What a Waste 2.0, the world is on a trajectory where waste generation will drastically outpace population growth by more than double by 2050. Although we are seeing improvements and innovations in solid waste management globally, it is a complex issue and one that we need to take urgent action on. Solid waste management affects everyone; however, those most affected by the negative impacts of poorly managed waste are largely society’s most vulnerable—losing their lives and homes from landslides of waste dumps, working in unsafe waste-picking conditions, and suffering profound health repercussions. The world generates 2.01 billion tonnes of municipal solid waste annually, with at least 33 percent of that—extremely conservatively—not managed in an environmentally safe manner. Worldwide, waste generated per person per day averages 0.74 kilogram but ranges widely, from 0.11 to 4.54 kilograms. Though they only account for 16 percent of the world’s population, high-income countries generate about 34 percent, or 683 million tonnes, of the world’s waste. It is important to focus on 3D Printing and the additive manufacturing industry as a whole. This is the future of manufacturing in a sense. Major manufacturing companies are responsible for the majority of our waste production within the world. A major concern for companies is indeed the bottom line. But it can be argued by proponents of the circular economy that a company may gain more from altruistic behavior oriented towards the environment. Additive manufacturing is a process that already is minimizing waste compared to previous methods of production that large manufacturers are used to. What are companies and organizations doing worldwide for this? Additive Manufacturing and Waste 3D printing and additive manufacturing methods help to minimize excess waste in production, but they are still operating within a linear mindset of production. This refers to how we create a product through design and then send it out for use by an individual. After this product has done its use it may then be terminated, and could lead to similar problems of previous manufacturing methods. It also may be worse as rapid creation of parts can lead to larger aggregates of waste overall in the future. 3D printing and additive manufacturing allow users and organizations to have localized production, This allows for better control over waste steams and for lower C02. Waste reduction occurs naturally as there is transparency with local production And quality control and quick turnover are also important considerations when using additive manufacturing as the basis of a circular economy. With 3D printing, in some cases, we can recycle a number of existing materials into 3D printed things. I shall be investigating waste and the ideals of the circular economy. I will try to shed light on larger companies and organizations that contribute to waste largely, as well as organizations that are doing their best to be sustainable and lead towards a more circular economy.

This week, the Kickstarter darling company announced something new – the 3Doodler Juku pen. The company has partnered with Office Depot, and this collaboration includes the launch of the Juku as part of an exclusive new STEAM educational kit series, which are now available for purchase in Office Depot and OfficeMax stores.
3Doodler was interested in partnering with Office Depot because it’s one of North America’s largest education retailers, with many years of experience in direct sales of educational products to schools, their districts, teachers, and students. The company’s position in the education sector aligns with 3Doodler’s goal of expanding the use of its products into the classroom. Over 8,000 classrooms across North America already use 3Doodler products, and by partnering with the popular educational supplier, even more school districts will have access through their existing relationships with Office Depot.
While 3Doodler has been focused on STEM and STEAM education for quite some time, its new collaboration with Office Depot is the company’s first partnership that’s focused on EDU products. The 3Doodler-specific Juku pen kit, which includes two packages of PLA filament, retails for $74.99 and is available to purchase online and at one of Office Depot’s over 2,000 stores; class pack discounts are available on bulk orders to the company’s Business Solutions Division educational customers. The new 3D printing pen, designed for users ages 12 and up, is not dissimilar to the design of last year’s Create+ pen, with the ability to draw in ABS, Flexy, and PLA plastic and dual drive functionality. In addition, the Juku is also compatible with wood filaments from 3Doodler. Three other Juku-branded activity kits make up Office Depot’s new educational series. The Juku STEAM Making Music Coding Kit teaches users to build their own instruments, and includes cables so the pen can be connected to the computer, where Scratch programming language can be used to create unique melodies. The Juku STEAM Light Games Coding Kit uses Scratch programming language so users can make their own games and bring them to life, while the Juku STEAM LED Light Show Coding Kit teaches users how to code LED lights in order to perform various effects and animations. This summer, Office Depot will display its new Juku line at several of the top educational conferences, including PTA and ISTE. In addition, I just so happen to have the 3Doodler Juku 3D printing pen in my possession, having been shipped a sample unit for review. I’m excited to put this product through its paces, so keep posted for my future review of the Juku.

NASA MSFC Materials & Process Development Offers Plan for New 3D Printing Materials & Hardware to Sustain Astronauts During Missions http://bit.ly/2Xe8WEj Not surprisingly, NASA is working on new developments for space travel—partnering with Auburn University to create new sensing technology, materials for 3D printing in space, as well as new hardware and capacitors (devices used to store electricity). In the latest from NASA MSFC Materials & Process Development, their goal is to create processes that can sustain production, recycling, and maintenance on-demand while astronauts are completing exploration missions. Beginning with a variety of different sensing platforms, the Materials & Process Development document outlines plans for flexible sensing technology such as next-generation printed sensors and platforms to be used for monitoring the health of astronauts while at the International Space Station (ISS), along with the specific, unique materials and new processes to create such devices. The document also outlines the need for both assessing and integrating wireless communications and flexible parts. For energy storage technology development, the following needs are outlined:
There are further plans to collaborate with other organizations and universities to create an In-Space Manufacturing Digital Design & Verification Database, along with another catalog of what parts and systems are to be created during missions. NASA also plans to create new laboratory methods such as:
For particle size measurements in nanotechnology, NASA’s intention is to understand mean particle size and distribution aids in powder milling for uniform sizing. Along with that, sample preparation is vital to gathering proper data. They also plan on developing nano-inks through formulation with ceramic and metallic powders and additives, along with creating ‘thick film ink formulations’ with three-roll mills:
For 3D printing, the nScrypt 3D multi-material printer is targeted as hardware of choice, featuring:
The idea overall is to be creating a FabLab at the ISS, that will also include a direct current sintering furnace, for developing ultracapacitor and thermoelectric materials. There are also plans for development of both Perovskite Ultracapacitors (used to store energy, and test and charge instruments and devices) and Plasma Sintered (SPS) Supercapacitors (offering good potential for high energy density). NASA has been using 3D printing for decades—long before anyone even knew what it was. In the past few years, however, as the technology has been launched into the mainstream with growing popularity, there have been numerous challenges where NASA encourages participants to compete in creating new 3D printing technology for the Moon and Mars, as well as space habitats and more. Researchers have studied different experimental filaments for use in space, as well as created devices for astronauts to test their own blood in space. Find out more regarding the latest in NASA developments here. What do you think of this news? Let us know your thoughts! Join the discussion of this and other 3D printing topics at 3DPrintBoard.com.

3D Printed Scaffolds Evaluated for Mandibular Reconstruction http://bit.ly/2KbRFIl In ‘Digital Design, Analysis and 3D Printing of Prosthesis Scaffolds for Mandibular Reconstruction,’ we learn more about strides in the medical field regarding mandibular surgeries, reconstruction, the potential for current and future improvements in implants, as well as understanding more about the obstacles today and how they can be overcome. 3D printing is invaluable to the medical field overall due to the ability to customize nearly everything—and offer patient-specific care to individuals who may have faltered under previous one-size-fits-all restrictions. Customized implants especially are offering new options to patients, as porous, lightweight structures can be created to aid in reconstruction and the eventual return to normal functions such as chewing and swallowing nutrients. For this study, Saudi researchers from King Saud University created two different customized scaffold designs (a top and bottom plate, and an inner porous plate) which they later evaluated regarding both usefulness and aesthetic appearance. The authors describe the perfect scaffold as one that is highly porous, without cracks, and fully biocompatible. Previous studies have shown that titanium is highly effective as a material but may also lead to deterioration of mechanical properties and eventual resorption or failure of the implant. 3D printing has offered potential in reconstruction, but also rehabilitation, and surgery too.
Until now, the researchers state that there has been no clear research regarding mandibular reconstruction or biomechanical properties, stability and integrity, or testing of related scaffolds and structures. Here, they studied a patient, at 40 years old, suffering from deformities and a ‘lesion in the left mandibular area.’ The patient was treated in an emergency department initially, beginning with a series of CT scans uncovering a mandibular continuity defect, and substantial loss of bone. The images were converted into 3D files using Materialise Mimics software, and then an FDM 3D printer was used with ABS material to create the framework model. A Formlabs 2 SLA 3D printer was then used for fabrication of the mandibular prosthesis scaffold. The researchers evaluated the structures for weight, integrity, and accuracy, using a micro-CT scan.
Mandibular reconstruction can be a challenging endeavor, but when successful it offers incredible value to patients who may be having trouble chewing, as well as enduring understandable self-consciousness due to a defect or tumor removal. This is big topic of research and has also led to numerous innovations via 3D printing, from alveolar ridge augmentation to mandibular grafts, and implants for cancer patients.

From entrepreneurs to students, industry experts and academia, even medical and dental professionals were invited to network in an environment embracing the impact of 3D printing in the industry and healthcare sectors. Attendees were also able to print their projects for free at the fully-equipped university 3D Lab, which is home to a Stratasys J750 PolyJet 3D printer, two Fortus 250mc, a Fortus 450mc, an Objet Alaris30, a CNC machine, and two desktop printers. The two-day event aimed to highlight the growing capabilities of 3D printing in the region, also provided the industry a place to discuss the future of 3D technology. Experts from ITBA, Stratasys, Hornero 3DX, and Garrahan Children’s Hospital shared their experiences with 3D printing models, materials and applications. Some of the topics discussed included 3D bioprinting, 3D facial scanning, and software, 3D printing in a nuclear power station, as well as the making of splints using 3D scanning and 3D printing. Si3d is a must-attend on the annual calendar in Argentina, where only two major 3D printing events take place every year and the local 3D printing industry is taking longer than expected to take-off.
While dozens of students, 3D printing enthusiasts, and business owners walked through the packed corridors of the university, stopping by each stand, speaking to the experts about some of the challenges that arise during 3D printing, workshops and panels showcased successful projects in 3D printing and 3D scanning. The buoyant atmosphere of one of the top universities in Latin America, located in chic Puerto Madero district (very well known among tourists traveling to Buenos Aires) was a great setting for the event, especially since lots of people became very enthused about printing their own projects for free at the 3D Lab. From Harry Potter tokens to glasses for children who can’t afford them, the dozens of 3D printed projects were a raging success among attendees. Trideo, one of the prominent local manufacturers of 3D printers was part of the event, showcasing some original eye-catching pieces. It’s co-founder, Nicolas Berenfeld, explained to 3DPrint.com why he also considers the country a very difficult place for a hardware business: “a few years back, there used to be a lot of developers of 3D printers in Argentina, however an increase in imports meant that many had to close their doors and transition to a different business model, mostly resellers of imported 3D printers. This approach is not entirely helpful for the development of 3D printing technology in the country since it doesn’t generate knowledge or add value to the industry.” Originally from Belgium, Berenfeld came to Argentina with a degree in business engineering, a strong belief that 3D printing can change the way we do things and a need to develop the technology in Latin America. His firm, Trideo, makes desktop and industrial 3D printers and offers professional 3D printing services for specific industry needs. Even though their industrial and professional printers are a big hit among many local small and medium firms, the entrepreneur had hoped Buenos Aires would become one of the great 3D printing hubs in Latin America.
During the highly publicized event, many healthcare professionals took the stage for an introduction into some of the most innovative medical uses for 3D printing. Rodrigo Salazar Gamarra, a dental surgeon and 3D printing innovator who creates facial prostheses with low-cost 3D technology, explained how his open-source, cost-effective methods are helping people everywhere, especially in poor communities where there is a great demand and need for fast cutting-edge healthcare solutions. Furthermore, one of the latest studies by the Renato Archer Information Technology Center in Brasil, where Salazar does a great deal of his work, indicated that the use of customized biomodels for complex maxillofacial operations can reduce surgical times by between 25% and 62%, reduce recovery times in hospital by 50% and have up to a total cost reduction of more than 24%. At the local level, scientists Diego Fridman, Pablo Luchetti, and Luciano Poggi, revealed a novel incision and closure surgical device made with 3D printing technology, INCLODE, which can be placed prior to a surgical incision and does not require stitches to close the wound. It’s bye bye scars once the device is approved for use in humans; currently, it’s in the pre-production stages. The device, which won the Israel Innovation Award in late 2018, consists of an adhesive sheet with a guide for the incision and allows its expansion and subsequent closure, with the help of a mechanical seal. “The doctor can work on the wound and once the work is done, the skin returns to its original place. What’s great about the gadget is that it reduces operating time, sewing a wound takes between 15 to 20 minutes, while INCLODE does the work in just a few seconds,” added Poggi. Also interested in how 3D printing advances medicine is the director of the Stratasys branch for the Caribbean and Latin America region, Juan Carlos Miralles. At Si3d, he highlighted how important it is for hospitals to have 3D printers, allowing doctors to save up to 60% in surgery time. According to the expert, a great example is the Las Condes Clinic, a private healthcare institute in Chile, which acquired a single-material Stratasys machine three years ago that prints with high precision and can develop accurate bone models. “Using personalized biomodels for surgery planning has proved to increase the probability of success by 90%, which is great news for the over 16,000 orthopedic spine surgeries every year. The technology used in the country’s healthcare system could help over 700,000 patients per year in the region,” he proposed. Miralles is mainly concerned with the healthcare sector, and he went on to explain how 3D printing could benefit medical students who face many challenges when trying to use cadavers during the first years of medical school practices. For years, medical schools everywhere have suggested that there is a shortage of cadavers, in part because of the rise in organ donations, and cadavers without their organs are not suitable for medical education. “Finding cadavers for medical practice is very difficult, and when university research labs finally get them, they need a specific room temperature and procedures to avoid decay. Medical students are also limited because they cannot choose a body that has undergone a specific disease or condition, so this is where 3D printing technology becomes extremely useful, being able to scan a patient’s tomography, reproduce it and study a specific case could ease professionals and students.” The Stratasys Latin America branch has been working closely with hospitals, universities, research institutions, and companies since 2013 to provide them with their best 3D printing technology. In Chile, quite a few institutions have teams with a high technological capacity to make precise biomodels, like the University of Santiago de Chile and hospitals like Clinica Las Condes and Orema Clinic. Currently, the Israel-based company has about a thousand machines in South America.
The event was a big success. With a majority of engineering students among the attendees, it was clear that once many of them get their degree, they plan to work with 3D printing technologies. Perhaps in a few years, Buenos Aires will standardize processes, scale up production and invest more in development of AM. Until then, experts suggest that we will see academia advance faster than the industry itself. And while manufacturers and enthusiasts are pushing for more government incentives for local companies, the Argentine Chamber of 3D Printing and Additive Manufacturing is trying to put together another 3D printing event in late July to further advance knowledge, share experiences and get the word out about what they are doing. It’s an uncertain future for many entrepreneurs who expect that an improved economy in coming years will benefit their companies, but until then they need to work together and collaborate to keep the 3D printing industry up and running. Printing via 3DPrint.com | The Voice of 3D Printing / Additive Manufacturing https://3dprint.com May 29, 2019 at 03:36AM Kyushu University: 4D Printing Magnetic Soft Actuators http://bit.ly/2WbLGdJ Japanese researchers from Kyushu University have created a 4D printer for magnetic soft actuators, outlining their research in the recently published paper, ‘Bio-Mimic Motion of 3D-Printed Gel Structures Dispersed with Magnetic Particles.’ Authors Hayato Shinoda, Seiji Azukizawa, Kazuki Maeda, and Fujio Tsumori designed new hardware for making 3D prints as well as 4D printing materials. The result of their work arrives in the form of actuators able to function as biomimetic examples with the potential to deform via a magnetic field—as magnetic anisotropy is ‘applied at each portion of printed structures.’ Each particle is magnetized before printing, causing it to rotate during curing.
There were two different types of biomimetic structures created: a worm-like structure, and an array of artificial cilia. Inspired by nature as scientists so often are, the researchers fabricated actuators able to contract continuously and move forward in a wave-like formation, then deforming. The researchers state that it could be demonstrated as a simple beam structure, separated into two areas.
The artificial cilia samples were created to imitate flowing ‘hair-like organisms,’ exhibiting a metachronal wave. The research team created four kinds of cilium with varying anisotropy.
To date, the team had not yet tested the structures for mechanical strength or other properties, but they were able to estimate residual flux density at about 3 mT, with magnetic flux density of 30 mass% ferrite material estimated at about 25 mT. Stating that finite element analysis would be a ‘powerful tool,’ the researchers explained that it would also be helpful for future studies to use a range of boundary conditions.
If 3D printing offers a multitude of innovations to the world, seemingly almost magical, 4D printing takes that one level further. With materials that morph and adapt to their environment, designers and engineers have created reconfigurable metamaterials, cellulose-based ink, and varying approaches with multiple materials.
