Video: Objet Eden260VS 3D Printer Perfect for Architects and Fine Feature Detail

Posted by Marcus Weddle on April 17, 2015 at 3:14 PM

Stratasys Fine Detail Interlaced 3D Printed BraceletThe stunning detail of PolyJet 3D printing technology is even better now with the new Objet Eden260VS printer. It retains the fine detail of 16-micron layers, but allows for delicate details and internal structures that simply weren't possible before.

The difference is SOLUBLE SUPPORT. 3D printed parts need support structure for overhangs and internal voids, with those supports being removed after the print completes. With PolyJet, this means a water jet will remove the supports, but this process can damage very thin details. That's no longer a problem with the use of soluble supports. The part goes into a gentle bath that dissolves away the supports--even from small internal cavaties--automatically.

This new printer is perfect for architects seeking the ultimate in fine-feature detail, both in the structure and even environmental features to make more realistic presentation models. For prototyping, designers have a powerful new tool that retains the smallest intricate details in the final printed part.

Watch the video for more information and examples of part files printed on the new Objet Eden260VS 3D printer. This printer offers several Vero colors with soluble support and a 10"x10"x8" build size. The printer can run other materials, such as rubber-like Tango, with traditional support.

CAD design firm partners with manufacturing contracting business

Posted by Peter Ivas on October 9, 2013 at 12:50 PM

Engineering and computer-aided design (CAD) software often go hand in hand. As an example of this relationship, the CAD drafting company CAD-Sourcing recently formed a partnership with Industrial Manufacturing and Installations (IMI), a millwright engineering and design contracting business.

CAD-Sourcing has been tasked with preparing all of the structural metal fabrication shop drawings that will be used by IMI in its latest project - modifying the Materials Testing Facility in Littleton, Colorado, for the defense and security company Lockheed Martin.

The project is likely to be lucrative for both IMI and CAD-Sourcing, since Lockheed Martin is widely known to be one of the premier manufacturers of advanced security products, including aerospace technologies. The Materials Testing Facility is a small branch of Lockheed's operation, which employs approximately 126,000 workers across the globe.

Bryan Luoma, the co-founder of CAD-Sourcing, expressed excitement about the potential of the partnership with IMI.

"We anticipate working with IMI, Inc. to provide detailed CAD shop drawings for the various metal fabrication and steel detailing requirements of the project in a quick and timely fashion," Luoma said.

The Bureau of Labor Statistics stated that the aerospace manufacturing industry employed a total of 503,900 wage and salary workers in 2008.

SolidWorks supports MIT initiative to educate young women about technology

Posted by Peter Ivas on October 9, 2013 at 12:49 PM

The future of industries like the computer-aided design (CAD) and STEM fields relies on an educated and creative base of employees. With regard to the field of advanced design technologies, the computer aided design (CAD) software developer SolidWorks is doing its part to promote the education of young women in these industries through its support of the Women's Technology Program at the Massachusetts Institute of Technology (MIT).

According to DesignNews, this program is being offered by the Cambridge, Massachusetts-based college to girls currently in their junior year of high school. The initiative targets a demographic that, perhaps unfairly, is not always associated with an avid interest in technology. SolidWorks is supplying free software to benefit the Women's Technology Program.

The news source reports that a total of 60 participants, from high schools all over the United States, will be picked from a much larger applicant pool to take advantage of the program's benefits. To be eligible, interested young women must be top-performing students in the subjects of science and mathematics.

During the program, which will take place over four weeks, participants will be able to learn about a number of subjects important to the field. These include mechanical engineering, computer science and electrical engineering.

MIT states that applications for the program will be available in November, open to students who are juniors in fall of 2011.

MIT combines 3D printing with sustainability concepts

Posted by Brad Edmond on October 9, 2013 at 12:48 PM

Massachusetts Institute of Technology (MIT) has done a great deal to earn its reputation as one of the premier colleges for highly advanced technology and engineering studies. It recently came up with a project that fused the principles of 3D printing, which has become prevalent in today's tech world, and sustainability by devising a 3D printer that works with recycled materials, according to Geek.

The news source reports that these printers use recycled plastic and other materials as a substitute for standing 3D printing materials. For example, the devices can use milk containers that have been broken up into smaller pieces to create the plastic necessary for their operation.

MIT's role in the development of this creation and other 3D printing projects can be seen as fitting, given the educational institution's status as the school where 3D printing was invented, nearly two decades ago.

These new printers are being used for a number of purposes. One of them is the creating of concrete-based designs with variable density at different points throughout the object.

The MIT Media Lab, where the printer was designed, is led by a dedicated research staff of 40 faculty members, senior researchers, scholars, research affiliates and visiting scientists.

3D printer used to create replicas of prehistoric fossils

Posted by Brad Edmond on October 9, 2013 at 12:48 PM

The applications for 3D printing in the fields of scientific and medical research are numerous. Continuing this trend, a high-end 3D printer is being used at the 3D Virtual and Solid Visualization Laboratory of Lehman College in New York City to create convincing reconstructions of animal fossils from prehistoric times.

According to Scientific American, a 3D printer in this laboratory can form simulated versions of ancient animal remains that never actually fossilized, using data of all that is known about a given creature. Lehman College staff can manipulate the reconstructed fossils in a variety of ways - changing their size and adjusting them so researchers can examine them according to their needs.

The news source reports that liquid blue plastic is used in the school's 3D printer to form the fossil replicas. The printer's advanced capabilities allow scientists to create, for example a highly detailed reconstruction of a prehistoric australopith primate. For particularly large projects, printing can take up to 48 hours.

Eric Delson, a paleoanthropologist and professor at Lehman College, is the founder of the 3D Virtual and Solid Visualization Laboratory, in addition to being co-director of the anthropology, biology and chemistry department at the school.

Medical scientists create artificial blood vessels through 3D printing

Posted by Brad Edmond on October 9, 2013 at 12:47 PM

The field of medical science is one of the areas in which 3D printing can be a considerably useful resource to researchers. Recently, a project at the Fraunhofer Institute for Interfacial Engineering and Biotechnology, in Stuttgart, Germany, used this technology in conjunction with the techniques of multi-photon polymerization to work toward creating artificial blood vessels.

According to Eureka Magazine, the methods employed allowed the scientists, led by Dr. Gunter Tovar, to envision the creation of detailed elastic structures with a 3D design plan. Although there is still a significant amount of work to be done, Fraunhofer Institute staff are hopeful about the prospects of this technique leading to the design of entirely synthetic organs with artificial blood vessels for supplying nutrients.

The news source reports that laser impulses were focused on the material, stimulating the molecules and facilitating their necessary cross-linking. Dr. Tovar expressed his positivity regarding the team's results.

"The individual techniques are already functioning and they are presently working in the test phase - the prototype for the combined system is being built," he said.

According to BBC News, this development could greatly advance efforts to create and engineer artificial tissue and organs to save the lives of patients in urgent need of transplants.

Educators employ 3D technology in various U.S. schools

Posted by Brad Edmond on October 9, 2013 at 12:47 PM

3D software and technology are already being employed in a wide variety of industrial fields, and new uses are continually emerging. In the last few years, teachers at schools throughout the U.S. have been adopting the technology in a variety of ways to enhance the learning experiences of their students.

According to the Wall Street Journal, after initial trial efforts with various 3D technologies proved fairly successful in a number of different schools, the technology began to be much more widely circulated. One of the most common applications of 3D is in the form of projectors that display visuals students can see as tangible objects, making the learning experience noticeably more interactive.

The news source reports that approximately 185,000 of these 3D projectors will be incorporated into American schools throughout the remainder of the year, at grade levels ranging from kindergarten to 12 as well as at several colleges.

A number of studies comparing the educational value of 3D projection against its 2D counterpart found that test scores increased significantly more for students taught with the former method rather than the latter.

3D projection is widely used in engineering, which as of 2008 took up 1.6 million jobs in the U.S., according to the Bureau of Labor Statistics.

Canadian start-up offers desktop 3D printer for $116

Posted by Peter Ivas on October 9, 2013 at 12:47 PM

For the members of the maker movement, the wide-scale adoption of 3D printing and rapid prototyping techniques has always been a question of not if but when. Over the last few months, there has been a flurry of activity within the industry itself, ranging from the merging of leading companies within the sector to innovations that have brought the technology to mainstream media attention.

While the market remains relatively small in terms of revenue earned, one of the concerns has always been that the price of desktop 3D printers themselves may prove to be a stumbling block in terms of wider consumer acceptance.

However, an over-funded project on popular crowdfunding website Kickstarter could be the answer. According to CNet, a Canadian start-up is offering backers the chance to purchase a 3D printer for $116, a price threshold that would certainly make it an affordable option for interested consumers and one that has already seen the original research and development funding goal of $50,000 exceeded by over $450,000 in less than a week.

3D printing innovation
What allegedly sets this cost-effective device apart from its competition is the fact that it relies on an innovative combination of photo-lithographic printing and a salt-water based drip process to create an object from an audio wave or sound file. According to the news source, the "Peachy Printer" uses a controlled beam of light to turn light-sensitive resin into 3D printed objects, with the installed software turning a CAD 3D file into a format that can be listened to by the printer, which then allows the drip feed to calculate the depth level required.

What this means in simple terms is that the Peachy Printer - which it should be noted is still in the prototype stage and unlikely to be shipped much before summer 2014 - uses less materials then conventional printers and, ultimately, allows even those with limited CAD skills to create an item. One drawback is that the light-sensitive resin is of a slightly lower quality than other 3D printing materials on the market, but for those who want to experiment with the technique at a low financial commitment, it could be an intriguing entry point.

"We didn't actually market it," said Rylan Greyston, the 28-year-old inventor of the 3D printer, in an interview with Canadian radio show News Talk 980. "We just sort of posted it, and it was shocking that it just sort of spread like wildfire on its own. I think it'll perform competitively with these $3500 versions. I've just made some groundbreaking changes to how you can make a 3D printer."
