To the moon and beyond!

NASA is wanting to get to Mars and they need the publics’ help. They recently launched their latest Centennial Challenge and the goal this year is devise a way to construct a habitable structure on the planet Mars using 3D-printed material. $2 million in prize money is up for grabs so there will be no shortage of contestants. This is the 3rd phase of an on-going contest with previous years focused on architectural concepts and material components. This phase will be an actual on-site competition with the contestants being asked to come up with an autonomous adaptive manufacturing process using indigenous materials. In short, NASA wants to be sure when we do get humans up there someday, they will be able to construct shelters quickly using the planet’s native resources instead of having to rely on constant resupplies from Earth (examples of such material being clay, sand or gravel).

While it has been 48 years since man first set foot on the moon, space exploration is experiencing a mini-renaissance with the rise of private companies looking to strike gold in the darkest reaches of the universe, such examples being Elon Musk and SpaceX or Richard Branson’s Virgin Galactic which hopes to be a charter for future space tourists. NASA’s call for private aid is fueling the birth of a whole new industry and 3D printing is allowing small and medium-sized companies to construct rockets, satellites, spacecraft and more that would have never been possible outside of a giant government lab with thousands of engineers and billions in R&D.

Another historic milestone will be made this week as a 3D printed satellite will be launched into space by NASA thanks to the work of students at Northwest Nazarene University (NNU) and Caldwell High School in Idaho. This satellite will be carrying multiple 3D printing materials;  ABS, PLA, nylon, and PEI/PC Ultem. These materials will be delivered to the International Space Station so the scientists and astronauts on board can test their resiliency and usefulness in space for future missions.

The rapid advancement in 3D printing and aerospace really proves that one small step can turn into one giant leap for mankind.

WYSIWYG….WYSI What???

Posted by on Oct 31, 2017 in 3D Printing, 3D Technology Blog | 0 comments

WYSIWYG….WYSI What???

“WYSIWYG” pronounced wizēˌwiɡ, stands for What You See Is What You Get. This is a term that was once very popular in the graphic arts printing industry, at least in the early days of desktop publishing. It was a term often used with customers to explain why chunky or rough looking text and or graphics, sometimes referred to as raster disasters, displaying on their screen would look just like that on the printed page. It was a way of proofing work to avoiding unexpected surprises in the end product.

 I find today in the 3D prototyping industry that this is still true. Often times the 3D printer (any brand name) or printing process gets the blame for poorly printed results. We hear this all the time from customers complaining about the quality they received from another vendor.  And yes there is much that can be said about printer calibrations and how the lack or neglect thereof can and will produce poorly printed parts even with the best saved files. Yet often we find the files have been saved or exported, out of the CAD program of choice, in the .STL or .OBJ format for 3D printing in low resolution, usually the default settings, causing cylinders and curves to appear rough and faceted. While this generates a small file size to send to your vendor or printer the results are usually less than desirable. Therefore, we highly recommend to our customer to install a one of several free .STL viewers to inspect your part(s) before sending them to be printed. Many of the hobbyist to high end 3D printers will produce what is being sent to it, within the tolerances of the given printer. In short most 3D printers can produce better parts if they are given better files to work with. You can find a guide on how to save/export in a .STL format from the most popular 3D CAD programs by clicking here.

This was the original file sent. Notice the faceting on the curved surfaces.

This was exported at a higher resolution and will result in a much smoother 3D print.

Graphene in 3D Printing: Ten Times the Strength of Steel and Only a Fraction of the Weight

Posted by on Oct 23, 2017 in 3D Printing, 3D Technology Blog | 0 comments

Graphene is an elemental carbon made of one flat sheet of atoms that are arranged in a repeating hexagonal lattice. It is only one atom thick, which makes it weak and flimsy in its 2D form. Researchers at MIT were able to take the flimsy 2D material and turn it into 3D structures using a high resolution multi-material printer; making the graphene geometry incredibly strong—ten times the strength of steel but only a fraction of the weight. The material is electrically conductive and can be nearly transparent.

This article compares how folding a sheet of paper increases its strength the more and more you fold it; just as creating 3D printed objects with layers of graphene increases its ability to support substantial weight. MIT combined heat and pressure to compress small flakes of graphene to produce strong structures. The shapes had an enormous surface area in proportion to their own volume and were very strong.

Markus Buehler, head of MIT’s Department of Civil and Environmental

Engineering (CEE), said that it’s not the material that’s the dominant discovery; it’s the geometry. He says that you could replace graphene material with any other mareial like polymers or metals or anything and use the same geometry to make that object have extreme strength and light weight.

Tethon 3D Ceramic Resins for Use in SLA and DLP 3D Printers

The days of 3D printing solely with plastics are far behind us. Not only can 3D printing be done using silver, titanium, steel, and waxes—we can also print using ceramic powders for binder jetting and stereolithography (SLA) processes. Tethon 3D was the first company to develop and commercialize ceramic powders as 3D printing material, and they are now using it to create high quality durable 3D printed ceramics.

The company is built around a business that has a strong background in ceramics. They began at the Kaneko Experimental  Studio in Omaha, Nebraska, founded by a ceramic sculptor named Jun Kaneko. Their SLA materials are ceramic glass and ceramic: Vitrolite and Porcelite. These can be used for objects that need the same properties as ceramic; heat shock tolerance, heat insulating, anti-corrosive, chemically resistant, controllable porosity, and other factors. It’s used in automotive, jewelry, manufacturing, aerospace, architecture and healthcare.

Porcelite is an alumina-based ceramic resin. Once it’s printed it becomes a polymer clay composite material and after it’s sintered it becomes porcelain with a temperature stability of 2,500 degrees Fahrenheit. Vitrolite is a silica-based glass ceramic resin that’s sintered at a lower temperature. It’s very dense and very smooth, with a milky white color. The two materials could be used on many SLA and DLP printers, and are compatible with both industrial and desktop use.

3D Printed Human Spine Replica Can Prepare Surgeons for Spinal Surgery

3D printing is being used more and more in the medical industry and is helping doctors and surgeons to prepare for procedures with realistic replicas of organ structures and bones by using 3D printed parts. Nottingham Trent University researchers are 3D printing replicas of human spines for this exact purpose.

By printing realistic vertebrates and spinal discs they’re allowing students and trainees to learn in a safe and calm environment while still simulating a life-like procedure. This could improve the outcomes for real patients undergoing spinal surgeries.

Inside of the vertebrate is a softer cancellous bone, which the researchers replicated with soft foam. The outside is a harder cortical bone which was printed using a polylactic acid (PLA) material. The spinal discs on the replica were made of silicone.

The researchers are able to print spines with specific problems like scoliosis and use those to practice on. They can also use it to practice procedures such as laminectomies, trapped nerve relief, and the removal of bone structures.

It’s very important for surgeons to be thoroughly prepared before going into spinal surgery, because one small mistake in a real surgery could be catastrophic for the patient. In the future the researchers plan to print bones with varying strengths to help prepare surgeons for operating on people with diseases like osteoporosis.

Tinkerfest 2017 a Success

               The crew at ProImage 3D had a blast last Saturday at Tinkerfest hosted by the Science Museum Oklahoma in OKC. We would like to thank the staff at the museum for inviting us to participate in the event and allowing us to help teach others about 3D printing and scanning. The turnout exceeded our expectations and we were blown away by all of the fun and exciting things happening at the event, including rocket launches and cardboard cities.

                We were able to bring our fused deposition modeling (FDM) printer with us and print off a few tugboats to hand out to the kids, as well as a few bat bookmarks. We truly enjoyed seeing how fascinated everyone was with what we were doing– parents and children alike! We hope to be back next year with even more activities for everyone to participate in and we’d like to thank everyone that came out to see us!

Self-Assembling “Patchy Particles” Could Revolutionize 3D Printing

Self-Assembling “Patchy Particles” Could Revolutionize 3D Printing

                Molecular self-assembly is a process when a disordered system of molecules forms an organized arrangement without help from an outside source.  Self-assembly is also used in proteins to assemble themselves into virus capsids and phases associated with diseases; the process is driven by thermodynamic and kinetic factors. Scientists have figured out a way to mimic this process through colloidal fusion of particles known as patchy particles, making 3D printing at a molecular level a possibility.

                Created by a team of scientists at New York University (NYU), patchy particles are 10-100 times smaller than a human cell. They are made up of smaller triangular particles that come together like play dough to form a sphere through a process called colloidal fusion; these spheres can then go on to create even more complex structures.

This could allow us to print on an even smaller scale, bringing us closer to 3D printing nanotechnology. According to Stefano Saccana, assistant professor of chemistry at NYU, “You could print a car that is a fraction of a millimeter and that could someday actually run!”

Science Robotics Uses 3D Printing and Biorobotics for Underwater Exploration

Science Robotics Uses 3D Printing and Biorobotics for Underwater Exploration

          The Hadal zone lies at an eerie 20,000 to 36,000 feet below the sea in the Mariana Trench. A combination of water density, intense pressure and darkness make it difficult for scientists to capture data that deep in the ocean. Some living creatures such as sea anemones have adapted to these conditions and are able to survive using soft bodies and pedal discs to give them a strong grip that allows them to attach to rocks and withstand strong currents. The remora suckerfish is similar in that it has a highly modified dorsal fin that forms an adhesive disc, one of the most impressive adaptations within the vertebrates.

          Science Robotics has designed a multimaterial biomimetric remora disc using 3D printing and soft robotics. This underwater robot is capable of strong adhesion and hitchhiking on smooth and rough surfaces, including shark skin. They used varieties of flexible and rigid material on an Objet Connex 500 C3 3D printer from Stratasys, and used Solidworks to create the CAD file. This could allow for new ways of exploration and understanding of marine wildlife, even in the deepest and darkest parts of the ocean.

T3D Launches a Kickstarter Campaign for 3D Printer Powered by Smart Phones

 

          T3D, a startup company founded in the National Taiwan University of Science and Technology has launched a Kickstarter campaign for a mobile 3D printer powered by the light of a smart phone or tablet. The printer is able to print without a protective cover or glass because of the special high sensitivity resin created by T3D; allowing viewers to watch the printer pull 3D printed objects right out of the resin bath.

          A smart phone or tablet goes underneath the tray of resin and the printer uses the light to cure the light-polymerized resin. The smart phone/ tablet acts as a light projector found in most typical SLA machines. The printer is capable of printing at 20 seconds per layer with a layer thickness of 100 microns, on a build tray that’s 16 x 7.6 x 8.5 cm. Thanks to that portable size and its ability to be controlled by mobile devices, it’s perfect for traveling and printing on-the-go.
