Fourth Industrial Revolution technology in ‘Sierra Leone’

Posted on

According to the President Julius Maada Bio,” the West African country of Sierra Leone used a 3D printer to create a map of Sierra Leone with the distribution of the number of girls not attending primary schools across the country. The idea evolved over lunch at State House where senior government officials were discussing the status of education within the country.”
According to the head of UK’s Department of Foreign International Development Mary Hunt, “the fact you can pick it up and turn it around to see different aspects of the map makes you feel like you are there – in Kenema, Kabala, or Bonthe – seeing the challenges in peoples lives and what needs to change. I was so drawn to its clarity and potential I had to ask the President if I could take it with me I wanted to share it with others.”
This is the ‘Fourth Industrial Revolution technology’.

3D printed resistive soft sensors

Posted on Updated on

According to related publications from Shih B., Christianson C., Gillespie K., Lee S., Mayeda J., Huo Z., Tolley M. T. (2019), “Design considerations for 3D printed, soft, multi-material resistive sensors for soft robotics. Frontiers in Robotics and AISubmersible robots are finding ever-increasing uses in search and rescue, environmental monitoring, and defense applications. Artificial muscles made out of dielectric elastomer actuators (DEAs) provide an attractive choice for driving submersible robotics based on their high energy density, lightweight, and efficiency. One challenge for most DEAs is that that they require conductive electrodes that are made out of materials that are challenging to the pattern, opaque, and/or add stiffness to the devices.”

Fab lab hub for 3D Printing

Posted on Updated on

The brightest minds in DigiFab learning to expand your interaction with innovative education and workforce training communities!

According to Fab Lab Hub founder Sarah Boisvert who organizes the conference, “DigiFabCon is thrilled to be in Pittsburgh with its vibrant additive manufacturing community and engaged STEM ecosystem. America Makes recognizes that a trained workforce is essential to the adoption of new disruptive technologies and their new programs that include certifications and Digital Badges are key to Industry 4.0’s success”.

NASA’s Centennial Challenges

Posted on Updated on

According to Monsi Roman, program manager for NASA’s Centennial Challenges and Lex Akers, dean of Bradley’s Caterpillar College of Engineering and Technology,”The final milestone of this competition is a culmination of extremely hard work by bright, inventive minds who are helping us advance the technologies we need for a sustainable human presence on the Moon, and then on Mars. We celebrate their vision, dedication, and innovation in developing concepts that will not only further NASA’s deep-space goals, but also provide viable housing solutions right here on Earth.
It is an impressive achievement for these two teams to demonstrate this disruptive and terrific 3D-printing technology at such a large scale. By teaming up with NASA and Caterpillar, we are proud to bring these teams together in an environment where they can innovate, create and challenge our vision of what’s possible. Congratulations to both teams for their accomplishments.”

3D Printing News Alert(3D print metamaterials with novel optical properties)

Posted on Updated on

3D print metamaterials with novel optical properties. The geometry of a moth’s eye provides inspiration for a 3D printed antenna that absorbs specific microwave frequencies from any direction.
According to Sameer Sonkusale, professor of electrical and computer engineering and Aydin Sadeqi, a graduate student in Sankusale’s lab at Tufts University’s School of Engineering who heads the Nano Lab at Tufts and is the corresponding author of the study, “The ability to consolidate functions using metamaterials could be incredibly useful. It’s possible that we could use these materials to reduce the size of spectrometers and other optical measuring devices so they can be designed for portable field study.
The full potential of 3D printing for MEGOs has not yet been realized. There is much more we can do with the current technology, and vast potential as 3D printing inevitably evolves”.

SpaceX 3D Printed chamber

Posted on Updated on

According to the NASA and SpaceX teams, “Ensuring that our systems meet rigorous safety standards and detecting anomalies like this prior to flight are the main reasons why we test. The SpaceX spokesperson said. “Our teams are investigating and working closely with our NASA partners.
A dispatcher at the Brevard County Emergency Operations Center said local officials were aware of the SpaceX accident at Cape Canaveral but were not aware of any risk to the public.
The SuperDraco thrusters are designed to push the Crew Dragon spacecraft away from a failing rocket during launch. Each engine has a 3D-printed chamber and can produce up to 16,000 pounds of thrust, with the ability to restart multiple times”.

Photogrammetry software for 3D Printing

Posted on Updated on

Photogrammetry software for 3D Printing. According to Sculpteo, “3D scanning could be useful for various applications. It can be used to get a viable 3D model and make the most of the 3D printing technology using an online 3D printing service such as Sculpteo. But having a great 3D design is also an amazing tool for visualization.

Photogrammetry is useful for topographic mapping, architecture, engineering, or even geology! There are a lot of software tools dedicated to aerial photos, photogrammetry is really useful for geographical use. For instance, archeologists are also using it to create plans for complex and remote sites”.

Some of the best free photogrammetry software


Agisoft PhotoScan
3DF Zephyr Free
Colmap
Visual SFM

Paid software

Context Capture
Reality Capture
3DF ZEPHYR
Autodesk ReCap Pro
Inpho
iWitnessPRO
Pix4Dmapper
Photomodeler Pro 5

According to some comments,
“It is still easier to 3D sculpt from scratch than to scan using photogrammetry in some cases. As some 3D sculpting will be needed when cleaning and patching anyway.
Zephyr offers a function where you can upload an mp4 / video file. Pretty cool feature. It does all the things in the video but in one tool. Much easier to use as well. Free is capped at 50 photos.
COLMAP is sooo cool and cheaper smarter alternatives.
Autodesk Recap is paid and limited (I heard that there is a limit number of the image you can upload to their cloud – and it’s the web-based application so if you don’t have internet, you can’t do anything).

Some people like VisualSFM and best software to do this is still pix4d. These are also powerful and free, it uses additional CSM tools you need to install for as dense reconstruction; it works great with different image sources.
3D Creator from Sony Xperia is really easy and awesome and avoid a lot of steps compared to this traditional method.
Agisoft Photoscan is far better than Colmap+ Meshlab.
For some problems, we can get suggestions from the comments.
I am trying to get into 3D computer modeling, and I want to model this new military helicopter for a video game (ARMA 3).
The problem is the chopper is extremely new and there are very few pics of it out there, so the background in each photo is always different. would these cause problems with modeling.
If you want to get some pretty amazing results using the basic version of Agisoft Photoscan ($179 US for a commercial license) and some very good results with VisualSFM (free for non-commercial use).
You can rotate the object as long as the background is in solid color. There are several solutions on the internet, mostly by programming Arduino to rotate turntable with the object, then sending remote shutter signal to the camera. This whole process can be automated with very good results:)

3D Printing News Alert(New space for a 3D printing company in the Houston)

Posted on Updated on

According to 3D printing company re 3D’s co-founder, Matthew Fiedler, “You now have access to large-scale 3D printers. The Houston company opened its community space in its factory located next to the NASA Johnson Space Center in southeast Houston.

The company makes an affordable and customizable 3D printer, called the Gigabot, and has clients across industries in over 50 countries.
A hidden scientific gem resides at Southwestern Adventist University: more than 20,000 dinosaur bones and precious prehistoric data. In the university’s Dinosaur Museum and Research Center, a Gigabot is being used to 3D print bones.
Greneker is a leader in the world of custom mannequin design and manufacturing, and they’re staying competitive in the fast-moving apparel marketplace with the help of 3D printing. Their Los Angeles office has a dedicated 3D printer room which is home to four Gigabots”.
