Cool solar-cell gantry… if it could be modified to be housed in a weather proof enclosure… and sun position info sent to the microcontroller. Just thinking out aloud here…

3D printed “Star Trek Enterprise”

Posted on Updated on

According to Glenn and T’Pol, who also serves as the University of Houston-Victoria’s provost and vice president of academic affairs, received degrees in electrical engineering from the University of Maryland at College Park and Johns Hopkins University, “The startup world’s 3D printing craze comes to Victoria. A glass of cold water materializes at a simple command from T’Pol, a Vulcan who serves on the spaceship Enterprise, in a clip from the early 2000s series “Star Trek Enterprise.”
I saw a similar device on a Tarkalean vessel,” It was capable of replicating almost any inanimate object.
If we had one of these in engineering, we could make all the spare parts we need notes Trip Tucker, another character in the series.”

According to German RepRap, “create future-oriented technologies and implement them in the design and production of our 3D printers. Since 2010 we have been developing our X-Series 3D Printers based on Fused Filament Fabrication (FFF) technology. The special feature of all printers is the Open Source Platform, which makes it possible to use a variety of materials for printing. New consumables are constantly being tested and added to our product range. The Liquid Additive Manufacturing (LAM) process, liquids such as silicone rubber can also be processed.”

3D printed Terran 1

Posted on Updated on

According to Relativity Space is a private American aerospace manufacturer company headquartered in Los Angeles, California, “Relativity Space was founded on the idea that Blue Origin and SpaceX were not doing enough to use 3D printing as part of rocket manufacturing. Relativity plans to 3D print an entire launch vehicle they call Terran 1. The extensive use of 3D printing has allowed the company to iterate designs quickly, use less tooling and human labor. In March 2018, Relativity Space signed a 20-year lease at the John C. Stennis Space Center, a NASA rocket testing facility, to test engine components and eventually test full-scale Aeon 1 rocket engines.
The company says it will launch its first rocket named Terran 1 from the site in 2020. Relativity plans to start commercial launch service by early 2021.”

Achieve true 3D printing with non planar slicing

Posted on Updated on

According to Teaching Tech,” This is the most interesting thing I’ve done with my 3D printer in some time. Instead of printing in a series of 2D planes stacked up to form a 3D shape (2.5D), this non planar technique creates geometry with true 3D tool paths that can eliminate the steps often seen on shallow surfaces. Based on the amazing Masters Thesis of Daniel Ahlers and the University of Hamburg, this development can be tried yourself if you are willing to put in some time to setting it up.”

Hi everyone, some updates:
– A bunch of people pointed out that Windows 10 now has an embedded Linux environment. I installed this and went through the process again. I had a couple of errors and had to manually install missing cpan libraries via the command line. Slic3r did successfully compiled, but only runs via command line rather than with a graphical user interface as seen in this video. I’m sure there’s a way to add even more modules to get the GUI working, but it’s beyond my knowledge.
– Some people also mentioned setting up a dual boot configuration. This is another great suggestion but I need to have my Windows PC on at all times to keep my video production going, so not suitable for me.
– There have been some viewers pointing me towards ‘air brush’ nozzles. I’ve ordered a set, they look ideal for this technique.

Windows subsystem for Linux 2.0 is much better then 1.0. Should be in the windows 10 1909 release.

I have this working with WSL under Windows 10 and have used VcXsrv as the Xserver. It also allows pretty easy access between filesystems for loading STLs and writing back the gcode.

@grandaspanna Yes. Most people with 3D printers know about gcode and STLs. They know how to calibrate their printers and make it print. But the software is somewhat mysterious, as are the effects one little change to a parameter in the slicer.
But what I think would help the most is a simple, already compiled executable program that would run and turn a traditional printer into a “true” 3D printer, using the methods discussed in this video.
I never even thought that my printer was a “2-1/2 D” printer until I watched this video. But now it makes so much more sense to do it this way. In fact, it makes sense to go one step further and make printers with five axes, so that the print nozzle is always perpendicular to the extrusion. When we get to that point, then we can start work on finer nozzles and plastic that extrudes with more granularity.
I do believe that the “big boys” who are printing airplane parts on demand have the right idea but that hasn’t filtered down to the hobbyists like me yet.

This is awesome. No idea why I’m watching this as I don’t have a 3D printer, but it’s awesome.

I had recently been thinking of this kind of technique. I had thought that this technique would be more easily implemented with a delta based 3D printer. So that the print head could be tilted.

you cant tilt the nozzle on a delta. the nozzle will always be parallel to the printbed

Tim Milgart

@Gerhard Wilkens Yes, but it would be logically more easily to do it on a delta based 3d printer. (As I see it, but i’m only a engineer, so everything can be done in my optic).

it is very much doable, but is highly dependent on the Delta Design, my current delta prototype will actually do this, once i get the new board in, and some Titan Extruder spares. Cause the hot end hangs below the effector plate, with the magnetic arms on my printer giving a good range of movement the code can be adjusted to tilt the head. But it depends if slic3r can be adjusted to generate G-Code like this

That’s cool, but too much difficult work on software side.
I think it could really take of if CURA would make experimantal mode with it.
Then people would just need to remove the fan shroud, on stock Ender 3 that’s actually easy,

This looks amazing! I will have to try it out very soon. Clean the Z screw and modify the CR10S hotend to have a part cooling fan and a decent head cooling fan…will see what I can do and if I manage it I will share it on Thingiverse.

I mentioned this on the other video, but the next logical steps for non-planar are hot ends that have steeper angles, taller height to width ratio. Basically, with a steeper angled nozzle, it could fit into tighter curves. This also needs an entirely different cooling system, though, but that shouldn’t be too difficult to develop.
Non-planar also nicely extends into 5axis printing, which should be the next step of developments for the future of FDM.

According to Suhasa Kodandaramaiah, Ph.D., a co-author of the study and University of Minnesota Benjamin Mayhugh Assistant Professor of Mechanical Engineering in the College of Science and Engineering “What we are trying to do is to see if we can visualize and interact with large parts of the mouse brain surface, called the cortex, over long periods of time. This will give us new information about how the human brain works. This technology allows us to see most of the cortex in action with unprecedented control and precision while stimulating certain parts of the brain.”

According to Kodandaramaiah and Ebner, the research team was led by fourth-year mechanical engineering Ph.D. student Leila Ghanbari. The research team included several post-doctoral associates, graduate students and undergraduate students including Russell E. Carter (neuroscience), Matthew L. Rynes (biomedical engineering), Judith Dominguez (mechanical engineering), Gang Chen (neuroscience), Anant Naik (biomedical engineering), Jia Hu (biomedical engineering), Lenora Haltom (mechanical engineering), Nahom Mossazghi (neuroscience), Madelyn M. Gray (neuroscience) and Sarah L. West (neuroscience). The team also included partners at the University of Wisconsin including researcher Kevin W. Eliceiri and graduate student Md Abdul Kader Sagar, “This new device allows us to look at the brain activity at the smallest level zooming in on specific neurons while getting a big-picture view of a large part of the brain surface over time. Developing the device and showing that it works is just the beginning of what we will be able to do to advance brain research.”

U.S. Air Force – The first approved project was printed on the Stratasys F900

Posted on Updated on

According to Travis release,” The first approved project was printed on the Stratasys F900, can print parts with dimensions up to 36 inches x 24 inches x 36 inches made of Ultem 9085, a specialized plastic known for its extra flexibility, density and strength. The 60th Maintenance Squadron at Travis AFB, Calif., is the Air Force’s first-ever field unit to be equipped with a Federal Aviation Administration- and USAF-certified 3D printer capable of producing aircraft parts. Typically, parts that don’t keep the aircraft from performing their mission don’t have as high as a priority for replacement.”
According to MSgt. John Higgs, the squadron’s metals technology section chief, in the release, “We already have a list from the Air Force level to help them print and to backfill some supplies. This will ensure other bases can replace items sooner than expected with our help.”

Why Investments in 2020 Additive Manufacturing?

Why Investments in 2020 Additive Manufacturing?
Are Likely to Increase in 2020.
According to ETFs consumers initially saw 3D printers as a “factory in every home, but they soon came to realize that the items they produced weren’t functional. As the hype fizzled out, new fears emerged in the manufacturing segment, and some companies using 3D printers saw year-over-year declines in their revenue. The rise and fall of additive manufacturing took place over a few short years, but that wasn’t the end of the story.”

According to TriLine“The share of renewables in meeting global energy demand is expected to grow by one-fifth in the next five years to reach 12.4% in 20232. RENW aims to offer long-term exposure to the growing future of energy,”

Additive manufacturing is on an upward trajectory as of late. This resurgence is due to the fact that the list of possible 3D-printable materials has more than doubled in the last five years.”

According to Dean Franks, the head of global sales at the additive manufacturing company, Autodesk, “believes that consumer products, industrial machinery, automotive and tooling applications are the growth opportunities for additive manufacturing. He believes that these industries will start to grow as the more established aerospace, medical and dental markets continue to grow.”
According to Bertrand Humel van der Lee, the Chief Customer Operations Officer at EOS, “predicts that 3D printing within healthcare will flourish because there is an increase in demand for personalized healthcare, treatments, and medical devices.”
According to the Morningstar North America Renewable Energy Index, which is designed, “to provide exposure to companies that operate across the full renewable energy supply chain, including renewable energy innovators, suppliers, adopters, and end-users.”
According to TriLine Index Solutions, the index and ETF development arm of Boone Pickens Capital Fund Advisors.”
