Three Guinness World Records related to the largest 3D printer

Posted on Updated on

According to Sen. Susan Collins, “I was delighted to join UMaine’s celebration unveiling the world’s largest 3D printer and largest 3D-printed object. The future of the [UMaine] Composites Center is bright, thanks to the excellent working relationship between UMaine, Oak Ridge National Laboratory and many other federal agencies, which will support next-generation, large-scale additive manufacturing with biobased thermoplastics. As a senior member of the Senate Appropriations Committee, I helped secure $20 million for this exciting collaboration, and an additional $20 million is included in the committee-approved energy funding bill. By working together, UMaine and Oak Ridge will strengthen environmentally responsible advanced manufacturing throughout America, as well as the forest-products industry in Maine.”

According to Sen. Angus King, “Maine is the most forested state in the nation, and now we have a 3D printer big enough to make use of this bountiful resource. Today marks the latest innovative investment in Maine’s forest economy, which will serve to increase sustainability, advance the future of biobased manufacturing and diversify our forest products industry. This is a huge opportunity for the state of Maine, and I’m grateful to everyone — especially the the University of Maine and the FOR/Maine initiative — for their work to make this day a reality.”

According to U.S. Rep. Jared Golden, “As we saw today, the University of Maine Composites Center does award-winning, cutting-edge research that makes Maine proud and will bring jobs to our state. Their work, like the boat and 3D printer we’re here to see, has impressive potential to change how we make things out of all sorts of materials — including Maine wood fiber. Today is about three Guinness World Records, but it’s also about celebrating the innovation that will help protect and create good-paying Maine jobs in forest products and manufacturing.”

According to Moe Khaleel, associate laboratory director for Energy and Environmental Sciences at ORNL, “This is an exciting achievement in our partnership with the University of Maine. This new equipment will accelerate application and integration of our fundamental materials science, plant genomics and manufacturing research to the development of new sustainable bioderived composites, creating economic opportunity for Maine’s forest products industry and the nation.”

Recycled Material Extrusion Additive Manufacturing

Posted on Updated on

Recycled Cellulose Polypropylene Composite Feedstocks for Material Extrusion Additive Manufacturing. According to ACS publications,” Many types of consumer-grade packaging can be used in material extrusion additive manufacturing processes, providing a high-value output for waste plastics. However, many of these plastics have reduced mechanical properties and increased warpage/shrinkage compared to those commonly used in three-dimensional (3D) printing. Recycled polypropylene/waste paper, cardboard, and wood flour composites were made using a solid-state shear pulverization process.”

Hasbro To Eliminate Plastic Packaging

Posted on Updated on

According to Hasbro, “one of the world’s largest toy manufacturers, has stepped up its sustainability game and is phasing out all plastics used to package its toys and games by the end of 2022. phasing out plastic from new product packaging, including plastic elements like polybags, elastic bands, shrink wrap, window sheets, and blister packs.3D printed toy designers should ramp up their knowledge about alternative sustainable materials.”

Hasbro To Eliminate Plastic Packaging

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.

 

3D printing to build titanium bikes

Posted on Updated on

3D printing to build titanium bikes. According to The folks at Moots,” have been building gravel-focused bikes since 1981. In 1991, Moots went all-in on titanium frames and never looked back. Since then the methods for the building have evolved. They now include 3D-printed titanium parts, which Moots uses to push its frame design to new limits.”

I love learning about small companies that are still significantly motivated by pride.

While their products will, by necessity, be more expensive, the experience of designing, constructing and owning something like that will almost certainly be more satisfying and meaningful, even if each of those steps takes longer to achieve.

The days of easy come, easy go, are ruining the planet and have already taken any sort of pride out of the process. I for one, congratulate Moots for doing their own work, and doing it with obvious care.

Hopefully, we can see more videos like this one from real manufacturers and not just business models that outsource. Thanks for the excellent video!

Anodizing explanation was slightly off, it’s not really about the shape of crystals. The different colours in this case are achieved by building up a very thin oxide layer. As light goes through the oxide layer and reflected by the material it gets bent slightly, just like when you look into water. Because the oxide layer is about the same thickness as the wavelengths of visible light, you get interference on certain wavelengths. Depending the thickness of the oxide layer, different wavelengths are affected by that interference so you get different colours.

Absolutely brilliant. would love nothing more than a costumized titanium bike! The fact that they’ve kept up with time and put disc brakes, more clearance for wider tyres is just fantastic. Can’t imagine a more enjoyable bike than those.
