Do you have questions? Ask away and I’ll do a follow up video with James Anderson and get them answered for you!
I have a question. The finished product looks so smooth. What do they do to smooth out the layer lines from those giant layer beads?
Have they considered embedding structural reinforcements (carbon fiber panels, strips, or tubing), flanges, nuts, etc. (AKA: Vitamins), into the prints while they are printing to increase strength, function, and rigidity, while reducing weight and print time?
How does the material being fed to and from the extruder differ from small scale printing? Any details on the printhead (extruder, hotend, nozzle) would be great.
He mentioned near the beginning that the machine can feed up to 500lbs an hour, but the current extruder only feeds 125lbs an hour. Is it a limit on heating? If the limit is heating, and not in the motion system could you do a smaller nozzle at a faster speed and cut back on some of the negatives mentioned for a large format printer? I'd love to see a video of you extruding the CF-ABS too if you are making it yourselves.
What's the power consumption?
Worlds largest benchy boat?
Got my upvote!
Maybe big enough to sit in?!
I was hoping
yes!! BIG BENCHY FTW
Butters Stotch that’s awesome
Yeah I was hoping that they meant benchy when they said boat.
With Maine being able to support so many traditional boat builders and boat building schools it’s very interesting to see the effort being put into the high production side
4:35 😭😭
The audience donated their hair for the boat(LOL).
Lol
Couldn't you share the files for this print so there would be small siblings for this boat around the world ?
Scaled down the walls would probably be too thin for most common printers to print but if they made the walls thicker I’d want it
@@drewsnyder1436 activate "print thin walls" in cura
It’s the layer time that’s tricky. Big beads like that need some cooling before the next layer comes around. And overhangs … tricky!
The best thing is people just walking around a giant extruder
That's amazing! Thanks for sharing and congratulations to the team there! Changing manufacturing for the better for my kids futures! Awesome!
Precisely the content I was looking for! Very nice, I really enjoyed that.
Thanks! Subscribe and check my other videos!
Thank you so much for sharing‼️ this is exciting‼️
The extruder head must be specially designed for that 45% printing.....really smart engineering to overcome the physical limitation.
Could you do a video on the design process for this boat? For example, did they print a model first or did they just go right to the full-size version? Also, did they do force calculations on the model and structural analysis before printing? Do they plan on stress testing the finished boat to see how well it holds up?
Added to my list of questions for James on a follow up
@@WhereNerdyisCool Are you in Maine? Do you go to U of Maine?
John Tarbox I work at the University of Maine Advanced Structures and Composites Center
I'm betting that this is mostly for answering those questions and more. You would need to know the adhesion strength between layers to know roughly how strong the overall structure is. With enough sampling you could eventually have the info to do basic structural analysis, but I think initially it learning ideal layer adhesion control - how to consistently achieve ideal bonding. Once they have enough data, then they would be able to model something up and do analysis, and print full scale first time.
I'd be shocked to my core if all of that has already been accomplished and this print WAS printed full size first. Very surprised, though happily so. :)
@@Broadpaw_Fox Layer adhesion is a significant issue and a difficult one to overcome. You can see how it is addressed by Ingersoll at about 7:46 on the video. The Cincinnati "BAAM" uses a tamping device to get the layers to stick together. The Thermwood "LSAM" uses a compression wheel that follows the bead to provide adhesion. You can see the BAAM working in this video: th-cam.com/video/hct_k04VDhk/w-d-xo.html. You can see the LSAM here: th-cam.com/video/yUQ2-BZXvIQ/w-d-xo.html. Full disclosure: I sell Thermwood.
Obviously you could use independent secondary extruders for infill/bridging. These could provide just-in-time support for the main extruder, ideally so that its deposition rate is maintained within tolerances for whatever material is being used
wow its like you took two thing that i like and mix it together 3d printing and boats:)
Cool, I'd like to get one of those 3D printers but I don't think it would fit in my house...or my pocketbook! Thanks for the video, Paul!
I just got my 1st 3d printer and im slowly learner how to draw out stuff ... i love the tech behind this ... and the boat was a awesome idea ... any idea of what its goin to print next?
Have you tried a cooling bed with cold air rising with side walls adjustable Hights with air coming out if only aircon air or a dry ice holder or like a cooling system on a motor . older boat motors had a wraparound water cooling system but id say the closs up air wall with air con would be more viable and direct with flexible adjustments more practicable
Great interview! Very interesting.
That's a real big benchy lol that's very cool
Really wanted a benchy.
I’m a civil engineer with digital scanning experience. We can scan Constantine’s Arch in a single day. Do you think your printer could refine details down to a single mm? It could easily “print” the major faces to be glued together the construct a replica I believe just from what little I see now there would be very little bridging with the face being printed as a flat panel. I know I’m a dreamer!😵💫
Hi Paul, good day to you! Amazing! thanks for the sharing! what is your next program?
A possible use of a machine this large is printing recreations of lost historical items or statues
That's a very good idea.
Imagine being able to 3d print lava and make stone structures!
You do know sculptors are still a thing right? I know people use 3d printers to print statues but honestly, most people wouldn't appreciate it the way we do.
@Charles Stanford so long as there is a want for art, sculptors will remain. I find your lack of knowledge, disturbing...
This is amazing. Did you have to finish the boat to make it sea worthy? Do yall have video about the finishing?
9:00 you could solve this with having the nozzle diameter and feed rate reduce to get a larger bridge started, and then have the nozzle and feed rate return to normal and carry on. almost like a jet fighter exhaust
Awesome, Great video.
Fantastic American scientist! Congratulation.
I was expecting a huge benchy, cant say i was dissapointed. but i were a little sad not to see one
That same boat is available on Alibaba for $200, delivered.
thats the reason i think 3mm filament is a better choice than 1,75mm.
if you want you can use up to ~2,5mm nozzles xD
sometimes the small (0,4mm nozzle) benchy just doesnt cut it ;)
Great Job fellow Mainer!
I've been designing a EPC (Electric Pedal Car) and I'm looking into 3d printing the car body. Would you know a good place to get that done at? I don't mind the small pieces but I don't want them too small, that I don't know which piece goes where.
this need to print a 3dbenchy, and floatable benchy would be amazing
I’d love see more innovations
So that bridging issue, could you theoretically build a bridge for your bridge?
Like having different nozzles to print thin strands to allow larger beads above it to adhere without compromising the structure?
Yeah like a rotating nozzle assembly, with different materials for heat retention or dissipation depending on the need ie: Aerogel and copper nozzle for heat retention and copper with aluminum sheathing for heat dissipation. That would be awesome!
Have you attempted using supplemental prints to put in place when bridging is about to be necessary? May not be ideal but a viable stopgap until the limitations of bridging are solved.
Also, it's unclear to me why infill isn't possible (I believe that was said in the interview). Is that related to limitations to exceeding a 45° overhang?
I would put per heat roller ahead of nozzle to help adhesion, scene your nozzle turns it may work. Also i would try a universal joint to rotate nozzle 90 degrees for printing in the x and y axis's for overhangs and outer surface when it can be reached by the nozzle.
We have it but not workable on our 45 degree nozzle...and from testing, it has t worked ideally (yet)
I would love to 3d print the body for the batmobile to recreate it
Well Senator. It would be nice to be able to use additive to print spare parts except for a couple of small problems. Materials that may be hazardous, chambers that may require inert gasses, access to validated product data, trained and experienced users and others. Additive truly is a very cool and disruptive technology and there is no reason to oversell the technology. This overselling is the bane of those of use involved in the development and early adoption of advanced manufacturing technologies.
“My little friend” more like “my huge friend”
That's gotta take some time!
Thats one hell of a benchy boat.
I bet Cura could have sliced that boat.
beautifull !!!!
The first shipyard to realize that they can upscale this to fit a giant shipyard gantry crane (like the gantry on rails in this video but much much bigger, look up "Big Blue" at Newport News, or "Samson and Goliath" for an idea of the kind of thing I mean).... anyway, the first shipyard to modify their gantry crane with a giant version of this, designed to print in steel rather than plastic, is going to completely revolutionize the shipbuilding industry.
I need this printer to become viable for the small mom and pop shop now. I just need something about 8 foot long x 8 wide, and 4 feet tall. It could pay for itself quite quickly
Hey Paul. That’s pretty cool!
Question; how are they cooling the extruded filament; or is preheating the previous layer the issue here?
I like your style...
Hi! That’s a good question. Since we are printing so large usually we are trying to maintain temp between layers. But a great question for James to elaborate on
The Pentagon is showing an interest in this.They see great potential to 3D print the fast boats that the U.S. Navy SEALS uses on rivers.The U.S. coast guard is also showing interest in this type of technology.The next world record;building an exact replica,of the 205,000 ton;1,138 ft. long U.S.S. Gerald R. Ford aircraft carrier,entirely out of plastic filament.
The extruder doesn't have a cooling fan? I noticed you were printing in an open space, how does the moisture in the air affect prints or is that less of an issue jamming half inch beads out? Everything I've seen says printing carbon fiber needs a dry environment. It would be interesting to see a strength test with a heated chamber/dry filament for the entire print vs this.
The material is coming from our DryAir system and fed on demand. The material is dried for several hours before printing. No cooing fan on the print head currently.
Paul, OK... I'm impressed! I heard about 3D Printing only 4 months ago and I've been trying to learn as much about it as I can. Now I know how large an object you can print...a "BOAT"...WOW! But I still want to know how the process is started. I mean do you walk up to an object with a digi- cam, snap a pic of it then feed it into a computer... Then the computer asks you "How BIG do you want it"? That's the stuff I STILL want to know. After that... HOW MUCH ... $$$?? Time doesn't matter, but I live on the other side of the country from you. I'm thinking of something about the size of a typical kitchen "Refrigerator" (but it's NOT a refrigerator that I want duplicated). Just using it as a good size comparison. Jeff (out West).
Honestly if you use the contact info on the ASCC website, start there. If you have drawings and so on, that helps the large scale team. The machine is pretty booked for a lot of work. But you can always inquire!
How are the supports to remove?...…..Any sanding?.....Do you make your own filament?...….Great vid!

"My LITTLE friend, the world's LARGEST 3D printer"
Wait it looks like this printer requires no support! That’s awesome!
The man said it prints at “45 degree printing technique” if you watch the time lapse it looks like it’s sliced to print bottom top going “backwards” which is really cool.
Some close ups of the printer at work show small imperfections that shouldn't affect the final printed structure. Is this because of the large size axis precision or is it about the still uncalculated layer temp?
Dirceu Corsetti well i think it is allabout how fast they wanna go, go faster take less quallity i guess i am not sure.
Perhaps printing flat strips where one dimension is thin would help with the cooling issues.
Because of the cooling issue, sounds like 3-D printing on Mars outside in the low pressure will be extremely difficult simply because the material once heated up will probably take a very long time to cool down. Since the previous layer of material laid down must support the weight of the next layer of material, cooling between layers will be very important. And also very very slow.
They should have printed a 3Dbenchy :)
what about making car shells
Very cool 😎
Q: Could you explain the twisting? My "normal sized" hot end never twists, but I assume there's a really good reason why yours does.
My guess as to why the nozzle swivels is so it can make minor x-y movements without having to move the whole gantry and massive nozzle and heater.
@@pnwscitech1589 Plausible... but I'm fairly sure I see X and Y gantry movement and rotation about the Z axis simultaneously?
@@NoseyNick the bead is so thick that it won't change direction fast. Without the turning head it would just overspray an edge
Maybe focusing the cooling on the trailing edge of the print?
Could do bridging with a second head and dissolvable support material.
can we use this machine to print using ceramic powder?
I'm thinking 3d printed furniture. One of these in a town could supply custom sized and designed furniture, structures and obviously boats!
I'm going to 3d labprint a spitfire ,p47 and a Corsair lol lm going to need huge lipo batterys huge servos a gargantuan motor/esc and a really good radio control maybe a spectrum dx1,000,000 😂
That layer hight makes this whole thing look like it's printing ham. Can this print ham.
Sam I am! Sadly, I can’t print ham. Not even yams
Living in Maine I could see this up close but COVID…
I know other people have said this but please print a huge benchy that you could go inside of!
wow so damn coool guy!
How can i get time on this printer?
*ghosting appears*
Everybody: FFUUUUCCCKKKKKK
how much did the army box thing cost all in? where are you guys located?

I'd definitely see if Thomas Sanladerer and Stefan from CNC Kitchen would be interesting in doing some collaboration. They could provide some thoughts on some of the challenges that were mentioned.
We’d love to have them come over!
have you tested the boat,
A heat gun nozzle ahead of the extruder could warm up the previous layer(s) before deposition.
That’s why we have it 🙂
The boat you are showing may not be printed or may be significantly post-processed because the surface finish is very good which may not be possible using extrusion-based printing.
For real? View the time lapse
Liquid nitrogen would make for an great cooling method and would help your bridging distances.
How is the sea trials? Is it still available?
What are the benifits of 45° printing ? (Very strange method to print a cube when you are used with "standard" 3D printers).
I’ll add that to the list of things to ask
They can put a moving conveyor under the part they are printing and basically make something as long as they want without the need of larger print axis.
In a way they do explain that in the video, he says that bridging on that scale is out of question, because of the weight of the filament, so if they don't want to use support, and you want to create such a huge cube, with a 2-3m bridge, you slice it 45º, that way the previous slice is working as support of the new one. The question here is how we can accomplish this on our home printers, when there is going to be an slicer that allows for customize angled slice?
Look up NAK designs "White Knight" - infinite Z printer.
@@oscarvergara8770 Thanks ! Your answer and explainations is more clear and evident than in the video. You're rigth about your last question. A part of the answer is what will be the benifits to "loose" a lot of time in research in something that work fine for most of cases ...
Australia has a metal one that is expandable indefinitely so that is the biggest.
kindly provide me details of SLA 3D printer equal to FORMLABS FORM#L
How don't you have 1 million subs?
I have no idea. But thank you! Maybe someday?
@@WhereNerdyisCool fr, I have actually gotten interested into 3d printers quite recently, and thanks to you I'm even more excited to start 3d printing
Can you scan my advanced hull model and print a boat we can develop with the superior hull?
the should add a smaller printer head for bridging inside the structure and then continue with the bigger one to make the shell
Experimenting is key!
Is there a preset in Simplify3D? xD
Can the print parts for a larger printer 🤔
How much did that thing cost
You can basically build a house and a car
you need acoustic panels in your studio -
Well it’s the nerd cave but upgrades are always good ideas!
imagine a 3D printer printing a 3D printing thats printing a 3D printer...
how did they print the horizontal parts of the army shelter without support ????
Probably that 45 degree print method he was talking about.
If you look closely the nozzle is at a 45° angle. which means the layers sit on top of each other at an angle.
Is it possible to ask/know the printing speed, please?
If the math is right and I understood correctly the info, we have 2300kg circa as total mass printed in 72h.
2300kg/72h makes about 32kg/h.
If the layer height is 5mm and the bead is 12mm large, the area is 60mm2.
If the density of Carbon ABS is 1080kg/m3, 32kg/h/1080kg/m3 makes circa 0,029m3/h.
Dividing the mass flow for the bead area that is of 60mm2/1000000mm2/m2 makes 486m/h.
486m/h/3600s/h*1000mm/m makes 135mm/s.
If the boat was printed at 135mm/s seems incredibly fast, more than the average of small printers. It was this one the printing speed or do they used a different nozzle size for the boat?
Can we know what technics is it used for the adhesion and what are used for, the yellows pipes, please( Fume extractors)?
Good questions we can answer in an upcoming follow up video 🙂
@@WhereNerdyisCool Thanks, it will be really appreciate:) also because it seems not go fast as 130mm/s will be😅
is there any good source to learn about this technology and make a career/business in it'
3D Printing turned into my full time job 3 years ago. Check for places looking for people with 3D printing experience. I know some online places like Coursera and others offer Additive Manufacturing training
@@WhereNerdyisCool yeah I going for same course thanks for sharing good content !!
That 3d printer is really super slooooow. You can barely see it moving.
Get a nitrogen compressor from the oilfield to use for rapid cooling, it collects nitrogen straight from atmosphere and shoots the nitrogen down into gas and oil wells, so s line could be led straight from the compressor to the print head and the temperature could be controlled and adjusted by just simply useing atmospheric mixing into the nitrogen feed line running up to the print head , and if worried about nitrogens very low temperature, then perhaps they could use a CO2 collector just as easily. Problem solved, 😎
One of the features of this scale of printer is that very good interlayer adhesion can be achieved if the previous layer is still warm and so partially melts. This is why tweaking the layer times is so important.
I was really hoping for a 5M tall benchy
But the boat is awesome

Structural analysis?
What's the model of the 3D printer? Who and how muh did it took to engineer it?
