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.
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
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?
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
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.
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
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
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!😵💫
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?
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!
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!
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.
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
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.
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.
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.
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.
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.
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.

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 ;)
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?
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.
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?
@@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 ...
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.
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.
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.
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)?
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?
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 😂
But one thing that could be done is using compressed air to massively cool down the "beads" once layed down! With such a big abd heavy Machine comes the opportunity to use way bigger and more sophisticated cooling then possible on any hobby machine! I bet there would be solutions with enough airflow and a huge high pressure nozzle directed towards the lower part of the orifice to make the extruded filament cool down almost as fast as on smaller scale machines. Would love to see some expermentation being done and you filming it!
The problem would still be the thermal capacity of the hot plastic. As the plastic is extruded, it comes out in a flattened sausage shape which has a small surface area to volume ratio. You could blow all the cold air you want at it, but you'll only end up cooling the outside of the bead and create a solid shell, the heat will still be present at the core of the bead. This solid shell may negatively affect co-layer adhesion, as the newly extruded plastic needs the old layer to still be warm in order to weld effectively. High pressure air is also a force to be reckoned with. Increasing the pressure wont make cooling more effective, it may end up just blowing a hole through the molten plastic. So the other option? Use colder air? No, this will lead to a shell like before and risk the shell then cracking as the heat at the beads core spreads back out. You see this happen when you put an ice cube in luke warm water, it cracks. The only real solution that I can see is to engineer a new plastic with better thermal characteristics for the application.
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
I am under the impression that SpaceX has been doing large scale 3D printing for sometime now. Also I heard that the largest printer is in China. Just wondering what differs from your printer technology and that mentioned above?
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
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?

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!

Hi Paul, good day to you! Amazing! thanks for the sharing! what is your next program?
Liquid nitrogen would make for an great cooling method and would help your bridging distances.
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?

The problem would still be the thermal capacity of the hot plastic. As the plastic is extruded, it comes out in a flattened sausage shape which has a small surface area to volume ratio.
You could blow all the cold air you want at it, but you'll only end up cooling the outside of the bead and create a solid shell, the heat will still be present at the core of the bead.
This solid shell may negatively affect co-layer adhesion, as the newly extruded plastic needs the old layer to still be warm in order to weld effectively.
High pressure air is also a force to be reckoned with. Increasing the pressure wont make cooling more effective, it may end up just blowing a hole through the molten plastic.
So the other option? Use colder air? No, this will lead to a shell like before and risk the shell then cracking as the heat at the beads core spreads back out.
You see this happen when you put an ice cube in luke warm water, it cracks.
The only real solution that I can see is to engineer a new plastic with better thermal characteristics for the application.
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.
Australia has a metal one that is expandable indefinitely so that is the biggest.
size of fillamnet?
Pellets !!
How can i get time on this printer?
This is some daily dose of internet shit
imagine a 3D printer printing a 3D printing thats printing a 3D printer...
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 !!
kindly provide me details of SLA 3D printer equal to FORMLABS FORM#L
All good, but where is the 3D printing video of boat ? Which is the headline 😀
In the video...if you actually watch the video 🙂
Is there a preset in Simplify3D? xD
Nice video, please balance volume levels of video (inside your shop is very loud, interview was quiet)
I’m sorry. I assumed most users knew how to adjust their own volume 🙂🤓
@@WhereNerdyisCool Ok
Seriously... always trying to improve! Amateur video editor 🤓

Thank you! Hope you enjoy the content!
Could do bridging with a second head and dissolvable support material.
I am under the impression that SpaceX has been doing large scale 3D printing for sometime now. Also I heard that the largest printer is in China. Just wondering what differs from your printer technology and that mentioned above?
Ours is the largest polymer. The others I’ve heard about are metal printing or concrete 🙂
Beed adhesion!
Gravity! 🙂
You can basically build a house and a car
What is price for this 3D printer?
Millions 🙂
What's the model of the 3D printer? Who and how muh did it took to engineer it?
Ingersoll Masterprint
Largest POLYMER EXTRUSION printer.
Let's be specific when we make BOLD claims. Eh?
Can you scan my advanced hull model and print a boat we can develop with the superior hull?
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
Very cool 😎
That 3d printer is really super slooooow. You can barely see it moving.
I was really hoping for a 5M tall benchy
But the boat is awesome
Maybe we should connect to the laptop
