LSAM 3D Printed Marine Boat Hull Pattern

[@mgrantom]

Wow. I grew up building fiberglass sailboats the old fashioned way. Made wooden plugs, hand sanded to use for making the mold. This method is quite an unbelievable time saver. Of course I am sure the cost is pretty incredible too.

[@donziperk]

Mark Grantom I did the same as you. For 10 years I worked for a company that built moulds for various boat and bath tub builders. It was an art building them from a pile of lumber and fibreglass. I don’t think many people understand the hours of shaping, sanding and polishing that went into the plug. Biggest I worked on was a 97’ pilothouse motor sailer.

[@테스트유튜브배우-x5c]

그런데, 3d프린터를 만들어줬는데, 5년이 지나도 사람들이 안써. 도대체 왜 그럴까?

[@craigrmeyer]

I'm impressed that you somehow managed to have zero porosity in that outer layer, after the machining step. I'd never have guessed that was possible, and surely took some effort to make work in real life.

[@christianfilloux]

They dont need zero porosity. They seal the surface and then polish it with wax as a mold release so they can use it as a plug to create a mold. The red part is the mold that the production boats are made from. The black plug (3d printed part) is just used to make the mold.

[@rogermccaslin5963]

The machined pattern is sprayed with a polyester based coating and then sanded and polished before applying release agents. There was also very likely a high build primer coat before the finish coat. This video shows Thermwood's machine capabilities but barely touches on the entire process.

[@lucianosantucci108]

I wonder if traditional machining of foam and then finishing is a faster method.

[@micro963]

Thanks to 3d printing there is going to be an easier way to create models analyzed them and test them before going into production, that will minimized a lot of room for error, labor, material and time consumed. The 3d printers are getting cheaper and cheaper every day and there are a lot of different options out there might not be as the one showing in the video, but you can get a small one and start practicing creating small boat models, I love it, thank you for the video.

[@ThermwoodCorporation]

Thanks. Just an FYI, the 3D printed boat hull in the video was used for the production of the Tahoe T16 boat. press.basspro.com/tahoe-boats-introduces-new-boat-model--designed-to-get-more-families-boating-/

Can you go bigger like a 35-70 ft sail boat?

[@ms_vibe9918]

Why did you mill again (using the 5axis cnc) after 3D printing the plug???

[@stateservant]

When smoothening the surface of a printed object with CNC, should we use roughing or finishing on the CNC toolpath?

[@ThermwoodCorporation]

Hi @statesservant. Typically a finishing toolpath. But there are times when an extra roughing operation may be needed. Totally depends on the build of the print.

[@stateservant]

@@ThermwoodCorporation Ah thanks a lot. I would, from my intuition, also use directly a finishing toolpath, just without any stockmodel. I think the question is, how accurate should our printer be.

[@slevinshafel9395]

why dont use High density foam if you have CNC to make the temporary model?

[@ThermwoodCorporation]

Hi Slevin, We can and have used foam to make models, however high density foam is expensive in both labor and material and you end up machining most of it away. This boat hull plug took about 10 days from start to finish by printing it in 6 pieces (3 days). With VLP, that 3 days is reduced. The below is from a tool that we printed vs a traditional tool made from high density foam: blog.thermwood.com/polysulfone-offers-promise-for-3d-printed-composite-tooling-blog-0 Comparison vs Traditional Methods A mold for the same part was built by ACE using traditional methods and the cost and build time was compared to making the same tool using additive manufacturing. The results were stunning. The Results Additive manufacturing material cost was 34% less and it required 69% fewer labor hours. Build time for the additive tool was 3 days versus 8 days for the conventional tool. If the part was larger, a support structure would be needed for the conventional tool which would add two days and more labor hours to the conventional process. A larger additive tool would not require a support structure.

[@rogermccaslin5963]

@@ThermwoodCorporation Coming from a boat building background, I started out building plugs the old fashioned way - wood, fillers, sanding, sanding, and sanding. Then I graduated to 3d modeling and cutting plugs with a 5 axis router using high density foam. I could never go back to stick building plugs. I'm curious about the numbers. How did you come up with the labor savings? Gluing up blocks of foam can't be more labor intensive than gluing up the printed parts. I would think machine time should be fairly even. Likewise, the finish work on the machined surfaces should be pretty close to equal. Where does the labor savings come in?

[@ThermwoodCorporation]

Hi Roger, If you are talking about the previous answer, those savings came from an aerospace tool that traditionally is very labor intensive. With our VLP (Vertical Layer Print) option, we can now 3D print that same boat plug in 1 piece. Also, instead of 3D printing the plug, we would go straight to the mold eliminating the plug process. The video of the 3D printed boat hull took a total of 10 days to complete. Machine time is the biggest factor. thanks,

[@spanishjo4282]

World best technology! My son is a 3D expert too.

[@powdemonic7121]

Will this reduce the cost of building a boat or will it just make it so the molds can be reused more often? Or is there some other advantage to this as i am unsure.

[@ThermwoodCorporation]

The boat mfg didn't give us their exact costs and time for their traditional methods. This particular boat mold had about $15,000 in material costs and from start to finish took 10 days to complete. That's printing, assembling and machining. Another example: We 3D printed an aerospace tool for a customer and the customer compared using his traditional method. Additive mfg. material costs were 34% less and required 69% fewer labor hours vs traditional methods. Build time for additive mfg tool was 3 days vs 8 days for conventional method. I believe the same would go for additive mfg of master plugs for boat hulls. Yes, according to our understanding, this method will greatly extend the life of the mold. Thanks!

[@blakanal7222]

Is it cheaper than the usual way of machining an XPS Core, put paste on it and machine it again?

[@djmjr77]

Freaking awesome!!!! Im trying to do this on the R/C scale and its pretty difficult ...

[@BoozyWoozy]

BFP - Big Fucking Printer. How cool it is, just as expensive. And after molding, do you use gelcoat spraying to make boats?

[@ThermwoodCorporation]

Hi, We just 3D printed the plug. They will be pulling the mold from that plug to make the fiberglass hull from. I believe White River Marine Group used a gelcoat

[@3dprintwiz378]

Biggest question is does the 3d printed one float? And where you the same company that made that 3d printed car, and if not, why not make one?

[@ThermwoodCorporation]

Hi, we didn't print the final boat hull. We 3D Printed the plug that will be used to create the final product. We did not print the 3D car (Strati). That was before we created the LSAM. Local Motors used a different printer to 3D print the car. Then our 5 Axis CNC Router was used to machine the outside of the car body and other components. At this time it is not feasible to 3D print a car. There is a faster way to do this. Plus there are a lot of details that have to do with safety that has not been addressed. The LSAM can 3D print tools and molds used for vehicle components. Local Motors new project is the Olie (Autonomous Bus) which our LSAM is printing the chassis as well as other components. The Olie can be used at College campuses and theme parks as well as other places.

How much does it cost to print the boat? What kind of 3D printer is used?

[@ThermwoodCorporation]

Hi Quinton, This particular boat mold had about $15,000 in material costs and from start to finish took 10 days to complete. Thats printing, assembling and machining. The printer used was our Thermwood LSAM (Large Scale Additive Manufacturing) system

[@QWTrucker]

Thermwood Corporation that’s awesome you guys are awesome I would love to come work with you and learn from you

[@djsbuds123]

Does this make for a cheaper boat to buy?

[@titter3648]

how can you print a part that big with no heated bed out of ABS and have no warping?

[@ThermwoodCorporation]

Hi, With no heated bed or environment, we control the cooling for each bead using our patented layer time control. Also because we use a large bead, we print near-net shape so if there is some warping, we still have some extra material to machine.

[@davidantill6949]

How fantastic...someone can have a library of bespoke hull designs which can swiftly be made into molds. The process of iteration will accelerate exponentially. Wright's law will also lead to costs plummeting exponentially too.

[@Peter-jl4ki]

Swift is a relative term. The entire process from start of print to finished mold probably took a week. The main selling points are that duration and cost are more predictable, and it saves on manual labor.

[@slevinshafel9395]

Economicaly what is better? make all this step in this video wit 3D print or just make CNC on highdensity poliuretan and after that make the mold?

[@ThermwoodCorporation]

Hi Slevin, I can give you a couple of examples. We 3D printed and machined a mold for an oil drip pan cover that goes on a helicopter. A composites company near us created that same mold using their traditional methods. The following were the results: Additive manufacturing material cost was 34% less and it required 69% fewer labor hours. Build time for the additive tool was 3 days versus 8 days for the conventional tool. If the part was larger, a support structure would be needed for the conventional tool which would add two days and more labor hours to the conventional process. A larger additive tool would not require a support structure. Another example is the boat hull. We 3D printed the tool for the boat hull in 3 days. It took a total of 10 days from start to finish. Normally it would take weeks or months to produce the same tool. Another example is we 3D printed a mold for a helicopter blade. Additive Mfg. took 3 hours to print. Machine time took about a week. Normally it takes months to get the same tool.

[@M33TFP]

And cost?

[@Jeremy-fy1sz]

Well, tooling typically costs a shitload, my guess is its a fraction of other methods, and really accurate.

[@brobrah4595]

Cost will NEVER be revealed. Its either so cheap that its kept secret to stifle competition or so expensive that its off putting to customers. Its a game companies play that any human that consumes should already be aware of...

[@wordreet]

I can't find anything about their pricing, but from looking at their website and seeing the scale of the machines, not forgetting that this included a milling machine, my guess is around 5 to 10 million bucks.

[@ThermwoodCorporation]

Hi Terry, are you curious about the cost of the LSAM or the cost of 3D printing the hull?

[@ThermwoodCorporation]

Hi, please email [e-mail] for more information and pricing. Thanks,

[@fooman2108]

Print something 10mils bigger than the finished part, CNC trim it the final 10mm, and imagine the time (and cleanup/wasted material) you will need! Drop the mold, print another. Change and intake (different propulsion), print a new mold. Structural reinforcement in an area (lights, weapon mounts, ski ropes), print another one. A truly practical idea for 3-d printing. Want to make a bet that the newest design for the C-9 won't come from something like this?

[@ThermwoodCorporation]

Hi, Sorry for the late response. Having to glue up a blank using wood or foam and then machining most of that material away is the traditional method. We printed the boat hull and end up taking off about .25" (6mm) of material. The print consisted of the shape of the hull and not a big rectangle with much more material that needs to be removed. The material being used for this is ABS with 20% carbon fiber mix so very tough material vs wood or foam.

[@starhopper457]

That was cool to watch, but I hope that boat has a strong transom with additional supports!

[@ThermwoodCorporation]

Hi David, We are not 3D printing the final hull in this video. This is the boat plug for this project. White River Marine Group wanted a 3D printed plug to then create the mold from, which then created the final hull.

[@ExploreComposites]

That's amazing! Is the bed heated or just using the glued pellet method? Those big piece look like they could really warp, but it seems like they don't.

[@ThermwoodCorporation]

Hi, The bed is not heated. We use our patented bead board which is pellets glued to a plywood board that is secured to the table. It doesn't warp much due to the carbon fiber fill in the plastic pellets.

[@RFi731]

How did you print ABS that huge without a noticable shrinkage?

[@ThermwoodCorporation]

Hi, All of the plastic materials that we use including ABS all have a certain percentage of carbon fiber. This helps with shrinkage and strength. Plus we also control the cooling per layer instead of heating the entire envelope.

[@RFi731]

@@ThermwoodCorporation sounds like a great method! How did you control the cooling?

[@ThermwoodCorporation]

We developed "Layer Time Control" which is a feature on our QCore Control. This feature will automatically control the speed at which a layer in printed to achieve a set time per polymer. Each polymer has a defined set of characteristics. The printed layer must cool to a specific temperature range before the next layer can be printed.

[@richardsurey6167]

Wouldn't it be quicker to print one piece a a time because of the transition between pieces for each layer?

[@ThermwoodCorporation]

Hi Richard, Because the LSAM's bead is very large, we print in a room temperature environment. With this process, print speed is essentially controlled by the cooling rate of the polymer being printed, rather than by the output of the print head. The printed bead must cool enough to support the next layer, but must still be warm enough to fuse completely with it. This means that there is a specific temperature range, which is different for each polymer, where this approach to printing works. Each polymer requires a certain amount of time to cool to within that temperature range. That amount of time is the fastest that a layer can be printed, regardless of its size. All of this is automatic in our control. In a nutshell, we need sufficient time between layers to cool. If it takes 2 minutes to print a layer and 2 minutes before we can print again, you can either print a bead on another part or move the machine into a "Hot Hold" area and wait 2 minutes. In that video we are printing 2 pieces in the same time that we would print 1 piece. Sorry for the long response.

[@richardsurey6167]

@@ThermwoodCorporation great answer, I wasn't thinking about how much heat is held in a bead of material from a larger nozzle like that. I wonder if you could speed things up with multiple smaller nozzles laying alternatively, get some of the initial heat out

[@ThermwoodCorporation]

Hi Richard, Smaller beads would help with temperature and speed but would require more passes. We tried to use fans to help cool but that was very inconsistent. As far as speed, we printed a helicopter blade tool that was 18 ft long x 3' x 3' and it only took 3 hours to print which is quick - kzbin.info/www/bejne/farFl61ui52bfq8. The multiple nozzles idea is interesting and would need to think how that would work with our patented compression wheel that is used to compress the current layer to the layer below pressing out any air pockets/voids which also makes for a nice bond.

I did not understand anything. CNC could cut the same shape from high-density foam. Why did you need to print the workpiece? Аre уou not interested with savings in cost and time?

[@ThermwoodCorporation]

Typically these master plugs are created using wood (possibly foam) but someone still needs to make a blank by gluing foam blocks together. This takes time. It typically takes weeks if not months to create the same Master Plug for a boat hull that we 3D printed and machined in 10 days. The material that we used for this will also hold up longer than foam. Just like I mentioned in the above replies, we did 3D print an aerospace tool for a customer and the customer compared using his traditional method. Additive mfg. material costs were 34% less and required 69% fewer labor hours vs traditional methods. Build time for additive mfg tool was 3 days vs 8 days for conventional method.

[@chriscook1468]

Serhiy Lonko: Great comment. I would think a CNC cut of heavy foam, (5 to 10 lb), would accomplish the same thing for a lot less money. Maybe the longevity is an issue. For limited production, the foam idea is great. These guys make the cnc machines that do that. Very interesting stuff.

[@Fryhs]

How many times can you use that mold ? Can you reuse them

[@ThermwoodCorporation]

Hi Mr. Y. Some of this will depend on material and application. If using a high temp material used in Autoclaves, we are unsure about how many cylces a 3D printed mold can endure. A customer of ours is testing this now. For low temp materials used in the Marine industry as well as others, the mold could be used multiple times. For example, we 3D printed a mold for the cast concrete industry. They have been able to pull hundreds of concrete parts from the mold and still no degradation. If the mold was made of wood, the amount of pulls would be a lot less. 3D printed molds can be ground up and turned back into pellets. Because plastics lose some properties when heated and cooled, generally you will use a small percentage of regrind material with virgin material.

We shipped the boat hull a few thousand miles on the metal skid (shown in video) and didn't have an issue with the seams.

Hi, Sorry for the late response. This was a new design that the boat mfg gave us to print. The LSAM's main target is not to produce the final product but to print tooling, molds, masters, plugs and fixtures for a variety of industries such as aerospace, automotive, marine, foundry and thermoforming. Companies are looking for a cheaper method to produce these tools than traditional methods and additive manufacturing gives them this. An example of savings is we 3D printed an aerospace tool for a customer and the customer compared using his traditional method.

Hi Eric, the boat mfg didn't give us costs and time for their traditional methods. We did 3D print an aerospace tool for a customer and the customer compared using his traditional method. Additive mfg. material costs were 34% less and required 69% fewer labor hours vs traditional methods. Build time for additive mfg tool was 3 days vs 8 days for conventional method. I believe the same would go for additive mfg of master plugs for boat hulls.

Those joints makes me wonder if they’re strong enough. I had poor results with some joints.

[@ThermwoodCorporation]

Hi, The epoxy that we used has been very successful in this process. We have transported this boat hull over 1000 miles and used fork trucks for picking up and placing the hull numerous times with no issue. We are working on our VLP (Vertical Layer Print) option that would allows us to 3D print this boat hull in one piece.

[@lucaribeiro6123]

@@ThermwoodCorporation that would be amazing! I was very curious about the nozzle diameter but I guess that is sensible information? Keep up the amazing work!

[@ThermwoodCorporation]

Hi Luca, the nozzle diameter is .5" (12.7mm)

[@77gravity]

Wow. no real sense of scale until the assembly phase, and then Wow that's a big print.

[@AtlantisRouTou]

Yeah, I also thought it 1m x 1m or so )

[@ThermwoodCorporation]

The build envelope of the LSAM in the video is 3m (10ft) x 6m (20ft) x 1.5m (5ft) Z

[@Hellsong89]

*sees the video* Ou cool! I wonder what scale that is and what kind of propulsion this will have *parts on the shop floor* ...Ou that was not a RC boat XD *Plug goes to 5 axis cnc router* even more amazing! Any chance of getting 3D model files to make scale RC boat?

[@ThermwoodCorporation]

The boat plug that was printed is at full scale. They will be pulling the mold from that plug to make the fiberglass hull from.

[@Orc-icide]

So this isn't a print in place boat

[@mkivy]

And where are the weakest parts of this build? The seams ? The Glue? Logistics in H2O for lone periods. The effects of salt water on hull? We shall see…

[@SuperYellowsubmarin]

Please give us a rough estimate of the cost !

[@ThermwoodCorporation]

Hi SuperYellowsubmarin, please email [e-mail] for more information and pricing on the LSAM. Thanks!

Why the loud music? Its very annoying

[@ThermwoodCorporation]

Hi, We 3D printed the tool that was used to create the mold which is then used to create the final hull.

[@Юрийббб-ж8ъ]

@@ThermwoodCorporation understandably , why don’t they print boats and small vessels, for example, from polyvinyl chloride? after all, you can also print large parts of the suln and then weld them in the type of passopirone plastic pipes.

[@ThermwoodCorporation]

Hi, We could very well print the boat hull and it would float, but there are numerous questions about integrity, speed, price and more. White River Marine Group wanted us to 3D print the tool. The link shows that WRMG made the final boat hull from the 3D printed tool. press.basspro.com/tahoe-boats-introduces-new-boat-model--designed-to-get-more-families-boating-/

[@Юрийббб-ж8ъ]

@@ThermwoodCorporation that's all i understood so de understood that there was a question about loads and wear resistance, but did not understand why the case was not strung out of plastic as a half-worn final lethal. For example, I thought about searching for panels with enclosed air cells and the innovative system of fusion testing at the construction site - assembly.

[@schlaznger8049]

Why not just 3d print the hull in one piece instead? No seams to leak.

[@ThermwoodCorporation]

Hi, We are not printing the actual boat. We are printing the master plug. The boat mfg. uses fiberglass to create the mold and then the actual boat is created from that. We had to print this hull in multiple pieces because of the size. We are limited to 5 ft tall. We are working on our VLP (Vertical Layer Print) option that would allows us to 3D print this boat hull in one piece.

[@schlaznger8049]

Oh ok, that makes more sense. I was not trying to be smart as I did not know. Thank's for answering.

[@Dude-yo5ec]

Ok it was awesome... The first. 3D printed an actual useful object :)

[@mindpuzzle81]

Actually most companies are using 3d printing in mould injection processes and have been doing so for quite a while.

[@michaelespiritu2908]

Awesome

[@arielerosa3204]

I'll be naming mine the Prin-Tanic once i get one and sinks.

[@mysticalsoulqc]

hi, I conceptualize some innovation with 3d printing and oxides...etc... but haven't hade the chance to be supported in my builds. I actually put in place these types of devices, for now, robotic arms... for the people by the people so we can all participate in what you are doing would you like to make a video, I have so many questions and we could share your success story with the world on both are channels more for you, and me to show people my vision can be realized. much appreciation for your share, graphene boat would be cool? you can contact me here or on Facebook and if I can ask how much did it cost you to build that you went all out on this one. you have the state of the art devices that thing is like 250 000 setup right? not counting the warehouse?

[@flypic1098]

Very impressive.

[@bmpowellicio]

Well, yes, but you'd think that the design would be a little bit more 21st century after all that effort. Whats more, I don't think the 3D printing stage adds much. Why not simply 5D cut the hull from a solid block of material? That would be far cheaper, too. Go see what the Indians are doing with high-tech boat production, they have a few years more experience with complex layups of resin-insused forms. Playing catch-up is never easy.

[@ThermwoodCorporation]

Hi Michael, Just like making a tool for about anything, if you start off with a big block of material, you end of machining most of it away. We offer CNC machining centers that do just that. 3D printing allows us to print an object that is slightly bigger than final size so this requires very little material to be taken off. 3D printing is also quicker than machining. Generally what we have found is that machining takes about 3 times longer than the print cycle depending on geometery and finish. Currently we are looking to 3D print the hull and deck in 1 piece as we work with boat mfg.'s. I will check out the high-tech boat production. Thanks

[@haworthluke]

Layer height 8cm

[@ThermwoodCorporation]

Hi Luke, the thickness for each layer is .51 cm (.2 inches) and width is 2 cm (.83 inches)

[@haworthluke]

@@ThermwoodCorporation lol i thought it looked thick compared to what I am used to (0.6mm). Amazing result though I love to see people pushing new technologies to their limits. are you a boat company or a machine company? I will have a closer look at your channel soon

[@ThermwoodCorporation]

Hi Luke, Thanks. We manufacture the machine. We 3D printed the tool for the boat hull in conjunction with White River Marine Group. The bead is pretty big. The nozzle diameter is .5" (12mm)

Sooooooooooo this is not a 3D printed boat. THIS JUST A MOLD NOT A PRINTED BOARD

[@--dh--]

How were the pieces secured together?

[@ThermwoodCorporation]

Hi, We used Lord epoxy to bond the sections together and used machined pins for location purposes. We also used zip bolts but probably didn't need to.

[@jappecoco]

Cool, thx for sharing
