I 3D Printed a Life-Size Boat (The PRINTcess)

[@NefariousElasticity]

Now you and Emily need to collab for a race to see who's Benchy is truly superior

[@real_e]

I think Emily's is better in terms of being an actual benchy, not a different model. But in terms of being a boat, this guys is better. EDIT: not taking sides, they each have their strong points

[@Bawed]

@@real_e fr

[@DragnEYE]

@@real_e Emily just sized up a model... She put effort into assembly, but this guy actually made a functional boat, and I think most people would associate this boat with a benchy. Don't get me wrong I don't dislike Emily's video but this is way cooler and much more functional.

[@forivall]

Oh, I think Emily would fully accept that this boat is functionally much better; as, she's all about the janky, she's the queen of the bodge, the matriarch of the kludge

[@gatling216]

Emily's Benchy is a semifunctional shitpost, and that's amazing in its own right. But as a boat? Ehhhhh, not so much.

[@c1ph3rpunk]

“As a good engineer, I decided to do the math AFTER my design didn’t work”. Holy crap, soooo relate. You’d think we’d learn. “No more boats!” (she didn’t say airplane)

[@tinkerduck1373]

I remember when I assembled my XXL DIY 3D printer. I had missed something. The 3D drawing was ok but I completely ignored how I actually would assemble it and that there needed to be space left at least for a tool or better for a hand... 🤦‍♂️🪛

[@barrymayson2492]

Yep been there always seems that the idea is its driving force until physics gets a foot in the project.

[@Un1234l]

That's naught a boat. Now THAT'S a boat.

[@commander-tomalak]

Hi! Small correction at the 27:02 mark: the foam inside the hull does not alter the displacement of the hull and, therefore, does not provide any surplus buoyancy compared to an empty hull shell. On the contrary, it adds weight and pulls the boat a bit lower into the water. It only provides any surplus buoyancy in the case when the hull is breached, since it won't allow any water ingress into the cavity inside the hull shell. As long as the shell itself is intact, the foam literally only adds weight to the hull and does not improve buoyancy one bit ;)

[@dmdeemer]

You are technically correct: the best kind of correct.

It lowers the center of gravity, so in theory, it improves the stability. But I don't know if it has a big impact.

Thanks again for making a long format video rather than the 16 part series on how to “tap a nail”, even with forced sponsor ads it doesn’t detract from the entertainment. Thank you for staying original throughout, it really is appreciated

[@Nifty-Stuff]

This is the pinnacle of 3D printing and youtube content!!! Brilliant work!!!! You make such incredible content. Keep it up!

[@hollt693]

I feel I owe you an apology for my doubt/impatience. This was truly an impressive build that had far more complexities and challenges than I could have ever imagined. Well done! In the medium size range, you could print a benchy large enough to wear as a hat... but then it'd be capsized.

[@PatrickKQ4HBD]

Take my upvote and get out of here! 😂

[@RyanMercer]

Curious to see how different it'll be from when Emily the Engineer did it.

I honestly thought you would never do it the last time you mentioned it. BUT YOU DID!!! Absolute star, top job Prof. I'm so impressed.

[@ChampionXperienceOfficial]

We like people who design, modify and produce instead of producing ready-made designs. This was a really impressive project and I watched it breathlessly.

[@broyout3586]

This is so cool! I tried to float a freshly printed benchy, but I couldn't get it to stay upright, it capsized immediately. I concluded that a benchy doesn't really work well as a boat 🙂 Color my surprise you are sailing around in one! Mega kudos!

[@pianokid4520]

Hey, I love this project. Can’t believe your printer made it look soo flawless! :) good job. And I wanted to say you should try to make a speed boat next.

[@ShopHumor]

My dude, this is freaking incredible. Well done.

[@Luke42652]

Not only the largest Benchy, but the most functional. The last one made required ballasts to keep afloat, and that took away from the original design. You added a keel, but they are low profile and you can't see it in the water, so that's a big win!

[@kgomotsomosimanyane9569]

Dr. D-Flo you are the Master. I am learning a lot from you.

[@hermanzaum]

Thanks!

[@DrDFlo]

I really appreciate it! Thank you for the support

[@SpencerPaire]

Great project and great video! Im so glad someone finally made a REAL Benchy! But one criticism I have; really, displacement is the *only* way to float. It might be useful to think of the density explination in some cases, but it ignores the fact that the mechanics at play are exactly the same. It's just that density directly correlates mass-displacement to volume, without any geometry tricks. Also, floatation is independent of surface area; there is no correlation between depth of float/displacement and surface area. I imagine you ment cross sectional area?

[@DrDFlo]

You are right! Sorry, the reason I brought flotation vs displacement up is that if a boat is constructed from a material denser than water, then it will sink to the bottom of a waterway if it capsizes. I had an irrational fear that my boat would sink due to gaps in the layers or some other miscalculation and I wouldn’t be able to get it out. I appreciate you taking the time to leave this comment!

[@PMcDFPV]

....Im not missing that video right now! Great job man!

[@DrDoohickie]

Incredible! Great application for your printer! I’m surprised you didn’t make a sieve machine (siever?) to automate separating the pellets.

[@DrDFlo]

Ah we should have - great idea! I kept underestimating how long it would take to sort the ~800lbs

[@KnightsWithoutATable]

@@DrDFlo Yes, it will take you forever to hand sort even 100 pounds. Also, I would put a metal detector in thee auto sorter just in case there fine metal shavings the sifters in it don't catch so that you can stop it since apparently anything can fall into the plastic production line.

[@andrewlhoover]

I met you all at the TN Maker Fest back at the end of September. I shared your video link with my robotics group who are always very interested in all things maker.

[@buildtestbuild]

Awesome project! In my opinion it's the benchmark for a life sized benchy. Very smart to add the foam into the hull, doesn't add much weight but prevents the hull from ever taking on water!

[@drstefankrank]

This won't win any speed benchy contest. Still top notch. It is very clear, that just a sized up original model won't do it and it has to meet certain features to be registered. Has some Steamboat Willy vibes.

[@XenonG]

He technically is in 1st place for this size category.

[@DragnEYE]

I think that is way faster than like 99.99% of benchys actually. 3 MPH isn't much, but most benchys don't have motors.

[@HybridRobotix]

This is TOO COOL for KZbin!

[@ChristianBehnke]

That's amazing - well done! 😎

[@jupiter2142]

What was the thought process for picking the Archimedes chord infill pattern for the hull? Wouldn't grid be better since it would provide more area to support the front section?

[@DrDFlo]

So any infill that overlaps in the same layer is difficult for my extruder to push through due to the larger extrusion widths and is more likely to cause the part to come unadhered. The reason I selected Archimedes is because it is the longest most continuous infill, which minimizes non-printing moves. Pellet extruders exhibit more extrusion artifacts when starting and stopping.

[@jupiter2142]

@@DrDFlo I see, thank you!

[@AntCooke]

I love this. it turned out really well. I also enjoyed the quirk of his accent that made him pronounce hull as hole. Lots of tittering when he talked about flat bottom holes etc.

[@jamespray]

Thanks so much for sharing all the ups and downs of this project. I have a suggestion for a follow-up project: do another boat, but do it in vase mode with the least possible material, and then skin the shell in resin + glass or CF, and compare the material and time investment against this one, alongside the usability of the final product. I think it'd be educational and revealing about how to efficiently apply a machine like yours in light of the scaling challenges of the materials and processes we're using at a desktop scale in the FDM world.

[@zog6940]

Very happy to see that you sealed the entire exposed side of the hull with resin. On your reddit post a few days ago, you said that "it's printed water tight" but that you had gone over seams with resin. And I got torn apart in the comments for daring to mention that no FDM print (or pellet fed) is fully water tight, due to microscopic voids between layers. So I'm super happy to see the full layer of resin to seal it all!

[@alexhill2852]

Well, he did say in the video that the outer epoxy is for making it easier to clean/scrub and he mentioned specifically it was not for water tightness, so not sure what you are aiming at. That said, I would have also expected such a step to be neccessary for making it water tight ao I was surprised myself. And after all, he also does show one leaks later in the video at 28:12.

[@zog6940]

@alexhill2852 it shows him covering the entire hull with resin. He said on reddit that resin was only applied to the seams. I'm just glad he coated it in resin. Because, again, NO FDM prints are ever going to be perfectly water tight. I don't care if the guy in the video says it was printed water tight. It's not. Leaks are inevitable. Resin helps with that immensely. Thank you for coming to my TED talk

[@chrisdriver8453]

[@daoudkamal7768]

what you couldve done in the boat design is including a keel/center board inorder to make it easier to navigate against current and wind, but also lower the center of mass.

[@skeeo7393]

Longships actually had rocks at the bottom of the hull to lower their center of gravity since they were made to be able to navigate shallow bodies of water and the north sea. It could be something to think about if you ever do another boat.

[@airgunningyup]

painting the whole boat with laquer might have been easier for waterproofing, but not foolproof either. Incredible job!

[@robbie1606]

Awesome boat. I like that you printed it from 3D printer. You guys should try a sit on kayak too. Make it in two or three pieces easy to assemble and screw together to make a bit easy to manage.

[@katelights]

if you do decide to do a version 2, I think it should be 2 segments wide and 4 long. and design it so you can fill the bottom of each segment with cement.
