    I'm very keen to go have a look
    Abs would be an amazing plastic and you could do an acetone brush on the interior skin of the hull to weld it up but it's such a pig to use without getting warping.

    One of the reasons my build of Claudio's Narrow has ground to a halt was the purchase of a Prusa type acrylic printer. I used it to create the mould for my bulb and got that extremely close to the desired weight.
    I also just printed my first test mould to create a rudder. The test finish was excellent at a print height of 0.1mm with a 0.4mm nozzle.

    And this is the test layup.

    So for myself, I'm sitting somewhere between yourself and Claudio. I'm using the printer to create moulds that I can use more traditional methods on. This gives me better resolution than my handcrafting skills allow but I can reference proven cloth weights etc. Having said that, one of my main reasons for not attempting a completed hull is my printer is not up to the task imho. I'm having z-axis issues at larger heights so hopefully I can give it a bash down the line.

    Nice work, Naptalene.

    A good printer is a significant investment, but the good news is that a professional printer is not required for good results. Of course, the best that can be afforded is the way to go, then time spent testing and working to eliminate things like reduced accuracy at the upper limits of a build. Printing is Selwyn's domain, not mine, but I can say that a printer like the Wombot Exilis can do the job. Perhaps with some more refinement to your setup, your printer can do hulls, too.

    Because of the printer cost, Selwyn and I have always shared a vision of the printer being a club resource. Most clubs probably have a couple of geeks like Selwyn and I...one who likes to design and one who likes to engineer. Maybe that's the same person, or maybe the designer is someone whose files are published like Claudio or myself. If everyone in the club chips in to fund the printer, it suddenly becomes much more affordable. All club members can then benefit by having hulls and parts printed at very low cost.

    Selwyn and I have had some chuckles during our project, because we are, in fact, prototyping our own vision. The club in our case is a small group that has collaborated, each contributing a particular expertise. And we've even demonstrated that the "club" doesn't have to be local...ours literally spans the globe, and the only frustrating part of that is having to wait a week or more for printings to ship from Australia to the USA!

    Have you seen the resin printers .... OMG I need one lol.

    Are you guys available anywhere in particular to answer some questions? I'd love to know things like wat brand of filament, material, height resolutions etc. have been chosen for different reasons.
    And silly things like how you choose where to cut the hull, what kind of joints are you using, which glues etc.
    Are the files of hulls available blah blah blah lol. I'd love to be able to try print out an existng design where the stl's have been made so I can have a benchmark of things.

    Cheers
    Andrew

    Andrew, Selwyn has offered to answer questions here https://3dprintedradioyachts.com/que...ontact-selwyn/

    I suggest you read all of the site material, then be as specific as possible.

    I went there last night

    I was worried that I would be bugging him in his personal capacity as opposed to on a forum

    I'll get my questions coherent and then send him a mail, thanks.
