Good progress made today on printing the underwater hull. One of the biggest problems is that the Azipods are so small - but managed to get them to work - prints a little bit stringy - but I think I can clean them up.   1:1000 version (which is 1/4 of the size of the big ship in this thread) now more or less complete - just need to do a final reporting tomorrow with the bow thruster props and stabilisers too.

 

Thanks Javelin for the info  - have updated the bow thrusters to add in motors that are on opposite side of propellors that turn in the same direction.
Will add some grills too at some point

I had a further look at the ship and think I know where you got that. The three markings on the hull, where you located those thrusters are actually signs to show tugs where they can push. They're not thruster marks like on the bow. 

 

She doesn't have stern thrusters neither, since the azipods can be used sideways aft. 

Thanks for the feedback - have corrected the underside of the ship to a) Remove 3 thrusters, b) Swap the direction of some of the propellors, c) Aim the stabilisers slightly down.

Have also included some Fusion 360 renders too

Great thanks for the feedback and you are correct I thought those signs on the side mean't there were thrusters there, so will remove them.
 

Plus will also angle the fins down a bit.

Also I think I need to change the direction of the propellors too on one of the azipods and two of the remaining thrusters.

Finally got round to modelling the underwater parts of Arvia - presented in this pictures underneath Iona - as I assume the two sisters are probably identical under the water.   Not sure if I have got the proportions correct, shapes quite right, or whether I have missed any bits.

Will probably just apply these additions to my 1:1000 versions initially.

Got the shapes from various photos on Cruise Critic and YouTube.

May contact yard as suggested a few months ago - with this pictures to see if they are willing to help with better pictures or plans.

Now installed in upgraded cabinet with rest of fleet.

Finished. Might just add a few flags. Biggest problem now is finding somewhere suitable in the house to display it.

Quite pleased at how the high ropes etc. print came out - had to resort to thread to rescue a couple of failed sections - but maybe I should use it a little more for some other ropes.

Closer to realistic high ropes now modelled, plus some corrections to deck 18 - not sure how well it is going to print though.

Bit of yellow staining on some white parts - so should have increased flushing volumes, but will do for now.  So that's all of deck 18 now complete.   Might reprint though with a more sandy yellow colour filament if I can find a suitable one.

Just deck 19 and funnel to go now.

Finer details of onboard crazy golf coming along - quite please with roofs of little shacks - did it with a loft, which is shelled, then on one surface put some random sketch lines, then did pipes along each line.  Then did a circular pattern to replicate the lines over each face.

Now complete up to Deck17 - most of deck18 ready to go - just the high ropes and golf course to add detail to.

Biggest issue is fixing Deck17 down - had hoped to do this deck with magnets - however proving difficult to get them to fit on the underside.

Quite pleased how the Sun Beds came out.

Just discovered this fantastic thread on Cruise Community. Arvia Construction  wish I'd found it earlier - but will be very useful for later below waterline additions.  Plus I think I will also try and break the 1:1000 version into real sections as they were delivered - might try making a video that intersperses the parts being delivered and then being built up one by one.

Deck build up continuing to progress nicely - also interesting to see the difference in scale between this 1:250 model and the 1:1000 P&O Cruises Ventura model that I am also working on.  Its a slightly smaller ship - but looks tiny compared to Ariva 250.

Next stage is to Model more detail into Deck16 before I can print it- particularly the swim up bar at the back.

Ship really starting to take shape.

Hi Dave,

no, still the same

Sorry about that - mine didn't seem to appear at first, but it is now coming up in the 'Overview section' - just beneath 'content view behavour'

 Hoping too see the Arvia's 1:250 model soon on Printables!

Haha - Given the lack of interest in the 1:500 models I published - probably won't bother releasing 1:250 models any time soon.  Plus this will probably be the only one I do myself as printing it is taking weeks to print the 100+ plates, plus I don't have the space for too many.

I am however going to opposite direction - currently prototyping a 1:1000 version of Ventura that you can print on a single plate.  About 6 hrs printing time single colour and about 20hrs multi colour. 

Now up to deck 11, with deck 12-15 ready to print (Luckily the middle 4 sections of deck 10-15 are all identical).

Had some challenges with Fusion 360 - particularly relating to changing my deck section joining method over from 'tight dovetails' to mostly 'springy T slot' (other than the centre joint with is a 'loose dovetail' to allow for dissassembly. 

Quite pleased with furniture demo on Promenade deck, and example person in controversial  'Balcony Mini Suite'.

Will likely also create a 1:1250 version of Arvia model too - as _CNPICs on printables has printed my Iona 1:500 model single colour in one go at 1:1250 and it came out surprisingly well.    Iona 1:1250 print.  

From a distance and with my eye sight deck8 stern print looking pretty good.  

Could perhaps refine the tiny models a little bit or maybe use a different filament for the arms - its PLA Metal.

Still quite pleased with the results.  Back section took about 8 hrs to print.

Back section of deck 8 printed on 0.4mm nozzle, rest of ship so far all printed on 0.6mm Nozzle.

Quite a few changes to design required to incorporate wiring for LED lighting.

Lessons learned.

1. Don't leave floors too thin when adding in cable runs - otherwise reprints will be required

2. Making the internals of the ship more hollow would make it much easier to add things like lighting for other future models.

3. Doing cable runs below decks is easier to manage than above - as wires can be taped in place before decks are bolted down

4. Allow inter deck holes to be big enough to accommodate shrink wrapped extensions to smaller wires

5. Make designs for LED holders more generic - to allow for changes to lights - and add ons such as individually addressable LEDs.

6. Consider having the collection point for the wiring at the bottom rather than near the top - so it is easier to handle wiring without having to worry about hiding it.

7. Check that cable routes are efficient and won't result in the need for extensions.

7. Consider adding wireless inter deck wiring interconnects like these in future designs - to make putting the model together, taking it apart and maintenance.   

Changes made to design to incorporate wiring + LED holders

Deck7.  - New channels and LED Holder

Deck8 - new channels

Deck16 - with space to wiring hub

Deck17 - LED holder

Deck18

Deck19

Funnel

I would enjoy seeing something relatively simple like a Longboat.

 

The steps learned could be easily applied to a more elaborate design.

Funnily enough i have been considering modelling some of these rowing boats in Fusion360 as i think they will make quite attractive 3d prints in different colours- Could also make an interesting video.
 

i guess it would be best do do the overall hull shape first, then work out how to create the separate wood slats that wrap around it.

Will see if i can work out a good way to model one then try doing an instructional video.

Dave, great model and I’m jealous that you have a Bambu for printing. Speaking for myself, 99% of the learning curve in f360 is around specific methods and when it gets to hulls, the more complex end of f360. For instance, how do you use splines, how do you project lines into thin air, that sort of thing. This is where Kevin Kennedy and Lars are usually so good. I think a voiceover is essential. Back when I was mostly learning, I watched a lot of vids and kept coming back, mostly to the former, because he explains topics very well.
 

Somewhere on YouTube there’s a very long, detailed screencast video of a chap modelling a hull in F360, but no voiceover and it’s almost impossible to understand what he is trying to show sometimes. That’s a great shame because there is definitely a gap for a tutorial around hull creation, when to loft, when to sweep and especially how to fair the basic shape. You’d be doing a great service to humanity - well, a small slice of it if we’re honest - by taking on that task!

Kevin

Kevin. I think you are right about the voiceover. Plus I have improved my methods a fair bit since doing this video - so should really create another version.
 

My Iona/Arvia design for example ended up using a form/tspline for the fairly complex stern, but still lofts for the bow and main hull.  Also the main difference in modelling approach was to only model one half of the ship.  With mirroring of bodies done fairly near the end of the timeline to create the other half.

Backloaded build log.

17/7/23

P&O Cruises Arvia progressing well - fairly easy as it's pretty similar to Iona.   Fusion 360 model is actually now of both ships - with some components and bodies needing to be switched off and on to switch between the two ships.

Printed up to Deck 15 in Bambu Lab Sponsored Filament - and design changes for Deck16-19 now made - and ready to start making printable and printing over the next few days.

Most complicated part was high ropes and crazy golf etc.

9 colours

19/7/23

First completed print - Arvia is the right hand ship

Some Fusion 360 Renders

Also did a fair bit of work on Fusion 360 export macros - rather than exporting 100s of Bodies that need to be coloured in Bambu Studio, new version of macro only outputs one body per colour per section of the ship (by going through the fairly slow process of hiding / showing / exporting the separate groups of bodies).  Will publish new macro on Github at some point.

25/7/23 =- Yellow decks reprinted - plus High ropes improved 

27/7/23 Design changed to include some lighting - render of expected look

31/7/23 - Lighting being added

1/8/23 - First lit version - with 9 LEDs from old BrixMax Lego lighting kit

It will likely take a bit of research but I would start with Meyer Werft.  I have been given drawings by shipyards in the past when I told them I was interested in building a model.  These were pleasure craft, but it might work for your project as well. 

Allan

My main area of gap is in the underwater profiles.   So far I have only modelled above the waterline - but would like to try adding below waterline parts too - partly for display and partly for possilbe RC conversion and floating - so will give the shipyards a try first.

Update - I now seem to have a signature option when I access Ship Models for a desktop Mac on Safari - other attempts were from a laptop and iPad

Hi Dave,

These are absolutely fascinating.  Did you get the plans through Peninsular & Oriental, Carnival, Meyer Werft or elsewhere?

Thanks for starting this log.

Allan 

Allan - I just used the deck plans that people use to choose their cabins which are not exactly to scale, then used photos and videos. Would be good though if i coupd find a way of getting access to the proper plans for these sort of ships.  Dave
