The USS At Louis at 80cm would take an age to print. I assume that something that size is printed in sections?Comment

This is a 1/56 model from Thingiverse by user 'W_Rec', blown up to 1/35
This shows a problem with upscaling.... what is OK in 1/56 isn't really detailed enough in 1/35 the underside is devoid of any detail. Printed in 12 parts ( 6 of them wheels ), with supports that came away easily - I think I'm getting the hang of supports finally

I was right-LOTS of post processing, but it looks bloody good!
I love the guy's accent too!
Very inspiring, and proves what I have been saying all along-this is the next stage in our hobby.
How much is the file to buy? I bet it's a lot cheaper than a kit and theres' nothing to stop you printing it at 1-72 scale if you have the patience!Comment

just checked it out- it's FREE to download!Comment

Yes,
I've done that - my computer really struggled to open the hull files in PrusaSlicer - and even longer to slice! At 0.15 mm layers it would take nearly 2 days to print. I did use Bambu to slice the same part at 0.2 mm layers & slightly less fill, and it would still take nearly 10 hours to print. With 5 sections, that's a long time & that's just the beginning. The instruction manual has 20 odd pages.
This would be more in the line of a group project, or one person with multiple printers!
One of the Ultra-Fast Delta Printers may improve on this. The hull itself is too large for consumer SLA printers, but the small parts would be ideal - just pack as many as you can on the build plate.
It's certainly an impressive model, but probably in the future! I did look at doing a 1/350 waterline version ( there's a full hull .stl file provided ), but even that would take about 12 hours to print, and there are so many small parts that you could probably treble that!

The Matilda has turned out to be a non-starter - the hull was impossible to clean up, and the tracks, road wheels & suspension, being all in one piece are only suitable for a resin printer. My computer struggled opening the track files, so at least I've learned what can't be done!
As a consolation, I looked at the 1/150 scale USS St Louis again. I decided that 1/150 was too big, so I have scaled it down to 1/250.
The hull is in 5 sections, joined by rectangular connectors. The first part I printed was the bow section ( left ), this took about ten hours - I realised after it had finished that the % infill was too high, the thing weighs a lot!
The second section, I reduced the infill from 25% to 18%, it took 11 hours 12 minutes! The next section is the largest, and the software is predicting 13 hours. I'll have to change my filament spool, as I want to be sure there's enough filament - I don't want to run out of filament after 12 hours!!!!!!!

You really are having fun with this aren’t you Dave

fun and exasperation! Bizarrely, the thing I thought I would have no trouble with is the CAD side of things - I'd been so used to using one particular system that changing to another is proving difficult - maybe the old grey cells are digging in their feet and refusing to learn yet another programme! Luckiily I've found loads of things from the 'net that I can print!
