DeHavilland Swallow PSS?

[Doc J]

kinda off-topic, but it's badass...

Surprisingly quiet.

What a beautiful streamline. I can imagine the isobar lines flowing over that fuselage...DeHavilland aircraft were always so good looking - I know, I used to work for them!

Its going to be a 60" PSS winner.

Looks awesome!

Better look out Jure, I might send more work your way!

 

[jure]

current status, some progress made !

Love it,

Do you have enough wall thickness to give James something to work against? Might want to dial in the print settings to get a smoother finish too.

 

[jure]

walls are 1.2mm , very solid.
these are most of the relevant Cura Slicer Settings:
suggestions for change ?

Filling and glassing the outside of the printed structure is already in the plan Wayne - but thanks for the heads up.

The flexibility of the final plug has been a point of some discussion between Jure and I - especially from me who has no real experience of 3-D other than some really dodgy servo trays Frank had made, that turned into a handful of plastic gravel as sooon as they were flexed.

I can see places already that will need to be faired in with a nice fillet, but thats something I prefer to do later anyway, as then I can make sure the glass in the eventual moulds will "listen to what we say', lay down nicely, and not do its own thing causing bubbles in the final parts.

This could be one of the advantages of printing I guess, as the external features and surfaces are far easier to control and to alter than CNC machined version. Who wants to take a sheet of 100 grit abrasive paper to a CNC-machined Michelangelo?

Its going to be - already is a fun project, and quite different from my usual methods of producing a model. Jure and I are enjoying it a lot especially the email "tennis" we are playing to get the thing further along. Kind of a double-take OJT exercise

Another thing is that its always very inspiring to work on something unusual, but something that you can easily work out on paper will actually perform very well. Gives that extra impetus.

Thanks again for the input, and please all - do help us by asking questions and making suggestions! More brains = more horsepower.

Cheers,

Doc.

Rafael says it looks like your filament has way too much moisture. So first thing first get a dryer.

If you still have similar results with the dryer (let your filament dry for 24 hours minimum) then try reducing your print heat some.

Wow...good advice from the Maestros!

Thanks Wayne - I'm sure Jure is tweaking the settings. Dry filament? wow thats getting into it.

one more piece ...
the span is : 390 mm = 15.35"

Woo...printer porn...

Are you not entertained? Wow!

Luvvit!

brand new Comgrow PLA filament just off the package , and lower hot-end temperature have improved things.
Thanks Wayne and Rafael !

there is still some very fine 'angel hair' stringing , 'emanating' from the post with hole for the part alignment pins , which may be seen at the center.

Looking real nice Jure. Enjoying the progress.

 

[Doc J]

So far...Note: Jure changed to a new type of black filament - he's going for that "Cubist look...

Its coming....
Cheers, Doc
