Printing Saturn V (one more)

[Chriske]

Neil,

I do not use a downloaded file to print SaturnV.
I only downloaded a model and printed it 45 cm high. That little rocket is my 'lead'. I do all external measurements on it and draw only a shell. So it's in fact own design.
Infill 0% and what's more most of that shell is even printed as SpiralVase. This complete construction is superlight. All parts will be bolted together with threaded rods.
Although it is printed with a 1.5mm nozzle the outer perimeter looks very good. Inside it looks a bit 'stringy' but I don't care about that.

These models look awesome... I'm itching to get my self a 3D printer and join in the fun...

Just do it...!

As for the USA-text and black parts I'm planning to draw and 2D-print all black and red on self adesive plastic.
I only need to know what typeset is used for the text.  Seems to me that it 'USA' text is written in 'Arial'.

So many ideas and project to be had and done.... so little time.

Part 8 (for part 7 I need a bigger printer)

I'm now at about 84cm

[Gina]

Bigger printer - more height or more width?

Width
My biggest one is 200x300mm.
Ring nr 7 is a 'small' one just 30-mm high  199mm diameter

This was a difficult one to draw in Inventor.

This is the most upper section of second stage and start of the third stage.
After I finished this part I'll change nozzle, think I'm going to use 0.7 instead of 1.5mm
Third stage is only 131mm diameter.

I've thought about a hangprinter but haven't got an empty room.  Maybe one day.  Mind you, I promised myself I'd never build a "pink string and sealing wax" printer again!  I can't see a hangprinter being very accurate using umpteen metres of "pink string" braided fishing line cord even if it is "minimum stretch".

I'd use archery bowstring. Now that is minimum stretch. And I have a load of it.

Finished printing part 9

[Chriske]

Part 7 was to big for my bed so I cut that small ring in half and will bolt the parts together. Printing them now.
All parts except for the main thrusters are done. Busy drawing these thrusters now.

[Chriske]

All parts almost done now, busy drawing the main thrusters.
Can't post a picture because I don't dare to stack'em all on top of each other without these threaded rods through them.

[Chriske]

Escape tower is almost done, still that first part of the primary thrusters to draw/print.
All parts in the picture : printing time 18h 3minutes
Hight will be 1m93cm. Going to add a launch platform and flame deflector.(Not printed)

[Gina]

Coming on well

[Chriske]

Thanks

Done drawing, starting printing the thruster-units now.

[Chriske]

[Chriske]

Still a few very small items to draw, but for these I need a 0.2mm nozzle.
These very small thruster are hardly visible on that small rocket I have. Hardly measurable, but I think they're about  18mm wide for my own model. Ridiculously small.

[Gina]

Good luck printing those tiny parts, Chris.

[Chriske]

Only 11 minutes to print that TINY thruster.
Printed with a .4mm  nozzle, just to see if it works.
Layer 0.9mm.

Result :

This the ugliest thing I ever printed, during these past 6 years.... yuck..!!
This little thing definitely needs a 0.2mm nozzle.

[Gina]

Are you sure you mean 0.9mm layer height?  Yes, agreed - that is amazingly bad for you! 😄

[Chriske]

Good point Gina, silly me..! What was I thinking..🙄
Not 0.9mm but 0.09mm layer-height of course...

[Chriske]

Almost done printing. Still a few flame deflectors, ailerons and thrusters to do.
I have a few orders for this rocket already.
Meanwhile just started assembling my first SaturnV.

 

The cross shaped part is there to guide the most upper part with a threaded rod.

[Gina]

Looking good

[Chriske]

A few hours later ....

I'm at 1.7 meter now
Still busy printing thrusters @0.4mm nozzle. Takes a long time.
I wanted these thruster high quality, that's why 0.4

And yes, still struggling with these tiny upper thrusters...😡
