The Eric Mc honorary thread on 3D printed model thingumies.
Discussion
So, Mr Eric Mc has kicked us of his thread for talking too much b
ks about 3D printed Corsairs (see here) so here's a thread all about 3D printed models - let us know what you're up to!
I am currently printing a monster (1.7m) Spifire MkIX which I plan to turn into a MkVIII and paint it up like A58-303 because it's aloooominum and super cool.
I have a fully printed but half-finished P38 that needs some work and re-work.
I'll post some pics when I find some place to host them.
In the meantime I want to hear about dr_gn's 3D printing exploits and other interesting stories. Fire away!

Fantastic.
The topic deserves an obvious thread of its own.
I don't think I'll be acquiring any 3D printed model technology any time soon but it's a really interesting area and I expect many of the after-market accessory operations are already looking at how they can harness this technology.
I'm not sure what your design is supposed to be but has an aeronautical feel to it.

The technology scares me, because I don't understand the mathematics and am not clever enough to master the computer science part of it because - old
BUT isnt it a fabulous time to be living when we are seeing this beginning to make massive inroads in even our hobbies as well as 'real life'
I love the 'look' of your printed aerial being is it a bird?
Is it a plane?
Whatever it is a marvel

I designed a drone that doesn’t look like a traditional drone with 4 or 6 helices but rather like a plane designed to both fly very fast and silent and to have outstanding hoovering capability.
It comes very close to AER’s design. I haven’t detail-modelled the aircraft yet but we are working on it.

It's not so much the stability as the resolution. You need ultra fine nozzles and layer height which leads to a really slow print time.
There are ways of finishing them afterwards to smooth them out too.
But once made, will the components last, or fall to bits at first sign of rain/sunshine/cycles thereof?There are ways of finishing them afterwards to smooth them out too.
PLA isn't supposed to be great, it absorbs moisture which can really affect its structural property, eventually causing it to break down (it is biodegradable). At a guess I'd suggest after a year or two outside it wouldn't be faring well. If using it for trim in a car you'd have to be mindful of general temperature, the temperature cars can get inside could easily start to see PLA deflecting and going soft.
ABS is the other main material used but I don't really have experience with it.

I think ABS is commonly used for injection moulded parts throughout vehicles these days anyway so it's pretty robust. Not too sure how UV-stable it is though.
As far as printing with it, most of the cheaper printers (Prusa-style etc) will struggle to print it. Ideally it needs an enclosed and heated print bed and a printer head that can maintain a 260°C+ extruder temperature. Even then, controlling thermal distortion during print can be challenging
The flying wing I posted above is printed in ABS. I've had to compensate in some areas for warped part ends to make it work by printing extra length and trimming/filing/sanding. This is usually not necessary with the 3Dlabprint-style aircraft printed in PLA.
ABS can be acetone smoothed and glued with acetone-dissolved ABS parent material whereas PLA generally cannot and is glued with CA adhesive.

At last a model topic on 3d printers. Hurray.
Got me a cheap Prusa i3 and does more than I want it to I'm using mine to make small parts for RC drift cars and about to start on a scale garage project over winter that i will use it to make benches and tools etc.
They really are fantastic bits of kit. But so frustrating, took me three months to get mine working right but now it works great.
I'll get some pics up of stuff I've made at some point.
I'm thinking of making an RC boat with mine as like the idea of making it and then floating round the local pond.
