Using 3D printers in my work!
 

Hi Guys,

I want to share with you some proyects that I did at work for several events. As some of you know I work for a software company and "part" of my research is on a 3D printing area... we decided to push the limits to see what can be done with these machines at a larger scale for the "physical prototyping" before it goes to final production. All designs where made using our software that we produce, Autodesk Inventor. We are using for these specific designs 3D Printers from Stratasys. All prototypes are scale 1:1. Every single part or hose is ABS plastic that came from a 3D print. The turboprop simulates rotation via the electric starter in combination with the planetary gears.

And yes.... I get to make a few parts using these machines for my turbines helos or my Jet planes too!!!

Have fun with the pictures,

Gonzalo

And here is another project that I did last year:

Holy S&$T!!!!That is awesome!!!!

Any reason why you chose FDM as against SLS ?

For us who do not have these fun toys to work with I found an article that explains the differences between FDM and SLS

Hey where did the awesome photos go?

RE: Using 3D printers in my work!
 

There is no doubt that what has been done is brilliant a great achievement.
I ask the question purely out of interest, FDM has its uses, i use it, but i am not sure I agree with Materialise on all points.

FDM has strength issues in the layer plane and is not ‘solid’ due to its nature of construction.

SLS offers a range of very good materials including carbon fibre, steels, nylons (with and without glass) when built this way parts are fully functional, I know, I use them and also supply Formula one teams, military, automotive, medical and aerospace.

Nice job Gonzalo[sm=thumbs_up.gif]

Would you have any intrest in doing mechanics for a quarter scale helicopter?

RE: Using 3D printers in my work!
 

How big is your printer? I know it is bigger than 12"x12". Butch

RE: Using 3D printers in my work!
 

Wow, Gonzalo! I remember you saying you did things like this! So it seems, theoritically, parts can be designed and then machined out? Or cast? Wow!

Wow, when you described what you were doing, I would have never guessed it was even close to this... amazing.

Now I know where I'm going to build my L39... haha

RE: Using 3D printers in my work!
 

Not machined or cast, they are 'built'

FDM
Fused Deposition Modelling
A fine (hot) filament of plastic is extruded under the control of an XYZ table to ‘create’ the part in layers, each layer fusing to the one below.
SLA
Stereo Lithographic Apparatus.
Uses a laser to selectively change the state of a resin from fluid to solid.
Again, this uses the layer principle.
SLS
Selective Laser Sintering.
This uses a bed of fine powdered material and selectively melts the material on each layer to the next layer (etc). Depending on the material selected this can produce a working finished part with good characteristics (including steel)

The beauty of each of the above systems is that parts can be made direct from CAD 3D data.
No 2D drawings required.

Other systems are available.
JSD
LOM
SLM
3D printing (many types).

Gonzalo, no wonder why your helis are such a work of art....... all you have to do is to push "Print" ....... LOL.

Congratulations. That is impressive leading edge technology.

Thank you so much for the nice comments!

Here is a quick video!

Are you going to be at Westec in March?

RE: Using 3D printers in my work!
 

That is wicked...pure magic :)


Just put it to good use, and make some super scale jet plugs for the jet manufactures to produce.

RE: Using 3D printers in my work!
 

I think the Stratasys folks will be at Westec in March not me.

Love this 1/4 scale!!!! for electric or turbine? I wish i can help you with the mechanics but I have "0" time. Talk to Darrel S. you can contact him at [email protected]
He just did all the mechanics for his 1/4 scale Jet Ranger electric.
