Mine works great, no broken parts or DOA electronics, and a good strong support community if you have issues / questions.

I got a reprap Wilson II. buy here, about $500:

And read most if not all of this:
http://community.reprapwilson3d.com

I'm using Simplify3d right now with great results so far. Not free (about $150) Very happy with the purchase. The slicing software has as much or more to do with good print quality as the machine does.


Can't believe how cheap it is for how nice the parts are so far of you're not afraid of building your own machine, I'd recommend it. AND you can save at least $500 by building it yourself, and as much as $2000 if you build it. I was gonna buy a $2500 machine, but they were out of stock. So I saved $$$$, had fun building it, and it works.

Here's some pics of some test parts I'm working on tweaking the settings on

Lil bit of progress


Got some work done!

Life has been crazy but i got some time this weekend to work on this thing.

The outboard wing sections are cut without any features... i think ill start simple with them and just build them out with kevlar hinges for the ailerons and slats.

Cut the wheels too but not really happy with them... might have to rework those...

Not really visible in these pics but i also got a lot of the flat parts cut like the vertical and horizontal stab spars and the flap stuff and the nacelle/motor mount stuff

Cut the cargo and nosegear doors out too. Then bonded the fuselage halves together.

Progress little by little. Looks cool all taped together

Beautiful plane... I am completely clueless with 3D printing technology, is it possible to make foam parts? Thought it was only heavier plastic.

Technically yea they can print foam parts - but those machines are big and expensive

The machine I'm using for printing this stuff is best for just regular basic PLA. It can print ABS but it's tricky. Recently started messing with carbon filled PLA - results are promising so far. Helps the stiffness and helps raise the service temperature slightly. In some cases enough to get over the threshold of melting in my car... Or not melting in my car lol

Also, thinking about trying this out, mocked it up out of cardboard...

A spludder?
Spludders?

Would act as an airbrake, I think... Would probably cause a pitch up effect when deployed... But it's too easy to execute and try...

Look like decent machines. We are using the crap out of mine... We may need a replacement/upgrade soon. Thanks

Motors and props bolted together. They look like props bolted to motors... Awesome

Got the spackle applied last night sanded down for the most part. Pretty much ready to glass the exterior surfaces

Why 3-blade and not more efficient 2-blade props David? Ground clearance? Sound?

Prettig weekend Ron
