3D Printing General Discussion

[AKNick]

Thanks for that I am still in the sketching and figuring out mode on how to make the fan unit work and fit into a Delta type wing. But when I get so far I will ask for your help.
Where can I find the file for the IBec support.

You bet.
I haven't uploaded the file yet. Are you looking to get it printed or modified? Most of my files posted are not available to be modified at the moment (copyright stuff).

@AKNick just keep looking at your 3D printed stuff and just like what you can with it. If I draw up two air deflectors in AutoCAD-14 all three views and sections at 1 to 1 in mm would it possible for you to make it into a 3D printable file. I have no idea how difficult it will be. Thanks

Im not sure how the file would transfer to my program. My designs are basically top, bottom, and all sides on paper in 000.00mm. And determine the thickness of the material based on the application. 1.5mm-3.5mm. If you can draw up your sketched idea on paper so I can see what you are trying to accomplish, and where it’s application is that would give me an idea if I can do it. The trick with 3D printing is to keep your angles from the printing platform less than 55 degrees. Overhangs are tricky and I’m not that good with my settings.
Always happy to try and help!

Had a fan go out on my CR-10S PSU. It was vibrating bad, a little love tap and it would start working... so I took it apart and ordered another fan... in the meantime I also upgraded my Ender 3 with a MicroSwiss Direct Drive All Metal Hot End. Fun to put together... about a days worth of figuring out my slicer settings and it’s up and running. Still more tweaks to go.

now that’s it’s printing. I ordered some HTPLA to try out with the printer. I’ll have to anneal the part to heat treat it to become molecularly bonded and more resilient to higher temps so it won’t deform as easy. Stay Tuned!


HTPLA is from Proto-Pasta here in the USA.

micro Swiss is also made here in the USA

Hmmm annealing thin plastic in an oven... what could go wrong? Lol
It warped at 230F at 9min. Supposedly I can go as low as 210 at 6min. May need to make some practice pieces.

this is my wing pylon/bomb drop for my jerry bates bearcat. It wil have a micro servo attached to the top to fuction the unit. Its spring loaded for easy attachment of the bomb. I've also designed one for the top flite p-47. Wonking on cockpit stuff too

good work!! That looks great!

3DPrinted Airplane Tires!!

I’ve been wanting to try this for a VERY long time. Used some old 95A TPU I had purchased years ago for testing.

My plan was to use the tire on my 4” SpotOn rim, but after seeing 14 hours per tire on the printer I decided to reduce the scale and make a test tire which took 3.2hours. Being my first ever 3D Print with TPU I’m pretty impressed. TPU generally likes direct drive extenders, slower prints, and a hotter extruder based on my research. So with my Ender 3, KCamel Green TPU, 45mms, 225C, 60C, and a microSwiss I printed my test piece beautifully.

I’ve been following Airless/Non-Pneumatic Tires since they were under development. The major car tire companies have their own designs patented but not on the market with the exception of the heavy equipment (skid/steer) and ATVs.
Polaris has a hexagon style
Hankook has an hourglass style
Michelin has a S style and X style
Goodyear has a crisscross x pattern

I’ve developed my own and dubbing it the jelly bean pattern…. I think
I cannot unsee that this pattern looks like a bunch of alien faces that morph when squished. If I only knew how to patent a design…

overall I believe the pattern works, but is heavy. So refinement is next.
