Summary

Not just another Brio Railtrack!
This Flextrack can be bend sideways, upways or downways to build curves, bridges and to overcome obstakles!
check out this short clip: http://youtu.be/rw0LYmu16r8

It's designed to be printed in single-line-style!
with superfast printing (300mm/sec @0.24mm) it takes 12min with regular printing (60mm/sec @0.2mm) it takes 35min

features:

  • rail track can make 90 degree turns
  • the running surface has extra ziczac's for smooth running
  • the male and female connector do flex-press-fit
  • it's lightweight and quite rigid!

this thing was made in tinkerCAD, go remix it! http://goo.gl/yPv6ve

UPDATE:
I made an extralong version! 195mm! Should still fit into most 3D Printers...

Instructions

for printing, i used the spiralize-option in cura, but you also can also just print without infill and a single-wall setup (optimized for 0.4mm nozzle)
i also used 20% more flow as the standard setting.

you can print this thing very fast, there is no part where it needs to be super precise...

At first I thought this was a train laying it's own track.

Wow, very clever!

Hello,

I have try to print this cool design on my prusa i3. I have this issue :
I can't go farther than th 1st layer. It start printing properly but durring the layer print, the head mouvement (no printing) cross the already printed lines and screw them all. This mess up my print.
Does some one has this issue and how I can deal with it ?
Thanks for your answer,

Marcox

what slicer did you try? with cura and the "spiralize" option checked, there should be no jumping across at all.

Nice model. I think lots more folks would print it if they didn't have to turn the floor/roof settings off. What was it modeled in?

hi! i made a remix from this http://www.thingiverse.com/thing:22244 in tinkercad - i simply placed a lot of cuts:) here's the link again: http://goo.gl/yPv6ve

the thing with single wall prints: it's the most efficient way to print (super fast and nice surfaces) - but probably not the easiest:) especially to come up with a true single-wall design can get quite complicated! here is a tricky one: http://www.thingiverse.com/thing:35770

so if you wanna print a lot of rails, it's quite cool if you only need a fraction of the time:) and floors/roofs take most of the printing time...

even more powerful single-line prints get when you can make the printhead move in a spiral accent... cura and sli3er have this "spiral-vase" option...

Oh, don't get me wrong... I do agree with you regarding printing with a single wall. When I printed it I did "2 shells" for better strength but without a top/bottom... but not everyone knows how to do that.

In our lab we have a Ultimaker 2, a couple of Makerbots Replicators (dual and 2x), and a Form1+ resin printer. The issue isn't with the idea of printing with a single wall, it is that the MakerBot software doesn't give you an easy check box to turn that or the continuous vase option on and off. The FormLabs printer is almost worse because everything it prints is completely solid, there is no "fill" option.

There are tricks to printing without a top/bottom (roof/floor) but in the makerbot world it scares people off and I know that those users tend to steer clear of models that require those printing settings.

I think your model is great, I was just saying (maybe I shouldn't have) that more folks would print it if there were another thin walled version. That isn't the easiest thing to do in tinkercad.

Thanks again for posting it, it works great!

and of course you're right! it would make things easier for everyone! but making a thin wall object that works properly with standard settings... is indeed not an easy task:)

i have several ultimaker's and form 1+'s in my lab... with the form1's... i often use the "hollow" and "make pattern" options in meshmixer to save a lot of resin... (but no nerves... because it's crashing all the time:)

Funny... I imported your track in to meshmixer to see if I could do a quick hollow fix... but it wasn't so easy. I know I could do it in other tools but instead just wrote the blog post about "printing topless" with the MakerBot software. (path of least resistance - just trying to help others).

Your lab sounds pretty cool. I can't say I'm a big fan of our Form1+ but I am making an effort to make some things with it that just show off it's strengths. The form 1 doesn't seem to like tight tolerance gaps, like that heart keychain I made, so it is taking some getting used to...

EDIT: Scratch that- I should have waited longer to post here- it's hollow completely (0% infill)- but the bottom/top is shell... is there a 0 shell option? That seems strange to me... I still have a ton to learn!! Thanks for this model! It's brilliant! I'll let you know how my son likes it! [Of course I think it solves a problem we all have- everything on the track looks great, but we're missing that one shorter or longer piece with a weird bend in it. Thanks for a solution!!]

I'm having an issue with makerbot software on this one for the replicator 2x... seems to infill the empty spaces in your springs above. [See the other make picture posted by another maker.] Not sure how to turn this off! I used the settings and suggestions you gave, but it appears to be doing a complete infill? I can see through your prints, but mine is printing semi-solid (except for the spring outer surfaces).

hi there! hmm. i googled quickly and came up with this: https://groups.google.com/forum/#!topic/makerbot/bAETzUIXor8

there is no button in makerware to simply go into "single line mode"...but with editing a profile... it should be quite simple as well.
there is many awsome singleline singlewall object's on thingiverse, would be sad if you can't get them to work on a makerbot!

good luck!

Hi Roman! Thanks so much for that link!! I'm so new to this, so I really appreciate your help and pointers on the print. Your instructions were excellent- I pushed the settings on my print last time and it was quite fast. I will now work on making single-walls! I appreciate your kind help! Fantastic model, BTW! Brilliant Idea!

you are very welcome! thanks for the kind words!

Great job. Very cool.

Abs only? Is pla too stiff?

i printed about 10 of those, mostly with PLA... works perfect.
some i printed with PET... those were even more robust:)

This is beautiful. The train looks like it runs really well on it.
I need to print this just to play with the springiness.
Thanks.

it does! i did't use the sidewalls because it would not have been a "true" single-line print anymore:) and it seems it does not need them at all.
