Atari Yolk 14 tooth gear Repoductions

<< < (6/15) > >>

lilshawn:
much as anything else you get what you pay for...sure you can get yourself a $500 makerbot knockoff, but the items it produces, while good, are not great. nothing in comparison to the proper unit with the proper materials.

what are the thoughts on the laser polymerized type of 3D printer? while an older and more expensive technology, it's stands to reason it's quality could be much better than the ABS extruded models since the resolution would be much higher. I mean, I've never actually seen a part produced by this process.

34k:
They arrived yesterday and I installed C from the attached pics last night.

A: 3D printed from a different vendor
B: Randy's fully printed version
C: Randy's teeth-only version
D: Repro of the original (from them that shall not be named) that I got second-hand a while back

I have it installed per the pic. Randy's went in like the original or the D version repro.
Action is smooth (I used the original Atari Nyogel but thank you Randy for sending some lubricant!)

I will get some significant game-play in this weekend and report back.

Randy, if you don't mind me asking, what size nozzle did you print those with?

On my printer I have a 0.35 J-head (which prints very fine detail but takes forever on large prints). I ask b/c I just got a 0.5 J-head for X-mas that I still need to assemble and install. I am afraid I will be sacrificing some detail for some speed..

Xiaou2:
Lame.

  As the saying goes... You get what you pay for.

 The teeth look nothing like the properly made gears.  They are not deep enough, nor shaped properly.

 The worst part, is the thing is filled with voids.   If you think the original gears were prone to breaking... I wouldnt bet on these lasting a year.

 3D printing of this quality, is only good for prototypes, or temporary low level, low strain,  parts.

 You would be far better off doing gears on something like a waterjet or laser cutter.


Slippyblade:
Xiaou...  Do you have some kind of psychological issue where you have to belittle every single thing that comes into your field of view?  I don't think I've seen a single positive thing from you.  Ever.  Every post is, "This sucks", "That is junk", "Mines bigger/better", "You're doing it wrong"

You must live a very lonely life...
