The Archimedes screw is a water pump that allows water to be raised from a lower to higher elevation. It consists of a central shaft with a helical surface, which itself sits within a cylindrical channel. Your challenge, should you choose to accept it, is as follows:
In your submission, please indicate the version of Creo Parametric that you used to create your model.
This challenge was inspired by an Archimedes screw on display at the Pacific Science Center in Seattle:
Please submit a zip file of your submission as a reply to this post. If you choose to submit an assembly file only (no rendered image, rendered animation, or kinematic analysis movie), don’t forget to embed the components.
The submission period will end on Friday, September 8th.

Inspiration...
Interesting. Can you share your files?
I am going to be brave and be the first to post a model. Whil not quite complete, (no hardware and other finishing touches) here is what I created:
Creo 7.0 files attached.
Congratulations! You are the first person to submit a model of a solution!
Hi, Michael. Do you want to post your files so you can be considered along with the rest of the submissions?
Thanks,
Dave
Still need to figure out why the renderer adds the speckles...
Real time rendering works fine
I'd be more worried about the fact that rendering it either way put a big bend in the middle of the screw....🤣
I consider this correct light breaking at the surface of the water 😁
It is, the difference between the reflective/refractive/light transmissibility of air vs water, just busting yer chops. 🤣
I think if you use "denoise" and wait a bit the speckles should go away.
Please find attached the Creo files for the previous thread. The zip file also includes a simple MDX animation (rendered version still has speckles, it seems as "Denoise" works in real time rendering only....)
Have fun!
Dear PTC Community,
Hope you are doing well !
Thank you for arranging this activity, Here is my attempt to complete this challenge.
It's kind of "Eureka" moment for me to post the solution. (I don't literally mean 😁 like what Archimedes said to world by uttering "Eureka" back in ancient time)
This design is attempted to complete in basic mechanical design manner, which is followed in industry, can be considered as purely a concept design only and it is inspired to use "PTC Creo Parametric" basic and some special modules, ex. AFX/IFX., Render Studio & Mechanism Design/Design Animations. During this design, some machine elements like Bearings, couplings and Motor has been used as step files derived from common platforms like McMaster-Carr and manufactures online CAD-configurators (for electric motor & bearing) Selection & modeling of auxiliary components, geometry size is for visual purpose only, that does not involve any calculated results (except a 1.5-meter lift height as parameter to consider while modeling)
Whereas creating rendered video which is posted above was little challenging in the absence of recommended & supported GPU memory.
Overall assignment in this challenge also gives further task to understand the options used in detail. It was great learning experience.
Creo Parametric 9.0.4.0 version is used in this activity.Rendering-1
Rendering-2
Posting CAD files and one non-rendered animation for reference in this post
Everyone, in light of end of summer vacations, Labor Day, and kids going back to school, we have decided to extend the contest through Thursday, September 14th. If you still want in on the contest, please take a couple hours to create a submission and post it here.
Good luck and happy modeling!
Here is my submission although it is not compete. I used Creo 10.
Got a screenshot for those of use not lucky enough to work on the latest version of Creo?
Here is a screenshot.
It looks like the individual piece parts are missing. Can you try zipping up another file? Otherwise, you can embed the components. Thanks!
Thanks to everyone for participating. The challenge is now closed.
I am writing up the results. If you submitted an entry and would like me to use your real name instead of your PTC Community username, please send me a message through here.
We just happened to make a visit to the Pacific Science Center today. Here's another picture of their Archimedes screw. It's capable of conveying a surprising amount of water (if you spin it fast, which Ellie can't).
