Exciting engineering challenges with great prizes

Show off your skills and solve real design problems

Extreme Redesign: Engineering Secondary Education

Open to students worldwide, Extreme Redesign is an annual 3D printing challenge created
by Stratasys, Inc. that invites students to design an original piece of art, jewelry or
architecture, or to make an existing design better. This year, extreme redesign features 3
categories:
• Engineering: Secondary Education (middle/high school students)
• Engineering: Post-Secondary (university, college, or post-secondary students)
• Art, Jewelry & Architecture (student of any grade level)
Don't have access to a 3D printer? No problem! To enter, individual students or teams must
create and submit their designs files in .STL format with a compelling description
highlighting the designs inspiration, meaning and impact. The more info the better – images,
renderings, videos and screen shots of the design are encouraged!
Entries will be accepted through (April, 24, 2020), but the earlier you submit, the more
opportunity you have to get feedback on your design and have a chance to improve it and re-
upload improved files before the submission window closes.

Engineering: Secondary Education
Have you ever thought - I can make that better? Here is your chance to invent, innovate or improve something by re-engineering it to be printed in 3D in the annual Extreme Redesign Challenge. Consider different 3D printing methodologies (FDM, SLS, SLA and PolyJet) and materials available, and pick the best method for the production of your design. We are looking for sound designs that consider the tolerance and layer thickness capabilities of the 3D printer you’ll use, and includes calculations and documentation of design decisions related to those capabilities. Your entry should include a compelling description (written and/or video), illustrating design creativity & usefulness – does your design solve a problem or innovate on a current solution to make it better in some way.


Who Can Enter
This category is open to students (enrolled in person or coursework online) of all ages.
Entrants under the age of 18 must have their entries submitted by a parent or guardian over
the age of 18. You may enter this challenge individually, or as a design team. All team
members must be enrolled as a student in an educational institution or online program during
the semester/term in which they contribute to the design. The Challenge is not open to any
persons employed, past or present, as a professional in 3D printing.

    You can create anything you use that you believe that you can improve on design. Here are the results of last year, https://grabcad.com/challenges/extreme-redesign-engineering-post-secondary-education/results. You can create a Pencil holder, a Support for a camera, a pill container etc. It's completely up to you.

    Do designs have to be entirely 3D printed? I was thinking about making a design that incorporates PVC tubing. If so, does the entire assembly have to be within the 4.75x4.74x4.75 or each of the 3D printed components?

    Thank you for choosing my model as one of the finalists! @Jacob Carter, thanks for the feedback, especially the testing from your cousin. I'll make an effort to put some more miles on my pulleys and see where I can improve the design for more strength and durability. Also, congrats to all the other finalists!

    @Jacob Carter, I greatly appreciate your analysis of our design. We will keep these things in mind for any future iterations and projects. I was wondering if you could give any general tips on how to better optimize a print like this one; we actually did try to do so by doing things like keeping the design and mechanisms relatively simple and limiting the number of parts as much as we thought was practical, but I am completely open to critique and any recommendations you or anyone else may have so we can improve our future designs.

    Also, I was wondering if you could list some of the areas where there was extra mass so I could look into our design choices and take them into further consideration. When designing our device, we actually intentionally maintained mass in some areas for robustness and strength, although at the same time we tried to make sure that the design was not unnecessarily bulky or unwieldy.

    With regard to the poor stress results you experienced, our resources and limited time unfortunately did not allow for a comprehensive study of these forces on the gears and the rest of the mechanisms. When we have access to a 3D printer again (we are currently waiting for replacement parts), we will definitely try to make sure to print out design out and test it for further analysis. Is there a particular software program you use or recommend for the purpose of stress simulations?

    A description of how you fixed the apparent stress problem by rearranging the gears would really help us as well. The current gear train design resulted from careful efforts to make the gear train itself compact yet effective so the main body of the device could be a practical size (while at the same time not interfering with the rail and rack system).

    Concerning our choice of material, we decided to use PET-G because our research and our own experience showed that its strength, wide-spread availability, affordability, and safe, human-friendly nature proved it to be an overall solid choice. While parts made of this material (such as the gears) may eventually get worn out, I believe it is fair to say that PET-G would outlast many of its counterparts (filaments that are easily accessible, affordable, like PLA, ABS, and so on) when it comes to durability. The fact that the filament itself is relatively inexpensive and accessible, along with the fact that the parts prone to wear (like the gears) are relatively small and don’t take much filament or time to print, should solve any concerns about serious wearing or deformation. As we touched on in the description of the device, this ability to reprint any damaged or worn parts within a matter of hours really does highlight one of the great advantages of making a device like this through 3D printing! We could have recommended a stronger, more “exotic” filament for this device, but in the end we had to take into consideration that the vast majority of people’s 3D printers do not have the ability to print these rarer materials, nor do many have the money to purchase them.

    Regarding your final comment on the gears slipping, do you mean that they slipped out of alignment with the other gears, or that they slipped along the shafts they are on? This information would prove very helpful to us for any future design-related improvements.

    Again, I really appreciate your taking the time to analyze and critique our design, Jacob. I hope that I was able to adequately explain the logic behind some of our design and material choices. If you or anyone else has any other recommendations, critiques, or questions, I would love to hear them; I am always striving to improve and learn!

    The majority of college students wouldn't solve this task neither write some review.
    But luckily, out writing service GradeMiner https://grademiners.com/reviews provides qualified assistance for all the writing needs.
    Our writers are real professionals and devoted people. SO don't hesitate to reach us out any time you need it.
